Here is a list with all the ORM methods you might ever need. This is also a good documentation source: https://doc.openerp.com/trunk/server/api_models/

unlink method delete the record based on the given ID. Based on your requirement need to override copy Method.

unlink Method Example:-

Example 1: In button click call unlink method it will Delete records with given ids

                 self.unlink(cr, uid, ids, context=context)

Example 2: Sale Order:-  Allows to delete sales order lines in draft,cancel state only.

  def unlink(self, cr, uid, ids, context=None):
        if context is None:
            context = {}
        """Allows to delete sales order lines in draft,cancel states"""
        for rec in self.browse(cr, uid, ids, context=context):
            if rec.state not in ['draft', 'cancel']:
                raise osv.except_osv(_('Invalid Action!'), _('Cannot delete a sales order line which is in state \'%s\'.') %(rec.state,))
        return super(sale_order_line, self).unlink(cr, uid, ids, context=context)

Unlink method deals with the deletion of data based on condition.

@api.multi
def unlink(self):
    for order in self:
        if order.purchase_order:
            raise UserError(_('You cannot Delete this record'))
    return super(PurchasePerformance, self).unlink()
Here is a simple example of how to use unlink method if you do not want your record to be deleted.
For updation you will have to use write method

This works with Odoo 10.
    # DELETE POST
    # /[project]/admin/post/{menuId.id}/{post.id}/delete
    http.route(['/signage/admin/post/<model("signage.signage"):signage>/<model("signage.area.page"):page>/delete'],type='http', auth='user', website=True)
    def delete_postId (self, signage, page):
    #_logger.warn('<<<<<<<<<<<<<<<<<  signage = %s' % signage)
    #_logger.warn('<<<<<<<<<<<<<<<<<  postId = %s' % page)
    page.unlink()
    return werkzeug.utils.redirect('/signage/admin/menu/%s/edit' % signage.id)

In your class define the unlink method, this is called before deleting,
to see what happens I recommend doing this within your class

def unlink(self):
    print('-----------------------LLamada a unlink address')
    print(self)
    return super(youclassname, self).unlink()
