| 1013 ~~~~~~~~~~~~~~~ | |
| 1014 | |
| 1015 Macros are used in Roundup to save us from repeating the same common page | |
| 1016 stuctures over and over. The most common (and probably only) macro you'll use | |
| 1017 is the "icing" macro defined in the "page" template. | |
| 1018 | |
| 1019 Macros are generated and used inside your templates using special attributes | |
| 1020 similar to the `basic templating actions`_. In this case though, the | |
| 1021 attributes belong to the Macro Expansion Template Attribute Language, or | |
| 1022 METAL. The macro commands are: | |

| 1142 | 1329 The form variable |
| 1330 ::::::::::::::::: | |
| 1331 | |
| 1332 The form variable is a little special because it's actually a python | |
| 1333 FieldStorage object. That means that you have two ways to access its | |
| 1334 contents. For example, to look up the CGI form value for the variable | |
| 1335 "name", use the path expression:: | |
| 1336 | |
| 1337 request/form/name/value | |
| 1338 | |
| 1339 or the python expression:: | |
| 1340 | |
| 1341 python:request.form['name'].value | |
| 1342 | |
| 1343 Note the "item" access used in the python case, and also note the explicit | |
| 1344 "value" attribute we have to access. That's because the form variables are | |
| 1345 stored as MiniFieldStorages. If there's more than one "name" value in | |
| 1346 the form, then the above will break since ``request/form/name`` is actually a | |
| 1347 *list* of MiniFieldStorages. So it's best to know beforehand what you're | |
| 1348 dealing with. | |

| 1228 | 1737 Adding a new field to the classic schema |
| 1738 ---------------------------------------- | |
| 1100 | 1739 |
| 1740 This example shows how to add a new constrained property (ie. a selection of | |
| 1741 distinct values) to your tracker. | |
| 1098 | 1742 |
| 1743 Introduction | |
| 1100 | 1744 ~~~~~~~~~~~~ |
| 1098 | 1745 |
| 1746 To make the classic schema of roundup useful as a todo tracking system | |
| 1747 for a group of systems administrators, it needed an extra data field | |
| 1748 per issue: a category. | |
| 1749 | |
| 1750 This would let sysads quickly list all todos in their particular | |
| 1751 area of interest without having to do complex queries, and without | |
| 1752 relying on the spelling capabilities of other sysads (a losing | |
| 1753 proposition at best). | |
| 1754 | |
| 1755 Adding a field to the database | |
| 1100 | 1756 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 1757 |
| 1758 This is the easiest part of the change. The category would just be a plain | |
| 1759 string, nothing fancy. To change what is in the database you need to add | |

1764 add:: |
| 1098 | 1765 |
| 1766 category = Class(db, "category", name=String()) | |
| 1767 category.setkey("name") | |
| 1768 | |
| 1769 Here we are setting up a chunk of the database which we are calling | |
| 1770 "category". It contains a string, which we are refering to as "name" for | |
| 1771 lack of a more imaginative title. Then we are setting the key of this chunk | |
| 1772 of the database to be that "name". This is equivalent to an index for | |
| 1773 database types. This also means that there can only be one category with a | |
| 1774 given name. | |
| 1775 | |
| 1776 Adding the above lines allows us to create categories, but they're not tied | |
| 1777 to the issues that we are going to be creating. It's just a list of categories | |
| 1778 off on its own, which isn't much use. We need to link it in with the issues. | |
| 1779 To do that, find the lines in the ``open()`` function in ``dbinit.py`` which | |
| 1780 set up the "issue" class, and then add a link to the category:: | |
| 1781 | |
| 1782 issue = IssueClass(db, "issue", ... , category=Multilink("category"), ... ) | |
| 1783 | |
| 1784 The Multilink() means that each issue can have many categories. If you were | |
| 1785 adding something with a more one to one relationship use Link() instead. | |
| 1786 | |
| 1787 That is all you need to do to change the schema. The rest of the effort is | |
| 1788 fiddling around so you can actually use the new category. | |

