multiple images upload working but how to return all images related to that instance in Django rest framework
I have successfully implemented the multiple images upload , but how to return all images related to that instance in response. class ContactTransactionsViewSet(ViewSet, ListAPIView): permission_classes = [IsAuthenticated] serializer_class = ContactTransactionsSerializer filter_backends = (DjangoFilterBackend,) filter_class = ContactTransactionsFilter parser_classes = (MultiPartParser,FormParser) def get_queryset(self): user = self.request.user return ContactTransactions.objects.filter(contact__user=user, cashbook__user=user).order_by('-txn_date') def create(self, request): flag=1 data = request.data.copy() data["user"] = request.user.id if 'transaction_images' in data: images = dict((request.data).lists())['transaction_images'] else: flag=2 serializer = self.get_serializer(data=data) if not serializer.is_valid(): response_json = { "Status": "Failure", "Response": { "data": { "message": "" } }, "Error": { "code": 400, "message": "invalid request", "error_message": {} } } return Response(response_json) else: obj= serializer.save() print(obj.id) arr=[] if flag==1 and flag != 2: for img_name in images: modified_data = modify_input_for_multiple_files(obj.id, img_name) file_serializer = ContactTransactionsImagesSerializer(data=modified_data, context={"request": request}) if file_serializer.is_valid(): file_serializer.save() arr.append(file_serializer.data) else: flag = 0 if flag==0: response_json={ "Status": "Failure", "Response": { "data": { "message": "" } }, "Error": { "code": 400, "message": "invalid request", "error_message": {} } } else: dict1={"transaction_images": arr, "view_type": "body", "receive_amount": ""} dict1.update(serializer.data) response_json={ "Status": "Success", "Response": { "data": dict1 }, "Error": { "code": 201, "message": "" } } return Response(response_json) serializer.py class ContactTransactionsImagesSerializer(serializers.ModelSerializer): imagePath = serializers.SerializerMethodField() def get_imagePath(self, obj): request = self.context.get("request") return str(request.build_absolute_uri(obj.image.url)) class Meta: model = ContactTransactionsImages fields … -
get field value from form and make an object from that value django
I want to get a field value from form when submitted(object a created) and use that value to make another object(object b, which is OneToOneRelationship), if it's possible. I tried something like this, but didn't work. # models.py class Employee(models.Model): ... number = models.CharField(max_length=10, unique=True) ... class Person(models.Model): ... employee = models.OneToOneField(Employee, on_delete=models.CASCADE) ... views.py def create(request, number): if request.method == "POST": emp_form = EmployeeForm(request.POST, request.FILES) p, _ = Person.objects.get_or_create( employee=Employee.objects.get_or_create(number=emp_form.data['number'])[0] ) person_form = PersonForm(request.POST, instance=p) if emp_form.is_valid() and person_form.is_valid(): e=emp_form.save(commit=False) number=e.number e.profile = request.FILES['profile'] if 'profile' in request.FILES else None e.save() person_form.save() return redirect('employee:detail', number=number) else: emp_form = EmployeeForm() person_form = PersonForm() context = { 'emp_form': emp_form, 'person_form': person_form, } return render(request, 'employee/member_create_or_update.html', context) I know I can create Employee object first, and then add Person object later, still I'd like to know if I can create both objects in one go in one submit. Thanks for your help in advance. -

Export Django logs to Azure AppInsights with OpenCensus
I'm following this guidance for Django and Azure. I'm able to get dependancies and requests, but not traces.

Generating random string (for unique code) keeps returning the same random string
I have a Test model where each test can be identified by a unique randomly-generated string: from django.utils.crypto import get_random_string class Test(models.Model): code_length = 7 code = models.CharField(max_length=code_length, editable=False, default=generate_id(code_length)) name = models.CharField(max_length=100, default=None) user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return "Code: {} | Username: {} | Test: {}".format(self.code, self.user.username, self.name) def generate_id(length): return get_random_string(length) Tbh, it was working good before. It started to "bugged-out" after I updated my Django from Django 1.x to Django 3.x and I also cleared all the records of the Test model in django-admin (I want to have a fresh and clean database for testing). Right now, whenever I try and create a new Test, it's code is literally the same with all other new Tests that I create: I think I haven't done anything to it other than those two changes I made. Any ideas? Thanks a lot! -

