Error NoReverseMatch at my url Reverse for my url name with arguments and keyword arguments not found n pattern s tried

0 votes

I have some code and when it executes, it throws a NoReverseMatch, saying:

NoReverseMatch at /my_url/ Reverse for 'my_url_name' with arguments '()' and keyword arguments '{}' not found. n pattern(s) tried: []

What does this mean, and what can I do about it?

Hello @kartik,

The NoReverseMatch error is saying that Django cannot find a matching url pattern for the url you've provided in any of your installed app's urls.

The NoReverseMatch exception is raised by django.core.urlresolvers when a matching URL in your URLconf cannot be identified based on the parameters supplied.

To start debugging it, you need to start by disecting the error message given to you.

  • NoReverseMatch at /my_url/

    This is the url that is currently being rendered, it is this url that your application is currently trying to access but it contains a url that cannot be matched

  • Reverse for 'my_url_name'

    This is the name of the url that it cannot find

  • with arguments '()' and

    These are the non-keyword arguments its providing to the url

  • keyword arguments '{}' not found.

    These are the keyword arguments its providing to the url

  • n pattern(s) tried: []

    These are the patterns that it was able to find in your urls.py files that it tried to match against

Hope it helps!!
Thank You!!
