Rails using arrays with forms & validation inclusion of

Question

Trying to get some good advice on the best approach to using arrays for form select but using the same array to test inclusion of for the validation.

Right now I have it but building the arrays within the elements and validation ie,

# Form
<%= f.select(:status, [['Live','live'], ['Paused', 'paused']]) %>

# Model
validates :status, :inclusion => { :in => %w(live paused) }

I'm sure there would be a better way to store these arrays and use them !

Thanks for any advise you can provide.

You can add these two constants to your model and then call the validation:

VALID_STATES = ["live", "paused"]
SELECT_STATES = VALID_STATES.map { |s| [s.capitalize, s] }
validates :status, :inclusion => { :in => Model::VALID_STATES }
