Create coupon code programmatically (in Magento 2.x)

I'm trying to port over tens of thousands of coupons from a custom e-commerce website into Magento 2.0.8 and I'm having a hard time getting it to work. These are simple coupons either fixed $ or % off of the carts subtotal. I have been unable to get it to save from the command line.

I have a command called coupons:migrate that I'm running this code in. This is what I have so far in my createCoupon method that accepts the current coupons row (looping over a CSV file):

protected function createCoupon($coupon) {
        $shoppingCartPriceRule = $this->objectManager->create('Magento\SalesRule\Model\Rule');


    return $shoppingCartPriceRule->save();


I'm currently getting this error from my database:

  SQLSTATE[HY000]: General error: 1205 Lock wait timeout exceeded; try restarting transaction, query was: INSERT INTO `magento_reward_salesrule` (`rule_id`,`points_delta`) VALUES (?, ?) ON DUPLICATE KEY UPDATE `points_delta` = VALUES

  SQLSTATE[HY000]: General error: 1205 Lock wait timeout exceeded; try restarting transaction

Any help would be greatly appreciated. I'm basically stuck now.


You can try below code:

protected $ruleFactory

public function __construct(\Magento\SalesRule\Model\RuleFactory $ruleFactory) {
    $this->rulesFactory = $ruleFactory }

$ruleData = [
            "name" => "Buy 3 tee shirts and get the 4th free",
            "description" => "Buy 3 tee shirts and get the 4th free",
            "from_date" => null,
            "to_date" => null,
            "uses_per_customer" => "0",
            "is_active" => "1",
            "stop_rules_processing" => "0",
            "is_advanced" => "1",
            "product_ids" => null,
            "sort_order" => "0",
            "simple_action" => "buy_x_get_y",
            "discount_amount" => "1.0000",
            "discount_qty" => null,
            "discount_step" => "3",
            "apply_to_shipping" => "0",
            "times_used" => "0",
            "is_rss" => "1",
            "coupon_type" => "NO_COUPON",
            "use_auto_generation" => "0",
            "uses_per_coupon" => "0",
            "simple_free_shipping" => "0",
            "customer_group_ids" => [0, 1, 2, 3],
            "website_ids" => [1],
            "coupon_code" => null,
            "store_labels" => [],
            "conditions_serialized" => '',
            "actions_serialized" => ''

$ruleModel = $this->ruleFactory->create();

Try code below

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$state = $objectManager->get('Magento\Framework\App\State');

$coupon['name'] = 'test';
$coupon['desc'] = 'Discount for Test';
$coupon['start'] = date('Y-m-d');
$coupon['end'] = '';
$coupon['max_redemptions'] = 1;
$coupon['discount_type'] = 'by_percent';
$coupon['discount_amount'] = 15;
$coupon['flag_is_free_shipping'] = 'no';
$coupon['redemptions'] = 1;
$coupon['code'] = 'test-1234'; //this code will normally be autogenetated but i am hard coding for testing purposes

$shoppingCartPriceRule = $objectManager->create('Magento\SalesRule\Model\Rule');

I don't try to test your code, however, seem that your code lines need to improve the performance. After saving the object model, we need to unset the data object:
