I am working on changing the color in tree view in odoo 13 for colorize tree view when there is a difference of 15 days between two dates for example I have this when one is bigger than the other
tree decoration-danger=" (date1 > date2)"
but i need when there is a difference of 15 days between two dates.
Thanks
You should persist a boolean field diff_15
: True if difference(date1, date2) > 15 and False otherwise, then use this field in your XML to achieve the proper class decoration-danger="diff_15 == True"
I hope this can be helpful for you.
