Yet another rails tutorial. There are tons of these but I felt like making my own. My rails version at time of writing is 2.0.2. In this tutorial series we’ll be creating a basic cookbook website. The objective is to give the reader an introduction to software development in Ruby on Rails.
For windows be sure to change all slashes / to backslashes \.
First we start by creating the project:
$ rails cookbook ... ... bunch of files generated ... ... $ cd cookbook
Let’s create the scaffold for the Cookbooks. A “scaffold” is the bare bones you need for functionality. A model, a migration script, a controller, 4 views and a layout. It also creates tests and fixtures.
$ ruby script/generate scaffold Cookbook title:string author:string
This command will use the migration script generated above and create the database table “cookbooks” – Table names are plural.
$ rake db:migrate
Open new terminal window and navigate to cookbook directory and start the server:
$ ruby script/server
Point Browser to http://localhost:3000/cookbooks. You should see an empty list of all cookbooks. Create a new cookbook by clicking the New Cookbook link.
Okay, now let’s create the scaffold for the Recipes and migrate the database:
$ ruby script/generate scaffold Recipe name:string ingredients:text description:text number_of_servings:integer
Now update the database:
$ rake db:migrate
Point Browser to http://localhost:3000/recipes and create a new recipe.
Great! Now we have a functional Cookbook and Recipe model. But now we realize that we need to make recipes belong to cookbooks. We’ll do that in Rails Lesson #2.
