lightscalar / Humanizing Model Attributes in Rails
Created December 24, 2009 15:38
Just discovered this: an easy way to humanize the attributes of a model. Allows you to rename the database column name to something more reasonable. Makes for nicer, more understandable error messages back to the user.
class User < ActiveRecord::Base
HUMANIZED_ATTRIBUTES = {
:user_email => "E-mail address"
}
def self.human_attribute_name(attr)
HUMANIZED_ATTRIBUTES[attr.to_sym] || super

:reject_if => proc { |attributes| attributes['name'].blank? }

lightscalar / Using RSPEC with AUTHLOGIC
Created September 2, 2010 16:10
So, this helps a lot when testing applications using RSPEC that use the authlogic gem for authentication.
Just require and include the following module in your rspec file. Then you can simply write things like:
before(:each) do
login_as_user
end
at the top of your specs, and you should be good to go...

lightscalar / time.strftime formatting
Created September 16, 2010 20:12
STRFTIME
time.strftime( string ) => string
Formats time according to the directives in the given format string. Any text not listed as a directive will be passed through to the output string.
Format meaning:
%a - The abbreviated weekday name (``Sun'')
%A - The full weekday name (``Sunday'')
%b - The abbreviated month name (``Jan'')
%B - The full month name (``January'')
%c - The preferred local date and time representation

lightscalar / Using Different Paths in Devise
Created October 23, 2010 15:38
Or: How to leave my UsersController the hell alone
We're working in a Rails 3 App with devise attached to the user model
In routes.rb, if we write:
devise_for :users, :path => 'u'
Then we can obviate all the problems with nested resources. Now users will be directed to /u/sign_in and so forth.
