How to Get Username from Blog Post in Laravel

When working with Laravel and trying to display the username alongside a guide, you might encounter some errors that can be quite frustrating. One common issue arises when the relationship between the users and posts tables isn't set up correctly. In this guide, we will delve into how to effectively retrieve the username linked to a guide using Eloquent relationships.

This indicates that Laravel is trying to find a post_id column in the users table, which likely doesn’t exist. This happens due to a misconfigured relationship in your Eloquent models.

Understanding Eloquent Relationships

In Laravel, Eloquent ORM is used to define relationships between models. For our scenario:

User can have many posts.

Each Post belongs to one User.

Let’s explore how we can correctly define these relationships and resolve the issue.

The Solution

To successfully retrieve a username from a guide, follow these steps to set up your Eloquent relationships correctly.

Step 1: Define the Relationships in the User Model
