[Django]-Django error – matching query does not exist

✅

your line raising the error is here:

comment = Comment.objects.get(pk=comment_id)

you try to access a non-existing comment.

from django.shortcuts import get_object_or_404

comment = get_object_or_404(Comment, pk=comment_id)

Instead of having an error on your server, your user will get a 404 meaning that he tries to access a non existing resource.

Ok up to here I suppose you are aware of this.

Some users (and I’m part of them) let tabs running for long time, if users are authorized to delete data, it may happens. A 404 error may be a better error to handle a deleted resource error than sending an email to the admin.

Other users go to addresses from their history, (same if data have been deleted since it may happens).

Maybe you have no Comments record with such primary key, then you should use this code:

try:
    comment = Comment.objects.get(pk=comment_id)
except Comment.DoesNotExist:
    comment = None

You can use this:

comment = Comment.objects.filter(pk=comment_id)

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return Comment.objects.get(pk=id)
    except Comment.DoesNotExist:
        return False

I think the problem is that there is some data that has been passed in your dev server that wouldn’t be migrated to your Production server.

The easiest thing to do will be to locate those dependencies on your production database and provide them

comment = Comment.objects.get(pk=comment_id) if Comment.objects.filter(pk=comment_id).exists() else None

Try this one

comment, created = Comment.objects.get_or_create(pk=comment_id)
