CSS assets fail to load when using catch all or vanity url

[kjf]

My app has a user route at the end of my routes file to support vanity urls. E.g.

resources :users, only: :show, path: ""

meaning I can resolve: https://myapp.com/excid3

This seems to cause a problem with the madmin css files as they now get caught by my users route before they have a chance to resolve.

I'm seeing the following errors as a result:

ActiveRecord::RecordNotFound (can't find record with friendly id: "pagination"):
ActiveRecord::RecordNotFound (can't find record with friendly id: "sidebar"):
etc...

Is it possible to namespace the madmin assets to avoid this?

As a quick follow up. It seems this is caused by cloudfront which is configured as an asset host.

Looking at the CSS file that's served up by cloudfront I can see this:

@import url(https://d1lgo521xfi61.cloudfront.net/../trix.css);
@import url(https://d1lgo521xfi61.cloudfront.net/actiontext.css);
@import url(https://d1lgo521xfi61.cloudfront.net/reset.css);
@import url(https://d1lgo521xfi61.cloudfront.net/sidebar.css);
@import url(https://d1lgo521xfi61.cloudfront.net/buttons.css);
@import url(https://d1lgo521xfi61.cloudfront.net/forms.css);
@import url(https://d1lgo521xfi61.cloudfront.net/tables.css);
@import url(https://d1lgo521xfi61.cloudfront.net/pagination.css);

So it's not respecting the madmin namespace.

The assets are namespaced under madmin already, but setting an asset host may affect how that's handled. I'll have to look into that.

@kjf give #246 a try? I think using the relative paths was the culprit.
