Rails link_to helper

Question

I have following route in my rails application:

recipient_template DELETE /templates/:id/recipient/:recipient_type/:recipient_id(.:format) 

How can I create a link in my view to this specific route given that both recipient type and recipient id are dynamically filled by my application.

Here is my model and route.rb file

class Template < ActiveRecord::Base
     has_and_belongs_to_many :individuals
     has_and_belongs_to_many :groups

     def recipients
         {:groups => self.groups, :individuals => self.individuals}
     end
end

resources :templates do
    member do
        match 'recipient/:recipient_type/:recipient_id', :to => :recipient_remove, :via => :delete
    end
end

Answer 1

Try this

pass recipient_type and recipient_id values in path along with template id

link_to "Delete Recipient", recipient_remove_path(template.id, recipient_type, recipient_id), method: :delete

In your routes

match 'recipient/:recipient_type/:recipient_id' => "controller#action", :as => :recipient_remove, :via => :delete

and you should pass recipient class name in recipient type and id of recipients in reciepient_id
