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.

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!”.
