无法使用{％url％}模板标记正确生成带有捕获参数的URL

Question

I'm running into an issue with supplying captured URL parameters through template tags. I have a URL dispatch with a captured parameter that hands off to another URL dispatch with include() that does not have any captured parameters:

nodemanager.urls: url(r'^(?P<node_id>\\d+)/rank/', include('ranking.urls')),

ranking.urls: url(r'^setup$', views.setup, name='setup'),

I am using {% url 'setup' node_id=node.id %} in my template which creates the error:

TypeError at /stage1/node/5/rank/setup

setup() got an unexpected keyword argument 'node_id'

If I take out the keyword argument and just use: {% url 'setup' %} , the landing page fails to load and I get the (predictable) error:

NoReverseMatch at /stage1/

Reverse for 'setup' with arguments '()' and keyword arguments '{}' not found. 1 pattern(s) >tried: ['stage1/node/(?P\\d+)/rank/setup$']

I know that I need to supply the parameter for node_id to properly reverse the URL. However, the named url "setup" in my ranking app doesn't take any parameters, but the URL that includes it (in the nodemanager app) does.

How would I properly pass the node_id keyword argument using a template tag that points to stage1/node/5/rank/setup , ie something of the form {% url 'setup' ... %} . Can I do this?

Let me know if I need to post more context code; I tried to include (what I thought) are the relevant parts.

Answer 1

The original error is not due to the URL reversing, but comes when the view is actually called. This is probably because you have not declared it to take a node_id argument. It should be like this:

def setup(request, node_id):
    ...

Once you've fixed that, the original url tag syntax should work.
