I have created relational columns with different class but when i delete relational records it will delete records from the base class as well.

Anyone have any solution to stop deleting the records from the base class while deleting relational field.

I have checked with ondelete='set null' on field declaration.

e.g i have create a field many2one with 'purchase.order', when i delete this record it delete the 'purchase.order' as well.

I want to stop deleting the purchase order while delete the record.

in order to stop the field one2many from deleting record witch is the default behavior of that field is when you creating you view give it an option:

<field name="one2many_field_name" options="{'not_delete': True}" />

In Odoo 8, use widget="many2many":

<field name="one2many_field_name" widget="many2many" />