| 1098 | 1822 Setting up security on the new objects |
| 1100 | 1823 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 1824 |
| 1825 By default only the admin user can look at and change objects. This doesn't | |
| 1826 suit us, as we want any user to be able to create new categories as | |
| 1827 required, and obviously everyone needs to be able to view the categories of | |
| 1828 issues for it to be useful. | |
| 1829 | |
| 1830 We therefore need to change the security of the category objects. This is | |
| 1831 also done in the ``open()`` function of ``dbinit.py``. | |
| 1832 | |
| 1833 There are currently two loops which set up permissions and then assign them | |
| 1834 to various roles. Simply add the new "category" to both lists:: | |
| 1835 | |
| 1836 # new permissions for this schema | |
| 1837 for cl in 'issue', 'file', 'msg', 'user', 'category': | |
| 1838 db.security.addPermission(name="Edit", klass=cl, | |
| 1839 description="User is allowed to edit "+cl) | |
| 1840 db.security.addPermission(name="View", klass=cl, | |
| 1841 description="User is allowed to access "+cl) | |
| 1842 | |
| 1843 # Assign the access and edit permissions for issue, file and message | |
| 1844 # to regular users now | |
| 1845 for cl in 'issue', 'file', 'msg', 'category': | |
| 1846 p = db.security.getPermission('View', cl) | |
| 1847 db.security.addPermissionToRole('User', p) | |
| 1848 p = db.security.getPermission('Edit', cl) | |
| 1849 db.security.addPermissionToRole('User', p) | |
| 1850 | |
| 1851 So you are in effect doing the following:: | |
| 1852 | |
| 1853 db.security.addPermission(name="Edit", klass='category', | |
| 1854 description="User is allowed to edit "+'category') | |
| 1855 db.security.addPermission(name="View", klass='category', | |
| 1856 description="User is allowed to access "+'category') | |
| 1857 | |
| 1858 which is creating two permission types; that of editing and viewing | |
| 1859 "category" objects respectively. Then the following lines assign those new | |
| 1860 permissions to the "User" role, so that normal users can view and edit | |
| 1861 "category" objects:: | |
| 1862 | |
| 1863 p = db.security.getPermission('View', 'category') | |
| 1864 db.security.addPermissionToRole('User', p) | |
| 1865 | |
| 1866 p = db.security.getPermission('Edit', 'category') | |
| 1867 db.security.addPermissionToRole('User', p) | |
| 1868 | |
| 1869 This is all the work that needs to be done for the database. It will store | |
| 1870 categories, and let users view and edit them. Now on to the interface | |
| 1871 stuff. | |
| 1872 | |
| 1873 Changing the web left hand frame | |
| 1100 | 1874 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 1875 |
| 1876 We need to give the users the ability to create new categories, and the | |
| 1877 place to put the link to this functionality is in the left hand function | |
| 1878 bar, under the "Issues" area. The file that defines how this area looks is | |
| 1879 ``html/page``, which is what we are going to be editing next. | |
| 1880 | |
| 1881 If you look at this file you can see that it contains a lot of "classblock" | |
| 1882 sections which are chunks of HTML that will be included or excluded in the | |
| 1883 output depending on whether the condition in the classblock is met. Under | |
| 1884 the end of the classblock for issue is where we are going to add the | |
| 1885 category code:: | |
| 1886 | |
| 1887 <p class="classblock" | |
| 1888 tal:condition="python:request.user.hasPermission('View', 'category')"> | |
| 1889 <b>Categories</b><br> | |
| 1890 <a tal:condition="python:request.user.hasPermission('Edit', 'category')" | |
| 1891 href="category?:template=item">New Category<br></a> | |
| 1892 </p> | |
| 1893 | |
| 1894 The first two lines is the classblock definition, which sets up a condition | |
| 1895 that only users who have "View" permission to the "category" object will | |
| 1896 have this section included in their output. Next comes a plain "Categories" | |
| 1897 header in bold. Everyone who can view categories will get that. | |
| 1898 | |
| 1899 Next comes the link to the editing area of categories. This link will only | |
