title: Intermediate Django 2.0 admin action page not displaying
body: <p>I have created an update custom admin action and want to ask for update confirmation by going to a new page before the update action is finalised.</p>
  
  <p>Below is the code for various files:
  admin.py`</p>
  
  <pre><code>class ProfileHolderAdmin(admin.ModelAdmin):
      list_display = [field.attname for field in ProfileHolder._meta.fields]
      actions = ['update_verified']
  
      def update_verified(self, request, querySet):
          users_verified=querySet.update(verified='y')
          views.update_confirmation(request)
          self.message_user(request,"No. of users verified = %s" %str(users_verified))
  
      update_verified.short_description = "Mark selected users as verified"
  
  admin.site.register(ProfileHolder, ProfileHolderAdmin)`
  </code></pre>
  
  <p>Code in views.py:</p>
  
  <pre><code> def update_confirmation(request):
            return render(request,'Profile/confirm_update.html', context=None)
  </code></pre>
  
  <p>Code in confirm_update.html:</p>
  
  <pre><code> &lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Confirm Update&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
      &lt;form action="admin.py" method="post"&gt;
          &lt;p&gt;
              Are you sure you want to update the verification status of selected users?
          &lt;/p&gt;
          &lt;input type="hidden" name="action" value="update_status" /&gt;
          &lt;input type="submit" name="apply" value="Update status"/&gt;
      &lt;/form&gt;
  
  
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The path to the html file is:
  website_name\Profile\templates\Profile\confirm_update.html</p>
  
  <p>Profile is the name of my app and website_name is the directory name.</p>
  
  <p>When I carry out the update function, the status is being correctly updated but the intermediate update page is not showing.
  Please help.</p>
