Disable previous dates in Odoo datepicker - datepicker

Question

I want to restrict the user selecting previous date from the date picker of odoo-8. Please give me how to disable previous dates in odoo datepicker

Answer 1

There's a module for that https://apps.openerp.com/apps/modules/8.0/web_widget_datepicker_options/
If you have a date field named current_date
<field name="current_date" />
After installing the module, just add the option for the jquery datepicker minDate and set it to 0 like this
<field name="current_date" options="{'datepicker':{'minDate': 0}}"/>
Screenshot
I previously did this by
setting an onchange on the field that'll be triggered every time the field is changed, and in the onchange you can convert the date to a python date (with odoo's default time format) and compare it to the current date
from datetime import datetime
from openerp import api
from openerp.tools import DEFAULT_SERVER_DATE_FORMAT
from openerp.exceptions import Warning
#api.onchange('current_date')
def onchange_date(self):
if datetime.strptime(self.current_date, DEFAULT_SERVER_DATE_FORMAT).date() < datetime.now().date():
raise warning('Please select a date equal/or greater than the current date')
return False
return my_date
