Hello all...

I am new to rails. I have a rails app in which i want data from my database table into a text file.

I have a notices table that has three fields - title, body and user. I want this data to be stored in a text or yaml file.

Here is the code of what I am trying to do... But I am not able to get it done.

def save   @notice = Notice.find(params[:id])          f = File.new("#{RAILS_ROOT}/public/notice.txt","w")     debugger   f.write @notice   f.close   end

Please help me.

@notice is an object. you need to write each attribute to the file.

f.write @notice.title f.write @notice.body f.write @notice.user

Thank you for your reply... I am posting code for my controller - notices. The save method is at the last. I am not able to link and call this method and its not working as well. Please correct the code and help me.

class NoticesController < ApplicationController

  def index     @notices = Notice.all

    respond_to do |format|       format.html # index.html.erb       format.xml { render :xml => @notices }     end   end

  def show     @notice = Notice.find(params[:id])

    respond_to do |format|       format.html # show.html.erb       format.xml { render :xml => @notice }     end   end

  def new     @notice = Notice.new

    respond_to do |format|       format.html # new.html.erb       format.xml { render :xml => @notice }     end   end

  def edit     @notice = Notice.find(params[:id])   end

  def create     @notice = Notice.new(params[:notice])

    respond_to do |format|       if @notice.save         flash[:notice] = 'Notice was successfully created.'         format.html { redirect_to(@notice) }         format.xml { render :xml => @notice, :status => :created, :location => @notice }       else         format.html { render :action => "new" }         format.xml { render :xml => @notice.errors, :status => :unprocessable_entity }       end     end   end

  def update     @notice = Notice.find(params[:id])

    respond_to do |format|       if @notice.update_attributes(params[:notice])         flash[:notice] = 'Notice was successfully updated.'         format.html { redirect_to(@notice) }         format.xml { head :ok }       else         format.html { render :action => "edit" }         format.xml { render :xml => @notice.errors, :status => :unprocessable_entity }       end     end   end

  def destroy     @notice = Notice.find(params[:id])     @notice.destroy

    respond_to do |format|       format.html { redirect_to(notices_url) }       format.xml { head :ok }     end   end

  def save      @notice = Notice.find(params[:id])      f = File.new("#{RAILS_ROOT}/public/jar/notice.txt","w")     f.write @notice.title     f.write @notice.body     f.write @notice.user_name     f.close     end
