Various hacks to alter Ticket form behaviour and Ticket Permissions
Note: This hack is available for adoption.
Trac 0.11 provides developers and administrators with the ability to apply Genshi Transformers to the templates before they are presented to the user. This plugin adds the ability to tweak any of the Ticket fields, be they custom or standard, in the following ways:
- disable - The field won't be editable.
- hide - The field will be invisible.
- label - Rename a field, in particular one of the built-in fields.
- notice - Add a small notice below a field.
- permission - Set a permission that is required to edit that specific field. This is particularly useful in an environment where you let users set severity, so they need TICKET_CHGPROP, but you only want certain people to be able to edit the Priority.
The plugin also lets you define arbitrary permissions, say MASTER_OF_PRIORITIES, if you want to require someone to have such a custom permission to edit a certain field.
The plugin can also deny access to certain ticket types by permissions using the ticket_type ini setting.
If you have any issues, create a new ticket. Please cc yourself if you're anonymous or you won't be notified of when I respond.

Trac 0.11 or later.
The easiest way to install the BlackMagicTicketTweaksPlugin is to point easy_install at the t-h.o SVN repository, such as:
Alternatively, you may download the source and go into the Trac 0.11 directory and then run:
python setup.py install
After you have installed the BlackMagicTicketTweaksPlugin, you must enable it. You can do so in the Administration panel of Trac, or in the trac.ini file by adding:
[components] blackmagic.* = enabled
Any fields that you would like to tweak with this plugin must be listed in the tweaks option of the [blackmagic] section in your TracIni. This list is comma-separated and lower case. For example:
[blackmagic] tweaks = cc, priority, severity
Next you must specify all the actions that you want performed on those fields. You can have as many actions as you like.
The actions are specified as <field>.<action> = <value>:
[blackmagic] tweaks = priority priority.permission = TRAC_ADMIN
The following are considered True settings in trac.ini:
They are all case insensitive.
The following actions are supported:
- If True, the field will be present and its value shown but it won't be editable. By default the label will be striked out, but if you set the gray_disabled option to some value, that color will be used instead. Suggested value is #cccccc.
- If True, the field will be completely removed and so not settable and invisible.
- The label for the field will be renamed to this value. Not useful for the custom fields, but it lets you adjust the default fields names.
- Adds a small notice under the field; useful for annotations on the field.
- A comma-separated list of permissions that the user must have at least one of to edit this field. If they do not, the field will be disabled (as above). This allows per-field permissions.
- This only means something on a field with a permission action set. In this case, it determines how to handle if the user has no such permission. Valid options are either 'disable' (default) or 'hide', both treated as if the field had such an action set as above.
You may create new permissions in Trac for use above (or anywhere you like) by specifying the permission option, as in:
[blackmagic] permissions = TICKET_CHG_PRIORITY, TICKET_CHG_CC
This feature is also available in the Trac core as of 0.12, see t:TracPermissions#CreatingNewPrivileges for more details.
To deny access to a ticket type by permission use the following options:
ticket_type.* = PERMISSION replacing * with the ticket type, for example defect. So to only allow users with the TICKET_MODIFY permission access to defect tickets you would set the following:
[blackmagic] ticket_type.defect = TICKET_MODIFY
Denying access to a ticket type will prevent users from seeing them in reports, viewing the tickets of that type and creating tickets of that type.
Currently the ticket_type.* option can only hold one permission, if you want a comma separated list raise a ticket and request it.
To use this option you will need to add BlackMagicTicketTweaks to the permission_policies option in the [trac] section of the trac.ini file:
[trac] permission_policies = BlackMagicTicketTweaks, DefaultPermissionPolicy
[blackmagic] permissions = MASTER_OF_PERMISSIONS, TICKET_RAISE_DEFECT tweaks = severity, priority priority.tip = The priority is the Project-defined importance of the issue, and in general the order in which things will tend to be done. severity.tip = The severity is how important this issue is to the customer or you. priority.permission = MASTER_OF_PERMISSIONS ticket_type.defect = TICKET_RAISE_DEFECT ticket_type.task = TICKET_ADMIN
