When retrieving records from the database, sometimes we may require fetching those categories which has product, and this can be achieved by simply. Let's suppose: One to Many relationships between category and products. One to Many relationships between product and feedbacks. $categories = Category::has('products')->get(); But what if we are supposed to retrieve those categories that has product with feedbacks.
Note: You should method named products to define hasMany() relation for product in Category Model and feedbacks method to define hasMany() relation for feedbacks.
