title: Django get data from multiple tables
body: <p>I want to fetch and display details(name_project, user_name) from both tables Project and User1</p>
  
  <p>models.py</p>
  
  <pre><code>class Project(models.Model):
      name_project = models.CharField(max_length=50)
      leader = models.ForeignKey('User1', default='')
      category_project = models.CharField(max_length=50)
  class User1(models.Model):
      user_name = models.CharField(max_length=30)
      mail = models.EmailField(max_length=50)
      password = models.CharField(max_length=50)
  </code></pre>
  
  <p>views.py</p>
  
  <pre><code>def list_project(request):
  queryset = Project.objects.raw(
      'SELECT scrum_rest_project.id, scrum_rest_project.name_project, scrum_rest_user1.user_name FROM scrum_rest_user1,scrum_rest_project WHERE scrum_rest_user1.id = scrum_rest_project.leader_id')
  queryset = serializers.serialize('json', queryset)
  return HttpResponse(queryset, content_type="application/json")
  </code></pre>
  
  <p>but it displays only data from Project table in the json file, I want to display data from User1 table also</p>
