scope   with_scope  

Public Instance methods

The current scope set, should be used in the block passed to with_scope.

What with_scopes focuses on is scoping the query when finding the object and the name of the cookie / session. It works very similar to ActiveRecord::Base#with_scopes. It accepts a hash with any of the following options:

  • find_options: any options you can pass into ActiveRecord::Base.find. This is used when trying to find the record.
  • id: The id of the session, this gets merged with the real id. For information ids see the id method.

Here is how you use it:

  UserSession.with_scope(:find_options => {:conditions => "account_id = 2"}, :id => "account_2") do
    UserSession.find
  end

Eseentially what the above does is scope the searching of the object with the sql you provided. So instead of:

  User.find(:first, :conditions => "login = 'ben'")

it would be:

  User.find(:first, :conditions => "login = 'ben' and account_id = 2")

You will also notice the :id option. This works just like the id method. It scopes your cookies. So the name of your cookie will be:

  account_2_user_credentials

instead of:

  user_credentials

What is also nifty about scoping with an :id is that it merges your id‘s. So if you do:

  UserSession.with_scope(:find_options => {:conditions => "account_id = 2"}, :id => "account_2") do
    session = UserSession.new
    session.id = :secure
  end

The name of your cookies will be:

  secure_account_2_user_credentials
