Django ConnectionAbortedError
So I am trying to solve api issue. I am making request to django backend using axios from my frontend application. They are running on seperate domains. My django app is running in a virtual environment. If I make a request using postman I will get my response no problem but if I make request using my front end application I get the following error. Traceback (most recent call last): File "c:\laragon\bin\python\lib\socketserver.py", line 650, in process_request_thread self.finish_request(request, client_address) File "c:\laragon\bin\python\lib\socketserver.py", line 360, in finish_request self.RequestHandlerClass(request, client_address, self) File "c:\laragon\bin\python\lib\socketserver.py", line 720, in __init__ self.handle() File "C:\Users\Thomas\.virtualenvs\qb_project-vSd1QFH0\lib\site-packages\django\core\servers\basehttp.py", line 174, in handle self.handle_one_request() File "C:\Users\Thomas\.virtualenvs\qb_project-vSd1QFH0\lib\site-packages\django\core\servers\basehttp.py", line 182, in handle_one_request self.raw_requestline = self.rfile.readline(65537) File "c:\laragon\bin\python\lib\socket.py", line 589, in readinto return self._sock.recv_into(b) ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine This is the axios method axios.get('http://mybackend/api/oauth') .then(response => { context.commit('CONNECTION', response) console.log(response) resolve(response) }).catch(error => { console.log(error) reject(error) }) and this is my method for returning my response urls.py urlpatterns = [ path('api/oauth', oauth, name='oauth') ] api.py @api_view(['GET']) def oauth(request): auth_client = AuthClient( settings.CLIENT_ID, settings.CLIENT_SECRET, settings.REDIRECT_URI, settings.ENVIRONMENT ) data = auth_client.get_authorization_url([Scopes.ACCOUNTING]) request.session['state'] = auth_client.state_token return Response(data) So for some reason the connection is being closed, before the … -
Unable to save my admin.py changes in my model

How to loop through millions of Django model objects without getting an out of range or other error
I have millions of objects in a Postgres database and I need to send data from 200 of them at a time to an API, which will give me additional information (the API can only deal with up to 200 elements at a time). I've tried several strategies. The first strategy ended up with my script getting killed because it used too much memory. This attempt below worked better, but I got the following error: django.db.utils.DataError: bigint out of range. This error happened around when the "start" variable reached 42,000. What is a more efficient way to accomplish this task? Thank you. articles_to_process = Article.objects.all() # This will be in the millions dois = articles_to_process.values_list('doi', flat=True) # These are IDs of articles start = 0 end = 200 # The API to which I will send IDs can only return up to 200 records at a time. number_of_dois = dois.count() times_to_loop = (number_of_dois / 200) + 1 while times_to_loop > 0: times_to_loop = times_to_loop - 1 chunk = dois[start:end] doi_string = ', '.join(chunk) start = start + 200 end = end + 200 [DO API CALL, GET DATA FOR EACH ARTICLE, SAVE THAT DATA TO ARTICLE] -

Django/DRF - Serialize Queryset avoiding N+1 problem with SerializerMethodField
I am using this model configuration. class Project(models.Model): name = models.CharField(max_length=64) class Platform(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE, related_name="project_platforms") is_deleted = models.BooleanField(default=False) Now, I am getting my queryset using this code. queryset = Project.objects.prefetch_related("project_platforms") I want to serialize this queryset using the following Serializer. class ProjectSerializer(serializers.ModelSerializer): platforms = serializers.SerializerMethodField("_platforms") class Meta: model = Project fields = ["id", "name", "platforms"] def _platforms(self, obj: Project) -> list: platforms = PlatformSerializer(obj.project_platforms.filter(is_deleted=False), many=True).data return platforms Now, even though I have used prefetch_related, when I call the serializer on my queryset, it still causes one query for each project in fetching the platforms for each project. I cannot use platforms = PlatformSerializer(read_only=True, many=True) since the PlatformSerializer is declared below ProjectSerializer. Is there any solution to this? Am I doing something wrong? -
How to preload a video in Django
This is an online experiment program in Django. In the playing page I got: Playing.html <video height="50%" autoplay id="video" {{video_muted|safe}}> <source src="{% static path %}" type="video/mp4"> </video> The videos are just 1-5MB, however, some users' Internet speed is so slow. Sometimes it takes them 2 minutes to load/download a video. Any method I can transfer the videos to users browser first and then in the playing.html, it gets the video from "cache in local browser" instead of the server directly. Thanks in advance. -
Checking in def clean to see if image field has been cleared
Within my def clean function, I've built a check to see if a user has an image, but no body, which is an invalid combination. forms.py def clean(self): cleaned_data = super(ServicesForm, self).clean() body = cleaned_data.get('body ') image = cleaned_data.get('image') if body != None and image == None : self.add_error('image', "You must provide an image if you want to save the post.") This works well upon the creation of the post. The error shows up if the user enters text in the body, but doesn't provide an image. However, if a user goes back to a post where both a body and image have been provided and clicks on 'clear' on the image widget, they are able to save the form with no error being thrown. Due to other reasons, I do not want to set image as a required field on this form. (There is other business logic that controls whether or not an image is required or not). How can I check in def clean() to see if the user has cleared the image? Thanks! -
How to disable loggin in pyppeteer
I'm using pyppeteer to take screenshots of images to a make a pdf but pyppeteer auto logs everything I take a screenshot at and because of server limitations and the logs is written to a file the logs are crashing my server.

