It means that there is no line in urls.py of the main application with the name as 'display_laptop'. Probably you are confused with the action and name. Action should be a callable and should be imported in urls.py file. Name is the name of the route and it appears within quote (normally).

Typically a url is: [url_pattern, callable, {additional parameters or empty}, name='display_laptop']

if you are going to write a function called display_laptop, import it into the urls.py and in the above url, replace callable with display_laptop (no quote); that is:

from .... import display_laptop

urlpatterns = [ [.....], [url_pattern, display_laptop,{..}, name='display_laptop'],....]

Cheers.
