In this video, Justin demonstrates how to write a many-to-many relationship in Laravel, where multiple entries in the database relate to multiple other records elsewhere in the database.
- [Instructor] Our most complex relationship … is a many to many relationship. … In a many to many relationship, … we need to go from many records in one table … to many other records in another table. … These relationships are defined using a join table, … where you have a collection of records … that has a matching ID pairs from each other table. … This middle table acts then … to join those two other tables together. … This is a classic many to many relationship, … and we actually have one in our database … between bookings and user. … A user has many bookings, obviously, … because a user can have multiple bookings at a hotel, … and each booking is designed such that … multiple users could be associated … with each booking if need be. … Let's fill out the bookings model … and see this many to many relationship in action. … We'll open up the bookings model … at app, Booking.php. … Let's define first some of the relationships … that we've already previously seen. … We'll define a relationship from the booking to the room. …
