[Rails] how to create dropdown from a hash in rails 3

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?

Thanks
