In this example we will see laravel 8 one to one relationship example also you can use one to one relationship in laravel 6 and laravel 7. One to one relationship is a very basic type of database relationship. You have one table with primary key that references the id of the other table. For one to one relationship use
hasOne and belongsTo method in model for access each other model.
Also we will create migration with foreign key, retrieve records using model, insert new records, update records etc.
We will create User and Phone table.
User model might be associated with one
Phone model. To define this relationship, we will place a
phone method on the
User model. The
phone method should call the
hasOne method and return its result.
