Conditionally display fields based on ticket type
With the help of this Trac plugin you can hide or show fields when creating or viewing a ticket, depending on the ticket type. Only the presentation changes, not the contents of the ticket.
This plugin is standalone; the patch blackmagic-conditionalfields.patch in https://trac-hacks.org/ticket/2486 did not match with newer releases of Trac 0.11.
Some problems reported about the more powerful DynamicFieldsPlugin (bad scaling for many fields, malfunction if fields are internally sorted, clearing value of hidden fields) should not occur here.
It should be easy to extend this plugin, e.g. for dependence on other parameters than ticket type.
The plugin was tested under Trac 0.12 and 0.11.
If you have any issues, create a new ticket.
Download the zipped source from here.
First, configure trac.ini as in this example:
[components] condfieldsgenshi.* = enabled ... [condfieldsgenshi] tweaks = field1, field2 default = disable field1.type_cond = defect field2.type_cond = task
Now field1 will be shown only if the ticket type is defect, field2 only if the ticket type is task.
default = disable
means that the field listed under tweaks are NOT shown by default.
The default value is default = enable.
To disable/enable a field independent of the ticket type, simply write a line like:
field1.type_cond = None
(supposed there is no None type :-).
When you change the ticket type, you must type preview resp. submit before you can see the effect of of condfieldsgenshi.
Bug fix done for type field
When the ticket type is given as an URL parameter only:
and the ticket type field is disabled, this plugin works nevertheless (in contrast to the CondFieldsPlugin).
The type field label is extended by (Fixed) in this case now.
