In rails 3, how to create a Dropdown from hash I have following code in my User class class User ... other codes key :gender, Integer # i use mongo db class << self def genders() # not sure how to define static value, so do in this way genders = { ''1'' => ''Male'', ''2'' => ''Female'', ''3'' => ''Secret'' } end end end In the user form, i am trying to create a gender dropdown list <%= f.collection_select nil, :gender, User.genders, :key, :value %> but it complain undefined method `merge'' for :value:Symbol So what is the proper way to create the dropdown?
