how to desrialize json to object in python or django

Question

I am new to python and django. i must consume a web service and the response of web service is json like this:

[{'name': 'gfile1.txt', 'length': 448, 'createdDate': '1582229671352'}, {'name': 'gfile2.txt', 'length': 86, 'createdDate': '1582229671474'}, {'name': 'soc-LiveJournal1.txt', 'length': 1080598042, 'createdDate': '1582229715227'}]

also i have a class according to this json result: the below is class definition:

class DataParameter: def __init__(self, name, size, _createdDate): self.filename = name self.filesize = size self.createdDate = _createdDate

what should i do is: i must convert the above json to list of DataParameter class. Can you help me to do this? Thanks

why not use DRF parser django-rest-framework.org/api-guide/parsers/… — devdob

If I understand you correctly, you can try something like this:

data = [ {'name': 'gfile1.txt', 'length': 448, 'createdDate': '1582229671352'}, {'name': 'gfile2.txt', 'length': 86, 'createdDate': '1582229671474'}, {'name': 'soc-LiveJournal1.txt', 'length': 1080598042, 'createdDate': '1582229715227'} ] class DataParameter: def __init__(self, name, size, _createdDate): self.filename = name self.filesize = size self.createdDate = _createdDate new_list = [] for i in data: new_list.append(DataParameter(i['name'], i['length'], i['createdDate'])) print(new_list)

Here's a quick and dirty alternative

class DataParameter: def __init__(self, name, size, _createdDate): self.filename = name self.filesize = size self.createdDate = _createdDate @classmethod def from_json(cls, json_str): lst = [] for dct in json: lst.append(cls(**json_dict)) return lst #Usage my_json = [{'name': 'gfile1.txt', 'length': 448, 'createdDate': '1582229671352'}, {'name': 'gfile2.txt', 'length': 86, 'createdDate': '1582229671474'}, {'name': 'soc-LiveJournal1.txt', 'length': 1080598042, 'createdDate': '1582229715227'}] DataParameter.from_json(my_json)
