Mastering Laravel 6 Eloquent Relationships for Multicategories

In web application development, organizing content hierarchically is often essential for usability and data management. When dealing with categories, subcategories, and posts in Laravel 6, you may encounter the challenge of displaying this data without redundancies. This guide will guide you through the solution to a common problem: how to structure your Eloquent relationships effectively to avoid repetition in listings of categories and posts.

Understanding the Problem

Imagine you have a system with three key database models:

Parent Categories

Subcategories

Posts

The hierarchy looks like this:

You have set up relationships in your models as follows:

The Subcategories model relates to Categories and Posts.

The Posts model relates to Subcategories.

While this setup is correct, rendering these relationships in a view can lead to repeated outputs. For example, if you have multiple posts under the same subcategory, your current implementation displays the category and subcategory multiple times instead of just once.

Proposed Solution

To solve this issue, we need to optimize the relationships, refine the controller logic, and adjust how data is presented in the view. Below is a step-by-step breakdown of how to achieve this.

Model Relationships

First, ensure that your Eloquent relationships in your models are robust. Here’s what they should look like:
