Question

I have a rails 3.2 project.
There are a bid object and i want the user to be able to accept this bid!
How can i do this?
My first thought is about to make a new method on bids controller and in the method i have to update the accept boolean of bid.Something like that?

  def accept
    @bid = Bid.find(params[:id])
    @bid.subject ='accept!!!!'
    flash[:notice] = "Successfully destroyed post."
    respond_to do |format|
      format.html { redirect_to "/mybids" }
      format.json { head :no_content }
    end
  end

Answer 1

You’re question is a little vague, because it’s not clear what a bid is attached to, or what the other models are in your app, since you don’t say.

However, let’s say that this is an auction site, and auctions have bids. When a bid is accepted

• All other bids on that auction are destroyed
• The bid that was accepted has it’s accepted boolean field set to true.

If that is close to what you’re trying to do, then the code below should accomplish that.

in app/controllers/bids_controller.rb

# PUT /bids/:id/accept
def BidsController < ApplicationController
  def accept
    @bid = Bid.find(params[:id])
    @bid.update_attribute(:accepted, true)
    @bid.auction.bids.each do |rejected_bid|
      rejected_bid.destroy unless rejected_bid == @bid   # destroys all be the accepted bid
    end

    flash[:notice] = "Bid accepted."
    respond_to do |format|
      format.html { redirect_to "/mybids" }
      format.json { head :no_content }
    end
  end
end

Then you need to add a route for this action to your config/routes.rb file. Something like…

resources :bids do
  put :accept, :on => :member
end

Form the view, you would link to this route like this:

link_to "accept", accept_bid_path(@bid)

And if you call rake routes from your command line, you should see an entry that looks like this:

accept_bid PUT   /bids/:id/accept(.format)    {:action=>"accept", :controller=>"bids}
