I have been using Laravel for about 2 months. And I'm just wondered about how to define models in the proper way.
For example, I define model's method in this way.
public static get_book_static($id){
return Book::where($id)->first();
}
public get_book($id){
return Book::where($id)->first();
}
In models, I defined the methods both in static and not.
I want to know that which one is the better way to use, because Laravel seems to use a lot of static methods out there.
There isn't a better way. Static is necessary in some cases and in some cases it is not. If you need to call a method statically with instantiating a model object first, then it needs to be static. For example, in your controller:
$myBook = Book::find($id); // find() is built into Laravel's ORM
$myBook->doSomething(); // doSomething() is a custom non-static function that you added to your Book model.
$anotherBook = Book::findSomeOtherType(); // findSomeOtherType() is a custom static function you added to the Book model.
Also, it looks like you are doing extra, unnecessary work. The Book object IS your model:
Book::where($id)->first();
is the same as
Book::find($id);
You shouldn't have to create any sort of public get_book($id) function. Just use Book::find($id) directly in your controller.
