## Transcript

foreign hey what's up welcome back in this episode you're going to learn about check out stripe checkout and fulfillment what we're going to start doing is keeping track of which of those customers have bought which products and we're going to do that in the database when we receive a web hook notification telling us that stripe checkout has succeeded so the first thing we want to do is start modeling what this is going to look like so in the database we're going to have a New Concept called a customer so we're going to say rails generate model customer that's going to have a stripe ID it also is going to have an email address and each customer is going to be related directly to a store that they bought from we could make this directly related to the user but I think in the future if we wanted to have multiple stores we would want to segment out certain customers that buttons at some stores with customers that bought at other stores this customer model might also someday become something that is device authenticatable where a customer can log back in and see their purchases but for now each time someone goes through checkout we're just creating a brand new customer for them and we're not handling any sort of authentication of an existing customer so we're going to generate this model for a customer now let's think a little bit about these fields and what we might want to do with them I think we want to ensure that every single customer definitely has an email address but I could see a case for some reason if you have a friend that you wanted to you know give your ebook to you could just give them access by creating a customer without a stripe ID and then saying that this customer is somehow associated with some sort of product so we're going to create this table we also want to ensure that there is some sort of uniqueness between a customer their stripe ID and the store ID I believe so that we don't have the same email address in there multiple times for the same store so let's say that we are going to add an index on the customers table for the relationship between the store ID and the email address we want to make sure that that is unique all right we'll migrate the database and jump into the customer model and inside of the customer model we're going to say validates that the store ID is unique in the scope of the email address right that's this the same thing that we just created at the database layer now we want to add that validation at the model layer now that we have a customer let's keep track of what they purchased so we're going to say rails G model customer product I think this is how we want to track it we could also call this the order model or the purchase model or something this is going to be the reference to the customer and the reference to the product and we're also going to keep track of the checkout session ID that's going to be the stripe checkout session ID we might even want to keep a few other just denormalized things here but for now I think that's going to be a great a great start so we're going to have a customer product yeah all right so let's open this up and one of the another index that we want to add is going to be for the combination of all three of these so we want to ensure that there is a unique customer ID and product ID and checkout session ID the reason is that I could see someone coming back and repurchasing the same product multiple times but each time they purchase it should have a unique session ID so let's add that validation there okay I think that's a good start so we'll say reels DB migrate and then we'll jump into that customer product okay let's see uh the index name is too long since the name is too long we got to go give this thing a specific name so we're going to open this up and say that the name for this index is just like customer product session index rails DB migrate and we are good so let's open the customer product and this customer now belongs I'm sorry the customer product belongs to a customer and so the customer now has many customer products and it also has many products through customer products similarly on the product side we want to say that a product has many customer products and has many customers through customer products that gives us this many-to-many relationship between customers and the products that they might purchase all right let's jump into the web hook Handler here and let's handle the uh checkout session dot completed event and we're going to say handle checkout session completed handle checkout session completed and here this session is going to be event.data.object but by default when we receive the web hook notification about the checkout session it's not going to have the line items so what we want to do is re-retrieve that checkout session so we're going to say stripe checkout session.retrieve and we're going to pass in the ID of the checkout session and we're also going to pass in expand for the line items of the checkout session that is going to be our first argument and the second argument is we need to have the stripe account that the checkout session is related to so we're going to pass that down next finally we're going to be able to like create all of these intermediate objects so the first thing we want to do is create a customer if it does not already exist so let's say customer dot find or initialize by their stripe ID which is going to be this checkout session customer and their store ID which where are we going to find the store ID so the store ID should be available on the product which we're going to find by yeah so product dot find by the stripe ID which should be session.line items dot data zero dot price dot product so that should give us the product back the store ID should be product dot store ID I think let's check out the product model and just make sure that we have that okay so it does not the product is not directly related to a store so a product has one stored through the user model so this is going to be maybe we'll just pass in reference to the store directly okay so find or initialize the customer by that then we want to set their email up to be the session customer details.email and then we're going to save the customer now after the customer was saved then we want to create a customer product so we're going to say customerproduct dot create uh bang and this is going to be the customer the product and the checkout session ID which is going to be the sessions ID this will track sort of like every single product at that specific customer Buys so we're kind of just like looking up the customer or upsetting the customer basically and then after we have upserted the customer we're going to create this product reference so let's go over here also notice this is kind of fun right as we're testing a bunch of money is flowing into our payments balance recall that we're building out this Creator platform and this is what a store might look like let's say test.lvh dot me okay so let's go buy a product we're going to buy build and learn so we click on that link we're brought to this page test at example.com okay now the web hook Handler should be processing that checkout.session.completed event and redirecting us back so let's take a look in the logs in the server logs and see how everything is going it looks like those events are flowing through just fine process look at that thank you it's on the way we were redirected back to this checkout page now if we open up rails console we can see customer.count we have one customer it's a customer.last and they have their stripe customer