title: Django Admin Action using intermediate page
body: <p>I have a model with a lot of fields. I only have a few fields I that I want to be required. So instead of the change list super long, I want to have a short change list then have admin actions that can give predefined subsets of the fields.</p>
  
  <p>The initial action takes me to the correct page but when I submit the form it returns me to whatever page I designate, but doesn't update the fields. I am okay with tearing this down starting over again if needed. I think what I really need to know, what do I put in the action="" portion of the html to have the recursion work properly?</p>
  
  <p>I am using django 1.7. I have to obfuscate a lot of my fields as a cya thing since I am working in a heavily information secure field.</p>
  
  <p>Here is my admin.py</p>
