问题描述
我的Django项目中有一个帖子和一个类别应用程序。我具有用户身份验证,用户可以创建类别和帖子。我的想法和帮助将不胜感激。我希望用户只能引用自己的类别,而不能在其他人自己的类别中创建帖子。就是说,如果用户创建了一个以上的类别,则他应该能够从其创建的类别的列表中进行选择,而不会看到其他人拥有的。
I have a post and a category app in my django project. I have user authentication and users can create categories as well as posts. I am at a point where I am out of ideas and help would be appreciated. I want users to be able to reference only their own category and create posts in their categories not in another persons own. That is if a user creates more that one category he should be able to select from the list of his created category and not see another persons own.
类别模型
class Category(models.Model):
name = models.CharField(max_length = 120)
slug = models.SlugField(unique= True)
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
发布模型
class Post(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1,related_name='posts_created') #blank=True, null=True)
title = models.CharField(max_length = 120)
slug = models.SlugField(unique= True)
category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='category_created', null= True)
附加代码将根据要求立即提供。谢谢

后应用程序中的View.py
def create(request):
if not request.user.is_authenticated():
messages.error(request, "Kindly confirm Your mail")
#or raise Http404
form = PostForm(request.POST or None, request.FILES or None)
user = request.user
categories = Category.objects.filter(category_created__user=user).distinct()
if form.is_valid():
instance = form.save(commit=False)
instance.user = request.user
instance.save()
create_action(request.user, 'Posts', instance)
messages.success(request, "Post created")
return HttpResponseRedirect(instance.get_absolute_url())
context = {
"form": form,
"categories": categories,
}
template = 'create.html'
return render(request,template,context)
表格
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = [
"title",
"content",
"category",
]
html
{% if form %}
<form method="POST" action="" enctype="multipart/form-data">{% csrf_token %}
{{ form|crispy|safe }}
<input type="submit" name="submit" value="Publish">
</form>
{% endif %}
推荐答案
想要列出某个视图中用户已添加的所有类别。
You probably want to list all the Categories to which a user has contributed on some view.
您可以通过以下方式获取用户已添加的所有类别:
You can get all the Categories to which a user contributed in the following way:
user = request.user # assuming you're in a view
categories = Category.objects.filter(post__user=user).distinct()
