使用django rest框架发布时发生AssertionError

使用django rest框架发布时发生AssertionError 发生错误之前的过程如下

我设置了url模式、视图和序列化器类

看法

序列化程序.py

from django.contrib.auth import get_user_model
from rest_framework import serializers
from rest_framework.serializers import ModelSerializer
from instagram.models import Post

class AuthorSerializer(serializers.ModelSerializer):
   class Meta:
      model = get_user_model()
      fields = ['username','email']


class PostSerializer(ModelSerializer):
   author = AuthorSerializer()
   
   class Meta:
      model = Post
      fields = [
         'pk',
         'author',
         'message',
         'created_at',
         'updated_at',
         'is_public',

      ]

感谢您让我知道如何修复它

它假定保存您在

后序列化程序中提供的
作者
详细信息。您可以有自己的create（）方法，如下所示-

def create(self, validate_data):
    data = validated_data
    author = data.get('author')
    # You can use author details here
    data.pop('author')
    return Post.objects.create(**data)
    

将序列化程序中的
read\u
设置为
AuthorSerializer（read\u only=True）
from django.contrib.auth import get_user_model
from rest_framework import serializers
from rest_framework.serializers import ModelSerializer
from instagram.models import Post

class AuthorSerializer(serializers.ModelSerializer):
   class Meta:
      model = get_user_model()
      fields = ['username','email']


class PostSerializer(ModelSerializer):
   author = AuthorSerializer()
   
   class Meta:
      model = Post
      fields = [
         'pk',
         'author',
         'message',
         'created_at',
         'updated_at',
         'is_public',

      ]

def create(self, validate_data):
    data = validated_data
    author = data.get('author')
    # You can use author details here
    data.pop('author')
    return Post.objects.create(**data)
