| 372 What you can't do to the schema | |
| 373 ------------------------------- | |
| 374 | |
| 375 You must never: | |
| 376 | |
| 377 **Remove the users class** | |
| 378 This class is the only *required* class in Roundup. Similarly, its | |
| 379 username, password and address properties must never be removed. | |
| 380 | |
| 381 **Change the type of a property** | |
| 382 Property types must *never* be changed - the database simply doesn't take | |
| 383 this kind of action into account. Note that you can't just remove a | |
| 384 property and re-add it as a new type either. If you wanted to make the | |
| 385 assignedto property a Multilink, you'd need to create a new property | |
| 386 assignedto_list and remove the old assignedto property. | |
| 387 | |
| 388 | |
| 389 What you can do to the schema | |
| 390 ----------------------------- | |
| 391 | |
| 392 Your schema may be changed at any time before or after the tracker has been | |
| 393 initialised (or used). You may: | |
| 394 | |
| 395 **Add new properties to classes, or add whole new classes** | |
| 396 This is painless and easy to do - there are generally no repurcussions | |
| 397 from adding new information to a tracker's schema. | |
| 398 | |
| 399 **Remove properties** | |
| 400 Removing properties is a little more tricky - you need to make sure that | |
| 401 the property is no longer used in the `web interface`_ *or* by the | |
| 402 detectors_. | |

1788 The form variable is a bit special because it's actually a python |

| 1790 contents. For example, to look up the CGI form value for the variable | |
| 1791 "name", use the path expression:: | |
| 1792 | |
| 1793 request/form/name/value | |
| 1794 | |
