The problem

Initially asked at RORO but I will elaborate with an example.

What we need to do is the following:

• we list a set of items (let's say posts) and want to show a drop-down menu next to each one (quick example)
• when the drop-down arrow is clicked the menu is loaded from the server.

dnagir

class BackgroundWorkerStarter
  attr_reader :env

  def initialize(env)
    @env = env
  end

  def start!
    write_pid!(pid_file) if pid_file

dnagir

class CreditCard
  include ActiveAttr::Model
  attribute :number
  attribute :expiry
  attribute :cvn
  attribute :name

  validate :must_be_valid
  validates :number, :expiry, :cvn, :name, presence: true

# Example 1, not so cool (look at the 'less-than' and OR condition)

# plain AR:
Property.joins(:reservations).
  where(status: 'reserved').
  where("reservations.status = ? OR reservations.reservation_type = ?", 'active', 'offline').
  where(reservations: {reservation_fee_received: false}).
  where("reservations.fee_due_at < ?", DateTime.now)

# with squeel:

class CommentsController < ApplicationController

  def create
    @article = Article.find(params[:article_id])
    @comment = @article.comments.build(params[:comment])
    @comment.save # etc
  end

end