ID in there they've got their email address we also have a store ID in here so we know which customer or which store this customer purchased from so that is all really cool now let's look at this customer's products so now we see the products that that customer has purchased so here's one of those products so that is pretty neat uh okay so at this point we should be automating at least automating the association between a given customer and their product now I think what we might want to do now is sort of like email the customer a link to where they can download the product so we're we're back to this page we have successfully received payment in fact we can double check that too and say like if session.status does not equal uh paid then return if the payment status payment status if the payment status is not paid then return so check out session payment status should be Let's see we can re-retrieve this because on our customer.last Dot customer products we have the checkout session ID you can say stripe checkout session dot retrieve pass we also need to pass in the stripe header which is going to be stripe count and that is going to be like store to find one or count.first.stripe ID and when we retrieve this there is going to be a payment status and that payment status is paid if we're using any of the like sort of delayed notification payment methods like it for instance if we wanted to enable an ACH payment maybe our digital download is a course it's two thousand dollars to download the course and the course comes with PDFs and maybe videos and some other things then we might offer folks to be able to pay with ACH ACH is delayed notification that means we won't immediately know whether or not that worked and so if we want to support delayed notification payments then we also need to handle checkout session async payment succeeded and we're going to handle that event in the same exact way so handle checkout session completed now that we're checking to see that the payment status is paid as long as it's paid will continue forward um like finding the looking up the product and or the customer and creating this Association here okay so now what we can do is we can go back through let's go back through the flow just one more time to test it out and we're going to buy the same product it's fine that we're going through let's do another email example.com all right we're redirected back now we should see a new customer dot last we see a new customer was added to the database now we have two customers customer product dot last yep so we can see another another relationship there between the customer and the product so this is this whole flow is now working we're able to create customers in the database when they purchase products the next thing I wanted to do was let's make a way that we can see who the customers are so whereas a rails G controller customers it's going to have an index it's going to have a show probably and that will give us probably more than enough go to routes add resources customers in the customer's controller we'll say customers is current user.store customers show at customer is current user.store.customers.find okay that should be just fine now let's go to the customers index and here we're going to have some table but first we'll grab our little header okay and then we'll go to Tailwind UI we'll grab a table so we're going to copy this table here which looks very much like a customer table all right every time I click sometimes when I click that it doesn't seem to work okay so now this is going to be called customers all the customers who have bought from your store all right and then we'll iterate over each of the customers and for each customer we want to print out at least their email address so let's do that here all right we can also do their their stripe customer ID customer.stripe ID that's probably good and we could make that a link too their stripe account um actually since we're using custom connect we wouldn't have a way to link to the dashboard or anything so this is going to be just fine so now we should have a slash customer's view uh undefined method customers for store so let's go to the store and a store should has many customers oh actually so a store has oh this is good yeah okay so it's going to be has many customers through products because products also has one store okay no Custer yeah products has customers so we should be able to get two customers through the store all right so here's the list of our customers that's pretty neat we don't need this add user button we also don't need some of this stuff at the very top so we're just going to go to the customers index and clean things up just a little bit so foreign or remove these all right we can actually remove this whole header let's actually make this a link to view the customer so we'll say this is going to be the customer path for customer and instead of edit we're going to say View and we'll make that bring us to the customer's show page so that on the customer show page we'll just say this is the customer um what do we want to show on the show page well here we can put out their customer.email as the header and then I think it might be nice to show a table with all of the products that they purchased so let's copy this drop it in and then here what we can do is we can now iterate over their products list of all the products this customer has purchased uh all right and here we're going to iterate over at customer.products that each do product and we'll just put out the name of the product .name see how that looks foreign no such customer email so this should be at customer okay test at example.com a list of the products that this customer purchased this is the ebook that they purchased and we can now remove title email role this is actually just email or this is the name of the product and now we can remove member and the link at the end so right now it's really just a table with one thing in it but eventually we could add more to this uh all right let's go also add a menu item so we're gonna go to application Helper and add this as a menu item customers let's clean this up while we're here this should all just be paths products path counts path okay so now of course I broke something all right now we have customers so now we have this link and we can see the list of customers now if someone else goes to our store and they decide to pay and maybe they're going to buy the productive rails book and they come over here and they enter in their password as new customer at example.com maybe they are going to buy with a card that is going to also skip the balance that would be nice skip balance all right okay let's click on pay now we should get a new customer object we should also have a new purchase or a customer product in the data in the database and we should also see this money this 100 should hit our available balance immediately and be available on the dashboard so let's go over to our dashboard here refresh now we see this new customer showed up that's pretty cool we may want to reorder this so the newest customers appear at the top but now in our dashboard we also see this 100 minus fees is immediately available and we can click on payout that will move it down to our financial account balance immediately or just after a second here so we see 31.75 is now 128 so that's pretty sweet okay so now we have the ability to track down specific customers and their purchases so I think that is a pretty good stopping point for fulfillment thanks so much for watching and we will see in the next one [Music]
