The following single-file plugin will redirect to the default handler when
//Submit changes// is pressed on the ticket page. It will not redirect on
ticket creation, comment edit and comment deletion.
from trac.core import Component, implements
from trac.ticket.web_ui import TicketModule
from trac.web.api import IRequestFilter
class RedirectOnTicketSave(Component):
implements(IRequestFilter)
def pre_process_request(self, req, handler):
if handler is TicketModule(self.env) \
and req.method == 'POST' and 'submit' in req.args \
and req.args['submit'] == 'Submit changes' \
and not req.args.get('preview'):
req.add_redirect_listener(ticket_save_listener)
return handler
def post_process_request(self, req, template, data, content_type):
return template, data, content_type
def ticket_save_listener(req, url, permanent):
if ticket_save_listener in req.redirect_listeners:
req.redirect_listeners.remove(ticket_save_listener)
req.redirect(req.href())
If I misunderstood your need, and instead you want to redirect on ticket
creation, you'll need to modify the conditions in pre_process_request. The
change req.args['submit'] == 'Submit changes' -> req.args['submit'] ==
'Create ticket' should be sufficient. Additionally, the code below adds a
notice to indicate that the ticket has been created.
from trac.core import Component, implements
from trac.ticket.web_ui import TicketModule
from trac.util.translation import _
from trac.web.api import IRequestFilter
from trac.web.chrome import add_notice
class RedirectOnTicketSave(Component):
implements(IRequestFilter)
def pre_process_request(self, req, handler):
if handler is TicketModule(self.env) \
and req.method == 'POST' and 'submit' in req.args \
and req.args['submit'] == 'Create ticket' \
and not req.args.get('preview'):
req.add_redirect_listener(ticket_save_listener)
return handler
def post_process_request(self, req, template, data, content_type):
return template, data, content_type
def ticket_save_listener(req, url, permanent):
if ticket_save_listener in req.redirect_listeners:
req.redirect_listeners.remove(ticket_save_listener)
id = url.split('/')[-1]
add_notice(req, _("Ticket #%(id)s has been created.", id=id))
req.redirect(req.href())
