I use options="{'datepicker':{'minDate': 'now'}}" on a date field in a module I created to disable lower dates when saving. But there is an error that occurs when I select today's date. 

So I follow to modify the source code of the function which is in a library in the web module of Odoo (web/static/lib/tempusdominus/tempusdominus.js).

I would like to know how to inherit if possible from file to make my modifications without affecting the source code of odoo.

If you also have another method to solve the minDate problem, I'm interested.

Thanks
