Best way to customize CSS for tenants on a multi-tenant app?

Question

I'm using the Apartment gem to build a multi-tenant app (each tenant lives in a different Postgres schema).

What's the best way in Rails to define custom CSS overrides for each tenant?

I'm not asking for code. Just semantics on what's the "rails way" of doing this. — Jacob, Jun 07 '15 at 04:27
You could have some key values a admin or a tenant can change on the DB. I like to call this table settings and the relationship would be setting belongs_to tenant. and tenant has_one setting. — MZaragoza, Jun 07 '15 at 13:17

Given that multi-tenancy is itself a deviation from the rails way of doing things, I am not sure there a definitive answer to be provided here.

I recommend the following approach, which I think fits well with your use case:

In your layout:

<html>
<head>
  <%= stylesheet_link_tag "tenant_#{@tenant_name}" %>
</head>
<body class="tenant-<%= @tenant_name %>">
</body> 
</html>

In your scss files:

For each tenant (say t1) you can have:

tenant_t1.css.scss

body.tenant-t1 {
  ... stylesheets specific to tenant 1 scoped within tenant-specific class ...
}
