Quick Selection

Hello,

I remember reading about how to do this at some point, but I don't actually remember how to do it. If I have an object "order" that contains {noodle type, noodle date, noodle price}, how would I iterate through all existing "orders" and place all noodle types into an array, non repeating? Something like this:

    @orders = Order.find(:all)
    @types = @Orders.each.select(:type, :no-repeat)
     
    #@types => {wheat, white, corn, wet}  even if there are a bunch of wet noodles

Thank you

Found the solution elsewhere:

@types = Order.find(:all, :select => "distinct noodle_type").collect(&:noodle_type)

You might need an extra table to keep your types if you can change database structure, it will save lots of hassles in the long run.

model: NoodleType

And would be easy to

NoodleType.all.each do |noodle_type|
#....
end

Cool - thanks for that.
