I am a starter in odoo.in CRM Module ,manager should be notified 90 days prior to expiry of field (subscription) and automatically
Can anyone help me to achieve this goal. Thanks in advance.
Required basic knowledge of JS.
If you want to send automatic mail on expiration then here is a trick:
Go to your enterprise addons folder then search for a web_enterprise module.
Their is static folder , in that folder you'll find home_menu.js.
In this js you'll find method like _enterpriseExpirationCheck.
Go to that method and their is a variable called diffDays (calculated days of your expiration validity).
Put your condition like : if (diffDays === 30)
then make rpc
call to send mail with python.
That's it.
You'll find RPC call example in:
