Hi James,
Sorry to bother you again. I wonder how do I display a drop down list
for a data field. For example, I want to display different types of
license_types (Group License and Single License) on the generate new
license form.
I added below codes in my license.rb controller, but it does not take.
I do not how to have the hobo to pass the value and display it on the
form.
license_type = [
["Personal License"],
["Group Licesne"]
]
validates_inclusion_of :license_type, :in => license_type.map {|disp,
value| value}
******** license.rb*
class License < ActiveRecord::Base
hobo_model # Don't put anything above this
fields do
license_type :string
quanty :integer
key :string
expiration_date :date
timestamps
end
