Get current post's category

So as the title says, i need to get the current post's category to use it in a "related posts" section, more precisely what to put in cat_posts = Post.objects.filter(Category=????) (don't mind the comments variable since i removed part of my PostView from this post)

here's my code

views.py

def PostView(request, slug):
template_name = 'post-page.html'
post = get_object_or_404(Post, slug=slug)
comments = post.comments.filter(active=True)

cat_posts = Post.objects.filter(Category=Post.Category)
cat_posts = cat_posts.order_by('-Date')[:3}

return render(request, template_name, {'post': post,
                                       'cat_posts':cat_posts})

models.py

class Category(models.Model):
name = models.CharField(max_length=100)

def __str__(self):
    return str(self.name)



class Post(models.Model):
title = models.CharField(max_length=120)
Category = models.CharField(max_length=120, default='None')
Thumbnail = models.ImageField(null=True, blank=True, upload_to="images/")
Text = RichTextField(blank=False, null=True)
slug = models.SlugField(max_length=200, unique=True)
author = models.ForeignKey(User, on_delete=models.CASCADE)
Overview = models.CharField(max_length=400)
Date = models.DateTimeField(auto_now_add=True)
main_story = models.BooleanField(default=False)


def __str__(self):
    return str(self.title)

def get_absolute_url(self):
    # return reverse('about', args=(str(self.id)))
    return reverse('home')

You can obtain this with the post.Category (so the post *object, not the Post class):

def PostView(request, slug):
    template_name = 'post-page.html'
    post = get_object_or_404(Post, slug=slug)
    comments = post.comments.filter(active=True)
    cat_posts = Post.objects.filter(
        Category=post.Category
    ).order_by('-Date')[:3]
    return render(
        request,
        template_name,
        {'post': post, 'cat_posts':cat_posts}
    )

It is however better to work with a ForeignKey [Django-doc] to the Category than a CharField: if you later change the name of the category, then your posts are no longer pointing to a valid category.

Note: normally the name of the fields in a Django model are written in snake_case, not PerlCase, so it should be: category instead of Category.
