Happy to assist—a few notes/questions up-front:
- It's much easier to troubleshoot if you provide the full stack-trace,
as is. It helps answer questions like
- Which URL were you requesting that ultimately gave you this 404?
- Which URL patterns were "tried" or were regex-compared to the reqest
- It looks like you're trying to capture task_id from the url (e.g. "
api/1/" -> task_id = 1). You should use captured_parameters
<https://docs.djangoproject.com/en/1.8/topics/http/urls/#captured-parameters>for
this (i.e. "url(r'^(?P<task_id>\d{1,2})/$', api)")
- Review the Django docs for how views are defined
<https://docs.djangoproject.com/en/1.8/topics/http/views/>; Instead of
(self,
task_id) as your api view arguments you probably meant (request,
task_id).
- Note that '$' ends a regular expression, so calls like "api/1/detail/"
will 404.
- Your regex is requiring a closing slash on the url, which is okay for
the most part, but "api/1" will not work if you've modified the APPEND_SLASH
setting
<https://docs.djangoproject.com/en/dev/ref/settings/#append-slash>.
