Initializing form for One to One association - Rails

In today's lecture, we will focus on implementing a form to configure notification settings for users. We'll start by creating the form and controller at a basic level. Through this, you'll learn how to use a single form to handle a one-to-one association, managing both create and update actions. Specifically, we'll use the form to create a new notification setting if none exists for the user, and to update the settings if a record is already present. Additionally, this session will cover how to build non-resource forms in Rails. Be sure to watch the entire lecture for a thorough understanding.
