Learnhub: A collaboration app for innovative schools

Add the migration:

bin/rails generate migration add_completed_at_to_todo_items

Add this to the (db) migration:

class AddCompletedAtToTodoItems < ActiveRecord::Migration
  def change
  	add_column :todo_items :completed_at, :datetime
  end
end

Run:

bin/rake db:migrate

And for the tests as well:

bin/rake db:migrate RAILS_ENV=test

We create a new file called complete_spec.rb under >spec >todo_items:

Now we need to add a route and a controller action.

Let's start with the route for marking a todo item complete:
* When we want to update something, we use the patch http.

resources :todo_lists do
  resources :todo_items do
    member do
      patch :mark_complete
    end
  end
end

Now we add the "Complete" option to our views (notice we need to add the "patch" method:

<%= link_to "Mark Complete", complete_todo_list_todo_item_path(todo_item), method: :patch

Now we need to go to the Controller:

def complete
    @todo_item = @todo_list.todo_items.find(params[:id])
    @todo_item.update_attribute(:completed_at, Time.now)
    redirect_to todo_list_todo_items_path, notice: "Todo item
    marked as complete."
  end
