To add an additional menu in action dropdown list on tree view, we need to register “ir.actions.server” and “ir.values” on the qweb/xml file as follow. Note that code field name is using old Odoo python API. In your sale order model create the method as bellow with Odoo new API. Restart odoo and upgrade your module, you’ll have now cancel menu on your sales order tree view.

I will describe the basis in python to import xlsx file and how to handle the imported data, in this exemple sales orders is imported. Uploaded file is stored in the variable upload_file and is encoded in base 64, to read it we have to decode first the data by using b64decode function, then save it, for me i chose “/tmp” folder. Result import_data is an array of dictionary as follow [{‘column_name_1’:data_column_1_row_1, ‘column_name_2’:data_column_2_row_1,…},{‘column_name_1’:data_column_1_row_2, ‘column_name_2’:data_column_2_row_2,…},…] Bellow XML view for the importation module.
