How to pass error logging parameters in python django as a wrapper function and use it for every method?
I am using Django-DB-logger for capturing my error logs in every method.I have multiple logging parameters----> user, class_name, method_name, module_name, ip_address, process_time. I need to get logs from every method. Given below is a sample method where I used my logging parameters. import logging import sys import socket import time from django.shortcuts import render from django.urls import resolve from rest_framework import status, request from rest_framework.decorators import api_view from rest_framework.response import Response from rest_framework.views import APIView class Request(APIView): @api_view(['GET']) def test_api_method(self): startTime = time.time() print('This is Test API') db_logger = logging.getLogger('db') try: 1 / 0 except Exception as e: endTime = time.time() db_logger.exception(e, extra={'user': self.user.username, 'class_name': self.__class__.__name__, 'method_name': sys._getframe().f_code.co_name, 'module_name': __package__, 'ip_address': socket.gethostbyname(socket.gethostname()) 'process_time': endTime - startTime}) return Response({'data': True}, status=status.HTTP_200_OK) Rather than using all the parameters in every method like above, I want to use to decorator/ wrapper class (in a separate .py file) so that I can just call that decorator every time for capturing parameters during exception handling in all the methods in different .py files. Kindly reply soon. -
POST method does not pass the value password from the input field
Here form is submitted via POST method but password given in the input field of type=password not assigning to 'upassword' given in the userregister function.When I print the 'upassword' it gives an output "None".Also it gives an error like this when I give JAVASCRIPT validation.

400 bad request during axios call
Not sure why but the POST request is coming back 400. Postman says my django backend is doing fine. It all happens at the post_flashcards method any help would be great and I am willing to show any other code as requested. although there shouldnt be the need to since this component acts mostly on its own. class CreateFlashCard extends Component { constructor(props) { super(props); this.state = { title: '', collection_id: '', term: '', definition: '', } this.handleSubmit = this.handleSubmit.bind(this) } onChange = (e) => { this.setState({[e.target.name]: e.target.value}); } handleSubmit(e) { e.preventDefault(); this.post_flashcard() } async post_flashcard() { const card = this.state; const col_id = parseInt(this.state.collection_id) try{ await axios.post(`http://127.0.0.1:8000/flashcardsapp/${col_id}`, card) .then(response => console.log(response.status)) }catch(er){ console.log('ERROR in post_flashcard', er) } } render() { const {title, collection_id, term, definition} = this.state return ( <form onSubmit={this.handleSubmit}> <h2>Create a Card</h2> <label for="title">Enter Collection Title</label> <input type="text" name="title" value={title} onChange={this.onChange} ></input> <label for="collection_id">Enter Collection ID</label> <input type="number" name="collection_id" value={collection_id} onChange={this.onChange} ></input> <label for="term">Enter Term</label> <input type="text" name="term" value={term} onChange={this.onChange} ></input> <label for="definition">Enter Definition</label> <input type="text" name="definition" value={definition} onChange={this.onChange} ></input> <input type="submit"></input> </form> ); } } export default CreateFlashCard; -

Duplicate in Object storage
I use a Minio-backend in the Django app. I have a feature that users can use the object storage(user online gallery), and Also, users can upload a new image from the device to create a post. But when I use the object storage images and create an image, images duplicate in object storage(because each time I create a post, I want to upload new images( images that upload locally) in object storage). What should I do to prevent these duplicates? It is my model: class MediaStorage(models.Model): file = models.FileField(verbose_name="Object Upload", storage=MinioBackend(bucket_name='django-backend-dev-private'), upload_to=iso_date_prefix) this is my create new post : class CreatePostView(generics.CreateAPIView): ... def post(self, request, *args, **kwargs): user = request.user data = request.data ... for media_file in post_files: file_team=post_team f = MediaStorage.objects.create(team=file_team,owner=user) f.media=media_file f.save() post.multimedia.add(f) return Response(post_serializer.PostSerializer(post).data, status=status.HTTP_201_CREATED) Thank you so much. -
DRF Updating model's CharFiled with choices doesn't do anything
I have a Task app in my django project. So this is the base class for the task model: TASK_STATUSES = [ ("DN", "Done"), ("IP", "In progress"), ("IR", "In review"), ("NW", "New"), ("RJ", "Rejected"), ("TD", "To do"), ] class TaskBase(models.Model): STATUS_CHOICES = TASK_STATUSES status = models.CharField("State", max_length=2, default="NW", choices=STATUS_CHOICES) [...] class Meta: abstract = True This is the actual model: class Task(TaskBase): TYPE_CHOICES = TASK_TYPES type = models.CharField("Type", max_length=1, default="T", choices=TYPE_CHOICES) project = models.ForeignKey(Project, on_delete=models.CASCADE) Serializer: class TaskSerializer(serializers.ModelSerializer): status = serializers.CharField(source="get_status_display") class Meta: model = Task fields = "__all__" And the viewset: class TaskViewSet(viewsets.ModelViewSet): queryset = Task.objects.all() serializer_class = TaskSerializer lookup_field = "name" permission_classes = [] authentication_classes = [] Now I update the task's status via PATCH request to /api/task/<task_name>/ with {"status": "TD"}. So the response is "PATCH /api/task/XYZ/ HTTP/1.1" 200 233 - everything is fine, I receive "TD" in the response data - the status changed. But when I get the task again, it still has his previous status ("New").

