title: Django: access the model meta class value
body: <p>I have some model classes defined:</p>
  
  <pre><code>class ModelA(models.Model):
      class Meta:
          abstract = True
  
  class ModelB(ModelA):
      class Meta:
          abstract = False
  </code></pre>
  
  <p>So, now I have a class object, I want to check if it is abstract, is there any way to do this?</p>
  
  <p>For example, I want something like:</p>
  
  <pre><code>&gt;&gt;&gt; ModelA.abstract
  True
  &gt;&gt;&gt; ModelB.abstract
  False
  </code></pre>
