Assessment 4 - practice

You have 2 hours for the assessment.

This assessment will focus on a simple CRUD app with authentication. You will have to model users, links, and comments, along with session management.

Windows Users: Please use one of our workstation machines for the assessments.

Schema

Users have a username, password_digest, and session_token. Links have a title and url; each belongs to a User. Comments have a body; each belongs to a User and a Link.

Specs

Run the specs as you solve the assessment. The tests are intended to be run in this order:

bundle exec rspec spec/models/user_spec.rb
bundle exec rspec spec/controllers/application_controller_spec.rb
bundle exec rspec spec/features/auth_spec.rb
bundle exec rspec spec/features/links_spec.rb
bundle exec rspec spec/features/comments_spec.rb

If a failing spec confuses you, look at the spec file to see if you can discern what it is asking of you. You may also wish to add save_and_open_page to a spec to see what Capybara sees.

Note that a common mistake relates to capitalization; Capybara needs to have the text of links and buttons exactly match what it expects.

As ever, please ask your TAs any questions. If you get stuck or don't know why something is failing; ask. TAs will let you know whether they can answer your question, so ask anything. Don't use internet or prior notes, please.

Database Config

Every time you run bundle exec rake db:migrate, also run bundle exec rake db:test:load. db:migrate only updates the development database; db:test:load updates the test DB schema to mirror the development DB.

You can combine both commands into one:

bundle exec rake db:migrate db:test:load

BCrypt Hints

• Use BCrypt. You must not store passwords in the DB.
• BCrypt::Password.create(password) digests a password and builds a Password object.
• BCrypt::Password.new(digest) builds a Password object for the digest.
• BCrypt::Password#is_password?(password) checks if a password matches a digest.

Submission

• Rename the directory "#{first_name}-#{last_name}".
• ZIP it (you can use OS X's built in zip functionality)
• Use either .tar.gz or .zip; no boutique formats please :-)

Good luck!
