Question

到目前为止，我已经阅读了很多问题，但我确信我完全混淆了因为我无法理解如何在odoo TransientModel上使用搜索。我编写了一个从自我获取 Active_ids 的代码

context=self.env.context.get('active_ids')

我假设这些actives_ids为 product_tmpl_id但是当我尝试使用它们时

  product_recs = produtc_obj.search([('product_tmpl_id', 'in', context)])
    print(product_recs)
    result = {}
    for rec in product_recs:
        print(rec.default_code )
        result[rec.default_code ]

但它总是返回

result[rec.default_code ]
KeyError: '1'

这是我的完整代码

import logging
from odoo import models, fields, api
from odoo.exceptions import Warning
_logger = logging.getLogger(__name__)

class product_export_to_rakuten(models.TransientModel):
    _name = 'rakuten_ftp.export_product'

    @api.multi
    def export_products(self):
        # check for more than one orders.
       # print(self.env)
        context=self.env.context.get('active_ids')
        produtc_obj = self.env['product.product']

        product_recs = produtc_obj.search([('product_tmpl_id', 'in', context)])
        print(product_recs)
        result = {}
        for rec in product_recs:
            print(rec.default_code )
            result[rec.default_code ]

这是错误

瞬态模型似乎一切都很好，问题是你正在尝试读取其密钥尚不存在的字典值。我的意思是，你在循环中得到的第一个产品的default_code是 1 ，你告诉Python：我想读取密钥 1的值result的em>，但是这个是空的，所以你得到错误（你需要先填写它）。

您可以在Python控制台中回复错误，这就是您发生的事情：

>>> result = {} >>> result['1'] Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: '1'

你应该做这样的事情来使其发挥作用：

>>> result = {} >>> result['1'] = 'Your value' # result.update({'1': 'Your value', }) >>> result['1'] 'Your value'

在TransientModel odoo 11中无法获取产品
