Requested setting INSTALLED_APPS, but settings are not configured
I am working on a project for a while and now from nowhere I am getting this error: where the following seems to be the important part django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.co The error is coming when I am trying to use main.py The content (that is important for comprehension) of main.py is: I know about: export DJANGO_SETTINGS_MODULE=mysite.settings But this is not the solution for me. This problem only came when I add: from device.serializers.gcloud_device import GcloudDeviceSerializer If I do export the django_settings_module with the path to my settings.py then my error become: ImportError: cannot import name I do not have circular import. I already created a lot of apps in my project and this is the first time I see this error Thank you -
Utilizing django blob field to upload file to a blob column in Oracle
I want to upload files (images,pdf,ms word,etc) in the Oracle database (blob) using Django binary field. I need to store file name and file extension (e.g. png,jpeg,etc) and file size. However i can't figure out how to store in the blob field the binary data of the file. P.S. I know it's not best practise to store static files in the database but i have to do this. My Model: class File(models.Model): du_id = models.AutoField(primary_key=True) du_file = models.BinaryField() du_file_name = models.CharField(max_length=1000) du_file_extension = models.CharField(max_length=100) du_file_size = models.CharField(max_length=100) forms.py: from django import forms class UploadFileForm(forms.Form): file = forms.FileField(label='Upload document') html form: <form method="post" action="{% url 'images:upload' %}" enctype="multipart/form-data">{% csrf_token %} {{form}} <input type="submit" value="Upload file"> </form> view: from django.shortcuts import render from images.models import File from images.forms import UploadFileForm from django.http import HttpResponse, HttpResponseRedirect, JsonResponse from django.urls import reverse from django.utils.timezone import datetime import datetime,base64 def file_upload(request): if request.method == 'POST': form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): file_name = str(form.cleaned_data['file']) file_name_split = file_name.split('.') extension = file_name_split[-1].upper() test_string = "test string" res = bytes(test_string, 'utf-8') a = File.objects.create(du_file = res,du_file_name=file_name,du_file_extension=extension, du_file_size='1023') a.save() return HttpResponse(file_name) #return HttpResponseRedirect(reverse('images:home')) else: return HttpResponse('Form is not valid!') else: return HttpResponse('Failed') -
How to optimize deep nested foreignKeys in Django queryset
TLDR; Is there a better way to handle deep nesting in this Django queryset? File.objects.filter(folder__project__workspace__organization__in=user.organizations.all()) Detailed question: Here is an example scenario: An organization consists of multiple users and a user can be part of multiple organizations. class User(models.Model): pass class Organization(models.Model): members = models.ManyToManyField( User, through='OrganizationMembership', related_name='organizations' ) class OrganizationMembership(models.Model): member = models.ForeignKey(User) organization = models.ForeignKey(Organization) The nested relationship among models are defined as follows: class Workspace(models.Model): organization = models.ForeignKey(Organization, related_name='workspaces') class Project(models.Model): workspace = models.ForeignKey(Workspace, related_name='projects') class Folder(models.Model): project = models.ForeignKey(Project, related_name='folders') class File(models.Model): folder = models.ForeignKey(Folder, related_name='files') I wanted to filter all the files the requesting user has access to across organizations. Here is my queryset, is there a way to optimize this queryset? user = self.request.user organizations = user.organizations.all() File.objects.filter(folder__project__workspace__organization__in=organizations) -
Django Form Can't Filter Foreign Key on Dropdown
I have a "CustomUser" class that I got from an all-auth tutorial (Django All-Auth Tutorial) and I have user as a foreign key in each model, which works as intended, only showing records pertaining to the current logged in user to that specific user. For example: class Education(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) EducationInstitutionName = models.CharField(verbose_name=_('Institution Name'), max_length=100, default=None) EducationLevel = models.CharField(verbose_name=_('Education Level'), choices=EDUCATIONLEVEL, max_length=100, default=None) EducationStartDate = models.DateField(verbose_name=_('Education Start Date'), default=None) EducationEndDate = models.DateField(verbose_name=_('Education End Date'), default=None) EducationCaoCode = models.CharField(choices=CAO_CODE, max_length=100, default=None) EducationDesc = models.CharField(verbose_name=_('Education Description'), max_length=250, default=None) def __str__(self): return self.EducationInstitutionName This works perfectly and I am achieving what is needed. The issue arises when I have a table comprised of Foreign Keys which is the focal point of my application which takes the constituent parts of a CV and allows you to combine them to make a CV of interchangable sections. class Cv(models.Model): user = models.ForeignKey( CustomUser, on_delete=models.CASCADE, ) CvName = models.CharField(verbose_name=_('CvName'), max_length=100, default=None) CvEducation = models.ForeignKey(Education, on_delete=models.CASCADE) CvSkills = models.ForeignKey(Skills, on_delete=models.CASCADE) CvWorkExperience = models.ForeignKey(WorkExperience, on_delete=models.CASCADE) def __str__(self): return self.CvName This gives me... enter image description here Dropdown showing all users "Education" I've tried to filter this with init parameters but this breaks the "save" function.

Making a Django proxy for websocket (jupyter lab)
I'm having a problem with an application I'm trying to mount, I need to have a JupyterLab and notebook iframed in the django app, but I needed to proxy it through the Django app so I can use the Django authorization and authentication to access the notebooks, I used django-revproxy to proxy all the http routes to the Jupyter endpoint, and it works pretty easy, but I can't make the kernel of the Jupyter notebook to work, b/c it works through web sockets, I tried to use Django Channels and ProtocolTypeRouter/URLRouter to proxy the websockets routes, but I'm getting this error, "failed: Error during WebSocket handshake: 'Upgrade' header is missing", now I'm not sure if my approach of proxy the JupyterLab endpoints is the best, I got to a wall and I feel trap and don't know how to solve this problem, what do you recommend to handle this? thank you. -

Get user from multiple auth backend

How do I tell django to call the same method for regular views ? -

Overwrite field in queryset annotate
I have a django model with the fields name (string) and value (integer). Say I need to return a queryset of {name:..., value:...} objects, with each value doubled. What I am trying to do now is: queryset.annotate(value=F('value') * 2) However, django tells me that the field value already exists. I also tried using extra: queryset.annotate(value_double=F('value') * 2).extra(select={'value': 'value_double'}) but that also does not work since value_double is not a valid field. Of course, in this case I could use something like queryset.extra(select={'value': 'value * 2'}), but I have some other, more complicated cases involving a lot of functions where I really don't want to write sql, but I'd rather find a solution in django. Again, in all of my cases, annotate works perfectly fine as long as I give the result a new name. -

How to use the context variables passed from Django in javascript? Already changed to Json type

Model constants not available in data migrations?

Setting pre-hook for docker-compose file
I am running a dockerized django app and I am looking for a way to run (a) directive(s) every time before I build a docker container. More concretely, I would like to run docker-compose -f production.yml run --rm django python manage.py check --deploy each time before I either build or up the production.yml file. Like a pre-hook. I know I could achieve this with a bash-script, yet I was wondering if there is a way of doing this inside the docker-compose file. I can't find anything in the docker documentation (except events, but I don't understand if they serve for what I want to achieve) about it and I assume that this is not possible. Yet, maybe it is in fact possible or maybe there is a hacky workaround? Thanks in advance for any tips. -
