I am using rails 3.0.9 and sqlite I have one form MoaObject in which there are two fields 1. Title (text fields) 2. Description(text area) I have made controller moa_objects controller and views(_form,index,edit,new,show) and title and description are added through form in moa_objects(CRUD) Now there is another CRUD CompanyMainObject in which I am having above fields(title,description) and here the title and description should be retrieve from MoaObject's table..and I want title in selectbox and description in text area.... I have bring title from moa_objects in select box...and now my problem is that as soon as one selects title its respective description should be set in textarea....I have gone to many blogs but I am not getting any solutions...I have try to use javascript and retrieve ID bygetselectedindex...but not work...

moa_objects_controller class MoaObjectsController < ApplicationController def index @moa_objects = MoaObject.find(:all) end

def new @moa_object = MoaObject.new end

def create @moa_object = MoaObject.new(params[:moa_object]) if @moa_object.save flash[:notice] = "Successfully created product." redirect_to @moa_object else render :action => 'new' end end

def show

@moa_object = MoaObject.find(params[:id]) end

def edit @moa_object = MoaObject.find(params[:id]) end

def update @moa_object = MoaObject.find(params[:id]) if @moa_object.update_attributes(params[:moa_object]) flash[:notice] = "Successfully updated product." redirect_to @moa_object else render :action => 'edit' end end def destroy @moa_object = MoaObject.find(params[:id]) @moa_object.destroy flash[:notice] = "Successfully destroyed product." redirect_to moa_objects_path end

end

form of moa_object <%= form_for(@moa_object) do |f| %>

<div class="field"> <br>     <%= f.label :title %><br>     <%= f.text_field :title %> <br> </div> <div>     <%= f.label :description %><br>     <%= f.text_area :description %> </div>

<div class="actions">     <%= f.submit "Save" %>

</div> <% end %>

CompanyMainObjectsController class CompanyMainObjectsController < ApplicationController

def index @company_main_objects = CompanyMainObject.find(:all) @moa_objects = Moa.find(:all) end

def new @company_main_object = CompanyMainObject.new end

def create @company_main_object = CompanyMainObject.new(params[:company_main_object]) if @company_main_object.save flash[:notice] = "Successfully created product." redirect_to @company_main_object else render :action => 'new' end end

def show @company_main_object = CompanyMainObject.find(params[:id]) end

def edit @company_main_object = CompanyMainObject.find(params[:id]) end

def update @company_main_object = CompanyMainObject.find(params[:id]) if @company_main_object.update_attributes(params[:company_main_object]) flash[:notice] = "Successfully updated product." redirect_to @company_main_object else render :action => 'edit' end end def destroy @company_main_object = CompanyMainObject.find(params[:id]) @company_main_object.destroy flash[:notice] = "Successfully destroyed product." redirect_to company_main_objects_path end

end

CompanyMainObject

<%= form_for(@company_main_object) do |f| %> <%= f.collection_select :object_id,MoaObject.all(:order => "id"), :id, :title%> <%= f.label :description %> <%= f.text_area :description %>/Now from above selected title I want respective description/

<%= f.hidden_field :client_id, :value => "#{params[:client_id]}" %> <%= f.submit "Save" %>

<% end %>
