This example is not my real app, but it's modeled pretty closely to it.

My mom schedules a couple hundred employees at a local warehouse. In their system, a worker can earn "points" for being late or missing shifts. Here we have a sort of summary screen for my mom, who may need to follow up with new employees or discipline employees with concerning levels of points.

Questions that arise as I code something like this:

• Which objects deserve presenters?

require 'test_helper'
require 'clearance/testing'

class EmployeesControllerTest < ActionController::TestCase
  
  test "an ASM can not create a user" do
    sign_in
    assert_raise CanCan::AccessDenied do
      post :create, :employee => { :name => 'Feed Store' }
    end

    orders[item_code][year] = {}
    year_orders.group_by(&:month).each do |month, month_orders|
      orders[item_code][year][month] = month_orders.first.quantity
    end
    orders[item_code][year]["total"] = orders[item_code][year].values.map(&:to_f).sum
  end

class Tag
  has_many :taggings
  named_scope :important, :include => { :taggings => :important }
end

class Tagging
  belongs_to :tag
  belongs_to :posts
  
  # uses a string 'flag' column but could be changed to a boolean important
