Laravel change foreign key name

Laravel foreign key

Schema::table('posts', function (Blueprint $table) {
    $table->unsignedBigInteger('user_id');

    $table->foreign('user_id')->references('id')->on('users');
});
OR
Schema::table('posts', function (Blueprint $table) {
    $table->foreignId('user_id')->constrained();
});

Create foreign key laravel migration

Schema::table('posts', function (Blueprint $table) {
    $table->unsignedBigInteger('user_id');

    $table->foreign('user_id')->references('id')->on('users');
});

Laravel adding Foreign Key Constraints

$table->foreignId('user_id')
      ->constrained("users") <- // You don't need to specify table if it matched laravel naming conventions.
      ->onUpdate('cascade')
      ->onDelete('cascade');
