Under the Hat

Today I’ve pushed a few updates to the Roleify rails plugin.

The changes are

• you can now use ‘namespaced’ controllers
• I added a helper method to hide/show blocks for a specified role

Example

The initializer

Roleify::Role.configure("role_a", "role_b") do
  {
    :role_a => { :dashboard_issues =>  :all },
    :role_b => { :issues => "index" }
  }
end

So, role_a refers to a Dashboard::IssuesController and role_b refers to an IssuesController.

The helper

module ApplicationHelper
  include Roleify::RoleifyableHelper
end

The view

<% allowed?(Roleify::Role::ROLE_A) do %>
  // whatever you want for role_a eyes only
<% end %>

try is one of those small new additions in the Rails 2.3 release. Luckily I found out about it via a Railscast

What is it?

From the documentation:

Invokes the method identified by the symbol method, passing it any arguments and/or the block specified, just like the regular Ruby Object#send does. Unlike that method however, a NoMethodError exception will not be raised and nil will be returned instead, if the receiving object is a nil object or NilClass.

What did you just say?

The code above normally throws an exception if someobject is nil. By using try it just returns nil.

Don’t overuse this.

What do you need?

• OS X
• Java 6
• RubyMine

Next, open RubyMine’s Info.plist:

mate /Applications/RubyMine\ 1.0.5.app/Contents/Info.plist

Find the line with value 1.5* en change it to 1.6*.

Start RubyMine and check the ‘about’. It should look something like this:

Enjoy. It does feel snappier on my side.

On a sidenote: You can set the default Java version via the ‘Java Preferences’ app.
