title: access data ForeignKey django reverse way
body: <p>I have 2 models</p>
  <pre><code>class Book(models.Model):
    STATUS_CHOICES = (
        ('draft', 'Draft'),
        ('published', 'Publish')
      )
    name = models.CharField(max_length= 500)
    status = models.CharField(max_length = 10, 
                              choices = STATUS_CHOICES, 
                              default = 'draft')
  
  class Author (models.Model):
    name = models.CharField(max_length)
    book = models.ForeignKey(Book, on_delete=models.CASCADE)
  </code></pre>
  <p>now i want to implement query on books table and get it Author also, I don't want to apply query on author and myquery should be like that</p>
  <pre><code>select * from book left join ON book.id = author.book_id where book.status = 'published'
  </code></pre>
