Overviews of Laravel firstorcreateLaravel is an object-relational mapper which makes it interesting to communicate with the database. It works to retrieve records from the table in the database and also enables the user to update, insert, and delete records from the database or table. The firstorcreate method in Laravel is used to find the database record with the help of value pairs and given columns. If the user is unable to find the model in the database, the record will get inserted along with the attributes which result from appending the first array argument with the alternative argument in the second array.

firstOr method is used at the time of source-driving and is used to retrieve the first model from the executed query or if any matching model is not found, it is used to make a call and a callback should be passed.

$ user = user:: updateorcreate() ( ); Laravel firstorcreate Model Methodwhen working on an application, the user has to search a table for instance and if it doesn’t exist he can create a new one and save it in the table. similar to firstorcreate(), there is another option firstornew which retains the first instance if it exists or is created as a new instance without saving it in the actual table.
Firstorcreate is used to locate the first model which matches the suitable constraints or build a new instance if any values don’t have the matching constraints. It fetches the matching of the first record and attributes or it creates a new suitable parameter to fit in the table.
Then it searches for the model with a suitable parameter which is passed as the first parameter.
If no matching model is found, it develops and saves it as a new model after implementing the value of the key-pair passed like the second parameter.
$ uuid = request ('uuid'); if ($device === null) { } ConclusionThe Laravel used to provide an instant option which firstorcreate() which performs both functions like creating new and searching and also return the instances. So the user can prefer this model as a simple choice.
