My Code is below, if I pass posts data via context, than i get "Reverse for 'user_profil' not found. 'user_profil' is not a valid view function or pattern name." without any "context", i get no error. I have read lots of the comments but no one points out this problem!
If someone can help me , I will be pleasure!
view function:
def user_profil(request, username):
posts = postList.objects.all().filter(author__username__icontains=username)
context = {}
context['posts'] = posts
return render(request, 'profile.html', context=context)
Url_patterns:
urlpatterns = [
path('', postlist_view.home, name='home'),

This line of code seems to be the problem:
<a href="{% url 'user_profil'%}"><h3>{{post.author}}</h3></a>
From the urlpatterns you provided, there doesn't seem to be a url with the name 'user_profil'. Instead, you might want to use the same href as the other anchor tag as shown bellow:
<a href="{% url 'page_of_user' username=post.author %}"><h3>{{post.author}}</h3></a>
Edit: Thanks to Alasdair for pointing out the typo in this line:
path('profil/<usernaname>/', postlist_view.user_profil, name='page_of_user'),
You need to match the url parameter to the one used in the url tag in the HTML, so you should to change it to:
path('profil/<username>/', postlist_view.user_profil, name='page_of_user'),
