Yesterday, I came across an interesting topic in a pre-written Laravel project.
When the programmer takes a list or a record from a table with eloquent, in addition to the columns of that table, he also needs some additional properties to generate a record using the values ​​of the columns of that table. For example, suppose we store the user’s date of birth in our table, and in addition to the date of birth, we also need to return the user’s age.
Now, in this project, there was also a requirement, a mapper had been added to the list taken from the database and those additional properties had been created for each record. Well, this makes us not follow the principle of DRY (Don’t Repeat Yourself) and because of creating a simple property, we have to write a loop inside the places where we have a list, and of course it slows down the service we wrote. Now, the solution that Laravel has considered is the append feature inside the Model. That is, in the append array, we define the additional keys that must be returned, and in the method we specify the name format get+{appendName}+Attribute so that the added property will be created in the form. With this, every time a list or a specific record is received from our table through Model, appends are automatically included as keys among properties.
