Rails acts like a null renter in a model on Heroku

I am using gem 'acts_as_tenant'

Rails 3 in my application.

I have set the tenant to a domain based app controller:

  set_current_tenant_by_subdomain(:tenant, :subdomain)

      

        
        
        
      

    

I have some code in a work order model that needs to use current_tenant:

class Workorder < ActiveRecord::Base
acts_as_tenant(:tenant)

if ActsAsTenant.current_tenant.data.present?
  ActsAsTenant.current_tenant.data.each do |key, value|
    ransacker key do |parent|
      Arel::Nodes::InfixOperation.new('->', parent.table[:data], key)
    end
  end
end

      

        
        
        
      

    

On my local Mac, this works great. But, when I boot into Heroku, I get this error:

Sep 17 11:25:38 ndeavor-staging app/web.1:  /app/app/models/workorder.rb:8:in `<class:Workorder>': undefined method `data' for nil:NilClass (NoMethodError) 

      

        
        
        
      

    

So it ActsAsTenant.current_tenant

is nil (on Heroku).

Why is this?

Thanks for the help!

Update1

The same model ActsAsTenant.current_tenant

uses where

stmt without issue:

  if ActsAsTenant.current_tenant.data != nil
    ActsAsTenant.current_tenant.data.each do |key, value|
      ransacker key do |parent|
        Arel::Nodes::InfixOperation.new('->', parent.table[:data], key)
      end
    end
  end

  def self.woclosed
    where("wostatus_id = ?", ActsAsTenant.current_tenant.workorder_closed).where(:archive => false)
  end

      

        
        
        
      

    

UPDATE2

I tried to move the code to the app controller, but that doesn't even work locally:

class ApplicationController < ActionController::Base

set_current_tenant_by_subdomain(:tenant, :subdomain)

if current_tenant.data.present?
  current_tenant.data.each do |key, value|
    ransacker key do |parent|
      Arel::Nodes::InfixOperation.new('->', parent.table[:data], key)
    end
  end
end

      

        
        
        
      

    

But I am getting:

 NameError: undefined local variable or method `current_tenant' for ApplicationController:Class

      

        
        
        
      

    

Update3

I tried a different approach by looking at Subdomain URL renter. The search code works fine in the view, but it was not in the model.

ct = Tenant.where(subdomain: request.subdomain).first
  if ct.data.present?
    ct.data.each do |key, value|
      ransacker key do |parent|
        Arel::Nodes::InfixOperation.new('->', parent.table[:data], key)
      end
    end
 end
