How to request URL of previous page visited and store parts of it as a ForeignKey?

I have a django application that has an architecture:

Myapp.com/< uniquepageURL>

For posting new things to the page:

Myapp.com/< uniquepageURL>/post

For commenting on a specific post on a page

Myapp.com/< uniquepageURL>/comment< ID# of the post>

For example, if you are commenting on the post that is stored in the database with an ID of 22 then the URL should look like:

Myapp.com/< uniquepageURL>/comment22

This is how I’ve decided to map my urls. Is there a better/simpler way to do it? The < uniquepageURL> is also the ForeignKey of the post object in my models. What I am having trouble with is figuring out how to use the request function in django to look at what the url was so as to gain information from it, namely for posts which uniquepage it is from so I can save the value into the foreignkey field and for comments which post ID it is a comment of. What would the views for each look like? Here is my urls.py. For posts:

url(r'^(?P<uniquepageURL>[a-zA-Z0-9_.-]*)/post/$', views.post, name='post')

for comments:

url(r'^(?P<uniquepageURL>[a-zA-Z0-9_./-]*)/comment(?P<post.pk>[0-9]*)/$', views.comment, name='comment')name='comment')ts:

I think the post.pk part is wrong since it returns an error. But I can fix that myself hopefully if I can figure out how to get the post section working at least.

Be aware that the ?P<uniquepageURL> syntax indicates a named group; Django will attempt to match that name to arguments in the view function (see https://docs.djangoproject.com/en/1.7/topics/http/urls/#named-groups).

So, to get that value passed to your view function, simply include a parameter uniquepageURL. Note that means post.pk won't work as a name; consider post_id as an alternative. (Though I supposed you could use a **kwargs construct and get at the value with kwargs['post.pk']).

That said, if you do need other information from the request URL, I think the value you are looking for is request.path (which presumes your signature is def comment(request, uniquepageURL, post_id) or similar.