Overriding the save method for all the models in Django
I want to override the save method for all the models in my application. It can be easily done by using inheritance class MyModel(models.Model): def save(*args, **kwargs): # Do something here... super().save(args, kwargs) class User(MyModel): .... The problem with this approach is that this will need a change in the already defined models. Also, models defined in the external libraries will also need to be taken care of separately. Is there a better way to do it? -

Twitter/Reddit posts not embedding properly on Django template
I'm building a news aggregator. I am connected to the twitter and reddit APIs through the tweepy and PRAW libraries. I'm pulling json data from twitter and reddit, and displaying posts in a timeline format side by side. I have one template called main.html which takes in context(reddit post ids; twitter status urls) and passes that context to template tags, in order to generate html to embed.

How to remove old form to stop double-submission
I am using AJAX to submit a form from a modal window. If the form is submitted with errors the server will send back a new form. The container holding the old form is then removed and the new form, with validation errors, is set in it's place. The issue is that, for some reason, it submits 2 forms at the same exact time after the validation errors are fixed. It is as-if the old form does not get removed? It does not happen when I use the onclick=functionCall() syntax but rather when I use the $('form').on('submit', e => { syntax. I am trying to use the latter as I was told the onX events are now considered bad practice. Any help on understanding what is happening and how to fix it would be useful. Form: // Submit Form $('form').on('submit', e => { e.preventDefault(); let data = new FormData($(e.target).get(0)); const btn = $(e.target).find('button:submit') const container = document.getElementById('formFields') $.ajax({ url : e.target.action, data : data, type : 'POST', headers : {"X-CSRFToken": token}, enctype : 'multipart/form-data', processData : false, contentType : false, success : function (data) { btn.toggleClass('btn-warning btn-secondary').prop('disabled', true) }, error : function (data) { container.innerHTML = loadingSpinner; $(container).empty(); $(container).html(data['responseJSON']['table']).fadeIn('slow'); }, … -
Django's SECRET_KEY for Two Computers
I am new to Django(3.2) and learning from Django Website's tutorial using two computers. Recently I learned how to use python.decouple module and .env to keep SECRET_KEY locally. But the thing is that I am using two computers and github to work on a project. So each computers are currently holding locally different SECRET_KEY. For now, pulling and pushing works, but this made me think about what might cause problem if I keep developing this project in this way. So I found this post, but it is about the project on service. I tried to search on stack overflow and google, but I found no similar situation as mine. (Does this indicate that I should the same SECRET_KEY? But why?) Since this question might sound too broad, to narrow it down a bit, I would say that my question is 'Will using two different SECRET_KEY's for a project cause problem? What are some problems with most impact?' Thank you in advance for your help. -

ASPBookings field dates 2021-05-27 2021-06-24 2021-06-15 Today's date 2021-06-09 Thanks in advance for any help I can get on this. -
Conditionally Access and Direct User in Django Class-Based View
I have a Django custom form classed-based view. Under normal conditions I want it to be accessible to both authenticated and logged out or anonymous visitors. However, under certain conditions I'd like it to alert the user they need to login to submit the form (and redirect them). Example: class CustomFormView(FormView): ... def form_valid(self, form): user = self.request.user req_id = self.request.GET.get("req_id") if req_id: errors = False if not user.is_authenticated(): messages.error(self.request, "You must be logged in to fill out this form. Please sign in, then visit this link again.") errors = True # redirect try: ... if errors: ctx = self.get_context_data() return self.render_to_response(ctx) I'm aware of LoginRequiredMixin (docs) as well as a decorator @method_decorator(login_required) but I don't want to apply it at the view level or to the entire form_valid() function, only check login state when if req_id condition is met. Currently the view's not executing my if not user.is_authenticated(): so my attempt isn't correct. Is there a way to accomplish this within form_valid()? thanks -
Django QuerySet .count() is 0 and .exists() is false, even though there's an object in the QuerySet (Django Rest Framework)
I've had an intermittent bug for months and I am stuck! Help is appreciated. @receiver(models.signals.post_delete, sender=ContentFile) def delete_file(sender, instance, *args, **kwargs): class ContentFile(models.Model): """ Represents the metadata for a single document. """ name = models.CharField(max_length=200) set = models.ForeignKey(Set, related_name='contentfile_set', on_delete=models.CASCADE) location = models.FileField(upload_to=get_content_file_upload_path) class Meta: app_label = 'ProtocolManager' unique_together = ('set', 'location') def __str__(self): return f"File {self.name} at location {str(self.location)} attached to {self.set}" """ Delete orphaned file once last ContentFile is removed. """ log.info(f"Checking {instance.location} for existing ContentFile") if instance.location: from django.db import connection from django.db import reset_queries reset_queries() files_queryset = ContentFile.objects.filter(location=instance.location) if not files_queryset.exists(): log.info(f"ContentFile does not exist for {instance.location}, deleting...") log.info(f"SQL: {connection.queries}") log.info(f"files_queryset: {list(files_queryset.all())}") log.info(f"count: {files_queryset.count()}") log.info(f"exists: {files_queryset.exists()}") instance.location.delete(save=False) The logic is pretty simple. When a ContentFile row is deleted, if it was the last one referring to an actual file location, we delete the file itself (on AWS S3, if it matters). 99% of the time this works as expected, but sometimes it will fail, and when it fails, it seems to fail for all of the ContentFiles associated with a given Set. I added the verbose logging to try to get more clues, but today it finally reproduced for the first time in months and the …
