Add payment relation and use it to compute the booking’s cart I had to add the payment concept separate from the booking, unlike other eCommerce solutions that subsume the two into a single “order”, like WooCommerce, because bookings should be done in a separate Camper instance that will sync to the public instance, but the payment is done by the public instance. There will be a queue or something between the public and the private instance to pass along the booking information once the payment is complete, but the public instance still needs to keep track of payments without creating bookings. To compute the total for that payment i had to do the same as was doing until now for the cart. To prevent duplications, or having functions with complex return types, i now create a “draft” payment while the user is filling in the form, and compute the cart there; from Go i only have to retrieve the data from the relation, that simplifies the work, actually. Since the payment is computed way before customers enter their details, i can not have that data in the same payment relation, unless i allow NULL values. Allowing NULL values means that i can create a payment without customer, thus i moved all customer details to a separate relation. It still allows payment without customer, but at least there are no NULL values. Draft payments should be removed after a time, but i believe this needs to be done in a cronjob or similar, not in the Go application. To update the same payment while filling the same booking form, i now have a hidden field with the payment slug. A competent developer would have used a cookie or something like that; i am not competent.

Change draft_payment return type to row of payment This way i can use the function in the from clause of the query that i already had to do to get the totals formatted with to_price. In this case, i believe it is better to leave out Go’s function because it would force me to perform two queries. Instead of binding a nullable string pointer with the payment’s slug, i wanted to use pgtype’s zeronull.Text type, but it can not work in this case because it encodes the value as a text, while the parameters is uuid. I can not use zero.UUID, because it is a [16]byte array, while i have it in a string. Thus, had to create my own ZeroNullUUID type that use a string as a base but encodes it as a UUID.

Add down payment Customer wants to require a down payment of 30 % for bookings made one week or more before the actual date, and to make the full payment otherwise. This would require yet another relation to keep these values. Fuck it; i added them to the function, as they are very unlikely to change. That forced me to change the test for draft_payment to use relative dates, otherwise there is no way i can have stable results in the future.

Add the admin page to see payments Had to do a couple of changes to the database: add the currency_code to the payment relation, to format the price according to the payment’s currency instead of the company’s; and the reference SQL function, to replace the equivalent golang function, so that i can use it to index payments. The rest is mostly the same as any other page, except that the individual payment’s page is not a form, but a regular info dump. I also moved the payment settings as a sub-route of payments, as i believe this makes more sense than an additional user menu item.

Add payment relation and use it to compute the booking’s cart I had to add the payment concept separate from the booking, unlike other eCommerce solutions that subsume the two into a single “order”, like WooCommerce, because bookings should be done in a separate Camper instance that will sync to the public instance, but the payment is done by the public instance. There will be a queue or something between the public and the private instance to pass along the booking information once the payment is complete, but the public instance still needs to keep track of payments without creating bookings. To compute the total for that payment i had to do the same as was doing until now for the cart. To prevent duplications, or having functions with complex return types, i now create a “draft” payment while the user is filling in the form, and compute the cart there; from Go i only have to retrieve the data from the relation, that simplifies the work, actually. Since the payment is computed way before customers enter their details, i can not have that data in the same payment relation, unless i allow NULL values. Allowing NULL values means that i can create a payment without customer, thus i moved all customer details to a separate relation. It still allows payment without customer, but at least there are no NULL values. Draft payments should be removed after a time, but i believe this needs to be done in a cronjob or similar, not in the Go application. To update the same payment while filling the same booking form, i now have a hidden field with the payment slug. A competent developer would have used a cookie or something like that; i am not competent.

Add the admin page to see payments Had to do a couple of changes to the database: add the currency_code to the payment relation, to format the price according to the payment’s currency instead of the company’s; and the reference SQL function, to replace the equivalent golang function, so that i can use it to index payments. The rest is mostly the same as any other page, except that the individual payment’s page is not a form, but a regular info dump. I also moved the payment settings as a sub-route of payments, as i believe this makes more sense than an additional user menu item.

Add the number of maximum nights that tourist tax applies This is required by law. I do not know why i have this value and the tax amount in the database, but the payment percent and the number of days are hardcoded. I guess i am such an inconsistent mess.

Create new drafts if trying to modify an already pending payment This can happen when the customer reaches the payment page, but then returns back to the booking form via the back button: the browser remembers the URI with the cart slug, trying to make it ready, and then it fails because it is already pending. I did not like the idea of modifying a payment that is already not a draft, because it seems to me that can lead to errors if we receive Redsys notifications of payments that are being changed back to draft. In fact, i believe that draft payments maybe should go to a different relation altogether, so that i can prevent UPDATE on payment by guests, but maybe i am going overboard now.
