Associating Entities and Handler Functions with the User

Till now, all notes were visible to all users. We will add a foreign key user_id to the notes table. The column user_id stores the Id of the user to whom the note belongs.

Then, we will change the handler functions to get the user identifier from the session to carry out the dtabase operations in the user’s context.

Associating notes with users

To associate notes with users, we need to do the following:

1. Create a new migration that adds the foreign key user_id to the notes table.

2. Alter the Note model to add user ID to the model structure and methods.

Creating a migration

We begin by creating a new migration to add user_id to the notes table.
