How do I redirect back to user profile when a delete operation is complete

Using Django Using the ORM
1

Hello!

I have a problem that I cannot solve.

Background:

I’m developing a website with user authentication and profile pages. I have renderad all posts that a user have created on the users profil page. There is also options to update or delete a certain post. However, the delete option is not working properly. I know the cause of the error but I have not solution to it.

Before I attempt to explain the issue, I’ll share my codes.

View functions:

def profilepage(request, pk):
   user = Member.objects.get(id=pk)
   profilePageAdds = Room.objects.values("id", "title")

   context = {"profilePageAdds": profilePageAdds, "user": user}
   return render(request, "profile_app/profilepage.html", context)


def deleteRoom(request, pk):
   room = Room.objects.get(id=pk)
   room.delete()

   return redirect("profilepage_app:profilepage")


def updateRoom(request, pk):
   updateRoom = Room.objects.get(id=pk)
   if request.method == 'POST':
       updateRoom.title = request.POST.get('title')
       updateRoom.save()
       return redirect('profilepage_app:profilepage')

   context = {"updateRoom": updateRoom}
   return render(request, "profile_app/profilepage.html", context)

URL patterns:


app_name = "profilepage_app"

urlpatterns = [
  
   path("profil/<str:pk>/", views.profilepage, name="profilepage"),

   # Path for CRUD Ops

   path("profil/adds/delete/<int:pk>/",
        views.deleteRoom, name="deleteRoom"),
   path('post/<int:pk>/update/', views.updateRoom, name='updateRoom'),

HTML code:

<div class="m-1 d-flex flex-column">
       <table class="table table-striped">
           <thead>
               <tr>

                       My posts
                   </th>
               </tr>
           </thead>
           <tbody>
               {% for add in profilePageAdds %}
                   {% if request.user == user %}
                       <tr>

As you can see, I am quering the Member ID in the profilepage-function. In the profile page, when a certain post must be deleted, the error that I receive states:

error
error804×60 3.18 KB

error2

  • How can a user delete a certain post and return back to users profile page where only the existing post are displayed?
  • Can I somehow use the PK from the profilepage-function in the deleteRoom-function?
  • Do I use reverse() in my deleteRoom-function or what can I do?

The issue are these two lines:

(This line occurs twice in the code above.)

That url is defined as:

Which means reversing it requires an arg be passsed to it. See django.urls utility functions | Django documentation | Django for how to pass args to the reverse function.

It’s up to you to decide what the value is that you’re going to pass - or if that’s even the right url you want to reverse.
