Django Reverse with arguments '()' and key

问题:

Hi I have an infuriating problem.

I have a url pattern like this:

# mproject/myapp.urls.py

url(r'^project/(?P<project_id>\d+)/$','user_profile.views.EditProject',name='edit_project'),

it works fine in the browser but for testing, when I do this in the shell:

from django.test import Client
from django.core.urlresolvers import reverse

client= Client()
response = client.get(reverse('edit_project'), project_id=4)

I get the dreaded:

NoReverseMatch: Reverse for 'edit_project' with arguments '()' and keyword arguments '{}' not found.

What am I missing here?

回答1:

You have to specify project_id:

reverse('edit_project', kwargs={'project_id':4})

This problems gave me great headache when i tried to use reverse for generating activation link and send it via email of course. So i think from tests.py it will be same. The correct way to do this is following:

from django.test import Client
from django.core.urlresolvers import reverse

#app name - name of the app where the url is defined
client= Client()
response = client.get(reverse('app_name:edit_project', project_id=4))

Resolve is also more straightforward

from django.urls import resolve

resolve('edit_project', project_id=4)
