Add expenses statuses We only want two statuses for expense: not yet paid (pending), and paid. Thus, it is a bit different from quotes and invoices, because expenses do not pass throw the “workflow” of created→sent→{pending,paid}. That’s way in this case the status field is already in the new expense form, instead of hidden, and by pending is not equivalent to created but unpaid (i.e., the same status color). With the new select field in the form, the file field no longer can span two columns or it would be alone on the next row. Closes #67.

Compute the total amount, base plus taxes, of all expenses This works mostly like invoices: i have to “update” the expense form to compute its total based on the subtotal and the selected taxes, although in this case i do no need to compute the subtotal because that is given by the user. Nevertheless, i added a new function to compute that total because it was already hairy enough for the dashboard, that also needs to compute the tota, not just the base, and i wanted to test that function. There is no need for a custom input type for that function as it only needs a couple of simple domains. I have created the output type, though, because otherwise i would need to have records or “reuse” any other “amount” output type, which would be confusing.\ Part of #68.

Split contact relation into tax_details, phone, web, and email We need to have contacts with just a name: we need to assign freelancer’s quote as expense linked the government, but of course we do not have a phone or email for that “contact”, much less a VATIN or other tax details. It is also interesting for other expenses-only contacts to not have to input all tax details, as we may not need to invoice then, thus are useless for us, but sometimes it might be interesting to have them, “just in case”. Of course, i did not want to make nullable any of the tax details required to generate an invoice, otherwise we could allow illegal invoices. Therefore, that data had to go in a different relation, and invoice’s foreign key update to point to that relation, not just customer, or we would again be able to create invalid invoices. We replaced the contact’s trade name with just name, because we do not need _three_ names for a contact, but we _do_ need two: the one we use to refer to them and the business name for tax purposes. The new contact_phone, contact_web, and contact_email relations could be simply a nullable field, but i did not see the point, since there are not that many instances where i need any of this data. Now company.taxDetailsForm is no longer “the same as contactForm with some extra fields”, because i have to add a check whether the user needs to invoice the contact, to check that the required values are there. I have an additional problem with the contact form when not using JavaScript: i must set the required field to all tax details fields to avoid the “(optional)” suffix, and because they _are_ required when that checkbox is enabled, but i can not set them optional when the check is unchecked. My solution for now is to ignore the form validation, and later i will add some JavaScript that adds the validation again, so it will work in all cases.

Return HTTP 404 instead of 500 for invalid UUID values in URL Since most of PL/pgSQL functions accept a `uuid` domain, we get an error if the value is not valid, forcing us to return an HTTP 500, as we can not detect that the error was due to that. Instead, i now validate that the slug is indeed a valid UUID before attempting to send it to the database, returning the correct HTTP error code and avoiding useless calls to the database. I based the validation function of Parse() from Google’s uuid package[0] because this function is an order or magnitude faster in benchmarks: goos: linux goarch: amd64 pkg: dev.tandem.ws/tandem/numerus/pkg cpu: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz BenchmarkValidUuid-4 36946050 29.37 ns/op BenchmarkValidUuid_Re-4 3633169 306.70 ns/op The regular expression used for the benchmark was: var re = regexp.MustCompile("^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}$") And the input parameter for both functions was the following valid UUID, because most of the time the passed UUID will be valid: "f47ac10b-58cc-0372-8567-0e02b2c3d479" I did not use the uuid package, even though it is in Debian’s repository, because i only need to check whether the value is valid, not convert it to a byte array. As far as i know, that package can not do that. [0]: https://github.com/google/uuid

Compute the total amount, base plus taxes, of all expenses This works mostly like invoices: i have to “update” the expense form to compute its total based on the subtotal and the selected taxes, although in this case i do no need to compute the subtotal because that is given by the user. Nevertheless, i added a new function to compute that total because it was already hairy enough for the dashboard, that also needs to compute the tota, not just the base, and i wanted to test that function. There is no need for a custom input type for that function as it only needs a couple of simple domains. I have created the output type, though, because otherwise i would need to have records or “reuse” any other “amount” output type, which would be confusing.\ Part of #68.

