问题 I'm trying to add data to my database by rest API and I have some problems with adding the data. So basically I have added this data from the admin page, but I want to add this from my other python by using requests. When I'm sending post request it shows me that it has been added, but sensor array is empty [ { "id": 1, "name": "Stacja 1", "delay_time": 123, "sensor": [ { "id": 1, "name": "DS18B20", "type": "temperature", "date_created": "2020-06-26T16:30:28.657804Z", "value": 123.0, "index":

问题 I'm using Django Rest Framework 3.5.4 and Pycharm Professional 2016.3.1. Incidentally, I have PyCharm configured to use a virtualenv inside a local vagrant box. When I step through the DRF code with the debugger on, I can see that it is stepping through blank lines, and the variables in the debugger don't match those in scope (pictured here is rest_framework.response.Response.rendered_content() ): Here's another example that shows how variables in scope in the debugger don't match the single
