Ruby Undefined Method (in model)

Question

I am getting a NoMethodError when trying to call my "not_coworker_friend" or "coworker_friend" method. I am working in Ruby MVC. This is my current code, As written it does not produce any errors:

class EmergencyTrip < ActiveRecord::Base

belongs_to :user

has_attached_file :receipt
validates_attachment_presence :receipt

validates_presence_of :trip_cost, :if => :not_coworker_friend
validates_presence_of  :phone_of_person, :if => :coworker_friend

def not_coworker_friend
  (self.ride_home_service == "co-worker/friend") ? false : true
end

def coworker_friend
  (self.ride_home_service == "co-worker/friend") ? true : false
end

end

My objective is to only validate the receipt if "not_coworker_friend" == true.

Lines 5 & 6 should be:

...
has_attached_file :receipt, :if => :not_coworker_friend
validates_attachment_presence :receipt, :if => :not_coworker_friend
...

Adding the ":if => not_coworker_friend" to those lines generates a NoMethodError (undefined method `call' for :not_coworker_friend:Symbol):, even though there is no error thrown for lines 8 & 9. Why does this only selectively throw an error? And how can I correct this?

I changed so the method was defined before use but this did not work. There is no error for when it is called on lines 8 & 9 regardless, so it has to be defined. — objectively C

Should work like this. Maybe reload console? but please read up on boolean: en.wikipedia.org/wiki/Boolean_data_type — Fallenhero

@Fallenhero I have reloaded my console and restarted my whole application many times and rebuilt and clean. Of course it should work like this... but it does not so I am asking why — objectively C

try this:

class EmergencyTrip < ActiveRecord::Base

    belongs_to :user

    has_attached_file :receipt, :if => Proc.new{|f| f.ride_home_service != "co-worker/friend"}
    validates_attachment_presence :receipt, :if => Proc.new{|f| f.ride_home_service != "co-worker/friend"}
end