Add reset button to filters I want this button, as well as the submit button, to be on a row below the filters’ input, especially for quotes and invoices, that have the most filters and looks weird with the button wedged in. Thus, i added a <fieldset> around all the filters. Closes #69

Add total amount for quotes, invoices, and expenses tables We have shown the application to a potential user, and they told us that it would be very useful to have a total in the table’s footer, so that they can verify the amount with the bank’s extracts.

maybeAppendWhere("contact_id = $%d", form.Contact.String(), func(v string) interface{} {
customerId, _ := strconv.Atoi(form.Contact.Selected[0])
return customerId
})
Add expenses statuses We only want two statuses for expense: not yet paid (pending), and paid. Thus, it is a bit different from quotes and invoices, because expenses do not pass throw the “workflow” of created→sent→{pending,paid}. That’s way in this case the status field is already in the new expense form, instead of hidden, and by pending is not equivalent to created but unpaid (i.e., the same status color). With the new select field in the form, the file field no longer can span two columns or it would be alone on the next row. Closes #67.

Return HTTP 404 instead of 500 for invalid UUID values in URL Since most of PL/pgSQL functions accept a `uuid` domain, we get an error if the value is not valid, forcing us to return an HTTP 500, as we can not detect that the error was due to that. Instead, i now validate that the slug is indeed a valid UUID before attempting to send it to the database, returning the correct HTTP error code and avoiding useless calls to the database. I based the validation function of Parse() from Google’s uuid package[0] because this function is an order or magnitude faster in benchmarks: goos: linux goarch: amd64 pkg: dev.tandem.ws/tandem/numerus/pkg cpu: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz BenchmarkValidUuid-4 36946050 29.37 ns/op BenchmarkValidUuid_Re-4 3633169 306.70 ns/op The regular expression used for the benchmark was: var re = regexp.MustCompile("^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}$") And the input parameter for both functions was the following valid UUID, because most of the time the passed UUID will be valid: "f47ac10b-58cc-0372-8567-0e02b2c3d479" I did not use the uuid package, even though it is in Debian’s repository, because i only need to check whether the value is valid, not convert it to a byte array.

Compute the total amount, base plus taxes, of all expenses This works mostly like invoices: i have to “update” the expense form to compute its total based on the subtotal and the selected taxes, although in this case i do no need to compute the subtotal because that is given by the user. Nevertheless, i added a new function to compute that total because it was already hairy enough for the dashboard, that also needs to compute the tota, not just the base, and i wanted to test that function. There is no need for a custom input type for that function as it only needs a couple of simple domains. I have created the output type, though, because otherwise i would need to have records or “reuse” any other “amount” output type, which would be confusing.\ Part of #68.

Add option to export the list of quotes, invoices, and expenses to ODS This was requested by a potential user, as they want to be able to do whatever they want to do to these lists with a spreadsheet. In fact, they requested to be able to export to CSV, but, as always, using CSV is a minefield because of Microsoft: since their Excel product is fucking unable to write and read CSV from different locales, even if using the same exact Excel product, i can not also create a CSV file that is guaranteed to work on all locales. If i used the non-standard sep=; thing to tell Excel that it is a fucking stupid application, then proper applications would show that line as a row, which is the correct albeit undesirable behaviour. The solution is to use a spreadsheet file format that does not have this issue. As far as I know, by default Excel is able to read XLSX and ODS files, but i refuse to use the artificially complex, not the actually used in Excel, and lobbied standard that Microsoft somehow convinced ISO to publish, as i am using a different format because of the mess they made, and i do not want to bend over in front of them, so ODS it is. ODS is neither an elegant or good format by any means, but at least i can write them using simple strings, because there is no ODS library in Debian and i am not going to write yet another DEB package for an overengineered package to write a simple table—all i want is to say “here are these n columns, and these m columns; have a good day!”.
