change variables defined in __init.py in django from other file

my init.py in django project

from pymodm.connection import connect, _get_db

from pymongo import MongoClient


client = MongoClient()
entity_record_clctn = client['platform_configuration'].entity_record_model
entity_clctn = client['platform_configuration'].entity_model

my tests.py in django project

from data_upload import client, entity_clctn, entity_record_clctn
class EntityRecordsTests(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        print("setup")
        global client
        global entity_clctn
        global entity_record_clctn
        entity_record_clctn = client['test_database'].entity_record_model
        entity_clctn = client['test_database'].entity_model

i am not able to change variables defined in init.py when these varibles are used in other files like views.py where i use them they point to the earlier values only can i do it? how?

this is my view.py

from data_upload import entity_clctn, entity_record_clctn
def get_entity_keys_by_name(name):
    entity = entity_clctn.find_one({"name": name})
    return [entity['entity_primary_key'], entity['entity_display_name']]