Why do I get CORS error when I have the header installed in Django and React?
So I'm running both React and Django application, in port 3000 and 8000 respectively. I'm aware of the CORS policy, so installed django-cors-headers and did as written in the documentation. Like below in my settings.py: INSTALLED_APPS = [ ... 'rest_framework', 'corsheaders', ] MIDDLEWARE = [ ... 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ] CORS_ALLOWED_ORIGINS = [ "http://localhost:3000", ] I don't see anything wrong, but whenever I try to fetch the api in my React, I get error saying "Access to fetch at 'http://127.0.0.1:8000/main' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled." What do you think went wrong? Thank you very much in advance. *I've tried adding slash(/) at the end of "~~:3000", but still got the error. -
Django cannot find my base template, but it's there
I am "trying" to develop a Django project with Bootstrap. Because each page requires the exact same Bootstrap code, it looks more logical to me to have one base template at project level. Learning from this guide and this guide, here's the content of my project files: settings.py 'DIRS': [(os.path.join(BASE_DIR, 'templates')),], urls.py urlpatterns = [ path('admin/', admin.site.urls), path('', views.homepage, name='homepage'), ] views.py def homepage(request): return render(request, 'homepage/index.html') index.html {% extends 'base.html' %} {% block title %}Hello from index.html{% endblock %} {% block content %} This is from the index.html {% endblock %} Now when I browse the homepage of site (localhost:8000) I get TemplateDoesNotExist error. When I look at the error details I see this: Template-loader postmortem Django tried loading these templates, in this order: Using engine django: django.template.loaders.filesystem.Loader: D:\Django Projects\omidshojaee.com\omidshojaee_com\templates\base.html (Source does not exist) So Django is looking into the correct folder, and base.html is there (I can see it with my own eyes), so why Django cannot load it? -
python: will a custom `__module__` attribute provided to a dynamic class attrs bite me later on?
I am constructing dynamic class with type(). For some reason, when printing the class, it says something like <class 'django.forms.widgets.MyClass'>, where all besides MyClass is wrong. So I found about __module__. With this, I can make MyClass belong to the module I want it in. As far as I understand, the __module__ attribute is not really a well established standard? Found this old SO: Is "__module__" guaranteed to be defined during class creation? that explains quite well...but my question remains - are there pitfalls, or is it even considered bad practice to change __module__ of a class? Also, bonus, how come it has django.forms.widgets.MyClass as __module__ when not explicitly defining it? The real world example/proof of concept is here: https://github.com/bnzk/djangocms-baseplugins/blob/develop/djangocms_baseplugins/baseplugin/factory.py -
Execute migrations in separate postgres schema using Django
I have a requirement where my Django project needs to be connected with multiple postgres schema. For ex: If we have 20 DB tables, then 10 will remain inside public schema, then will remain in project_one schema.

How to do user authentication in django when using windows (crypt module is not supported on windows)

Django: Filter data between to dates | DatetimeField received a naive datetime
I simply want to filter my records between two dates. Let's say there is a record table Measurements that has the property timestamp: class Measurements(models.Model): id = models.BigAutoField(primary_key=True) timestamp = models.DateTimeField() When I checked the timestamp of the last record Measurements.objects.last().timestamp it returns: datetime.datetime(2020, 10, 13, 6, 29, 48, 90138, tzinfo=<UTC>) Now I want to filter the data between to dates from_date and to_date. According to previous questions about this issue, I used make_aware. For testing I used count to get the amount of entries. from .models import * from datetime import datetime from django.utils.timezone import make_aware def get_measurements(request): from_date = make_aware(datetime(2020, 10, 12, 15, 30, 0, 0)) to_date = make_aware(datetime(2020, 10, 12, 16, 0, 0, 0)) print(from_date) print(to_date) measurements = DriveMeasurements.objects.filter( plc_timestamp__range=["2020-01-01", "2020-01-31"]) print(measurements.count()) When printing the two dates in my shell, it returns: datetime.datetime(2020, 10, 12, 15, 30, tzinfo=<UTC>) datetime.datetime(2020, 10, 12, 16, 0, tzinfo=<UTC>) When I run the function above, Django fires the following message: RuntimeWarning: DateTimeField Measurements.timestamp received a naive datetime (2020-01-31 00:00:00) while time zone support is active. warnings.warn("DateTimeField %s received a naive datetime (%s)" The print statement print(measurements.count()) prints 0 but there are ~ 18000 records in the database.

Django Dashboard with Node.js
I am trying to build a Django app and currently, I wanted to program to shut down my server directly from a button and Rebooting from a separate button. html code..... <button onclick="powerOff()" class="button">Power Off</button> <p id="poweroff"></p> <button onclick="reboot()" class="Reboot">Reboot</button> <p id="reboot"></p> Javascript code:... <script> function powerOff() { if (confirm("Are you sure you want to power off ?")) { require('child_process').exec('sudo shutdown -r now', function (msg) { console.log(msg) }); } } function reboot() { if (confirm("Are you sure you want to reboot ?")) { } else { } </script> When I am running this code directly from my terminal it is functioning but it is not executing from the app.
