deleting a post in django-CodePudding

hi ive read some of similar posts but couldn't find same problem. i wrote a code to delete post and when i press delete it shows 404 error but when back to home post is still there views:

def delete_music_view(request,music_id):
    # view for deleting music
    my_object = add_music.objects.get(id=music_id)
    if request.method == 'POST':
        my_object.delete()
        return redirect('pages:home')   
    context = {'my_object':my_object}

    return render(request,'pages/delete_music.html',context)

url:

urlpatterns = [
    path('',views.home,name='home'),
    path('add_music/',views.add_music_view,name='add_music'),
    path('musics/<int:music_id>',views.musics_view,name='music_page'),
    path('musics/<int:music_id>/delete',views.delete_music_view,name='delete_music'),
]

template:

{% extends 'pages/base.html' %}

{% block content %}
<form action="." method='POST'>
    {% csrf_token %}
    <p><input type="submit" name="delete" value="yes"><a href="../../">cancel</a></p>
</form>
{% endblock %}

can u pls tell me whats wrong?

CodePudding user response：

Since the delete_music_view method is going to handle the POST request there's no need to use the form attribute action. You have:

<form action="." method='POST'>
    {% csrf_token %}
    <p><input type="submit" name="delete" value="yes"><a href="../../">cancel</a></p>
</form>

Remove the action from your form and have this instead:

<form method='POST'>  # Removing the action attribute
    {% csrf_token %}
    <p><input type="submit" name="delete" value="yes"><a href="../../">cancel</a></p>
</form>

That should work.

Also, note that <a href="../../">cancel</a> will show you another 404 error if you don't set a recognizable url for django to handle.

I hope this answer helps.
