Setting base_url is not used

[pacnos]

I tried to change the used bootstrap4 version. So I added to following dict to the settings.py:

BOOTSTRAP4 = { # The Bootstrap base URL 'base_url': '//maxcdn.bootstrapcdn.com/bootstrap/4.1.3/', }

But the tag {% bootstrap_css %} still includes version 4.0.0:

<link crossorigin="anonymous" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" rel="stylesheet">

Do you have a css_url defined in settings?

[pacnos]

No, the css_url is not set in my settings file. As I understod the documentation, if I didn't set a css_url the url will be build from the base_url. Is this correct?

[dyve]

Yes, that's why I asked. I'll investigate.

Could you try if it works if you explicitly setcss_url to None? I think the problem is that there is a default value for css_url.

I've confirmed this is due to a change in the defaults. The CDN version of BS4 used to be provided by a base_url. In order to accommodate crossorigin/integrity, the defaults are now in a css_url and javascript_url.

This will require a fix, and the fix may require some discussion.

Workaround for now: explicitly set css_url to None in your settings, and your base_url will work.

Suggestion (thanks @jieter). Let's get rid of base_url as a magic way to include stuff, and just have an explicit javascript_url and css_url that default to the CDN. This would be a breaking change.

@pacnos Would you that be an acceptable direction for you?

[pacnos]

@dyve Sounds like a good and simple solution ....
