Reusing Query Parts in Laravel's Eloquent Builder: A How-To Guide

Are you tired of repeating lengthy sections of your Eloquent queries in Laravel? If you’re like many developers, you want to write cleaner, more maintainable code. The good news is that Laravel offers robust solutions to accomplish this, particularly from version 8 onwards. Let’s dive into how you can efficiently reuse parts of your Eloquent builder queries.

The Problem: Redundant Query Parts

In many applications, there arise situations where multiple queries share a long, repetitive section of code. For instance, consider the following toy queries:

Notice how both queries are identical up to the where clause? This duplication can lead to increased maintenance overhead and reduced readability.

You might wish for a way to encapsulate this repetition in a shared variable or function, allowing for cleaner query definitions like this:

The Solution: Cloning in Laravel Eloquent Builder

Laravel 8+ Approach

If you're working with Laravel version 8 or later, you have a simple and effective way to reuse your query parts. You can leverage the clone method to create a duplicate of the shared query. This allows you to modify it without affecting the original query structure. Here’s how you can do it:

Define the Shared Query:
Create your joint query as a variable.

Laravel Before Version 8

If you're using a version prior to Laravel 8, the approach is quite similar but requires a slightly different syntax for cloning. Here’s how you can do it:

Define and Clone:
Start by defining the shared query and use PHP's clone keyword.

Conclusion

By effectively reusing parts of your Eloquent queries, you not only streamline your code but also enhance its maintainability. The clone method in Laravel makes this very simple and intuitive, especially in its latest versions. Take advantage of this practice to write cleaner, more efficient code that is easier to understand and modify in the long run.

Happy coding with Laravel!