| 1900 appear if the condition is matched: that condition being that the user has | |
| 1901 "Edit" permissions for the "category" objects. If they do have permission | |
| 1902 then they will get a link to another page which will let the user add new | |
| 1903 categories. | |
| 1904 | |
| 1905 Note that if you have permission to view but not edit categories then all | |
| 1906 you will see is a "Categories" header with nothing underneath it. This is | |
| 1907 obviously not very good interface design, but will do for now. I just claim | |
| 1908 that it is so I can add more links in this section later on. However to fix | |
| 1909 the problem you could change the condition in the classblock statement, so | |
| 1910 that only users with "Edit" permission would see the "Categories" stuff. | |
| 1911 | |
| 1912 Setting up a page to edit categories | |
| 1100 | 1913 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 1914 |
| 1915 We defined code in the previous section which let users with the | |
| 1916 appropriate permissions see a link to a page which would let them edit | |
| 1917 conditions. Now we have to write that page. | |
| 1918 | |
| 1919 The link was for the item template for the category object. This translates | |
| 1920 into the system looking for a file called ``category.item`` in the ``html`` | |
| 1921 tracker directory. This is the file that we are going to write now. | |
| 1922 | |

| 1961 Next we need the actual field that the user is going to enter the new | |
| 1962 category. The "context.name.field(size=60)" bit tells roundup to generate a | |
| 1963 normal HTML field of size 60, and the contents of that field will be the | |
| 1964 "name" variable of the current context (which is "category"). The upshot of | |
| 1965 this is that when the user types something in to the form, a new category | |
| 1966 will be created with that name:: | |

| 2020 This is quite a lot to just ask the user one simple question, but | |
| 2021 there is a lot of setup for basically one line (the form line) to do | |
| 2022 its work. To add another field to "category" would involve one more line | |
| 2023 (well maybe a few extra to get the formatting correct). | |
| 2024 | |
| 2025 Adding the category to the issue | |
| 1100 | 2026 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 2027 |
| 2028 We now have the ability to create issues to our hearts content, but | |
| 2029 that is pointless unless we can assign categories to issues. Just like | |
| 2030 the ``html/category.item`` file was used to define how to add a new | |
| 2031 category, the ``html/issue.item`` is used to define how a new issue is | |
| 2032 created. | |
| 2033 | |
| 2034 Just like ``category.issue`` this file defines a form which has a table to lay | |
| 2035 things out. It doesn't matter where in the table we add new stuff, | |
| 2036 it is entirely up to your sense of aesthetics:: | |
| 2037 | |
| 2038 <th nowrap>Category</th> | |
| 2039 <td><span tal:replace="structure context/category/field" /> | |
|

|
2040 <span tal:replace="structure db/category/classhelp" /> |
| 1098 | 2041 </td> |
| 2042 | |
| 2043 First we define a nice header so that the user knows what the next section | |
| 2044 is, then the middle line does what we are most interested in. This | |
| 2045 ``context/category/field`` gets replaced with a field which contains the | |
| 2046 category in the current context (the current context being the new issue). | |
| 2047 | |
| 2048 The classhelp lines generate a link (labelled "list") to a popup window | |
| 2049 which contains the list of currently known categories. | |
| 2050 | |
| 2051 Searching on categories | |
| 1100 | 2052 ~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 2053 |
| 2054 We can add categories, and create issues with categories. The next obvious | |
| 2055 thing that we would like to be would be to search issues based on their | |
| 2056 category, so that any one working on the web server could look at all | |
| 2057 issues in the category "Web" for example. | |
| 2058 | |
