Add the company relation and read-only form to edit I do not have more time to update the update to the company today, but i believe this is already a good amount of work for a commit. The company is going to be used for row level security, as users will only have access to the data from companies they are granted access, by virtue of being in the company_user relation. I did not know how add a row level security policy to the company_user because i needed the to select on the same relation and this is not allowed, because it would create an infinite loop. Had to add the vat, pg_libphonenumber, and uri extensions in order to validate VAT identification numbers, phone numbers, and URIs, repectively. These libraries are not in Debian, but i created packages for them all in https://dev.tandem.ws/tandem.

Handle tax details and new tax forms with structs and validation I implemented the Valuer and Scanner interfaces to InputField and SelectField for better passing values between the database and Go. I had a conflict with the Value name and renamed the struct member to Val. I also had to change the attributes array to be of type template.HTMLAttr or html/template would replace `form="newtax"` attribute to `zgotmplz="newtax"` because it deems it “unsafe”. I do not like having to use template.HTMLAttr when assigning values, but i do not know what else i can do now.

Allow to change the current year’s invoice number counter This is for new users that do not start using the application from the beginning of the current fiscal year and, therefore, need to create invoices starting from a specific number. I had to change the constraint on the currval to allow zero, otherwise it would not be possible to set 1 as the next number, because users can also not delete the row.

Convert from cents to “price” and back I do not want to use floats in the Go lang application, because it is not supposed to do anything with these values other than to print and retrieve them from the user; all computations will be performed by PostgreSQL in cents. That means i have to “convert” from the price format that users expect to see (e.g., 1.234,56) to cents (e.g., 123456) and back when passing data between Go and PostgreSQL, and that conversion depends on the currency’s decimal places. At first i did everything in Go, but saw that i would need to do it in a loop when retrieving the list of products, and immediately knew it was a mistake—i needed a PL/pgSQL function for that. I still need to convert from string to float, however, when printing the value to the user. Because the string representation is in C, but i need to format it according to the locale with golang/x/text. That package has the information of how to correctly format numbers, but it is in an internal package that i can not use, and numbers.Digit only accepts numeric types, not a string.

Add fieldset for currency in tax details page

type CurrencyOption struct {

Use a select for company’s country field At first we thought that a regular text field would do, because we were afraid that a dropdown would be worse from the point of view of user experience, but then we realized that we need the country code for VAT and phone validation, and we can not expect users to input that, of course. I had to add the first “i18n table” to the database with the name of all countries in both Catalan and Spanish and Catalan; English is the default. For now i think i do not need a view that would select the name based on the locale of the current request, because currently i do not plan on adding any other such table —the currency uses the code and the symbol, thus no need for localization. However, now i need the language tag from the locale in order to get the correct translation, and gotext does not give me any way to access the inner language. Thus the need for our Locale type.

type Tax struct {
Introduce the concept of tax class We want to show the percentage of the tax as columns in the invoice, but until now it was not possible to have a single VAT column when products have different VAT (e.g., 4 % and 10 %), because, as far as the application is concerned, these where ”different taxes”. We also think it would be hard later on to compute the tax due to the government. So, tax classes is just a taxonomy to be able to have different names and rates for the same type of tax, mostly VAT and retention in our case.

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.

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.

The company is going to be used for row level security, as users will only have access to the data from companies they are granted access, by virtue of being in the company_user relation. I did not know how add a row level security policy to the company_user because i needed the to select on the same relation and this is not allowed, because it would create an infinite loop. Had to add the vat, pg_libphonenumber, and uri extensions in order to validate VAT identification numbers, phone numbers, and URIs, repectively.

I had to add the first “i18n table” to the database with the name of all countries in both Catalan and Spanish and Catalan; English is the default. For now i think i do not need a view that would select the name based on the locale of the current request, because currently i do not plan on adding any other such table —the currency uses the code and the symbol, thus no need for localization. However, now i need the language tag from the locale in order to get the correct translation, and gotext does not give me any way to access the inner language. Thus the need for our Locale type.

Introduce the concept of tax class We want to show the percentage of the tax as columns in the invoice, but until now it was not possible to have a single VAT column when products have different VAT (e.g., 4 % and 10 %), because, as far as the application is concerned, these where ”different taxes”. We also think it would be hard later on to compute the tax due to the government. So, tax classes is just a taxonomy to be able to have different names and rates for the same type of tax, mostly VAT and retention in our case.

Handle tax details and new tax forms with structs and validation I implemented the Valuer and Scanner interfaces to InputField and SelectField for better passing values between the database and Go. I had a conflict with the Value name and renamed the struct member to Val.
