Get the primary schema's name

If you’re using PostgreSQL and you’ve changed schema, sometimes you need to know what schema you’re in.

ActiveRecord::Base.connection.schema_search_path.split(",").first

Specify your own template

You can specify you own template this way:

def notice
  ...
  @template = "some_other_name.html.erb"
end

sort_by

array.sort_by {|element| [element.foo, element.bar.name, element.baz]}

If you want to do a find without the default scope...

Checkout with_exclusive_scope
