Rails 3.1 pass data through a post

In my application, I've a 'warehouse' model that own several fields such as id,name,description, etc, and a boolean field called 'done'.

In my view, I want to insert a button or link field,which, when clicked, should set (through HTTP POST method) warehouse.done = true How can I do this?

Notes: User cannot input warehouse.done field so I suppose to pass it to application as hidden field

Use link to with remote option.

<%= link_to "Vote", {:controller=>"your_controller_name", :action => 'vote',:id=>@warehouse.id, :vote=>true}, :remote=> true, :method => :put %>

In your controller

def vote
  @warehouse = Warehouse.find(params[:id])
  @warehouse.update_attribute(:vote, params[:vote])
  respond_to do |format|
    format.js
  end
end

In your routes file

resources :your_controller_name do
  collection do
   put 'vote'
  end
end

In your voting view page add new DIV to display flash notice.

<div id="flash_notice" style="display: none;"></div>

Create new RJS template "vote.js.erb" with following code.

$("#flash_notice").html("You have voted successfully");
$("#flash_notice").show("slow");

Let me know if you have any problem.

I made a couple of assumptions on the views, controller.

html

<a href="#" id="set-warehouse-done"> DONE </a>
<input id="warehouse-id" type="hidden" value="24">

js

$(document).ready(function() {
  $('#set-warehouse-done').click(function() {
    $.ajax({
      url: '/warehouse/' + $('#warehouse-id').attr('value');
      type: 'POST'
      data: done: true
    });
  });
}

warehouse_controller.rb

def update
  @warehouse = Warehouse.find(params[:id])
  if params[:done]
    if @warehouse.update_attributes(:done, params[:done])
      flash[:notice] = 'Warehouse updated successfully'
    else
      flash[:error] = 'Could not update warehouse'
