Eloquent find has many7/2/2023 Taking things up a notch, we are also able to load counts on related models when we are eager loading them. On Laravel, using eloquent, joining the posts table would look something like this. $sandwiches->first()->salads_count // number of related salads Post -> hasMany -> Comment Post -> morphMany -> Image. $sandwiches = Sandwich::orderByFreshness()->withCount()->get() The withCount() method also allows you to get multiple values at once by passing in an array instead of a string. $sandwiches->first()->fillings_count // number of related fillings $sandwiches = Sandwich::orderByFreshness()->withCount('fillings')->get() The number of relationships will be stored on the model as an attribute with the format "_count". To add relationship counts to the hydrated models we use the withCount($relationship) method. Luckily for us the query builder is able to retrieve relationship counts while it is loading out models from the database, and does not have to hit the database a second time to do it. Every time we hit the database we are impacting the performance of our app, so the fewer hits we make, the better. Using the Eloquent model, you can perform many database-related functionalities such as creating, updating, reading, and deleting records. The model helps you interact and communicate with a specific database schema. We use the query builder to retrieve our eloquent records and hydrate our models. Is it possible to use eloquent to retrieve just the first match in a one to many relationship What do I mean, well, let me explain. Laravel Model is a single PHP object that represents a database schema in a database. If you are pretty comfortable with the first two options you can skip to the eloquent collection content. We are going to take a quick look at all of them, and when you would use one over the other. The Laravel team created Eloquent to ease the interaction and communication with databases and provides an easy-to-use way to address all database and development-related problems. 2 have been around for a while, but there is a new kid on the block: Eloquent is Laravel’s Object Relational Mapper (ORM) with an elegant, beautiful and efficient way of interacting and managing databases. Laravel offers a number of ways to retrieve relationship counts. In this scenario you do not want to load all of the related models into memory to count them, we want our database to do the heavy lifting for us. Anyone thanks for an answer Last updated 10 months ago. It is often useful to show the number of related models a given instance has, but not actually need any specific information about the related models, just how many exist.
