- PK_KEYS =
Using this order for keys because it makes it easier to query fos records. If you had a key like “MERE.0.8.40443.1259” for a trip leg and you did this: TripLeg, you would get a trip leg You still have to massage this key alittle to make the query: see Sequel.fos_id_to_lookup_key in core_patch.rb

.column_view(column_name, type, custom_method_name = nil) ⇒ Object
define a method to get the value of set the column as a certain type Used like this in a Model class.
column_view :'column_name', :date
column_view :'column_name', :time
column_view :'column_name', :time, :custom_method_name
column_view :'column_name', :currency
column_view :'column_name', :boolean
defines methods for getting new value in the type you requested from the column_name. The type should be :time, :date, :currency, or :boolean
For example: column_name :eta_local, :date, the methods created are:
eta_local_date => returns a Date
eta_local_date_view => returns a Date formatted y-m-d
eta_local_date_view_mdy => returns a Date formatted m/d/y
eta_local_date_view_mdy_ipc => returns a Date formatted m/d/y with first 0 chopped
ie. instead of 08/07/2009 .. it will be 8/07/2009
column_name :eta_local, :time, the methods created are:
eta_local_time => returns a Time
eta_local_time_view => returns a Time formatted H:M
column_name :price, :currency, the method created is:
price_currency => which returns a currecy formatted value 12.15 ( no dollar sign )
column_name :item_total, :delimited, the method created is:
item_total_delimited => which returns a delimited formatted value 12.15 ( no dollar sign )
column_name :paid, :boolean, the method created is:
paid_boolean => which returns a string ("False" / "True") for values ( 0 / 1 )

#fill_hash(attributes) ⇒ Object
Passing in an array of attribute / method names, fills a hash with values from the model. Can pass in attributes with __ like :passenger__name and the ‘name’ value will be delegated to ‘passenger’ with the delegator being created on the fly. Can also pass in a hash of attributes, with the key being the key you want for the hash and the value being the value you want from the model. So you could pass in :pax_name=>:passenger__name and the hash returned will be :pax_name=>‘Bob’
