Okay, so after we've created the order and we have attached the variations,

00:05

we of course need to reduce the stock. So we're going to do this in a slightly inefficient way by going ahead and iterating through all of the contents, which means if we had 10 items now can't, we're going to go ahead and form 10 queries.

00:19

We'll clear this up a little bit later, but let's get this done for now. Once we've iterated through them for each of the variations, which we get into this closure here,

00:29

we are going to go ahead and access the stocks, and we're going to create a record, and remember this is going to be a negative record. So all we need to do for this is in the amount,

00:40

just subtract from zero. So we're just going to grab from that pivot table, the quantity, and that's pretty much it. So let's go ahead and try this out.

00:52

We just come over here. Remember, we're not clearing our car out just at the moment, so we've got all of these products still in here. Let's go and choose an address.

01:01

We'll keep an eye on our stocks table as well. So let's open this up and just keep that open. Let's click confirm order, and yeah, we need to add the fillable property to stock.

01:12

Let's head over to the model here, and let's jump down and of course, go ahead and add in that fillable column, and that's going to be amount.

01:22

Let's head back over, try that again, and make sure we choose an address. There we go. If we head over to our stocks table now,

01:32

we have a minus two and a minus five in there because of course, we chose two and five as our quantities. So the last thing we want to do is just clear out all of the items from the car.

01:44

So let's go ahead and say, we're going to call this remove all, or you could just call it clear. Let's go over to our car model,

01:52

and let's implement that remove all method, and all we're going to do here is access the car instance, go ahead and grab the variations relationship, and when we call detach on this relationship

02:08

without passing anything through, it's just going to remove all of these for us. So eventually now we're going to get to the point where these are removed from our car,

02:18

and of course, we're not going to see it up in the navigation. So if we go over to the database, let's clear out these negative stocks once again.

02:26

Let's clear this order out, or all of these orders, we can actually truncate this table, and let's try this from scratch. So let's choose an address,

02:37

let's go ahead and confirm this order and pay, and when we give this a refresh, we're actually redirected back to the car page because of middleware that we added earlier.

02:47

But of course, if we head over to the database, that order's been created, the variations have been attached, and then stocks have been reduced.
