  试试这个片段，

  views.py

  class MovieViewSet(viewsets.ModelViewSet):
      queryset = Movie.objects.all()
      serializer_class = MovieSerializer
      permission_classes = [IsAuthenticated]
      authentication_classes = [TokenAuthentication]
  

  models.py

  class Director(models.Model):
      name = models.CharField(max_length=100)
  
      # extra fields
      def __str__(self):
          return self.name
  
  
  class Genre(models.Model):
      name = models.CharField(max_length=100)
      # extra fields
  
  
  class Movie(models.Model):
      popularity = models.DecimalField(max_digits=3, decimal_places=1)
      imdb_score = models.DecimalField(max_digits=2, decimal_places=1)
      name = models.CharField(max_length=200)
      director = models.ForeignKey(Director)
      genre = models.ManyToManyField(Genre)
  
      def __str__(self):
          return self.name
  

  serializer.py

  class MovieSerializer(serializers.ModelSerializer):
      name = serializers.StringRelatedField()
      director = serializers.StringRelatedField()
  
      class Meta:
          model = Movie
          fields = '__all__'
          depth = 1
  

  Expected Output

  [
      {
          "id": 2,
          "name": "Thor",
          "director": "director_1",
          "popularity": "7.0",
          "imdb_score": "5.0",
          "genre": [
              {
                  "id": 3,
                  "name": "Action"
              }
          ]
      }
  ]
  

  如果有效，请告诉我 .
