Pr-request for Ruby on Rails tutorials

  1. Install linux Operating-System from here .
  2. Install RVM , Ruby and Rails from here.
  3. Go through our previous tutorial introduction to rails.

In my previous post I discussed about Rails framework and now we will start from basics of rails. In these series of ruby on rails tutorials, we will make a dynamic web project, we will discuss about that in our future posts. We will also post video tutorial with it for your convenience. Let’s start from creating new project in Ruby on Rails. Follow the steps below:

  1. Open your terminal by using 
    ctrl+alt+T
  2. Now make new directory/ folder 
    mkdir work
  3. Enter this command to make new rails project 
    rails new Buffercode -d mysql

    Here Buffercode is your project name, and make sure you have Internet connection at that time. rails will install some gem files.
    Rails uses sqlite as default database, you can change it later or use -d mysql as option as in above command rails new Buffercode -d mysql

  4. change your directory using cd command 
    cd Buffercode
  5. Now Enter below command to install missing gems 
    bundler or
bundle install
  6. And now finally run your server using command below 
    rails server or
rails s
  7. Now just check it by open your browser and type localhost:3000 , a screen will be open as shown in below image.

Explore what we did by using these simple commands

Open your work directory and you will find a new directory named Buffercode<your project name>. When you will open the directory Buffercode, you will find some new directories and files. You can check it from below image .
Ruby On Rails Tutorial : Creating new project

When you will open its first folder named as app, you will find some new folders including controllers, models and views , which shouts that rails is a MVC framework as we told you in our previous tutorial .
Rails accepts incoming requests from a browser, decodes the request to find a controller from controllers and calls an action method in that controller.
The controller then invokes a particular view from views folder to display the result to the user using models which take care of database. Rails takes care of most of the internal plumbing that links all these actions.

Models View               Controller Route
Deals with data Uses for front-end views Control the actions(uses to write business logics) Connect view and controller

  1. I follow the instuction here, but when I run
    $ rails server

    it says there is no database buffercode_development.
    I think before run
    $ rails server

    run :
    $ bundle exec rake db:create

    to make sure the database is being created by rails.

    and voila, the app is ready at localhost:3000
    CMIIW.
