I am pretty new to Ruby on Rails. Pardon me if it is a pretty basic
question.
I have a combo box built based on a Constant Array
PAYMENT_TYPES [
["MasterCard", "MC"],
["Visa", "VISA"],
["American Express", "AMEX"]
].freeze
I store the values (i.e. MC, VISA, AMEX) in my database...
When I display the information, I would like to display the keys (i.e.
MasterCard, Visa, American Express) to the user instead of MC, VISA,
AMEX.
How can I search PAYMENT_TYPES to get the keys given a value.
Any help is greatly appreciated.
Thanks

Figured it out.. PAYMENT_TYPES.rassoc("MC")[0] would give you "MasterCard" Thanks -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You could use a hash: PAYMENT_TYPES = { ''MC''=>''MasterCard'', ''VISA''=>''Visa'', ''AMEX''=>''American Express''] and then: PAYMENT_TYPES[''MC''] You should strongly consider storing the display names in the database as well. Your current setup distributes the business data across two different layers (database and domain model), which is generally not a good idea.
