URL not resolving correctly in Django URL - django

Question

I just tried the following in my AJAX update:
[Server]/secTypes/Update
This maps to the following url in URLS.py:
url(r'^secTypes/Update/', equity.views.updateSecTypes, name='updateSecTypes'),
This doesn't resolve to the following function in my view.
But when I change the URL expression to:
url(r'^su/', equity.views.updateSecTypes, name='updateSecTypes')
It works fine.
What in the URL resolver is not getting accurately mapped? Is it the forward slash?
I think it has to do with something related to the regex so if someone understands this better can help me that would be appreciated.

From the url patterns in your comments, it looks like you had another matching pattern before the one in your question.
There are two simple solution for this.
Move that first pattern down. Change this:
url(r'^secTypes/', equity.views.getSecTypes, name='getSecTypes'),
url(r'^secTypesAll/', equity.views.getSecTypesAll, name='getSecTypesAll'),
url(r'^secTypes/Update/', equity.views.updateSecTypes, name='updateSecTypes'),
url(r'^secTypes/Delete/', equity.views.deleteSecTypes, name='deleteSecTypes'),
url(r'^secTypes/Create/', equity.views.createSecTypes, name='createSecTypes'),
to this:
url(r'^secTypesAll/', equity.views.getSecTypesAll, name='getSecTypesAll'),
url(r'^secTypes/Update/', equity.views.updateSecTypes, name='updateSecTypes'),
url(r'^secTypes/Delete/', equity.views.deleteSecTypes, name='deleteSecTypes'),
url(r'^secTypes/Create/', equity.views.createSecTypes, name='createSecTypes'),
url(r'^secTypes/', equity.views.getSecTypes, name='getSecTypes'),
The order matters when resolving URL patterns and if an earlier one matches, the following ones are not processed.
Both r'^secTypes/' and r'^secTypes/Update/' matches the string 'secTypes/Update/' so you need to be careful to put the more specific one first and the more general one afterwards.
Update the regex to match the end of the URL string by adding a $ like this:
url(r'^secTypes/$', equity.views.getSecTypes, name='getSecTypes'),
url(r'^secTypesAll/$', equity.views.getSecTypesAll, name='getSecTypesAll'),
url(r'^secTypes/Update/$', equity.views.updateSecTypes, name='updateSecTypes'),
url(r'^secTypes/Delete/$', equity.views.deleteSecTypes, name='deleteSecTypes'),
url(r'^secTypes/Create/$', equity.views.createSecTypes, name='createSecTypes'),
This is the preferred solution since it would stop Django from matching a URL like secTypes/Update/foobar
However, if you have logic in the view that specifically uses the substring after the end of the URL pattern (i.e. foobar based on the above example), this wouldn't work.
