Can't set label for virtual column #726

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
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_numericality_of :amount_requested, :greater_than => 0,
:less_than_or_equal_to => 50000
  validates_inclusion_of :will_study_require_irb_approval,
:will_study_require_iacuc_approval,
:has_child_health_component_to_research, :in => [true, false]

  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
    config.update.multipart = true
    #config.list.always_show_search = true
    #config.actions.swap :search, :live_search

    config.action_links.add "Download", :controller =>
'pilot_pre_applications', :action => 'download', :type => :record, :inline
=> false

    config.list.columns = [ :pi_first_name, :project_title,
:amount_requested, :grant_category, :created_at ]

    config.show.columns = [ :project_title, :grant_category,
:amount_requested, :will_study_require_irb_approval, :has_irb_approval,
                           :will_study_require_iacuc_approval,
:has_iacuc_approval, :worked_with_co_investigator_explaination,
:has_child_health_component_to_research,
                           :principal_investigator, :business_manager,
:optional_contact, :co_investigators, :abstract, :pre_proposal,
                           :created_at, :updated_at ]

    config.update.columns = [ :project_title, :grant_category,
:amount_requested, :will_study_require_irb_approval, :has_irb_approval,
                           :will_study_require_iacuc_approval,
:has_iacuc_approval, :worked_with_co_investigator_explaination,
:has_child_health_component_to_research,
                           :abstract, :pre_proposal, :people,
                           :created_at, :updated_at ]

    config.columns.each { |column| column.label = column.label.titleize }

    config.columns[:people].show_blank_record = false
    config.columns[:grant_category].clear_link

    config.columns[:will_study_require_irb_approval].label = "Requires IRB
Approval?"
    config.columns[:will_study_require_iacuc_approval].label = "Requires
IACUC Approval?"
    config.columns[:has_irb_approval].label = "Has IRB Approval?"
    config.columns[:has_iacuc_approval].label = "Has IACUC Approval?"
    config.columns[:has_child_health_component_to_research].label = "Has
Child Health Component?"
    config.columns[:pi_first_name].label = "This"

    config.columns[:will_study_require_irb_approval].form_ui = :checkbox
    config.columns[:will_study_require_iacuc_approval].form_ui = :checkbox
    config.columns[:has_irb_approval].form_ui = :checkbox
    config.columns[:has_iacuc_approval].form_ui = :checkbox
    config.columns[:has_child_health_component_to_research].form_ui = :checkbox
    config.columns[:grant_category].form_ui = :select
    config.columns[:created_at].form_ui = :calendar_date_select
    config.columns[:updated_at].form_ui = :calendar_date_select

    config.columns[:created_at].label = "Submitted"
    config.columns[:updated_at].label = "Updated"
  end

end

The error happens on line 39 of the controller

Here is the error:

You must create the virtual column, adding to config.columns, before 
configuring it.
