How do you use the `belongsTo` relationship in Laravel?

How do you use the `belongsTo` relationship in Laravel?

Answer: In Laravel, the `belongsTo` relationship is used to define a one-to-one relationship where a model belongs to another model. To use it:

1. Define the relationship in the child model: Use the `belongsTo` method to specify the parent model.

“`php
class Comment extends Model
{
public function post()
{
return $this->belongsTo(Post::class);
}
}
“`

2. Set the foreign key: By default, Laravel expects the foreign key to be `post_id`. If the foreign key is different, you can specify it as the second parameter.

“`php
public function post()
{
return $this->belongsTo(Post::class, ‘custom_foreign_key’);
}
“`

3. Accessing the relationship: You can access the parent model from the child model using the relationship method.

“`php
$comment = Comment::find(1);
$post = $comment->post; // fetches the associated post
“`

4. Eager loading: To optimize queries, you can eager load the relationship.

“`php
$comments = Comment::with(‘post’)->get();
“`

This allows you to efficiently retrieve related data between models.
