title: Django add into many-to-many field for each item in a queryset?
body: <p>Suppose I have the following model:</p>
  
  <pre><code>class User(models.Model):
      blogs = model.ManyToManyField(Blog)
  </code></pre>
  
  <p>What is the best way to add a blog to the field for multiple users e.g. I want to add an instance of Blog called blog to all users (i.e. <code>User.object.all()</code>). Do I have to iterate over each result individually or is there a way to do it all at once?</p>
  
  <p>Thanks.</p>
