How to handle gemstone URLs

Question

I use stone apartmentfor multi-tenancy.

Everything works fine except for the URLs in my emails. Therefore, for each letter that is sent from any requests and from background jobs, it is used default_url_optionsfor the host.

Any suggestions on how to handle the host key in emails?

Answer 1

Another idea for a monkey patch:

# app/models/action_dispatch_routing_subdomain_extension.rb

module ActionDispatch::Routing

  module RouteSetExtensions

    # This allows lambdas as subdomain parameter for `default_url_options`:
    #
    #    config.action_mailer.default_url_options = {
    #      host: 'example.com',
    #      protocol: 'https',
    #      subdomain: lambda { ... }
    #    }
    #
    def url_for(options, route_name = nil, url_strategy = ActionDispatch::Routing::RouteSet::UNKNOWN)

      if options[:subdomain].respond_to? :call
        options[:subdomain] = options[:subdomain].call
      end

      if Rails.application.config.action_mailer.default_url_options[:subdomain].respond_to? :call
        options[:subdomain] ||= Rails.application.config.action_mailer.default_url_options[:subdomain].call
      end

      super(options, route_name, url_strategy)

    end
  end

  class RouteSet
    prepend RouteSetExtensions
  end

end

Initializer:

# config/initializers/action_dispatch_routing_subdomain_extension.rb
require 'action_dispatch_routing_subdomain_extension'

Then you can simply use lambda in the definition of the subdomain:

# config/environments/production.rb

Rails.application.configure do
  # ...

  config.action_mailer.default_url_options = {
    host: 'example.com',
    protocol: 'https',
    subdomain: lambda { Apartment::Tenant.current }
  }
end

Answer 2

, default_url_options . lib/dynamic_url_options :

module ActionDispatch::Routing
  class RouteSet

    alias_method :original_url_for, :url_for

    def url_for(options, route_name = nil, url_strategy = UNKNOWN)
      dynamic_options = Rails.application.config.respond_to?(:dynamic_url_options) ? Rails.application.config.dynamic_url_options.call : {}
      options = options.merge(default_url_options).merge(dynamic_options)

      original_url_for options, route_name, url_strategy
    end
  end
end

- :

config.action_mailer.default_url_options = {
  host: 'yourdomain.com'
}

config.dynamic_url_options = lambda {{
  subdomain: Apartment::Tenant.current
}}
