Unable fetch Products in TransientModel odoo 11

Question

So far i had read many questions but i am sure that i am total a mix up because i am unable understand how to use Search at odoo TransientModel. I had written a code that get Active_ids from self

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

I am supposing these actives_ids as product_tmpl_id but when i tried to use them

  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 ]

but its always return

result[rec.default_code ]
KeyError: '1'

Here is my full code

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 ]

Here is the Error

Everything seems to be fine with the Transient Model, the problem is that you're trying to read a dictionary value whose key doesn't exist yet. I mean, the default_code of the first product you get in the loop is 1, and you're telling Python: I want to read the value of the key 1 of the dictionary result, but this one is empty, so you get the error (you need to fill it in first).

You can reply the error in a Python console, this is what is happening to you:

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

You should do something like this to make it work:

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