You can loop through the folders using a foreach loop call the create function:

As you try doing is not possible. It's important to understand the odoo logical.

All informations showing in Odoo coming from a DB.

When you try called a field with a compute method (I think you try a compute method because you set an @api.depends). If you don't have a record the compute will not be called.

If you want connected a external data to your Odoo, you have 2 possibilities.

The easier method is create the external data in your database.

To do this you can create a CRON, this CRON will call your extrenal data and set in DB.

1. Create a CRON. Called every X Minutes / Hours / Days
2. In the CRON method, call your external data.
3. Format data to match with Odoo DB
4. Search already existing data in you db with self.env['your_model'].search([...])
5. Create or Update data with method create or write

In Odoo you have a commun method called read. This method is called each time when the Odoo try read data from cloud. You can overriden this method of your model to return "ephemeral" data.

This option is for my opinion the better solution BUT this method is very complicated to make it realy 100% sure. And I don't will explain all the solution here.

Juste for your information.

1. You need override read method (def read(self, fields,load)).
2. Remove the basic logical of Odoo to fetch data in DB and replace it by your data.
3. Overriden method search, create, write, unlink.
