loggly-python-handler with django dosent send the logs to loggly
i have django app (Django-Rest-Framework) and i want to add integration with Loggly via HTTP. i used the library loggly-python-handler but the logs are not sent to Loggly. i followed the docs: https://www.loggly.com/docs/python-http/ i installed loggly-python-handler i added to django setting.py file the following: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s' }, 'simple': { 'format': '%(levelname)s %(message)s' }, 'json': { 'format': '{ "loggerName":"%(name)s", "timestamp":"%(asctime)s", "fileName":"%(filename)s", "logRecordCreationTime":"%(created)f", "functionName":"%(funcName)s", "levelNo":"%(levelno)s", "lineNo":"%(lineno)d", "time":"%(msecs)d", "levelName":"%(levelname)s", "message":"%(message)s"}', }, }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'level': 'DEBUG', 'formatter': 'verbose', }, 'loggly': { 'class': 'loggly.handlers.HTTPSHandler', 'level': 'INFO', 'formatter': 'json', 'url': 'https://logs-01.loggly.com/inputs/TOKEN/tag/python', }, }, 'loggers': { 'django': { 'handlers': ['console', ], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), }, 'APPNAME': { 'handlers': ['console', 'loggly'], 'level': 'INFO', }, }, } i changed the TOKEN to my token in my app, in views.py, i called the logger: import logging logger = logging.getLogger(name) logger.info('this is INFO message.') i use Fiddler to see all HTTP requests, but i didn't see any request sent to loggly url. when i call it directly with curl it works. curl -H "content-type:text/plain" -d '{ "message" : "hello" }' http://logs-01.loggly.com/inputs/61fd261c-062f-44b1-b866-f03f5d50f720/tag/http/ -
Django signal based on the datetime field value
I'm struggling with the following. I'm trying to create a custom signal that will trigger when the current time will be equal to the value of my model's notify_on DateTimeField. Something like this: class Notification(models.Model): ... notify_on = models.DateTimeField() def send_email(*args, **kwargs): # send email signals.when_its_time.connect(send_email, sender=User) After I've read through all docs and I found no information on how to implement such a signal. Any ideas? -
How to add to a view of a Django installed app?
An external app provides functionality for uploading a certain type of data via my application using template/view/form. This works great. In the view for upload, it performs a check: if request.method == GET: <handle GET> elif request.method == POST: form = UploadForm(request.POST, request.FILES) <handle POST> In the 'handle POST' part of the view, I want to add something that says if a checkbox I have added to the upload template is checked, I want to upload the data in a custom way using my own model etc. If the checkbox isn't checked, just use the current upload code as is. To do this I figured I'd need to edit the upload view from the external app, as well as maybe adding my model to the models.py of the external app, but I know that's not how you're supposed to work. I thought about adding my own app with this functionality in it (model etc.) and I imagine that'll be fine, but I'd still need to add this conditional to the original view, which means editing the external app code again. How should I do this? -
Active Django app do not recognize global $PATH
I have deployed Django project (coded in Windows) on Ubuntu 18.04 server with gunicorn and nginx. There is a view which call in command line external package executable, located in /home/user/blast/bin/. PATH to package is defined in .profile export PATH="$PATH:/home/user/ncbi-blast-2.8.1+/bin" Package PATH is seen in echo $PATH also in my django project virtualenv. /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/ka4an/ncbi-blast-2.8.1+/bin I am able to run package executable in some_script.py in main shell and in django virtualenv like this: subprocess.run("package_executable", shell=True, stdout=log_file, stderr=log_file) and it returns expected output. However, when It is run in active Django app through views.py it returns that package_executable is not found. I found that inside active Django app i have different echo $PATH output, without PATH to my package: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin Active Django app is run by the same root user (who - returns same user). I can run my package inside active Django app by providing full path to package executable, but i`m interested in why Django do not recognize $PATH in .profile. -
Django - Extend the User model with different user kind
I want to extend the user model in Django (2.2) and combine it a Host and a Guest entities that have also specific fields. In the official documentation, it is recommended to create a "Profile" class with a OneToOne field that reference the User primary key. I can see 3 ways of doing it: Solution 1: Profile, Host and Guest model: class Profile(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) language = models.CharField(max_length=2) class Host(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) description = models.CharField(max_length=500) class Guest(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) have_car = models.BooleanField(null=False) Solution 2: Host and Guest model (with Profile fields duplicated) class Host(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) language = models.CharField(max_length=2) description = models.CharField(max_length=500) class Guest(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) language = models.CharField(max_length=2) have_car = models.BooleanField(null=False) Solution 3: Profile model (containing Guest and Host fields) class Profile(models.Model): k_user = models.OneToOneField(User, on_delete=models.CASCADE) language = models.CharField(max_length=2) is_host = models.BooleanField(null=False) have_car = models.BooleanField(null=False) description = models.CharField(max_length=500) All those solutions are working. My question is: "Which one is the smartest, all things considered" (less database access, less code to write, easier to maintain, less limitations, etc..) -

