我在 django rest 框架中收到完整性错误

问题描述

我是 Django 的初学者。我想添加一些帖子和评论，但出现完整性错误。 没有评论模型，它以前可以工作，但不能一起工作。我已经删除了我的数据库并进行了迁移，然后再次迁移。

后期模特

from django.db import models
from django.conf import settings
# from django.contrib.auth import get_user_model


# User = get_user_model()

# Create your models here.
class Post(models.Model):
    user = models.ForeignKey(
        #to=User,to=settings.AUTH_USER_MODEL,on_delete=models.CASCADE,related_name='posts',null=True
    )
    content = models.CharField(
        max_length=150,blank=False
    )
    created = models.DateTimeField(
        auto_now=True
    )
    liked_by = models.ManyToManyField(
         #to=User,related_name='liked_posts',blank=True
    ) 

后序列化器

 from rest_framework import serializers
from .models import Post
from ..comment.serializers import CommentSerializer


class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        comments = CommentSerializer(source='comments.content')
        fields = [
            'id','user','content','comments','created','liked_by',]

comment.models

from django.db import models
from django.conf import settings
from apps.post.models import Post


# Create your models here.
class Comment(models.Model):
    user = models.ForeignKey(to=settings.AUTH_USER_MODEL,related_name='comment',null=True)
    post = models.ForeignKey(to=Post,on_delete=models.SET_NULL,null=True)
    content = models.CharField(max_length=150)
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return f'Comment by: {self.user}'

注释序列化器

from rest_framework import serializers
from .models import Comment


class CommentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Comment
        fields = ['id','post','created']
