Hello,
Have a question related scope definition. I need to define a scope
based on related model attribute values like this.
class Product < ActiveRecord::Base
belongs_to :currency
scope :with_currency, lambda { |currency|
unless currency.to_s.upcase == ‘ALL’
here I need to define a scope that would test for currency.char_code
to match a passed value
something like… This is where I need help
where("currency.char_code = ?", currency.to_s.upcase)
end
}
end
class Currency < ActiveRecord::Base
attr_accessor : char_code
end
class LineItem < ActiveRecord::Base
belongs_to :product
scope :with_currency, lambda { |currency|
unless currency.to_s.upcase == ‘ALL’
here is another scope where I need help…
where("product.currency.char_code = ?", currency.to_s.upcase)
end
}
end
Thanks for suggestions. Still learning the scoping magic.
