ruby-on-rails-3.1

I am using ruby on rails 3.1. And am trying to post html form data to controller for saving the record in database. But I am getting routing error like this 'No route matches [POST] first/save' .But when I tried to run this link in address bar like '127.0.0.1:3000/first/save' it is working fine. Can any one please tell me where am doing wrong. My routes are like: Rails.application.routes.draw do root 'first#hello' get 'first/save' end And my html form is like: <form accept-charset="UTF-8" method='post' action='/first/save'> <label for='S.No'>S.No</label> <input type="text" name="s_no"

respond_to do |format| if @user.save format.js { render :nothing => true, :status => :ok, :location => @user } else format.js { render :json => @user.errors, :status => :unprocessable_entity } end end All options I've tried (like putting respond_to :js at the top of controller, etc) don't quite work the way as in this. Rails 3 Format: Use respond_to :json and respond_with (@user) respond_to :json # You can also add , :html, :xml etc. def create @user= User.new(params[:user]) #---For html flash #if @user.save # flash[:notice] = "Successfully created user." #end respond_with(@user) end # Also,

I have to send weekly emails to all the user about the latest things happening. I am using ActionMailer to accomplish other mailing task however I have no clue how to automate the weekly emails. Update I found whenever gem which could be used to schedule cron jobs. I guess this could be used to send weekly emails which I intend to. Still looking how to make it work with ActionMailer will update once I find the solution Update 2 This is what I have done so far using whenever gem:- in schedule.rb every 1.minute do runner "User.weekly_update", :environment => 'development' end in users_mailer.rb

I am writing ruby on rails app, that will have 2 different types of users (let's say sellers and buyers). I was thinking about using single table inheritance, but ultimately I decided to crate 2 separate models (I believe it's better solution in my case). The problem is when I try to create private message model (both sellers and buyers can contact each other). Typically I would just generate model called message with 3 fields (from_user_id to_user_id and content). This will not work in my case, because there might be 2 users with the same id (1 seller and 1 buyer). I was thinking about using

I created a simplistic achievements system and wanted to introduce delayed_job (2.1.4) to take care of the processing. However, the handler column in the delayed_jobs table is always nil, which results in the last_error text: Job failed to load: instance of IO needed. Handler nil Here is my setup: Achievement Observer class AchievementObserver < ActiveRecord::Observer observe User, Comment, ... def after_create(record) # initiate delayed job to check conditions Delayed::Job.enqueue(TrophyJob.new(record.id, record.class.name)) end ... end Trophy Job class TrophyJob < Struct.new(:record_id,

Currently I have an each loop in the template for where the comments are display. Say a user has 50 comments to a micropost they have posted. A long list showing 50 comments will be displayed. To save space on the page I've decided I'd like to limit comments shown to 2-3 per micropost. If a user wishes to view more they can click "view more" or "view all". I'm wondering how a server would cope if there were like 10,000 comments and a user clicked "view all" which is why I may choose to implement "view more" then have like 50 more comments shown" Anyway I'd like to know a good way to limit the
