Question

我与django用户模型建立了外键关系，正向查找工作正常，但是当我尝试向后移动时抛出此错误：

'QuerySet'对象没有属性'urlpost_set'

我也试过相关的名字！另请注意，Catagory到PostUrl和PostUrl到Catagory的工作正常！

我的models.py:

from django.db import models

from django.contrib.auth.models import User


# Create your models here.
class Catagory(models.Model):
    title = models.CharField(max_length=15, unique=True)
    created = models.DateField(auto_now_add=True)
    updated = models.DateField(auto_now=True)

    def __str__(self):
        return self.title

    class Meta:
        verbose_name_plural = 'catagory'


class UrlPost(models.Model):
    STATUS_CHOICES = (
        ('public', 'Public'),
        ('private', 'Private'),
    )
    profile = models.ForeignKey(User, related_name='user_post', on_delete=models.CASCADE)
    catagory = models.ForeignKey(Catagory, on_delete=models.CASCADE)
    title = models.CharField(max_length=200)
    slug = models.SlugField(unique=True)
    url = models.URLField()
    status = models.CharField(max_length=10, choices=STATUS_CHOICES, default='public')
    note = models.TextField(blank=True)
    created = models.DateField(auto_now_add=True)
    updated = models.DateField(auto_now=True)

    class Meta:
        ordering = ['-created']
        verbose_name_plural = 'url Post'

    def __str__(self):
        return self.title

Answer 1

您在定义related_name='user_post'模型与ForeignKey之间的User关系时设置了UrlPost。

您必须在查询集中使用.user_post.all()而不是.urlpost_set.all()。

Django用户模型，向后查找不起作用
