Question

I’m using the rails3-jquery-autocomplete gem to autocomplete the name of a user, search attribute is lastname but I want to display full name as the display value. Here’s what I have in my controller

autocomplete :customer, :lastname, :display_value => :display_autocomplete

Customer Model

def display_autocomplete
   self.firstname + ' ' + self.lastname
end

Error:

ActiveModel::MissingAttributeError (missing attribute: firstname):

Answer 1

You need to get the extra data, like so:

autocomplete :customer, :lastname, :display_value => :display_autocomplete, :extra_data => [:firstname, :lastname]
