The object that will be received will be the instance of the ‘Model’ and all the database fields that are available will be made available as attributes as that of the class. With the help of the ‘find’ method as seen in the above image when the user retrieves information, the user is bound to get an object if the record actually exists in the database. ‘Where’ uses the ‘get’ method in which you will get more than a single result as it does deep searching and responds with many similar kinds of data in response. Unlike ‘Where’ that helps you to get any valid database field, find is using only the primary key that is registered by default in the system to retrieve single data from the database. In the above image, id is ‘1’ and is having data records to be retrieved of the ‘kids’ section with the description as ‘items that are meant for kids’, The other details of time are represented as ‘null’ which means they are not available in the database with the help of Laravel Find. The above example will help us to understand the working of Laravel Find better. It also works on all supported database systems. Most of the database operations can be performed in the application that is customized and prepared. It also gives an interface to create and run the queries of the database. The query builder that is available in Laravel provides a lot of conveniences. This misunderstanding needs to be clarified in priority. One thing that any user will have to note is that Laravel find is not a query builder as it may look to be. Laravel Find is used to retrieve data with the help of primary keys that are available in Laravel. Most of the data in Laravel are auto-generated and they are self-coded as Laravel PHP helps in getting applications and websites ready faster with a lot of automated properties. With a load of too much data, it becomes difficult or even time-consuming to manually hunt for a specific set of records to work on.
Laravel find is capable of retrieving data from the database for the user when the user needs to obtain a concerned set of data from a larger database. The results that are obtained with the help of the ‘find’ method are always limited to the record that is available and the object is returned in the form of a result. The SQL statement that is equivalent is the ‘SELECT FROM categories in which the WHEREid = 1 LIMIT 1. ‘Find’ method makes use of the primary key id that generally works by filtering for any particular record with the simple id value of 1. $c->find (1) works by calling the ‘find’ method on the user’s instance variable, which is $c which helps in returning a single record for the user.
Laravel also expects the id to be an integer if you are using something other than an integer (such as a string) you need to set the incrementing property on your model to false.
If you have something set up like protected $primaryKey = foo_id the find() function will go through foo_id instead of id. If you have none set, it’s going to assume id. The find() method finds the Model by its $primaryKey property. When there is a need to retrieve any record with the help of the primary key use this code: $user = User::find (1)
