i am trying to make site with django and want to categorize each post and a category list. in the category list every category name will be shown as a list and every category name will be linked to the posts according to their categories.

here is my models.py:

class Category(models.Model):
    name=models.CharField(max_length=1000,null=True)
    def __str__(self):
        return self.name    
class Post(models.Model):
    title=models.CharField(max_length=200,blank=True,null=True)
    author=models.ForeignKey(get_user_model(),on_delete=models.CASCADE,null=True)
    body=RichTextField(blank=True,null=True) 
    image=models.FileField(upload_to="mediaphoto")
    topImage=ImageSpecField(source='image',processors=[ResizeToFill(750,300)],format='PNG',options={'quality':60}) 
    date=models.DateField(default=datetime.now, blank=True)
    category = models.ForeignKey(Category,on_delete=models.CASCADE,verbose_name="Categories")      

    def __str__(self):
        return self.title
    def get_absolute_url(self):
        return reverse('post_detail',args={str(self.id)})

here is my views.py:

def Categorylist(request):

    categories = Category.objects.all()

    return render (request, 'category_list.html', {'categories': categories})

def CategoryDetail(request,pk):

    category = get_object_or_404(Category, pk=pk)

    return render(request, 'post_category.html', {'Category': category})

here is my urls.py:

urlpatterns = [
    path('post/<int:pk>/delete/',BlogappDeleteView.as_view(),name='post_delete'),
    path('post/<int:pk>/edit/',BlogappUpdateView.as_view(),name='post_edit'),
    path('post/new/', BlogappCreateview.as_view(),name='post_new'),
    path('post/<int:pk>/',BlogappPostView.as_view(),name='post_detail'), 
    path('post/<int:pk>/category', views.CategoryDetail, name='category'),
    path('search',views.Search,name='search'),
    path('',BlogappListView.as_view(),name='home'),

]

here is post_category.html

  <h3>{{ category.name }} Category</h3>
{% for c in category %}
<h2 class="card-title">{{post.title}}</h2>
    <p class="card-text">{{post.description|truncatechars:400|safe}}</p>
    <a href="{% url 'post_detail' post.pk %}" class="btn btn-primary">Read More &rarr;</a>

    Posted on {{post.date|safe}} by
    <a href="/">{{post.author}}</a>
in <a href="/">{{post.category}}</a>
  {% endfor %}

here is category_list.html:

{% for c in categories %}
<li>
  <a href="{% url 'category' post.pk %}">{{c.name}}</a>
</li>
{% endfor %}

main problem is that category list is not fetching any list from the Category name and when click on the category in a post below, it is not showing the posts related to this category. the category page is showing the category name post like physics category.

i think i messed up with the views.py query or in templates... will you help me on this please? it will be very much appreciated.