Puzzling Warning With FileField In Django Admin
I created the below model to associate a file with another object type called Organization. The _path() function sets the path of the file to {MEDIA_ROOT}/orgs/{NAME OF ASSOCIATED ORG}/{FILENAME}. It also replaces any spaces in the path with underscores. So if I upload the file "Draft1.doc" and associate it with the org named "My High School", the full path should be uploads/orgs/My_High_School/Draft1.doc This is in my settings.py file MEDIA_ROOT ='uploads/' class OrgFile(models.Model): def _path(instance, filename): return F"orgs/{instance.org.name.replace(' ', '_')}/{filename}" file = models.FileField(upload_to=_path) org = models.ForeignKey(Organization, on_delete=models.DO_NOTHING) def __str__(self): return self.file.name.split('/')[-1] When I use the Admin to upload and associate a file, the file is created in the correct place on disk and appears to have the correct path and associations in the admin. However when I navigate to the file object in the admin and click on the path labeled currently the "uploads/" portion is not included in the path (which may be OK) but I also get the warning: Org file with ID “9/change/orgs/My_High_School/Draft1.doc” doesn’t exist. Perhaps it was deleted? I have no idea why this happens since everything else looks OK. I assume that the link is supposed to take me to the file. -

Django - urls.py issue
I am developing this platform where a user can log in and take a quiz. The issue is that when I go on "localhost/quiz/quiz/" and then a click on my "choice", for example "data science" it gives me this error: sing the URLconf defined in piattaforma.urls, Django tried these URL patterns, in this order: admin/ [name='homepage'] users/ [name='user_list'] user/<username>/ [name='user_profile'] accounts/ accounts/ quiz/ quiz/ [name='quiz'] quiz/ questions/<choice>/ [name='questions'] quiz/ result/ [name='result'] The current path, quiz/datascience, didn't match any of these.

django: drowning in login form/view

I have tried using the built-in authentication system but I failed to make it work with django-tenant. At this point, my login view "works" but does not do its job.

Update django-dash dashboard with new dataframe data in a Django app
Our Aim We're creating a time series plot in a Django app using dash/plotly. The data being plotted is read from a pandas dataframe which is first pre-processed written to a file, and then sent to the next page via POST request for the interactive dashboard. On updating the dataframe the new plot should be plotted on the dashboard. Problem Even though the data is changed the dashboard doesn't updates. It still shows the plot for the previous dataframe saved in the file. Until or unless the django server is restarted it doesn't updates. dcc.interval() doesn't do the trick, it also requires the server to be restarted even though you can see the dash app reply in the console log plus it removes the zoom in capability for a graph since, it refreshes the plot. The Django version in use is 2.2.9 Here is the django-dash app code: import dash_core_components as dcc import dash_html_components as html from dash.dependencies import Input, Output,State import plotly.graph_objs as go from django_plotly_dash import DjangoDash import pandas as pd import dash_table from datetime import datetime app = DjangoDash('chalao') selected_df=pd.read_pickle(r'static/selected_df.pkl') actual_df=pd.read_pickle(r'static/actual_prediction.pkl') datatable_df=actual_df datatable_df.reset_index(inplace=True) datatable_df['START_DATETIME'] = datatable_df['START_DATETIME'].astype(str) datatable_df['Transaction'] = datatable_df['Transaction'].round(decimals=-3) datatable_df['Prediction'] = datatable_df['Prediction'] + 500 datatable_df['Prediction'] = datatable_df['Prediction'].round(decimals=-3) … -

Cloud Build env variables not passed to Django app on GAE
I have a Django app running on Google AppEngine Standard environment. I've set up a cloud build trigger from my master branch in Github to run the following steps: steps: - name: 'python:3.7' entrypoint: python3 args: ['-m', 'pip', 'install', '--target', '.', '--requirement', 'requirements.txt'] - name: 'python:3.7' entrypoint: python3 args: ['./manage.py', 'collectstatic', '--noinput'] - name: 'gcr.io/cloud-builders/gcloud' args: ['app', 'deploy', 'app.yaml'] env: - 'SHORT_SHA=$SHORT_SHA' - 'TAG_NAME=$TAG_NAME' I can see under the Execution Details tab on Cloud Build that the variables were actually set. The problem is, SHORT_SHA and TAG_NAME aren't accessible from my Django app (followed instructions at https://cloud.google.com/cloud-build/docs/configuring-builds/substitute-variable-values#using_user-defined_substitutions)! But if I set them in my app.yaml file with hardcoded values under env_variables, then my Django app can access those hardcoded values (and the values set in my build don't overwrite those hardcoded in app.yaml). Why is this? Am I accessing them/setting them incorrectly? Should I be setting them in app.yaml somehow? I even printed the whole os.environ dictionary in one of my views to see if they were just there with different names or something, but they're not present in there. -
