Odoo11-显示带有cron任务的弹出消息

Question

I created a cron to compare the quantity of product in stock and the minimum quantity in the rules. I would like that every time the quantity in stock is lower than the minimum of the rules it shows me a popup.

When I run the cron automatically it does not display a message or error

Here is my code:

@api.model
def to_do(self):
    res_warehouse = self.env['stock.warehouse.orderpoint'].search([])
    for product in res_warehouse:
        quants = self.env['stock.quant'].search([
            ['product_id', '=', product.product_id.id],
            ['location_id', '=', product.location_id.id],
        ]).mapped('quantity')
        if quants:
            view = self.env.ref('stock_limit_alert.cron_wizard')
            view_id = view and view.id or False
            context = dict(self._context or {})
            context['message'] = 'OK'
            context['params'] = {'nom': product.location_id.id}
            if quants[0] <= product.product_min_qty:
                return {
                    'name':'Success',
                    'type': 'ir.actions.act_window',
                    'view_type': 'form',
                    'view_mode': 'form',
                    'res_model': 'cron.wizard',
                    'views': [(view.id,'form')],
                    'view_id': view.id,
                    'target': 'new',
                    'context': context
                }

不可能这样，因为cron在运行时在odoo的后端运行cron并不会影响odoo的运行环境，它在另一个环境中运行时，您可以在日志中看到它们，但不会影响您的运行环境。
