Question

after we create an new entry the standard redirect is everytime to the :id. how can i change it to an own_key.
We have designed our routes

resources :lists
match '/:own_key' => 'lists/show'

If we create an new entry the redirect go to /list/:id

Is there a way to change it to redirect to own_key?

def create
  @list = List.new(params[:list])
  @list = List.create!(params[:list])
  respond_with(@list)
end

Answer 1

Each model has a method called to_param which you can override

list.rb

class Bar < ActiveRecord::Base
  def to_param
    "#{own_key}.parameterize"
  end
end

This will make that the path changes from /:id, to /:own_key.

NOTE: This will change only the value of the parameter but not the name of the parameter.

Example: If you want to acces with an own_key value of foo the show action /lists/foo there will not be a params[:own_key]. You can access the own_key value by with params[:id] but not with params[:own_key]

Parameters: {"id"=>"foo"}
