Rails routes exclude domain from constraints host-CodePudding

In my Rails 6 app I have a few subdomains using a set o routes. To make those routes only available to certain subdomains I use:

constraints(:host => 'app.example.com') do
  scope :module => :ui do
    # Some resources and additional routes here
  end
end

Is there a way to make a set of routes available to all subdomains except this one

constraints(:host IS NOT 'app.example.com') do
  scope :module => :ui do
    # Some resources and additional routes here
  end
end

This IS NOT is phantom code so make clear what I would like to achieve. The routes should only be available if the subdomain IS NOT app.example.com

CodePudding user response：

We use something like this to make host specific constraint. Let me know if this works for you.

scope constraints: lambda { |req| req.host != 'app.example.com' } do
  # Some resources and additional routes here
end

CodePudding user response：

We can use advanced constraint as well

class RestrictedConstraint
  def self.matches?(request)
    !['localhost', 'app.example.com'].include?(request.host)
  end
end

Rails.application.routes.draw do

  scope constraints: RestrictedConstraint do
    # Some resources and additional routes here
  end

end