| 2059 If you look in the html/page file and look for the "Search Issues" you will | |
| 2060 see that it looks something like ``<a href="issue?:template=search">Search | |
| 2061 Issues</a>`` which shows us that when you click on "Search Issues" it will | |
| 2062 be looking for a ``issue.search`` file to display. So that is indeed the file | |
| 2063 that we are going to change. | |
| 2064 | |
| 2065 If you look at this file it should be starting to seem familiar. It is a | |
| 2066 simple HTML form using a table to define structure. You can add the new | |
| 2067 category search code anywhere you like within that form:: | |
| 2068 | |
| 2069 <tr> | |
| 2070 <th>Category:</th> | |
| 2071 <td> | |
| 2072 <select name="category"> | |
| 2073 <option value="">don't care</option> | |
| 2074 <option value="">------------</option> | |
| 2075 <option tal:repeat="s db/category/list" tal:attributes="value s/name" | |
| 2076 tal:content="s/name">category to filter on</option> | |
| 2077 </select> | |
| 2078 </td> | |
| 2079 <td><input type="checkbox" name=":columns" value="category" checked></td> | |
| 2080 <td><input type="radio" name=":sort" value="category"></td> | |
| 2081 <td><input type="radio" name=":group" value="category"></td> | |
| 2082 </tr> | |
| 2083 | |
| 2084 Most of this is straightforward to anyone who knows HTML. It is just | |
| 2085 setting up a select list followed by a checkbox and a couple of radio | |
| 2086 buttons. | |
| 2087 | |
| 2088 The ``tal:repeat`` part repeats the tag for every item in the "category" | |
| 2089 table and setting "s" to be each category in turn. | |
| 2090 | |
| 2091 The ``tal:attributes`` part is setting up the ``value=`` part of the option tag | |
| 2092 to be the name part of "s" which is the current category in the loop. | |
| 2093 | |
| 2094 The ``tal:content`` part is setting the contents of the option tag to be the | |
| 2095 name part of "s" again. For objects more complex than category, obviously | |
| 2096 you would put an id in the value, and the descriptive part in the content; | |
| 2097 but for category they are the same. | |
| 2098 | |
| 2099 Adding category to the default view | |
| 1100 | 2100 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 1098 | 2101 |
| 2102 We can now add categories, add issues with categories, and search issues | |
| 2103 based on categories. This is everything that we need to do, however there | |
| 2104 is some more icing that we would like. I think the category of an issue is | |
| 2105 important enough that it should be displayed by default when listing all | |
| 2106 the issues. | |
| 2107 | |
| 2108 Unfortunately, this is a bit less obvious than the previous steps. The code | |
| 2109 defining how the issues look is in ``html/issue.index``. This is a large table | |
| 2110 with a form down the bottom for redisplaying and so forth. | |
| 2111 | |
| 2112 Firstly we need to add an appropriate header to the start of the table:: | |
| 2113 | |
| 2114 <th tal:condition="request/show/category">Category</th> | |
| 2115 | |
| 2116 The condition part of this statement is so that if the user has selected | |
| 2117 not to see the Category column then they won't. | |
| 2118 | |
| 2119 The rest of the table is a loop which will go through every issue that | |
| 2120 matches the display criteria. The loop variable is "i" - which means that | |
| 2121 every issue gets assigned to "i" in turn. | |
| 2122 | |
| 2123 The new part of code to display the category will look like this:: | |
| 2124 | |
| 2125 <td tal:condition="request/show/category" tal:content="i/category"></td> | |
| 2126 | |
| 2127 The condition is the same as above: only display the condition when the | |
| 2128 user hasn't asked for it to be hidden. The next part is to set the content | |
| 2129 of the cell to be the category part of "i" - the current issue. | |
| 2130 | |
| 2131 Finally we have to edit ``html/page`` again. This time to tell it that when the | |
| 2132 user clicks on "Unnasigned Issues" or "All Issues" that the category should | |
| 2133 be displayed. If you scroll down the page file, you can see the links with | |
