python - 无法在 TransientModel odoo 11 中获取产品

Question

到目前为止，我已经阅读了很多问题，但我确信我完全搞混了，因为我无法理解如何在 odoo TransientModel 中使用搜索。 我写了一段代码，从 self

获取 Active_ids

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

我假设这些 actives_ids 作为 product_tmpl_id 但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 ]

这里是错误

transient 模型似乎一切都很好，问题是您正在尝试读取其键尚不存在的字典值。我的意思是，您在循环中获得的第一个产品的 default_code 是 1，您是在告诉 Python:我想读取键 的值字典 result 的 1，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，这就是您遇到的情况:

>>> 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让它工作:

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