POHow can I pass parameters to nested resources for single table inheritance in Ruby on Rails?

copied!<p>I am having some difficulties passing in parameters to my controller. I created an Single table inheritance model in my model file.</p> <pre><code>class Account < ActiveRecord::Base belongs_to :user end class AdvertiserAccount < Account end class PublisherAccount < Account end </code></pre> <p>I setted up my routes table with nested resources</p> <pre><code>resources :advertiser_accounts do resources :campaigns end </code></pre> <p>I want to be able to pass the current account_id (an account_id from one of my two subclasses of account) to my campaign controller file. A URL that I would use is <a href="http://127.0.0.1:3000/advertiser_accounts/1/campaigns" rel="nofollow">http://127.0.0.1:3000/advertiser_accounts/1/campaigns</a> Since my resource for the url is advertiser_accounts and not accounts, I am not able to get the parameter :account_id. </p> <pre><code>class CampaignsController < ApplicationController def index @account = current_user.accounts.find_by_id(params[:account_id]) end end </code></pre> <p>is there a shortcut to get the current resource or the id? Am I passing in parameters correctly? It seems confusing to call many find_by_id in the controller. Any help is appreciated.</p> <p><strong>Edit Possible solution:</strong> One of the solutions that I was thinking was setting a type in my routes and then in my controller I would use case statement then get params[:advertiser_account_id] but that seems very tedious and messy. Especially if I will need to copy and paste a list of case statements in each action. </p> <p>routes.rb</p> <pre><code>resources :advertiser_accounts, :type => "AdvertiserAccounts" do resources :campaigns end </code></pre> <p>campaigns_controller.rb</p> <pre><code>def index case params[:type] when "AdvertiserAccounts" @account = current_user.accounts.find_by_id(params[:advertiser_account_id]) when "PublisherAccounts" @account = current_user.accounts.find_by_id(params[:publisher_account_id]) end end </code></pre>
