Question

我目前正在尝试使用Django构建博客。我现在已经面临这个错误几个小时了。我不太确定这是否与目录有关，但是当我尝试在admin.py文件中注册我的模型时会发生错误。

from django.contrib import admin
from .models import Post

# Register models
admin.site.register(Post)

目录如下：

blog
   models
        Post
        Category
   admin.py
settings
static
templates

发表：

from django.db import models
from django.utils import timezone


class Post(models.Model):
    # Auto-generated ID
    id = models.AutoField(primary_key=True)

    # Title
    title = models.CharField(max_length=100)

    # Slug
    slug = models.SlugField(max_length=100)

    # Content
    body = models.TextField()

    # Timestamps
    created_on = models.DateField(auto_now_add=True)
    published_on = models.DateTimeField(blank=True, null=True)

    # Category
    category = models.ForeignKey('.Category', on_delete=models.DO_NOTHING)

    # Author
    author = models.ForeignKey('auth.User', on_delete=models.DO_NOTHING)

    # Publish post
    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title

类别：

from django.db import models


class Category(models.Model):
    # Auto-generated ID
    id = models.AutoField(primary_key=True)

    # Title
    title = models.CharField(max_length=100)

    # Slug
    slug = models.SlugField(max_length=100)

    # Timestamps
    created_on = models.DateField(auto_now_add=True)

每当我评论注册行时，一切正常。

Answer 1

而不是从.models导入Post＆＃34;你应该写一下#m;来自.models.Post import Post＆＃34;。

首先＆＃34;发布＆＃34;是一个模块名（文件名），第二个是类名。

Django模块对象不可迭代
