Ruby on Rails Tutorial sample application
This is the reference implementation of the sample application from Ruby on Rails Tutorial: Learn Web Development with Rails (6th Edition) by Michael Hartl.
To get started with the app, first clone the repo and
cd into the directory:
$ git clone https://github.com/mhartl/sample_app_6th_ed.git $ cd sample_app_6th_ed
Then install the needed gems (while skipping any gems needed only in production):
$ bundle install --without production
Next, migrate the database:
$ rails db:migrate
Finally, run the test suite to verify that everything is working correctly:
$ rails test
If the test suite passes, you'll be ready to run the app in a local server:
$ rails server
The reference app repository includes a separate branch for each chapter in the tutorial (Chapters 3–14). To examine the code as it appears at the end of a particular chapter, simply check out the corresponding branch using
$ git checkout <branch name>
A full list of branch names appears as follows:
static-pages rails-flavored-ruby filling-in-layout modeling-users sign-up basic-login advanced-login updating-users account-activation password-reset user-microposts following-users
Starting in Chapter 10 (“Updating users”), the sample app comes configured to seed the database with sample users, which you can activate by resetting the database and then running the seed program:
$ rails db:migrate:reset $ rails db:seed
Help with the Rails Tutoiral
Experience shows that comparing code with the reference app is often helpful for debugging errors and tracking down discrepancies. For additional assistance with any issues in the tutorial, please consult the Rails Tutorial Help page.
