首先,我的模型:
class Director(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
class Movie(models.Model):
title = models.CharField(max_length=150, unique=True)
director = models.ForeignKey(Director, related_name="movies")
我想发布json文件来创建导演,带电影的导演(一次性)或电影。
所以,这是我的序列化程序:
class MovieSerializer(serializers.ModelSerializer):
id = serializers.IntegerField(read_only=True)
url = HyperlinkedIdentityField(view_name='movie')
class Meta:
model = Movie
exclude = ('director', ) # edit (solution) this line is the problem. It does not only affect the representation... Just remove that and it's OK
class DirectorSerializer(serializers.ModelSerializer):
movies = MovieSerializer(many=True)
class Meta:
model = Director
fields = '__all__'
def create(self, validated_data):
movies = validated_data.pop('movies')
director = self.Meta.model.objects.create(**validated_data)
for movie in movies:
Movie.objects.create(director=director, **movie)
return director
所以,(感谢httpie),创建一个新导演:
{
"first_name": "Christopher",
"last_name": "Nolan",
"movies": []
}
工作正常。 用电影创建新导演:
{
"first_name": "Luc",
"last_name": "Besson",
"movies": [
{
"title": "Le Grand Bleu"
}
]
}
也有效。 但我无法添加新电影 即创建新电影。 JSON:
{
"title": "Interstellar",
"director": 1
}
导演的id = 1 => C. Nolan; - )
我想我错过了什么,所以如果有人可以帮助我,建议我或其他什么?
谢谢,问候
我必须POST的JSON文件才能将“Interstellar”电影添加到Nolan的电影中(id_director = 1)?
答案 0 :(得分:3)
您无法在此处添加新电影,因为您已排除MovieSerializer中的director
字段。但导演领域是电影模型所必需的。删除排除应该工作
