Can someone explain the difference between TodoList and todo_list, when you're trying to verify the existence of titles?

Question

Can someone explain why we're using TodoList and not todo_list (or todo_lists)?

it "displays an error when the todo list has no title" do
        expect(TodoList.count).to eq(0)

Any help is appreciated.

TodoList is the the name of the Model ( that inherits from ActiveRecord::Base ).

The Test starts expecting there are no Todo List checking TodoList.count.

Then it continue trying to add a new Todo list but without a title, so we want it returns an error and the TodoList.count still be 0. In fact, if the todolist does not have a title no records are saved in the database.

So why are we using "TodoList" instead of "todo_list"? I'm still confused. The app is named "odot", so I'm not sure where TodoList came from.

So "TodoList.count" is checking the entire class for an entry?

Yes it checks the TodoList table on the database. The TodoList is the class name for your model that was created when you wrote the command "rails generate scaffold todo_list ...." in the app/models/todo_list.rb
