In this lesson of our Laravel 13 Full Course, we are breaking down the simplest but highly essential database connection: the One-to-One Relationship.
A One-to-One relationship occurs when a single record in one database table belongs exclusively to a single record in another table. Think of a User who has exactly one Profile, or a Company that has exactly one Setting configuration. In this tutorial, we will write our database migrations using foreignIdFor() combined with the critical .unique() constraint to ensure data integrity at the database layer.
Next, we will head into our Eloquent models to map out the connection using PHP 8.3 type-hinted methods:
The hasOne relationship on the parent model.
The belongsTo inverse relationship on the child model.
We will also cover a vital production trick: using the withDefault() method to prevent your application from throwing a "Trying to get property of non-object" error if a related record is missing!
