saving day wise logs in Azure App Service for Django Application
Below is the logging format I have for a DRF application in azure app service. I tried using Timed Rotating File handler but I was not able to save the logs with that option. Also, when ever the app service restarts, the previous logs are getting erased. Is there a way to maintain day wise logs in azure app service.

How to get a Model variable name from another model in django
I have two models in django model Model.py class RequestTemplate(models.Model): name = models.CharField(max_length=50) Author=models.CharField(max_length=50) defaultvalues=models.CharField(max_length=50) class Request(models.Model): name = ?? # Author = ?? starttime = models.DateTimeField(default=timezone.now) endtime = models.DateTimeField(default=None) so the idea is that i want to create Requesttemplate which i can use in the future to create a Request object that will take the name and the Author variables from the template. I tried to use Forgienkey to the name variable, but in case i updated the template in the future i dont want to get my Request updated. Conclusion: I want to connect the Request with the template for one time (to get the variables names) and then keep it independent from the template. Any ideas? -

How to accelerate the landing web page using Django on Digitalocean?
I created a "landing page website" using Django, it's a very simple website for using just for showing up the data with no query sets that coming from the database it's just 3 or 4 queries. I'm using the Nginx server for deploying and everything working properly but just the loading of the page is very very slow, I don't know where can I find the issue. I thought that the problem might become from Nginx since it has the ability to manage static files and also, I thought about maybe droplet cause such that issue. my brain is frozen about finding the core of that problem where I can't think of where the problem may happen so, how can I accelerate my web page, and what are the reasons for that problem? I don't know if StackOverflow is a good choice to ask such that question or not but I will be grateful for solving that problem in advance -

Should Response be imported or mocked when using unittest.mock
I'm learning unittest and unittest.mock with the latter not quite clicking. I'm mocking the response of an end-point and had the following: import unittest from unittest.mock import patch from rest_framework.test import APIClient class CoreTestCase(unittest.TestCase): @patch('core.views.CoreViewSet.list') def test_response(self, mock_get): mock_get.return_value = [{'hello': 'world'}] client = APIClient() response = client.get('/core/') print(response.data) Which resulted in the following error: AssertionError: Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'list'>` Made sense because DRF uses Response. To get around the error I modified to: import unittest from unittest.mock import patch from rest_framework.test import APIClient from rest_framework.response import Response class CoreTestCase(unittest.TestCase): @patch('core.views.CoreViewSet.list') def test_response(self, mock_get): mock_get.return_value = Response([{'hello': 'world'}]) client = APIClient() response = client.get('/core/') print(response.data) Which achieved the desired result and I was just passing in an array of objects (or list of dicts). However, I'm not sure this was the correct way of handling this and if Mock() should have been used instead. I can honestly say I haven't been able to figure out how to use Mock() or MagicMock() correctly, or find a tutorial that explains it clearly, so my attempts at using it with: mock_get.return_value = Mock([{'hello': 'world'}]) Just resulted in: TypeError: 'module' object … -

Django conditional inserts in multiple fields
I have two Django model: Object and Purchases. On the Object model, there are two fields: date_most_recent_purchase and date_first_purchase. I am inserting many dictionnaries, and each dictionnary can have the following values (of course, the date and object_id can be any value): {"object_id": 1, "date_purchase": None, "date_first_purchase": None} {"object_id": 1, "date_purchase": None, "date_first_purchase": "2020-11-11"} {"object_id": 1, "date_purchase": "2019-12-12", "date_first_purchase": None} {"object_id": 1, "date_purchase": "2018-2-10", "date_first_purchase": "2018-2-2"} Below are my Django models: class Object(models.Model): object_id = models.IntegerField(unique=True) date_first_purchase = models.DateField(null=True) date_most_recent_purchase = models.DateField(null=True) # this second model is not very important here class Purchase(models.Model): purchase_id = models.IntegerField(unique=True) date_purchase = models.DateField(null=True) (For a given object_id, I have many purchases) I would like to define some rules: if for a given object_id, there is no date_most_recent_purchase (= null) in DB, but a date_first_purchase in the dictionary (such as {"object_id": 1, "date_purchase": None, "date_first_purchase": "2020-11-11"}), we should set the value of date_first_purchase in DB for field date_most_recent_purchase. We should apply the same logic in the other case: date_first_purchase is null in DB, and dictionary contains a value such as {"object_id": 1, "date_purchase": "2019-12-12", "date_first_purchase": None} If date_first_purchase is set in DB, but the dictionary contains a value with a lower value of date_first_purchase, we … -
How to create multiple objects using django formset

