從Django中的外鍵關係檢索兩個表中的數據？

This is my models.py file 


from django.db import models 

    class Author(models.Model): 
     first_name = models.CharField(max_length=30) 
     last_name = models.CharField(max_length=40) 
     email = models.EmailField() 
     age=models.IntegerField() 

     class Meta: 
     db_table=u'Author Info' 

     def __unicode__(self): 
      return u"%d %s %s %s" % (self.pk, self.name, self.author.name, self.publisher_name) 

     def books(self): 
      return Book.objects.filter(author=self) 

    class Book(models.Model): 
     book_name=models.CharField(max_length=30) 
     publisher_name=models.CharField(max_length=40) 
     author=models.ForeignKey(Author) 

     class Meta: 
      db_table = u'Book Name' 

     def __unicode__(self): 
      return u'%d %s %s' % (self.pk, self.first_name, self.last_name)