| 2134 lots of options. The option that we are interested in is the ``:columns=`` one | |
| 2135 which tells roundup which fields of the issue to display. Simply add | |
| 2136 "category" to that list and it all should work. | |
| 2137 | |
| 2138 | |
| 1100 | 2139 Adding in state transition control |
| 2140 ---------------------------------- | |
| 2141 | |
| 2142 Sometimes tracker admins want to control the states that users may move issues | |
| 2143 to. | |
| 2144 | |
| 2145 1. add a Multilink property to the status class:: | |
| 2146 | |
| 2147 stat = Class(db, "status", ... , transitions=Multilink('status'), ...) | |

2152 b. using the roundup-admin "set" command. |
| 1100 | 2153 |
| 2154 2. add an auditor module ``checktransition.py`` in your tracker's | |
| 2155 ``detectors`` directory:: | |
| 2156 | |
| 2157 def checktransition(db, cl, nodeid, newvalues): | |
| 2158 ''' Check that the desired transition is valid for the "status" | |
| 2159 property. | |
| 2160 ''' | |
| 2161 if not newvalues.has_key('status'): | |
| 2162 return | |
| 2163 current = cl.get(nodeid, 'status') | |
| 2164 new = newvalues['status'] | |
| 2165 if new == current: | |
| 2166 return | |
| 2167 ok = db.status.get(current, 'transitions') | |
| 2168 if new not in ok: | |
| 2169 raise ValueError, 'Status not allowed to move from "%s" to "%s"'%( | |
| 2170 db.status.get(current, 'name'), db.status.get(new, 'name')) | |
| 2171 | |
| 2172 def init(db): | |
| 2173 db.issue.audit('set', checktransition) | |
| 2174 | |
| 2175 3. in the ``issue.item`` template, change the status editing bit from:: | |
| 2176 | |
| 2177 <th nowrap>Status</th> | |
| 2178 <td tal:content="structure context/status/menu">status</td> | |
| 2179 | |
| 2180 to:: | |
| 2181 | |
| 2182 <th nowrap>Status</th> | |
| 2183 <td> | |

| 2349 Using an external password validation source | |
| 2350 -------------------------------------------- | |
| 2351 | |
| 2352 We have a centrally-managed password changing system for our users. This | |
| 2353 results in a UN*X passwd-style file that we use for verification of users. | |
| 2354 Entries in the file consist of ``name:password`` where the password is | |
| 2355 encrypted using the standard UN*X ``crypt()`` function (see the ``crypt`` | |
| 2356 module in your Python distribution). An example entry would be:: | |
| 2357 | |
| 2358 admin:aamrgyQfDFSHw | |
| 2359 | |
| 2360 Each user of Roundup must still have their information stored in the Roundup | |
| 2361 database - we just use the passwd file to check their password. To do this, we | |
| 2362 add the following code to our ``Client`` class in the tracker home | |
| 2363 ``interfaces.py`` module:: | |
| 2364 | |
| 2365 def verifyPassword(self, userid, password): | |
| 2366 # get the user's username | |
| 2367 username = self.db.user.get(userid, 'username') | |
| 2368 | |
| 2369 # the passwords are stored in the "passwd.txt" file in the tracker | |
| 2370 # home | |
| 2371 file = os.path.join(self.db.config.TRACKER_HOME, 'passwd.txt') | |
| 2372 | |
| 2373 # see if we can find a match | |
| 2374 for ent in [line.strip().split(':') for line in open(file).readlines()]: | |
| 2375 if ent[0] == username: | |
| 2376 return crypt.crypt(password, ent[1][:2]) == ent[1] | |
| 2377 | |
| 2378 # user doesn't exist in the file | |
| 2379 return 0 | |
| 2380 | |
| 2381 What this does is look through the file, line by line, looking for a name that | |
| 2382 matches. | |
| 2383 | |
| 2384 We also remove the redundant password fields from the ``user.item`` template. | |
| 2385 | |

| 1262 | 2477 Adding a time log to your issues |
| 2478 -------------------------------- | |
| 2479 | |
| 2480 We want to log the dates and amount of time spent working on issues, and be | |
| 2481 able to give a summary of the total time spent on a particular issue. | |
| 2482 | |
| 2483 1. Add a new class to your tracker ``dbinit.py``:: | |
| 2484 | |
| 2485 # storage for time logging | |
| 2486 timelog = Class(db, "timelog", period=Interval()) | |
| 2487 | |
| 2488 Note that we automatically get the date of the time log entry creation | |
| 2489 through the standard property "creation". | |