Djagno rest view file structure with complex calculations
I'm writing django rest api. I'll be taking form which will be sent from frontend. Form will contain data which I'll be using for performing calculation. But there is a problem. Based on form data code should execute different calculation types. So for example form { "type": 1, "form": 3, "method": } Then I should read "type". It should lead rest of form to another View method called for example type1. Then using "form" it should go for another view method form3 etc. Should I write that long api views methods or maybe I should create another file for performing calculations based on form data? Example (I will not attach serializer validation etc there): class SubmissionView(APIView): def post(self, request): if request['type'] == 1: self.type1(request.data) elif request['type'] == 2: self.type2(request.data) ........ def type1(self, request_data): if request['form'] == 1: self.form1(request.data) elif request['form'] == 2: self.form2(request.data) etc... -
Create Django URL inside JS function based on 3 different models
I have a function that displays titles from 3 different models in Django. I want to add a link to each title so it redirects the user to the proper URL. The search_autocomplete function returns all titles properly in 1 list, however, I am struggling with the creation of the URL address in the js file. I am using this library to create a list of titles. Let's say that the user puts "python is amazing" in the search bar. The URL address should contain rootURl/modelUrl/slug. If the title comes from the article model then it should look like this: http://127.0.0.1:8000/article/python-is-amazing If the title comes from the qa model then it should look like this: http://127.0.0.1:8000/qa/python-is-amazing If the title comes from the video model then it should look like this: http://127.0.0.1:8000/video/python-is-amazing The second issue is that I want to display a list of titles in autocomplete list but I need to pass the slug field to the URL address. How can I do that? js file //root URL const rootUrl = 'http://127.0.0.1:8000' //models URLs const articleURL = 'article' const qaURL = 'qa' const videoURL = 'video' new Autocomplete('#autocomplete', { search: input => { const url = `/search/?title=${input}` return new Promise(resolve … -

How to handle Firebase Cloud Messaging Notifications in Django?
I am managing to send FCM notifications to my app through Django. Here is my function for pushing notifications: import firebase_admin from firebase_admin import credentials, messaging cred = credentials.Certificate("service-key.json") firebase_admin.initialize_app(cred) def send_push(title, msg, registration_token, dataObject=None): try: message = messaging.MulticastMessage( notification=messaging.Notification( title=title, body=msg, ), data=dataObject, tokens=registration_token, ) response = messaging.send_multicast(message) except messaging.QuotaExceededError: raise f'Exceeding FCM notifications quota' Now, I'll be sending a Notification inside a view: class AdminChangeRole(viewsets.Viewset): serializer_class = SomeSerializer permission_classes = [IsAdminOnly] def post(self, request, *args, **kwargs): # code that will change the role of a user send_push("Role changed", f"You role was set to {self.role}", fcm_registration_token) # return Response Now, after posting some data inside a serializer and save it. I'm hoping to send a notification for a User. However, I want to know if I am handling this correctly, including the 2500 connections in parallel and 400 connections per minute. -
ConsumptionClient reservations_summaries.list error of MissingSubscription
Package Name: ConsumptionManagementClient Package Version: 9.0.0 Operating System: IOS Python Version: 3.7 Describe the bug After updating the creds for app registration as described here: https://docs.microsoft.com/en-us/azure/role-based-access-control/built-in-roles#cost-management-reader I am facing the same error: '(MissingSubscription) The request did not have a subscription or a valid tenant level resource provider. Code: MissingSubscription Message: The request did not have a subscription or a valid tenant level resource provider.' To Reproduce Steps to reproduce the behavior: from azure.mgmt.consumption import ConsumptionManagementClient credentials = retrieve_creds() subscription_id = 'XXXXXXXXXXXXXXX' consumption_client = ConsumptionManagementClient( credentials, subscription_id, 'https://management.azure.com' ) scope = subscription_id reservation_generator = consumption_client.reservations_summaries.list(scope=scope, grain='monthly') for reservation in reservation_generator: print(reservation) Expected behavior I expected that in subscription_id which has the required creds, I will be able to loop on the reservation summary result. but it failed in the loop. Additional context It is pretty hard to find good documentation for consumption_summary package. If I did something wrong in the code, please reference me to relevant resource. Just to mention that consumption_client.usage_details.list(scope, filter=date_filter) worked fine.
