Testing controller 'helper' type methods

I have a couple methods defined in controllers that I call in one of the controller actions.

Example from SearchController:

I've been testing these methods by actually making a request. That can't be the most efficient way to test them. I can't exactly call ApplicationController.assigns_session_tags and then test the result...

themoxman

resources :collections do
  resources :notes, :tags
end

def new
  @ticket = @project.tickets.build
end
# is basically the same as 
def new
  @ticket = Ticket.new(project_id: @project.id)

Solution??

Wow. So I instantiate @tag (a new tag object) for simple_form to use. The problem is that this new tag has no id yet. And this new tag gets added to @tag_list. So when I iterate over @tag_list to create the 'edit' links, eventually it hits a tag with no id and throws the error. Least I think this is what's happening.

pry output:

Pretty much everything in a Ruby program is some type of 'Object'.

If you haven't already, you'll soon here the phrase 'Object Oriented Programming' thrown around. You'll also hear the abbreviations OO or OOP.

With OOP we create programs and try to model them after the real world. 'Objects' allow us to encapsulate real-world ideas and then manipulate them and provide the user of our program with some output. So the typical flow of any object-oriented program is as follows:

Input - some type of data or value

Program - takes the input and manipulates it

class Transaction

  attr_reader :name, :description, :amount, :purchase_date

  def initialize(name, description, amount, purchase_date)
    @name = name
    @description = description
    @amount = amount
    @purchase_date = purchase_date
  end

Annoying Random Spec Failure

No rhyme or reason as to failure. Just depends on the order of the specs.
