Mahmoud Zalt: Eloquent Relationships Cheat Sheet
Mahmoud Zalt has a recent post to his Medium.com site that shares a cheat sheet for Eloquent relationships you can use with the Eloquent database layer in a Laravel application.
He goes through each of the relationship types and provides both a diagram showing the relationship and some sample code to make it work:
- One to One
- One to Many
- Polymorphic One to Many Relationship
- Many to Many Relationship
- Polymorphic Many to Many Relationship
The post ends with a combined table of all of the relationships, how they connect with the other models, the number of tables involved and how to set values to a related model.
