I tried passing a context variable as the url_name parameter like so:

{{{
{% url 'url' %}
}}}

Django raises a NoReverseMatch exception - Reverse for 'url' not found.
'url' is not a valid view function or pattern name.

When left unquoted like so:

{{{
{% url url %}
}}}

PyCharm gives me a warning (View names should be in quotes since Django
1.5 and should have no quotes before 1.5) despite Django apparently
accepting this and resolving to the correct URI.

Using Django 5.0.7

Comment:

Hi Petr, in the
[https://docs.djangoproject.com/en/5.0/ref/templates/builtins/#url
documentation for url], there is a warning:

> Don’t forget to put quotes around the URL pattern name, otherwise the
value will be interpreted as a context variable!

In this case, you want it to be treated as a context variable and so not
adding quotes is correct and adding them treats it as a view name.
This is working as expected to me and the behaviour is documented. Please
feel free to give feedback to PyCharm 👍
