Django Query Error: How Do I Properly Query My Total Likes To Show In The Home Screen?

Can anyone advise on how to query the `total_likes of a post to be shown in my HTML, I tried, but was given this error: Page not found (404) No BlogPost matches the given query. T

Solution 1:

The exception: Page not found (404) No BlogPost matches the given query. is being raised by get_object_or_404 as it does exactly what the name says. If the BlogPost with the supplied slug in any of the views doesn't exist in the database, Django will raise an Http404 exception as you're witnessing.

Now, since we don't know the structure of your BlogPost model, I can't really tell you where to change, all I can tell you is you need to make sure, the slug is a unique field on each BlogPost instance, othwerwise your code is working as one would expect.

EDIT

I had not seen the BlogPost model, my bad, but the information is still relavant a BlogPost with such a slug does not exist. So do a manual check, see what the slug arrives in the view(s) as, and then check manually either in DB or in your shell.