| 2490 | |
| 2491 2. Link to the new class from your issue class (again, in ``dbinit.py``):: | |
| 2492 | |
| 2493 issue = IssueClass(db, "issue", | |
| 2494 assignedto=Link("user"), topic=Multilink("keyword"), | |
| 2495 priority=Link("priority"), status=Link("status"), | |
| 2496 times=Multilink("timelog")) | |
| 2497 | |
| 2498 the "times" property is the new link to the "timelog" class. | |
| 2499 | |
| 2500 3. We'll need to let people add in times to the issue, so in the web interface | |
| 2501 we'll have a new entry field, just below the change note box:: | |
| 2502 | |
| 2503 <tr> | |
| 2504 <th nowrap>Time Log</th> | |
| 2505 <td colspan=3><input name=":timelog"> | |
| 2506 (enter as "3y 1m 4d 2:40:02" or parts thereof) | |
| 2507 </td> | |
| 2508 </tr> | |
| 2509 | |
| 2510 Note that we've made up a new form variable, but since we place a colon ":" | |
| 2511 in front of it, it won't clash with any existing property variables. The | |
| 2512 names you *can't* use are ``:note``, ``:file``, ``:action``, ``:required`` | |
| 2513 and ``:template``. These variables are described in the section | |
| 2514 `performing actions in web requests`_. | |
| 2515 | |
| 2516 4. We also need to handle this new field in the CGI interface - the way to | |
| 2517 do this is through implementing a new form action (see `Setting up a | |
| 2518 "wizard" (or "druid") for controlled adding of issues`_ for another example | |
| 2519 where we implemented a new CGI form action). | |
| 2520 | |
| 2521 In this case, we'll want our action to: | |
| 2522 | |
| 2523 1. create a new "timelog" entry, | |
| 2524 2. fake that the issue's "times" property has been edited, and then | |
| 2525 3. call the normal CGI edit action handler. | |
| 2526 | |
| 2527 The code to do this is:: | |
| 2528 | |
| 2529 actions = client.Client.actions + ( | |
| 2530 ('edit_with_timelog', 'timelogEditAction'), | |
| 2531 ) | |
| 2532 | |
| 2533 def timelogEditAction(self): | |
| 2534 ''' Handle the creation of a new time log entry if necessary. | |
| 2535 | |
| 2536 If we create a new entry, fake up a CGI form value for the altered | |
| 2537 "times" property of the issue being edited. | |
| 2538 | |
| 2539 Punt to the regular edit action when we're done. | |
| 2540 ''' | |
| 2541 # if there's a timelog value specified, create an entry | |
| 2542 if self.form.has_key(':timelog') and \ | |
| 2543 self.form[':timelog'].value.strip(): | |
| 2544 period = Interval(self.form[':timelog'].value) | |
| 2545 # create it | |
| 2546 newid = self.db.timelog.create(period=period) | |
| 2547 | |
| 2548 # if we're editing an existing item, get the old timelog value | |
| 2549 if self.nodeid: | |
| 2550 l = self.db.issue.get(self.nodeid, 'times') | |
| 2551 l.append(newid) | |
| 2552 else: | |
| 2553 l = [newid] | |
| 2554 | |
| 2555 # now make the fake CGI form values | |
| 2556 for entry in l: | |
| 2557 self.form.list.append(MiniFieldStorage('times', entry)) | |
| 2558 | |
| 2559 # punt to the normal edit action | |
| 2560 return self.editItemAction() | |
| 2561 | |
| 2562 you add this code to your Client class in your tracker's ``interfaces.py`` | |
| 2563 file. | |
| 2564 | |
| 2565 5. You'll also need to modify your ``issue.item`` form submit action so it | |
| 2566 calls the time logging action we just created:: | |
| 2567 | |
| 2568 <tr> | |
| 2569 <td> </td> | |
| 2570 <td colspan=3> | |
| 2571 <tal:block tal:condition="context/id"> | |
| 2572 <input type="hidden" name=":action" value="edit_with_timelog"> | |
| 2573 <input type="submit" name="submit" value="Submit Changes"> | |
| 2574 </tal:block> | |
| 2575 <tal:block tal:condition="not:context/id"> | |
| 2576 <input type="hidden" name=":action" value="new"> | |
| 2577 <input type="submit" name="submit" value="Submit New Issue"> | |
| 2578 </tal:block> | |
| 2579 </td> | |
| 2580 </tr> | |
| 2581 | |
| 2582 Note that the "context/submit" command usually handles all that for you - | |
| 2583 isn't it handy? The important change is setting the action to | |
| 2584 "edit_with_timelog" for edit operations (where the item exists) | |
| 2585 | |
