![]() ![]() ![]() However, the downside is that it is not as easy to write because you need to write raw SQL the code might be uglier and harder to maintain. Not only does the query builder protect against SQL injections, it's also much faster than Eloquent. When there is a lot of data or a lot of complicated joins, it's better to use the Laravel query builder and the DB facade. After all, it doesn't know your specific use case to make them more optimised. That's because it has to make unoptimised queries. However, it is slower than a query builder, so it should be used on a limited amount of data. It also helps protect against SQL injections - but be careful bad code can still be susceptible to this vulnerability. So what is the difference between these two, and when do you use them?Įloquent is good because it has simple object-oriented syntax, you don't need to know SQL very well to use it, the code is more readable and maintainable, it does a lot of extra things (eager/lazy loading), validations, and it's great when working with relationships between tables. In Laravel, we use Eloquent, but we can also use the query builder. Now that we know what Eloquent is, what Active Record is, and what the alternative to Active Record is, we can move on. We have to write it all manually it does not know any methods you might be familiar with from Eloquent, such as save(), delete(). ![]() UserMapper is a plain PHP class where we write the raw SQL code to communicate with the database, validate data, etc. We can have an User entity (resource) and then create UserMapper class to map this entity to a table. That means that the resource model knows nothing about the database. It is the middle layer, a buffer that filters and modifies retrieved data before reaching the resource. The difference between Data Mapper and Active record is that Data Mapper completely separates the domain from the application's persistence layer (database). It connects the application to the database using Object Oriented principles, which means you can write object-oriented code throughout the application.Īn alternative to Active Record is the Data Mapper. This layer sits between the database and the application. Every row in the table is an instance of that class, so every time a new class instance is created, a row is created every time an instance is deleted, a row is deleted.Īctive record is an ORM - Object Relational mapper. The database table (or view) is wrapped into a class ( User::class()). The Active Record pattern is an architectural pattern used to access data in a database. But if you are anything like me, you might wonder what the Active Record pattern is and what the alternatives are. You might even know that Eloquent implements the Active Record pattern. But have you ever wondered what Eloquent actually is? Other than retrieving and manipulating data saved in a database? ![]() The above is shown when I manually type the method name.If you work with Laravel, you probably work with Eloquent. These screenshots show 2 signatures: one from each mixin class. Use Illuminate\Database\Query\Builder as QueryBuilder Or like this (which is better if you need to use such class later in the code): use Illuminate\Database\Eloquent\Builder as EloquentBuilder but it's much less work and works good enough for my needs. May not be the best solution - not as good as listing specific return types for each method. Must be some issue in Laravel IDE Helper code.Īnyway: I normally just add these to eloquent model classes ( you may leave only the needed class). Having such a line there on your screenshot dos not make sense to me sine User is already a child class of Eloquent\Model class. What is Eloquent in " \Eloquent" line?įrom what I know \Eloquent resolves to " class Eloquent extends \Illuminate\Database\Eloquent\Model" (declared in the _ide_helper.php that Laravel IDE Helper generates). ![]()
