title: KeyError: 'user_id'
body: <p>I wanna put dictionary data to the model(User) .I wrote like</p>
  
  <pre><code> for row_number, row_data in dict_data.items():
              user1 = User.objects.filter(corporation_id=row_data['corporation_id'])
              if user1:       
                 user1.update(user_id=dict_data['user_id'])
  </code></pre>
  
  <p><code>dict_data</code> is dictionary type like</p>
  
  <pre><code>{'00010': OrderedDict([('corporation_id', '00001aB3D4'), ('user_id', '11111'), ('name', 'Tom'), ('age', '20')])}
  </code></pre>
  
  <p>I wanna put <code>dict_data</code> data's <code>user_id</code> to <code>user_id</code> column of <code>User</code>model. Definitely, <code>dict_data</code> has <code>'user_id'</code>, but I really cannot understand why this error happens.How can I fix this?</p>
