Error on shopping cart and users after deleting a store

Yes, if you delete data that is in use, you will break things.

There are several open issues about this in the issue queue. To be solved at a later date.

Go to devel/php and delete the cart order using normal Entity API methods ($order = Order::load($your_id); $order->delete())

I would not recommend it.

Hi,

I have an doubt. I got the same error when I am after deleting a store. I removed the order items. but, I can't able to remove the orders.
"There is content for the entity type: Order. Remove orders." How can I fix this issue?
I need to remove the existing orders

Thanks in Advance.

I faced this error on Drupal 8.5.x with commerce order module and resolved this error.

Here's what worked for me.
0. Check there is at least one store created (If you have accidentally deleted an existing one)
1. Temporarily apply the patch
2. Go to Extend > Uninstall
3. Find 'Commerce Order' and click these two (Make sure the patch is applied, or it will throw up the same errors)
3a. 'Remove orders'
3b. 'Remove order items'
4. Revert the patch

It would be really helpful if people mentioned the status of this patch, if it will be included in future updates or not.

Hi @mesh,

Nothing is working. I have applied patch but same error displaying.
The website encountered an unexpected error. Please try again later.
Error: Call to undefined method Drupal\commerce_store\Entity\Store::getCustomer() in Drupal\commerce_order\OrderRefresh->refresh() (line 139 of modules\contrib\commerce\modules\order\src\OrderRefresh.php).

Can confirm #7 worked for me when I deleted a store that still had somewhere some data in a users cart.

Delete the problem cart order from the database fixed my problem. I had an error when I tried to remove them from the uninstall/module list

Clearing carts works for me:

DELETE FROM `commerce_order` WHERE `cart` = 1

I had the same problem after removing stores from my products, what I did to fix it was the following:

1. Create a new store and see the store id in the database (in the commerce_estore table):

SELECT * FROM commerce_store;

2. Change the "store_id" field of all orders to the store id we have created (you should be careful if you already have orders with existing stores -> filter correctly with the where clause of the query):

UPDATE commerce_order SET store_id=7 WHERE store_id NOT IN (8,9)
(In the example i was deleted stores with id 1 to 6, and i have already orders with stores 7,8,9)

3. In theory, the add to cart button and similar functions affected should be working ...

This is not "the solution", but it could help ... I'm quite paranoid about running DELETE queries (in ignorance) in the database hehe
