I've defined a virtual column and when I try to set it's label I get
"undefined method `label=' for nil:NilClass"
Here is my model:
class FundingApplication < ActiveRecord::Base
acts_as_paranoid
belongs_to :grant_category
belongs_to :application_type
has_many :people, :order => :person_type_id
has_one :business_manager, :conditions => ["person_type_id = ?",
PersonType.business_manager], :class_name => 'Person'
has_one :optional_contact, :conditions => ["person_type_id = ?",
PersonType.optional_contact], :class_name => 'Person'
has_many :co_investigators, :conditions => ["person_type_id = ?",
PersonType.co_investigator], :class_name => 'Person'
has_one :principal_investigator, :conditions => ["person_type_id
= ?", PersonType.principal_investigator], :class_name => 'Person'
mount_uploader :abstract, AttachmentUploader
mount_uploader :pre_proposal, AttachmentUploader
validates_presence_of :project_title, :amount_requested, :grant_category_id,
:application_type, :abstract, :pre_proposal

validates_inclusion_of :will_study_require_irb_approval,
:will_study_require_iacuc_approval, :has_child_health_component_to_research, :in

validates_length_of :worked_with_co_investigator_explaination, :maximum
=> 250, :tokenizer => lambda {|str| str.scan(/\w+/)}, :too_long => "is
too long (maximum is {{count}} words)"
accepts_nested_attributes_for :people
def self.yes_no
{
1 => 'Yes',
0 => 'No',
true => 'Yes',
false => 'No'
}
end
def pi_first_name
principal_investigator.first_name
end
def pi_last_name
principal_investigator.last_name
end
end
and here is the AS controller:
class Admin::PilotPreApplicationsController < ApplicationController
include ApplicationDownloader
layout 'admin'
active_scaffold :pilot_pre_application do |config|
config.label = "Pilot Pre Applications"
config.create.link = false

end
end
The error happens on line 39 of the controller
Here is the error:
