Question

I defined one of my custom method in PostsController as follows:-

class PostsController < ApplicationController
 ...<<other methods truncated from display >>
  public
    def update_bid_winner (winner_id)
    @post.bid_winner_id = winner_id
    @post.save
  end  
end  

But when I try to call it from some other controller (BidsController in my case). Where Bid is a nesteded resource of post:-

resources :posts do
  resources :bids do
    member do
      get 'offer_bid'
    end
  end
 end  

I tried to call my custom method as follows from the bids controller :-

 def offer_bid
   @post = Post.find(params[:post_id])
   @bid = Bid.find(params[:id])
   @post.update_bid_winner(@bid.user_id)  <<<<<<<<<< Here goes the call
   @post.save
    redirect_to post_path(@post)
end

But I get an error saying that undefined method update_bid_winner :-

undefined method `update_bid_winner' for #<Post:0xb68114f4>  

Help me out. am I doing anything wrong here? If so , please suggest ways to achieve the same !!

Thanks in Advance.

PostsController and Post are two different classes. Notice how @post is a Post object: @post = Post.find(params[:post_id])

Define the method in app/models/post.rb instead of app/controllers/posts_controller.rb.
