I have a class which stores as one of its attributes a day of the week as an integer (0-6, 0=Sunday, standard UNIXy values). I want, obviously, the views to show the weekday name and the forms to provide a drop-down with the weekday names. Essentially it''s a vrtual attribute whose value is the localized weekday name, which maps to the integer value that''s actually stored. There are a lot of approaches, but I was wondering what the idiomatic Rails-y way of doing it is. Should I create a Weekday class? It wouldn''t be backed by the db - that''s not localizable or DRY... Any help appreciated. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

One is how you deal with the data readably in your code, the other is rendering a localized version.> There are a lot of approaches, but I was wondering what the idiomatic > Rails-y way of doing it is.

Now you can deal with days by string. (Probably a better choice is to make that an array of symbols and deal with them by symbol.) Once you get to the rendering phase, just have your local substitutions based on the internal symbols.> Any help appreciated.--Greg --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''ve done a similar thing with Periods of time ( e.g. daily, weekly, monthly ) where I wanted the value stored as an integer number of days. To do this I created a Struct for Period and then set a constant pointing to a hash of populated Periods. hth, -jc Gregory Seidman wrote:> On Thu, Aug 23, 2007 at 07:38:27PM -0000, Zeekar wrote: > >> I have a class which stores as one of its attributes a day of the week >> as an integer (0-6, 0=Sunday, standard UNIXy values).

Ok, for the display I made a new FormBuilder subclass and added a
select_weekday method. To get the localized weekday names, it does
this:
Date.new(2001,1,weekday_number+7).strftime("%A")
Someone please tell me a better way. :)

It seems that Date#strftime doesn''t honor locale settings, which is odd since strftime(3) does. So that code returns the same output as just doing Date::DAYNAMES[weekday_number]. I''ll have to look into some other way to get at the localized names...