How I can test if user have permission for view
I created permission for my view, and its work but I dont know how I can test if patch request will work with user without permission. permission.py class IsObjectCreator(permissions.BasePermission): def has_object_permission(self, request, view, obj): if request.method in permissions.SAFE_METHODS: return True return request.user == obj.user views.py class TaskDetailAPIView(APIView): permission_classes = [IsObjectCreator] def get_object(self, id): try: return Task.objects.get(id=id) except Task.DoesNotExist: raise Http404 def get(self, request, id): task = self.get_object(id) serializer = TaskSerializer(task) return Response(serializer.data) def patch(self, request, id): task = self.get_object(id) serializer = StatusSerializer(task, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) In normal Django view I can check if response contain form, but I dont know how in API I can test if response contain patch method. -
Bug regards Django adds extension/folder name to image stored on AmazonS3
I have a major bug in production, my image file extension keeps adding another folder on AmazonS3. An example is posted below. I just defined a regular image field in my model.

Do some post-processing after form submit, and render a new page with the newly processed data
Django newbie here, I created a simple form following this tutorial, and my form correctly saves the data in my Postgres connected local database. Then I used a signal to trigger on post_save so I can run my custom code. I learned by this question. Now, after the user enters data in the form and it gets saved, which triggers the custom code which does some post-processing, I want to show the user a new page with the newly processed data. But the trigger function I have used does not let me pass arguments to the custom code function. Before this, I was able to show the user the new page with some sample data and render a page with the new data. But, now I want to do it only when a user enters some data. Is this the right approach ? My templates all work fine, and the custom code fills the variables like rocode.vehicleroute with string values. Here is my code : views.py from django.shortcuts import render from django.http import HttpResponse from .forms import auditform, ClientAuditForm from django.db.models.signals import post_save from .models import auditModel def clientauditingfun(request): if request.method == 'POST': forminput = ClientAuditForm(request.POST) if forminput.is_valid(): Preference = … -

Django Visitor Uploaded directory with uuid and sending the id to custom Script
I am creating a Django application that will convert the image to text. The script working fine before I add upload_to= in my model. Have a look at my model.py from django.db import models import os import uuid from django.conf import settings def img_path(_, file_name): return os.path.join(settings.MEDIA_ROOT, str(uuid.uuid4()), file_name) class ImageForExtractText(models.Model): image = models.FileField(upload_to=img_path) When a visitor uploads an image, it creates a new directory and put the image there. even if the same visitor uploads another image, it creates another new directory and put that image there---- this is working nice, no issue with this. Problem with my OCR script, the script can't find the image directory, coz, it always creates a new directory name with uuid. Have a look at img2text.py below import os import pytesseract from PIL import Image def extract_text_from_img(): basepath = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) basepath = basepath[:-5] + '/media/' img_path_list = os.listdir(basepath) for path in img_path_list: path = basepath + path img = Image.open(path) text = pytesseract.image_to_string(img) yield text This script can't find the directory name. It should always recognize the unique visitor uploaded image directory.

Django user signup using custom user model not workin

Is there a way to create a Task Manager Django App?
I wish to create a Task Manager Django app that can allow a user to sign in and new users to sign up. I've already done that part. A signed-in user can create a 'Team' and can add other users to his team. Now I want a message to be sent to the added users, saying like : 'Hey, you have been added to the Team of xyz User'. How to intercommunicate ? Is there something like an FB friend request possible here ? A signed-in user can create and assign a 'Task' to a single 'Team' but he may or may not assign it to the entire team, i.e. he can choose some members of a team and reject others, but all this must be from a single team. How to manage this ? Another issue is that once the user has signed in, he can only view the teams that he has created and also those teams to which he has been added. He must not view 'all' the created teams. I'm an infant to Django and I need to submit this project. Please help. Thanks a lot ! I've done the sign-in and sign up part. models.py … -

Django - Annotating each Event with Sum of participants that overlap with the start DateTime of that Event
I have an Event model with a start DateTime and end DateTime, as well as the number of participants. For each Event object, I want to get an annotated Sum of ALL the participants in any event that overlaps with the start DateTime. This is so I can make sure there aren't too many participants at any given time. class Event(models.Model): start = models.DateTime() end = models.DateTime() participants = models.IntegerField() I've been reading about Window functions, and maybe that would work here, but I can't get it right. I tried this, but it doesn't work because it's looking to group together events with the SAME start DateTime, not overlapping periods of start and end DateTimes against the original event start DateTime. starts = Event.objects.annotate( participants_sum=Window( expression=Sum('participants'), partition_by=[F('start'),], order_by=ExtractDay('start').asc(), ), ).values('participants', 'participants_sum', 'start') Any recommendations would be appreciated! -

Custom validation in ModelSerializer not working
I have a model of Printer: class Printer(models.Model): name = models.CharField(...) api_key = models.CharField(...) check_type = models.CharField(...) point_id = models.IntegerField() I created several printer objects.
