Hi,

Can you add this to return and see: 

'context': {'create': False, 'delete': False}

Like:

@api.multi
def action_view_product(self):
    return {
        'type': 'ir.actions.act_window',
        'name': 'Products',
        'view_mode': 'form',
        'view_type': 'form',
        'res_model': "product.template",
        'res_id': self.id,
        'target': 'new',
        'context': {'create': False, 'delete': False},
    }

Thanks
