我如何限制在 Django 中的访问？

Question

我有一个应用程序，所有用户在注册后都可以发表文章，我怎样才能做到只有有权限的人才能发表文章（比如普通用户和版主/编辑，以及如何授予这些权利。下面是附加代码：

模型。py/blogapp

 class Post(models.Model):
        title = models.CharField(verbose_name=("Заголовок"), max_length=200)
        author = models.ForeignKey(User, on_delete=models.CASCADE)
        header_image = models.ImageField(verbose_name=("Заглавное Изображение"), null=True, blank=True, upload_to="images/" )
        body = RichTextField(verbose_name=("Тело Статьи"), blank=True, null=True)
        #body = models.TextField(blank=True, null=True)
        post_date = models.DateTimeField(auto_now_add=True)
        category = models.CharField(verbose_name=("Категория"), max_length=200)
        snippet = models.CharField(verbose_name=("Фрагмент Статьи"), max_length=200)
        likes = models.ManyToManyField(User, related_name='blog_post')
        updated_on = models.DateTimeField(auto_now= True)
        
    
        def total_likes(self):
            return self.likes.count()
    
    
        def __str__(self):
            return self.title + ' | ' + str(self.author)
    
        def get_absolute_url(self):
            return reverse('article_detail', args=[str(self.id)])

你好asd你可以像这样在你的配置文件模型中添加这样的标志

class Profile(models.Model):
    user = models.ForeignKey(User,on_delete=models.PROTECT)
    is_moderator = models.BooleanField(default=False)
    is_editor = models.BooleanField(default=False)#you can add many more as you want

您可以在模板或视图中像这样验证用户在 views.py

def check_user(request):
    moderator_profile = Profile(user_id=request.user.id,is_moderator=True)
    editor_profile = Profile(user_id=request.user.id,is_editor=True)
    if user_profile:
        return redirect('url_for_moderator')
    elif editor_profile:
        return redirect('url_for_editor')

或

您可以将数据传递给模板并为特定用户提供特定功能像这样

在你的 views.py

def get_post(request):
    user_profile = Profile.objects.filter(user=request.user.id)
    return render(request,"post.html",{"user_profile":user_profile})

和里面post.html

{% if user_profile.is_editor or user_profile.is_moderator %}
<button>Edit</button>
{% endif %}
