python - NoReverseMatch after upgrading to Django 1.6 from 1.4 -

finally upgraded project 1.6 , i'm having trouble urls , class based views.

i have form starts this:

<form action="{{ project.get_absolute_url }}" method="post" id="editproject" >

and project model includes this:

@permalink def get_absolute_url(self):     return  ('project_url', (), {'slug': self.slug}) 

on trying load page i'll error:

noreversematch @ /teamslug1/projectslug1/teamid1/projectid1/ reverse 'project_url' arguments '()' , keyword arguments '{'slug': u'projectslug1'}' not found. 1 pattern(s) tried: ['(?p<teamslug>[^\\.]+)/(?p<projectslug>[^\\.]+)/(?p<teamid>[^\\.]+)/(?p<projectid>[^\\.]+)/$'] 

if wrap form variable in quotes:

<form action="{{ "project.get_absolute_url" }}" method="post" id="editproject" >

it won't error out on loading when post form it'll result in url this: http://0.0.0.0:5000/teamslug1/projectslug1/teamid1/projectid1/project.get_absolute_url, doesn't exist.

here's urls.py info:

url(r'^(?p<teamslug>[^\.]+)/(?p<projectslug>[^\.]+)/(?p<teamid>[^\.]+)/(?p<projectid>[^\.]+)/$', 'ideas.views.projects', name='project_url'),

any ideas?

this doesn't problem specific django 1.6 or class based views. problem get_absolute_url method doesn't match url pattern.

firstly, wrapping variable in quotes incorrect. django treats string, browser treats relative link, , posts form wrong url.

the project_url url pattern has 4 keyword arguments get_absolute_url method specifies slug, isn't 1 of arguments. expect get_absolute_url method like:

@permalink def get_absolute_url(self):     return  ('project_url', (), {'teamslug': self.teamslug,                                  'projectslug': self.projectslug,                                  'projectid': self.projectid,                                  'teamid ': self.teamid,     }) 

note docs recommend use reverse instead of permalink decorator.

from django.core.urlresolvers import reverse  def get_absolute_url(self):     return  reverse('project_url', kwargs={'teamslug': self.teamslug,                                            'projectslug': self.projectslug,                                            'projectid': self.projectid,                                            'teamid ': self.teamid,     })
