Eloquent Relationships Deep Dive

Learn how to set up and enforce one-to-one relationships using Eloquent. We'll walk through the database constraints, model definitions, default values, and how to work with related data efficiently.

In this episode, we explore Eloquent's one-to-many relationships using a practical example where each user can have many tasks. You'll learn how to set up the database schema, define Eloquent relationships, seed related data, query and eager load tasks—including how to filter eager-loaded relationships for more precise results.

Learn how to manage many-to-many relationships using Eloquent and pivot tables. We'll explore belongsToMany, pivot data, and how a custom pivot model can bring structure and logic to your relationship layer.

In this episode, you'll learn how Eloquent's hasManyThrough relationship lets you access deeply related data through an intermediate model. We'll walk through a practical example and show how it simplifies complex queries into a single, expressive relationship.

Learn how to set up and use polymorphic relationships, where a single model can belong to multiple other models using one database table. This episode covers both one-to-one (morphOne) and one-to-many (morphMany) examples with practical relationships like descriptions and notes.

This episode covers how to associate a single model, like Tag, with multiple other models using a single polymorphic pivot table. You'll learn how to define and use morphToMany and morphedByMany relationships to build flexible features like tagging across your application.

Learn how to optimize your Eloquent queries by using eager loading techniques. This episode covers constrained eager loading, lazy eager loading, counting related models, and running aggregate queries like withSum and withAvg.

Solve the N+1 problem forever while also taking advantage of Eloquent's lazy-loading feature.
