actually my requirement is record will be save only if i click save button. but whenever i click button in my form then duplicate record saved in my table. so how to sort out this issue in odoo 8 ?
Every button that has an action like add discounts, open another form, update function fields.... and more... Every button is going to save the data, because some of them need the active_id (actual id of the form), so they need it to be stored, function fields needs records to be stored to work. The only operation that you can do without saving the form is ON CHANGE, because you are passing arguments and it's returning something.... But the rest operations, are going to be stored.
