Separate Domain for Namespaced Routes in Rails 4

Question

I\'m working on a Rails 4 app. One part of the app is a customer portal that has to be accessed from a separate domain.

I have everything working fine by navigating

Answer 1

This answer can be useful for the rails routes problem:

Rails routing to handle multiple domains on single application

Shortened:

1) define a custom constraint class in lib/domain_constraint.rb:

class DomainConstraint
  def initialize(domain)
    @domains = [domain].flatten
  end

  def matches?(request)
    @domains.include? request.domain
  end
end

2) use the class in your routes with the new block syntax

constraints DomainConstraint.new('mydomain.com') do
  root :to => 'mydomain#index'
end

root :to => 'main#index'

or the old-fashioned option syntax

root :to => 'mydomain#index', :constraints => DomainConstraint.new('mydomain.com')
