Relations¶

Relationship types are read from the relation method's declared return type, so that type has to carry its generic parameters. The class the relation points at is taken from there rather than from the hasMany(Post::class) argument, which means an undocumented relation resolves to the base relation class and the related model is lost.

/** @return BelongsTo<User, $this> */
public function user(): BelongsTo
{
    return $this->belongsTo(User::class);
}

/** @return HasMany<Post, $this> */
public function posts(): HasMany
{
    return $this->hasMany(Post::class);
}
