convert array of strings inside of string into a python list
I've sent some form-data from my React client to my Django + DRF api.
inside of the form-data I have an attribute date_strings which is an array of date-time strings. i.e. ["date1", "date2", "date3"]
in order to send it to my Django api I converted the array of strings into a string using JSON.stringify
const myForm = new FormData();
myForm.set("date_strings", JSON.stringify(dateStrings));
in the create method of my serializer, I'd like to convert this data into a list.
def create(self, validated_data):
stringified_array = validated_data.pop('date_strings')
// stringified_array: '["date1", "date2", "date3"]'
how can I convert an array of strings inside of a string into a python list?

I've tried using json.loads but it doesn't work. I think this is because this is an array and not formatted json

Works just fine for me. Are you certain that your data is in the format posted above?

I think the problem is probably with your input,[", "name": "server.posts.serializers", "levelname": "INFO", "request_id": "none"}doesn't seem right to me...

You can easily turn strings into lists using .split. However, you have to remove the outermost characters [" and "] because otherwise these will also be added to your list of strings.
stringified = '["date1", "date2", "date3"]'
unstringified = stringified[2:-2].split('", "')
returns
['date1', 'date2', 'date3']
A much better solution as mentioned by @mhodges
import json
stringified = '["date1", "date2", "date3"]'
unstringified = json.loads(stringified)
Which also outputs:
['date1', 'date2', 'date3']

This is the correct answer! I made a mistake, json.loads() works correctly. I tried using json.loads before, but I had a log below it so kept getting the message["TypeError: must be str, not typen"]
