Difference between Apache process and WSGI process?
I have a Django application running with Apache prefork (my code is not thread safe). I am relatively new to Apache, so apologies in advance if this is too basic. As far as I understand the main differences are: Apache process: control access and serve static files WSGI process: execute python code Does this mean that if I define MaxRequestWorkers in Apache as 250, and wsgi processes = 10.. each one of the 250 Apache processes can fork into another 10 processes? Also, according to mod_wsgi documentation sites using Apache prefork should set the wsgi threads = 1 My site actually works when setting wsgi threads = 5 with Apache prefork. But doesn't work with Apache worker since the code is not thread safe... How can this be? -
Heroku unable to verify card
I wanted to connect my custom domain to django website hosted on heroku because it was free, I wanted to connect my domain to heroku but it asks for verification, I tried to add my card and I also added all things correctly but it gives unable to verify card error, I tried with different card also but it gives same error, There is no fault of card, Is there any other solution to it, Is there any hosting that allows to host django website for free and also allows to add custom domain like heroku instead of digital ocean and amazon aws. -

Logger emit() is called multiple times for a single request
I am trying to modify the emit() of logging. handler such that I can ship the logs to my Kafka broker. However, I am noticing something strange, every time I make a request, the emit() is called multiple times. E.g When I go to the browser and press enter once, the emit() is called once, and then when I retry the request, the emit() is called twice. The trend is that the calls to emit() increases linearly with every request. Tried debugging through the logs but couldn't find any errors. Any suggestion or advice would be really appreciated. handler.py from logging import StreamHandler from ..mykafka import MyKafka class ErrorLogHandler(StreamHandler): def __init__(self, broker, topic): StreamHandler.__init__(self) self.broker = broker self.topic = topic # Kafka Broker Configuration self.kafka_broker = MyKafka(broker,True) def emit(self, record): data = { 'sys_name': 'Test', 'logger_name': record.name, 'level': record.levelname, 'message': record.msg, 'function_name': record.funcName, 'file_name': record.filename, } self.kafka_broker.send(data, self.topic) mykafka.py from kafka import KafkaProducer import json class MyKafka(object): def __init__(self, kafka_brokers, is_json=False): self.is_json = is_json if not is_json: self.producer = KafkaProducer( bootstrap_servers=kafka_brokers ) else: self.producer = KafkaProducer( value_serializer=lambda v: json.dumps(v).encode('utf-8'), bootstrap_servers=kafka_brokers, ) def send(self, data, topic): if self.is_json: result = self.producer.send(topic, key=b'log', value=data) else: result = self.producer.send(topic, bytes(data, 'utf-8')) print("kafka send … -
Django Nested model or serializers
I'm new in Django and I have a simple use case to parse a nested json file.

Django PayPal delay
I'm creating a payment system for a project I'm working on and I'm using django-paypal. I followed their guide and implemented the signals and everything is working correctly (user clicks on a button -> gets redirected to paypal -> if everything is good success page is shown). The thing is in my signals I have a thing where I want to give users points when the do the buying function. I have that in my signals but there is a delay between showing the success page and the actual signal receiving the data and being executed. I don't know if this is because I'm using stuff like ngrok and localtunnel or is it something else. This is my signals.py from paypal.standard.models import ST_PP_COMPLETED from paypal.standard.ipn.signals import valid_ipn_received, invalid_ipn_received from account.models import Account def show_me_the_money(sender, **kwargs): ipn_obj = sender if ipn_obj.payment_status == ST_PP_COMPLETED: if ipn_obj.receiver_email != "**": # Not a valid payment print("BAD EMAIL") else: print("ALL GOOD") acc = Account.objects.get(account_url=ipn_obj.custom) acc.coins = acc.coins + int(ipn_obj.mc_gross) acc.save() else: print("FAIL") valid_ipn_received.connect(show_me_the_money) So if I'm understanding everything this is all correct but for some reason the delay is happening and I don't know whats causing it. -
Django - Extending user profile not showing fileds in chenge form

Loading extra fields for update in Django dependent dropdown list
I implemented a dependent dropdown on my Django webapp. I used this tutorial Implementing dependent drop down. However, challenge comes when I want to update the form. To put this in perspective, let me recreate the code here. Model.py class VehicleMake(models.Model): make = models.CharField(max_length=20) manufacturer = models.CharField(max_length=20) def __str__(self): return self.make class VehicleModel(models.Model): make = models.ForeignKey(VehicleMake, on_delete=models.CASCADE) model_name = models.CharField(max_length=20) def __str__(self): return self.model_name class Vehicle(models.Model): model = models.ForeignKey(VehicleModel, on_delete=models.CASCADE) description = models.TextField() Notice that unlike in the provided tutorial, I don't have both of the dependent fields on the vehicle model. That is to avoid repetition since if you know the vehicle model, you will definitely know the make from the VehicleModel table. Here is the form: forms.py class VehicleDetails(forms.ModelForm): make = forms.ModelChoiceField(queryset=VehicleMake.objects.all(), empty_label="Select Vehicle Make") class Meta: model = Vehicle fields = ['make', 'model', 'description' ] def __init__(self, *args, **kwargs): super(VehicleDetails, self).__init__(*args, **kwargs) self.fields['model'].queryset = VehicleModel.objects.none() if 'make' in self.data: try: make = int(self.data.get('make')) self.fields['model'].queryset = VehicleModel.objects.filter(make=make).order_by('model_name') except (ValueError, TypeError): pass # invalid input from the client; ignore and fallback to empty VehicleModel queryset elif self.instance.pk: vehicle_model = VehicleModel.objects.get(self.instance.model) self.fields['make'] = vehicle_model.make self.fields['model'].queryset = self.instance.model_set.filter(make=vehicle_model.make).order_by('model_name') So, my challenge is, when I want to update the form, I get … -

django on IIS encounter 404 for media file with chinese character in filename
I deploy django on IIS. Everything is ok. But I encounter 404 when I download a media file with chinese character in filename. Page not found (404) Request Method: GET Request URL: http://localhost:8089/media/attachment/2021/02/%25B2%25E2.txt Raised by: django.views.static.serve "D:\Python\MrDoc\media\attachment\2021\02\%B2%E2.txt" Not exist. I know that %B2%E2 is URLencode with gb2312 of chinese character '测'. When the media file name contains only ASCII, such as 1.txt, no 404 and the file can be downloaded via browser. When I run server with "py manage.py runserver 0.0.0.0:8088", no 404 for media file name with chinese character. So the 404 problem is probably caused by the urlencode of IIS. I do not know how to solve this problem.
