Mastering Sorting by Relationship Columns in Laravel Eloquent

Laravel Eloquent ORM provides a clean and fluent way to interact with databases using an elegant syntax. One common need when working with Eloquent is sorting data based on columns from related tables. This can be tricky, but with the right approach, it’s straightforward to implement. In this post, we will dive into sorting by relationship columns in Laravel using Eloquent ORM.

Understanding Relationships in Laravel

Before getting into sorting, it’s essential to understand the types of relationships supported by Laravel Eloquent:

One-To-One: A single model is related to a single model of another type.

One-To-Many: A single model is related to one or more models of another type.

Many-To-Many: Multiple models are related to multiple models of another type.

Has-Many-Through: Provides a shortcut for accessing distant relations via an intermediate model.

Polymorphic Relationships: Models share a polymorphic relationship, allowing a model to belong to more than one type of model on a single association.

Sorting by Relationship Columns

Let's say we have two models: Post and User, where each Post belongs to a User. To sort Post records by the name of the related User, follow these steps:

Step 1: Define the Relationship in the Models

First, ensure the relationships are defined in your models.

Step 3: Using Eloquent Relationships

Alternatively, if you prefer to stay within Eloquent's ORM methods without directly using join, you can leverage the with method combined with orderBy:

Whether you choose to use join queries or Eloquent relationships, Laravel provides versatile methods for effective data querying and sorting. With these techniques, you can handle complex data needs effortlessly in your Laravel applications.
