You cannot access a variable like this in a template.
There is also no point in trying to access an url using url providing an
url. Your url pattern is called 'post_detail'.

Try something like:
{% url 'post_detail' pk=post.pk %}

More information is available in the docs:
https://docs.djangoproject.com/en/1.9/ref/templates/builtins/#url

You have a query string when you do GET request.
The form is sending a POST request, with the data in the body of the request.

'project': post.ProjectName, 'initial password': 
post.InitialPassword,'userType': post.UserType, 'contact': post.Contact, 
'businessType': post.BusinessType, 'company': post.Company,})

Re: Reverse for 'reg/{{post.pk}}/' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

[ludovic coues]

Have you done the django tutorial ? It help a lot when starting with django.

Your problem come from site1/urls.py . `include(admin.site.urls)` work
because you import admin. `include(site1.reg.urls)` cannot work
because site1 is not defined.

Also, the djangogirls tutorial [1] have a great chapter about form.

It should work better this way:

the url template tag take a route name, not an url as it first argument.
