title: How do I use the django-cms Python api to create a page?
body: <p>I'm trying to write a CMS content migration script that will create our pages for django-cms.  However even with the default install of Django-cms, Django-treebeard keeps raising exceptions and it's not clear to me why.</p>
  
  <p>For example, when this line is executed:</p>
  
  <pre><code>api.create_page(title="Hello world",
      language='en',
      parent=None)
  </code></pre>
  
  <p>My script always fails here (line 307-8) in mp_tree.py (v 4.1.0) from treebeard:</p>
  
  <pre><code>if newobj.pk:
      raise NodeAlreadySaved("Attempted to add a tree node that is "\
                  "already in the database")
  </code></pre>
  
  <p>Does anyone have a very simple example on how to use the cms.api.create_page() method?</p>
