title: In Django admin, how can I hide Save and Continue and Save and Add Another buttons on a model admin?
body: <p>I have a workflow for a model in the Django admin that is very similar to the users' workflow. First, I have a form with basic fields and then, a second form with the rest of the data.</p>
  <p>It's the same workflow as auth.user</p>
  <p>I need to remove &quot;save and continue&quot; and &quot;save and add another&quot; buttons to prevent the user breakoing the workflow.</p>
  <p>I have tried to add it as extra_context:</p>
  <pre><code>extra_context = {
    'show_save_and_add_another': False,
    'show_save_and_continue': False
  }
  </code></pre>
  <p>and pass it through ModelAdmin.add_view or ModelAdmin.change_view but it doesn't work.</p>
  <p>This is only for one model, so I don't want to remove from submit_line.html</p>
  <p>Any clue or alternative way?</p>
  <p>Thanks in advance</p>
