module Waves module Helpers # Model helpers allow you to directly access a model from within a view. # This is useful when creating things like select boxes that need data # from anther model. For example, a Markaby select box for authors might look like: # # select do # all(:user).each do |user| # option user.full_name, :value => user.id # end # end # # You could also use these within a view class to keep model-based logic out # of the templates themselves. For example, in the view class you might define # a method called +authors+ that returns an array of name / id pairs. This could # then be called from the template instead of the model helper. # module Model def model( name ) Waves.main::Models[ name ][ domain ] end # Just like model.all. Returns all the instances of that model. def all( model ) model( model ).all end # Finds a specific instance using the name field def find( model, name ) model( model )[name ] rescue nil end end end end
