What's the correct way to run one controller action from another controller action without an HTTP redirect?

Question

I\'d like to be able to dispatch from one controller action to another conditionally, based on a combination of query parameters and data in the database.

What I hav

Answer 1

Instead of calling code across actions, extract the code to lib/ or something, and call that code from both controllers.

# lib/foo.rb
module Foo
  def self.bar
  # ...
  end
end

# posts_controller
def index
  Foo.bar
end

# things_controller
def index
  Foo.bar
end
