Introduction

A curious developer and tech enthusiast never miss an opportunity to learn a little more every day! I can absolutely relate to this urge to learn. So, keeping your curiosity in mind, we are back with another Rails tutorial on how to dockerize rails applications with the help of Docker Compose. Hoping that you are familiar with what is Docker and why do we need Docker.

Let’s get started with the app development and dockerizing it.

Create a Rails App

Fire the following commands to create a rails app.

Prerequisites: Dockerize Rails Application

As we are implementing Docker Compose, make sure about the following installations before getting started.

Install Docker Community Edition

Install Docker Compose

Create a Dockerfile

The Dockerfile is the foundation of any Dockerized app. It contains all the instructions for building the application image. You can set this up by installing Ruby and all of its dependencies. The Dockerfile consists of the following instructions.

Michael Hartl's Ruby on Rails 4.0 Tutorial - @mhartl @railstutorial #ruby #rails #ror

Ruby on Rails, even eight years after its first release, is still recognized as one of the best frameworks for Web applications for many reasons, not the least of which are its cost (it’s free) and its scalability (sites as big as Twitter have used it).

Rails 4.0 was released last year, and soon after, Michael Hartl updated his famous Rails Tutorial.

For those wanting to learn RoR, the Rails…

This post is a week late.

For the past three weeks now, I've been working with a friend on a new website for a local restaurant. It's my first actual client work. It's been challenging, educational, fun...and time-consuming.

Not wanting to stray from my Weekly Website project, not wanting slow down on the restaurant site, and not wanting to quit my job for extra time and put my family on the street, I realized that something had to give. I needed a project that would be valuable to me but wouldn't take a ton of time.

That's why I decided to work through Michael Hartl's Rails Tutorial again.

So I am working thorugh Michael Hartl's video tutorial on Ruby on Rails (http://railstutorial.org). The tutorial is a bit older using Rails 3.2 and Ruby 1.9 (I believe) and some older gems.

I am working with the current versions of Rails 4.0 and ruby 2.0. So I came to the point where he is testing the titles of some pages with Rspec and it would not work. I searched a long time for reasons these test are failing.

Turns out Capybara doesn't test for object that are not visible on the page anymore. And a link further it tells me about some workarounds and that the new Capybara has a method for testing page titles. So update to Capybara 2.1.0 (from 1.1.2)...

Apparently in Capybara 2.x some things have changed and the "visit" method in the test is suddenly undefined.

Solution is to move the static_pages_spec.rb from spec/requests folder to spec/features and include the following line of code in spec_helper.rb:

#insert after "RSpec.configure do |config|" config.include Capybara::DSL, :type => :feature

and rewrite the title test like this

page.should have_title 'About us'

So its always a natural feeling when you want to start blogging so badly but can't think of anything/where to start off. Following the thought i ended up deciding that i'm gonna blog almost anything that comes in my mind.

Its 9ish and dinners about to be served. Started my first chapter from railstutorial. Seems to be a good resource if your just starting out programming from a long break( that i'm ) and willing to learn something as new and good as Rails.
