In this quick Laravel tips tutorial i will show you how to set foreign key in laravel migration. I will show you the best way that you can write foreign key in your relationship table. Today I would like to write about a quick tip to use when writing foreign keys in Laravel 7 and Laravel 8.
This tips will help you write shorter migrations and make your code more readable. For our tutorial, I am going to use the
user_id which is very common but this can be applied to any foreign key.
In the past we would write something like this:
$table->unsignedBigInteger('user_id') ->index(); $table->foreign('user_id') ->references('id') ->on('users') ->onDelete('cascade');
Look, pretty verbose right?
The good news Dear reader is that we can write this same functionality like this:
$table->foreignId('user_id') ->index() ->constrained() ->onDelete('cascade');
I think it is much nicer and easier to read, I hope you enjoyed this tip.
