Please include more documentation

[javierurien@…]

Hello,

I am trying to use invalid_if, invalid_when and I don't quite understand how it works. It would be really great to have more verbose documentation on the subject.

Example of what I want to do; I want to restrict users adding hours (by increment of the hours field) to a task ticket when the estimated_hours field is zero.

TIA

It appears this is not yet supported. It might look something like:

hours.invalid_when_estimate = 0

Two options for this narrow use-case:

• Implement server-side validation in ITicketManipulator.
• Extend DynamicFieldsPlugin with a new Rule. See IRule interface in dynamicfieldsplugin/trunk/dynfields/rules.py​.
