Example text

A UTHENTICATE REST C LIENTS This is a standard form, but notice that it uses the session_path helper in the form_tag. In this case, the form will issue an HTTP POST to /session. 1 We’ll also need some links to let folks log in and out. erb <% if logged_in? -%> <%= link_to 'Logout', session_path, :method => :delete %> <% else -%> <%= link_to 'Login', new_session_path %> <% end -%> At this point we have the session resource all ready to go and a way for users to log in and out. But we make the rules around here, and we say you have to be logged in to use the site.

In 2005 he started working professionally with Ruby on Rails and is now best known for his work on Railscasts, the free Ruby on Rails screencast series. Problem Most of the form code you see handles one model at a time. That’s not always practical. Sometimes you need to create and/or update two (or more) models in a single form, where there is a one-to-many association between them. Solution Let’s say we’re keeping track of tasks we need to do on projects. When we create or update a project, we’d like to add, remove, and update its tasks in a single form.

The Web already has the answer: HTTP basic authentication. site = "http://mike:secret@localhost:3000" end This slips the encoded login and password into the HTTP headers sent by the client to our Rails application. Note that because we’re using the HTTP protocol, the encoded login and password will be sent in plain text. This isn’t a big deal when we’re talking to a local app in development mode. However, it’s a huge deal if we’re talking to our production app. The login and password will travel across the ’net in plain-text form, and any hacker worth his salt can decode this over lunch.
