get table id in migration file (laravel 5.8) - php

Question

I want id of the users. (in migrations to use the id in if statements and add different default values to new table column)
I tried to use getColumns()->id but it showing some warning in ide(Field id not found).
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class AddUserRoles extends Migration
{
public function up()
{
Schema::table('users', function (Blueprint $table) {
$ID = $table->getColumns()->id;
if($ID == '1') {
$table->string('role')->default('admin');
} else {
$table->string('role')->default('member');
});
}
public function down()
{
Schema::table...
.....
}
}
EDIT: this the users table
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
my purpose is to use id for setting different default roles to the users table.

You can't read users while creating the users table, since you does not have any users yet.
Create this table for users:
class CreateUsersTable extends Migration
{
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->string('role')->nullable();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
}
Then, you can add users and check the id to assign them a role:
$user = new User();
$user->name = 'name';
$user->email = 'email#example.com';
$user->password = Hash::make("123456");
$user->save();
if ($user->id === $someId) {
$user->role = 'some_role';
$user->save();
}
Hope it helps.
