I guess you want to implement some kind of multi-tenant application using PG separate schemas for each tenant.

In that case, if your application uses a single thread per request you should be able to achieve that by using an around filter to set the search path.

I think this is the easiest way to achieve what you want if I guessed it correctly.

Can I do this dinamically and is it thread-safe?

    This is achievable by setting the table in the model Bar to
    foo.bar, is that what you meant?

        Hi. I was thinking in the possibility to set a namespace for
        tables in AR queries, so instead of setting the search path
        like this:

              ActiveRecord::Base.connection.schema_search_path = 'foo,
        public'

        We specify the schema in the query:
        select * from foo.bar;

         so it could be a thread-safe solution and work with
        multi-thread environments and improve Rails support for real
        multi-tenant apps using Postgres schemas. What do you guys think?
