[Answer]-Why do I get 'invalid literal for int()' when running my query?

Without seeing your urls.py it’s hard to say for sure, but I’m guessing your URL pattern has something like:

url(r'^reviews/([\d]+)$', views.show_reviews),

when it needs to have something like:

url(r'^reviews/([\w]+)$', views.show_reviews),

or

url(r'^reviews/(.+)$', views.show_reviews),

Either that or your UserReview object’s name field is an int when it should be a string. Perhaps post more of the code?

I’m assuming name is a foreign key field and username is a string that comes from the URL pattern, which django is attempting to convert to a key (integer). Instead of comparing username directly to the foreign key, follow that foreign key using __ and check against the username there.

For example if name is a foreign key into Django’s built-in User model (django.contrib.auth.models.User) you’d do it like this:

latest_reviews = UserReview.objects.filter(name__username=username)
