Django的REST框架HTML表单的POST给错误消息此字段提交

Question

我的models.py后需要的是

class Genre(models.Model): 
    genre = models.CharField(max_length=200) 
    def __str__(self): 
     return self.genre 


class Movies(models.Model): 
    popularity=models.DecimalField(max_digits=5, decimal_places=2) 
    director = models.CharField(max_length=200) 
    genre = models.ManyToManyField(Genre, blank=True, null=True) 
    score= models.DecimalField(max_digits=5, decimal_places=2) 
    name = models.CharField(max_length=200) 
    def __str__(self): 
     return self.name 

这是我的串行和视图集中

# Serializers define the API representation. 
class MoviesSerializer(serializers.ModelSerializer): 
    #genre = serializers.StringRelatedField(many=True) 
    genre = serializers.SlugRelatedField(queryset=Genre.objects.all(),many=True,slug_field='genre') 
    class Meta: 
     model = Movies 
     fields = ('popularity', 'director', 'genre', 'score','name') 

# ViewSets define the view behavior. 
class MovieViewSet(viewsets.ModelViewSet): 
    queryset = Movies.objects.all() 
    serializer_class = MoviesSerializer 

# Routers provide an easy way of automatically determining the URL conf. 
router = routers.DefaultRouter() 
router.register(r'movies', MovieViewSet) 

我能看到HTML POST表单登录为Superuser。但在提交HTML POST表单时收到错误消息This field is required。代码中的错误是什么？感谢提前帮助。

您应该使用SlugRelatedField代替StringRelatedField的了点。
