POST相关字段Django rest框架 [英] POST related Fields Django rest Framework

问题描述

django新的。我想要做的是POSTING一个具有OneToOneField属性的模型。你如何POST？

Models.py

 code>文章（models.Model）：
 name = models.CharField（max_length = 50）
 description = models.TextField（max_length = 200）
 
特征model.Model）：
 article = models.OneToOneField（Article，on_delete = models.CASCADE，primary_key = True）
 other = models.FloatField（）
 another = models.IntegerField（）
  

Serializer.py

pre> class ArticleSerializer（serializers.ModelSerializer）：
class Meta：
model = article
field ='__ all__'
class CharacteristicSerializer serializer.ModelSerializer）：
article = serializers.StringRelatedField（）
class Meta：
model = Characteristic
field ='__ all__'


Views.py POST方法（基于API）

  def post（self，request，format = None）：
 serializer = CharacteristicSerializer（data = request.data）
如果serializer.is_valid（）：
 serializer.save（）
返回响应（serializer.data，status = status.HTTP_201_CREATED）
返回响应（serializer.errors，status = status.HTTP_400_BAD_REQUEST）
  

如果我尝试POST这样的东西：

（some_url ...）/ features / other = 4.4 another = 4 post = 1

我收到下一个错误：

django.db。 utils.IntegrityError：（1048，Columnpost_id不能为
null）

想法是接收id的模型文章，然后保存模型特征。

任何想法？

解决方案

最后我能够解决。只有关于字典。

方法POST

  def post（self，request，format = None）：
 serializer = CharacteristicsSerializer（data = request.data）
如果serializer.is_valid（）：
 tmp = self.get_article （pk = int（self.request.data ['article']））
 serializer.save（article = tmp）
返回响应（serializer.data，status = status.HTTP_201_CREATED）
返回响应（serializer.errors，status = status.HTTP_400_BAD_REQUEST）
  

现在正在工作，如果有是另一个更好的方式来做，有人想分享它我会感激

new at django. What I am trying to do is POSTING a model which has a OneToOneField property. How do you POST that?

Models.py

Article(models.Model):
    name=models.CharField(max_length=50)
    description=models.TextField(max_length=200)

Characteristic(models.Model):
   article=models.OneToOneField(Article,on_delete=models.CASCADE,primary_key=True)
   other=models.FloatField()
   another=models.IntegerField()

Serializer.py

class ArticleSerializer(serializers.ModelSerializer):
    class Meta:
        model=Article
        field='__all__'
class CharacteristicSerializer(serializers.ModelSerializer):
    article=serializers.StringRelatedField()
    class Meta:
        model=Characteristic
        field='__all__'

Views.py POST METHOD (API Based)

def  post(self, request,format=None):
    serializer=CharacteristicSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data,status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

If I try to POST with something like this:

(some_url...)/characteristics/ other=4.4 another=4 post=1

I get the next error:

django.db.utils.IntegrityError: (1048, "Column 'post_id' cannot be null")

The idea is to receive the id of the model Article and then save the model Characteristic.

Any ideas?

解决方案

Finally I was able to solve it. It is only about dictionaries.

Method POST

def  post(self,request,format=None):
    serializer=CharacteristicsSerializer(data=request.data)
    if serializer.is_valid():
        tmp=self.get_article(pk=int(self.request.data['article']))
        serializer.save(article=tmp)
        return Response(serializer.data,status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

For now that is working, if there is another better way to do it and someone want to share it I'll be thankful
