what is NoReverseMatch in django?

NoReverseMatch is a type of error in Django that occurs when the reverse function is unable to find a matching URL pattern for the given view name and optional parameters. It typically arises in situations where the URL configuration does not match the view or when the parameters provided do not correspond to the URL pattern. To troubleshoot this error, steps include checking the view name and URL pattern alignment, ensuring that the URL configuration is correctly defined in the urls.py file, and confirming that any optional parameters are correctly passed to the reverse function.
