Hello everyone,

I created a Save Button in the Quotation Form. After the quotation form is created or edited the save button must be hidden or invisible. 

Most Odoo modules use the "state" field for this problem in order to make the button invisible but I want the save button hidden after a form is saved or edited. Thank you. Below is my code:

Python Code (Server Action)

def save(self, cr, uid, ids, context):
    return True
