Add the relation to store the expense’s attachment files It is a separate table because we allow expenses to not have such an attachment, although we allow only an attachment per expense, and i do not want to have a bunch of nullable columns for that. I decided to keep the files in the database, contrary to “conventional wisdom” of storing files in the filesystem, because these attachments are invoices and such documets that are an integral part of the expense relation. In other words, losing these files would render the expense (almost) useless. Thus, the ACID guarantees of the database are the most appropriate place for them.

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.
