Override main view with modules

im using self-hosted version of invoice ninja.
i create a cron to do automatic updates with an sh file and its working great , my app is up to date 4.5.5
i just want to extend the invoice and quote view with a custom module… i want to add a variable in the template pdf invoice and quote that automatic convert the total into letters …
i already build it but i did touch the core app :frowning:
i tried with the docs online in section of “Extend core view” but didn’t work …
any help? thanks.

I don’t think this will be possible using a custom module.

:frowning: to bad … any suggestion please how i can achieve it …another way … and i always i want to keep my app up to date

Not that I’m aware of

thanks … i will drop the automatic update then
