- issue1714899: Feature Request: Optional Change Note. Added a new quiet=True/False option for all property types. When quiet=True changes to the property will not be displayed in the:: confirmation banner (shown in green) when a change is made property change section of change note (nosy emails) web history display for an item. Note that this may confuse users if used on a property that is meant to be changed by a user. It is most useful on administrative properties that are changed by an auditor as part of a user generated change. Original patch by Daniel Diniz (ajaksu2) discussed also at: http://psf.upfronthosting.co.za/roundup/meta/issue249 Support for setting quiet when calling the class specifiers: E.G. prop=String(quiet=True) rather than:: prop=String() prop.quiet=True support for anydb backend, added tests, doc updates, support for ignoring quiet setting using showall=True in call to history() function in templates by John Rouillard. In addition to documenting quiet, I also documented required and default_value additions to the hyperdb property classes. Only place I could find is design.txt. Note tests for history in web interface are not done. It was manually checked but there are no automated tests. The template for setup is in db_test_base.py::testQuietJournal but it has no asserts. I need access to template.py::_HTMLItem::history() and I don't know how to do that. test_templates.py isn't helping me any at all and I want to get this patch in because it handles nicely an issue I have in the design of my own tracker. The issue is: The properties of an issue are displayed in framesets/subframes. The user can roll up the frameset leaving only the title bar. When the user saves the changes, the current state of the framesets (collapsed/uncollapsed) is saved to a property in the user's object. However there is no reason the user should see that this is updated since it's an administrative detail. Similarly, you could count the number of times an issue is reopened or reassigned. Updates to properties that are an indirect result of a user's change should not be displayed to the user as they can be confusing and distracting.
