[英]getting NoReverseMatch for a correct url and correct arguments
我已经仔细检查了我的代码,但在此时我仍然遇到NoReverseMatch错误,无法获得正确的URL和正确的参数。
这是我的URLConfig
url(r'profile/$', views.agent_profile, name='agent_profile'),
url(r'profile/(?P<pk>[A-Za-z0-9]+)/$', views.change_profile, name='change_profile'),
url(r'assign/(?P<pk>[A-Za-z0-9]+)/profile/(?P<profile>[A-Za-z0-9]+)/$', views.assign_profile, name='assign_profile'),
处理该请求的视图是:
def assign_profile(request, pk, profile):
agent = Agent.objects.get(pk=pk)
# profile = Profile.objects.filter(designation=profile)
# profile.agents = agent
return render(request,
'portfolio/change_profile.html',
{'agent': agent})
模板中的URL称为:
<li><a href={% url 'portfolio:assign_profile' pk=agent.code_agent profile="super_agent" %}>Super Agent</a></li>
错误如下:
NoReverseMatch at /portfolio/profile/1/
Reverse for 'assign_profile' with keyword arguments '{'pk': '1', 'profile': 'super_agent'}' not found. 1 pattern(s) tried: ['portfolio/assign/(?P<pk>[A-Za-z0-9]+)/profile/(?P<profile>[A-Za-z0-9]+)/$']

您拥有profile="super_agent"
,但是在您的正则表达式[A-Za-z0-9_]+
中不包含下划线。
url(r'assign/(?P<pk>[A-Za-z0-9]+)/profile/(?P<profile>[A-Za-z0-9_]+)/$', views.assign_profile, name='assign_profile'),
您还可以使用[\\w-]+
,它匹配大写AZ,小写az,数字0-9,连字符和下划线。 如果您的主键是整数,则[0-9]+
应该足够。 放在一起,您将:
url(r'assign/(?P<pk>[0-9]+)/profile/(?P<profile>[\w-]+)/$', views.assign_profile, name='assign_profile'),
