420 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 421 |
| 422 **Change the type of a property** | |
| 423 Property types must *never* be changed - the database simply doesn't take | |
| 424 this kind of action into account. Note that you can't just remove a | |
| 425 property and re-add it as a new type either. If you wanted to make the | |
| 426 assignedto property a Multilink, you'd need to create a new property | |
| 427 assignedto_list and remove the old assignedto property. | |
| 428 | |
| 429 | |
| 430 What you can do to the schema | |
| 431 ----------------------------- | |
| 432 | |
| 433 Your schema may be changed at any time before or after the tracker has been | |
| 434 initialised (or used). You may: | |
| 435 | |
| 436 **Add new properties to classes, or add whole new classes** | |
| 437 This is painless and easy to do - there are generally no repurcussions | |
| 438 from adding new information to a tracker's schema. | |
| 439 | |
| 440 **Remove properties** | |
| 441 Removing properties is a little more tricky - you need to make sure that | |
| 442 the property is no longer used in the `web interface`_ *or* by the | |
| 443 detectors_. | |
| 444 | |
| 445 | |

| 632 | |
| 633 Auditors are called with the arguments:: | |
| 634 | |
| 635 audit(db, cl, itemid, newdata) | |
| 636 | |
| 637 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 638 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 639 property names to values. | |
| 640 | |
| 641 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 642 newdata contains all of the initial property values with which the item | |
| 643 is about to be created. | |
| 644 | |
| 645 For a ``set()`` operation, newdata contains only the names and values of | |
| 646 properties that are about to be changed. | |
| 647 | |
| 648 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 649 | |
| 650 Reactors are called with the arguments:: | |
| 651 | |
| 652 react(db, cl, itemid, olddata) | |
| 653 | |
| 654 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 655 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 656 property names to values. | |
| 657 | |
| 658 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 659 newly-created item and ``olddata`` is None. | |
| 660 | |
| 661 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 662 values of properties that were changed. | |
| 663 | |
| 664 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |
| 665 the retired or restored item and ``olddata`` is None. | |

1916 The form variable is a bit special because it's actually a python |
| 1142 | 1917 FieldStorage object. That means that you have two ways to access its |
| 1918 contents. For example, to look up the CGI form value for the variable | |
| 1919 "name", use the path expression:: | |
| 1920 | |
| 1921 request/form/name/value | |
| 1922 | |
| 1923 or the python expression:: | |
| 1924 | |
