Python 导入错误：无法导入名称'；评论'；

我得到了一个错误：

ImportError:无法导入名称“Comment”

当我尝试在admin.py目录中运行以下代码时：

from django.contrib import admin
from .models import Post, Comment
# Register your models here.

admin.site.register(Post)
admin.site.register(Comment)

我试图通过查看文档来解决这个问题，但什么也找不到

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

# Create your models here.

class Post(models.Model):
    author = models.ForeignKey('auth.User', models.CASCADE)
    title = models.CharField(max_length=288)
    text = models.TextField()
    create_date = models.DateTimeField(default=timezone.now())
    published_date = models.DateTimeField(blank=True,null=True)

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

        def approve_comments(self):
            return self.comments.filter(approve_comments=True)

        def get_absolute_url(self):
            return reverse("post_detail",kwargs={'pk':self.pk})

        def __str__(self):
            return self.title



    class Comment(models.Model):
        post = models.ForeignKey('blog.Post', models.CASCADE, related_name='comments')
        author = models.CharField(max_length=200)
        text = models.TextField()
        create_date = models.DateTimeField(default=timezone.now())
        approved_comment = models.BooleanField(default=False)

        def approve(self):
            self.approved_comment = True
            self.save()

        def get_absolute_url(self):
            return reverse('post_list')

        def __str__(self):
            return self.text

更改它，使类注释位于类帖子之外： 像这样：

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

# Create your models here.

class Post(models.Model):
    author = models.ForeignKey('auth.User', models.CASCADE)
    title = models.CharField(max_length=288)
    text = models.TextField()
    create_date = models.DateTimeField(default=timezone.now())
    published_date = models.DateTimeField(blank=True,null=True)

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

        def approve_comments(self):
            return self.comments.filter(approve_comments=True)

        def get_absolute_url(self):
            return reverse("post_detail",kwargs={'pk':self.pk})

        def __str__(self):
            return self.title

    def approve(self):
        self.approved_comment = True
        self.save()

    def get_absolute_url(self):

你能给我们看看你的模型吗？里面有模型的编辑过的帖子。但是你可以导入帖子吗？为什么在类Post中有类注释？@DavidHexynator在实际代码中对注释类的缩进与粘贴在此处的缩进相同吗？您能给我们看一下您的模型吗？编辑后的文章中有模型。但是您可以导入Post吗？为什么在类Post中有类注释？@DavidHexynator在实际代码中对注释类的缩进是否与粘贴在此处的缩进相同？
