Courses Plus Student 18,036 PointsCode repeated inside the TodoItems Controller in the Teacher's Notes
In the Teacher's Notes of the "Cleaning Up Our Code" video, the code
before_action :find_todo_list
is written twice on the same line in this code
class TodoItemsController < ApplicationController
before_action :find_todo_list before_action :find_todo_list
...
def find_todo_list
@todo_list = TodoList.find(params[:todo_list_id])
end
Is that an error or not? And what does the code do?

5,396 PointsIt shouldn't be written twice. It's just another problem among a litany of others in this course. So much for cleaning it up, eh? LOL
before_action basically means what it says: before any method (or action) in the Items Controller, it executes the method find_todo_list
first. So if it runs the create
method, it first runs the find_todo_list
method first. If it runs the update
method, it runs find_todo_list
first as well. So instead of repeating the same line of code it's just said once, with the same result.
