When i make a post and hit the "PUBLISH BUTTON" is shows a "Blog" Object is not-CodePudding

I have tried many ways using filter, since get tried to get a single object but it still does work. When i make a post from my admin section everything works fine but when making the post from my front end using a form it creates the posts then shows me object is not iterable "NOTE: the posts get created perfect well" but i get the iterable error and also slug does not auto populate in the frontend automatically as it does in the backend admin section. Any help would be greatly usefull and make my work faster. let me show some of my code

views.py

#this is for allowing user to create a new post from the frontend

    if request.method == "POST":
        form = BlogPostForm(request.POST, request.FILES)

            form = form.save(commit=False)
            form.creator = request.user
            form.save()
            messages.success(request, f'Hi, Your Post have been sent for review and would be live soon!')
    else:
        form = BlogPostForm()

    context = {
        "form": form
    }
    return render(request, 'blog/AddPost.html', context)

CodePudding user response：

It would be helpful to see your template code, but here are a few issues I see.

First, your blogpost view. When you do a POST request, after you save the form and set the success message, redirect to the BlogDetail view. The way you have coded it, after saving the form it will again render the blogpost view, this time with the form containing the request POST data. Look up redirect here.

Second, in your BlogList view, you are calling .values() on your posts queryset. Without seeing your template code, I cant tell if this is intentional, but make sure you know what values() returns from a queryset. You might not want to use it.

Third, your BlogDetail view does not return anything, you need to return a HttpResponse using for example render like your other views.

And just as a final note, its common convention to name function based views in lower case, with _ as space. CamelCase is reserved for class based views.
