Rails 4 Notes

Lessons that I've learned before

• <%= form_for ... %> instead of <% form_for ... %>
• Chrome won't let you POST a form to local test instance, only GET. Firefox is OK.

New lessons

Routes

Routes need to be explicit (like a white list) to enhance security.

get 'tasks' => 'task#index'
get 'publications' => 'root#publications'
get 'tasks/download_request' => 'task#download_request'
post 'tasks/download_request' => 'task#download_request'

Can also use resources.

Strong parameters

jQuery

rails generate jquery:install

asset pipeline

add this to get javascript:

<%= javascript_include_tag "application" %>
