Larvel firstorcreate json compare7/15/2023 ![]() ![]() You are processing new applications and want to ensure there are no duplicates. ![]() firstOrNew is therefor very similar to firstOrCreate except data bas not been persisted yet. Models returned by ` firstOrNew` has not yet been persisted to the database and you will need to call save manually to persist it. If you’re interested in updating existing records, use ` updateOrCreate`. If you’re working with new records, use ` firstOrCreate`. Update or Create is when there might be an existing record, and you want to rather just update the existing one (or create a new one if an update wasn’t possible). Difference between firstOrCreate and updateOrCreateįirst or Create is when there are no records and you want to create one. I’ll leave this article here for the quick take, but if you want to rather learn from a master following this link: It tries to find a model matching the attributes you pass in the first parameter. This article attempts to explain the difference and provides some use cases. The firstOrCreate method is very similar to the firstOrNew method. There are two ways to create a record if not exist in laravel. To compound matters, the query builder has it’s own method, called updateOrInsert. The three methods are firstOrCreate, firstOrNew, and updateOrCreate. Since the specified book has been deleted and no longer available, we set the HTTP status code of the response returned to 204.Eloquent has three powerful methods if you want to work with existing data. Lastly, the destroy() method deletes a specified book from the database. In general, collections are immutable, meaning every Collection method returns an entirely new Collection instance. Otherwise we update the book with the new details and return a book resource with the updated details. As you can see, the Collection class allows you to chain its methods to perform fluent mapping and reducing of the underlying array. If the user is not the owner of the book, we return an appropriate error message and set the HTTP status code to 403. The update() method first checks to make sure the user trying to update a book is the owner of the book. The show() method accepts a Book model (we are using route model binding here) and simply returns a book resource based on the specified book. Then we return a book resource based on the newly created book. The store() method creates a new book with the ID of the currently authenticated user along with the details of the book, and persists it to the database. We’ll start by creating the Book model: php artisan make:model Book -m Next, let’s open the migration file generated for the Book model and update the up () method as below: database/migrations/TIMESTAMPcreatebookstable. The index() method fetches and returns a list of the books that have been added. STEP 1: Create models and migrations The book reviews API will have three models: User, Book and Rating. Once that is created, let’s open it and update the toArray() method as below: user2 User::firstOrCreate ( 'email' > '') // the below will dump out true because this user was created // in the current request lifecycle vardump (user2->wasRecentl圜reated) Share Follow edited at 18:33 Chuck Le Butt 47.2k 62 201 287 answered at 15:48 Thomas Kim 15. By default, resources will be placed in the app/Http/Resources directory of our application. We’ll make use of the artisan command make:resource to generate a new book resource class. Unlike when you use the resource() method, which will in addition to generating API specific routes, also generate create and edit routes, which aren’t needed when building an API.īefore we move on to create the BooksController, let’s create a book resource class. When building APIs with Laravel, it is recommended to use the apiResource() method while defining resourceful routes, this will generate only API specific routes ( index, store, show, update and destroy). For instance, /books/53/ratings will be used to rate the book with the ID of 53. make() The static make method creates a new collection instance. Refer to the documentation on extending collections for more information. Since we are building an API, we make use of apiResource() to generate API only routes.Īlso, we define a route that will be used to rate a specified book. macro() The static macro method allows you to add methods to the Collection class at run time.
