simple collection_select problem.
Hi,
I can do this :
collection_select "state", :id, TrainingState.find_all,:id,:name
but not this :
collection_select "state[]", :id, TrainingState.find_all,:id,:name
Anyone any idea why? Is there something about collection_select that
does not allow collections?
Thanks
Chris

why belongs_to does not like validation?
This works :
class Recipe < ActiveRecord::Base
belongs_to :category
end
But (when I add validation) this does not work :
class Recipe < ActiveRecord::Base
belongs_to :category
validates_length_of :category, :within => 6..20
validates_uniqueness_of :category, :message => "already exists"
end
thank you

Suppose I have a Recipe model. Let''s simplify things and pretend that

categories.
We also assume that I have generate
