How to show more attributes in each element of the collection with collection_select

How to show select menu for two models?

I think better way to do is to use polymorphic association.

class Price
    belongs_to :pricable, polymorphic: true
end

class Product
    has_one :price, as: :priceable
end

class Service
    has_one :price, as: :priceable
end

Then, in your form, you can use:

<%= form_for [@priceable, Price.new]

where @priceable is a product or a service.

Try

scope :myScope1, where("myField IS NULL or CAST(myField as text) = ''")

It's not that simple as blank?, but I can't see a simple enough solution.
