Django model auto update status when the medicine is expired
How to Auto update the status when the medicine is expired? for example, I created medicine record and set the expirationdate to july 2022, if the current date is greater than the expirationdate it will update the status of medicine to "Expired", How do I do that? class Medicine(models.Model): medstatus = [ ("Expired", "Expired"), ("Active", "Active") ] description = models.CharField(max_length=50, null=True) expirationDate = models.DateField(null=True) status = models.CharField(max_length=50, choices=medstatus, null=True) -
I change the error message, but it doesn't change
I change the error message in the model, but it doesn't change. I can't understand why this approach doesn't work, because it works for other fields it's my model class CustomUser(AbstractUser): username = models.CharField( max_length=15, unique=True, validators=[UnicodeUsernameValidator()], error_messages={ "unique": "Test login", }) group = models.OneToOneField('Group', unique=True, on_delete=models.CASCADE, error_messages={ "unique": "Test group" }) email = models.EmailField(models.EmailField.description, unique=True, validators=[email_validator], error_messages={ "unique": "Test email", }) def __str__(self): return self.username and it's my Group Model class Group(models.Model): name = models.CharField(max_length=20, unique=True) faculty = models.ForeignKey(Faculty, on_delete=models.CASCADE) def __str__(self): return self.name When testing in postman, I get this: { "username": [ "Test login" ], "group": [ "This field must be unique." ], "email": [ "Test email" ] } Thank you in advance -
Create User in django using Rest Framework
i've seen people using different ways to create user in django Rest framework. i tried & none of them is working for me. sometimes it says Key error: Groups or something else. so i tried this without having a is_valid & it works like a charm. is this a safe way to use to create user or if not why & how should i create User in views? #my views.py @api_view(['GET','POST']) def getUserData(request): if request.method == 'POST': user = User.objects.create_user( username=request.data['username'], password=request.data['password']) serializer = userSerializer(user) return Response(serializer.data) -

Why my images are missing when deploying django and postgresql on heroku?
I create a webapp with Django for the backend and React for the frontend. I deploy the app on heroku and I use the heroku-postgres as the database, after deployin the app everything works perfectly (superuser, models.py etc...). Now I connect to the superuser account and try to add data, all data is displayed on the application frontend except the images. Note that I have a static folder and also I have run python manage.py collectstatic before deploying the app on Heroku. What can I do to make the images displayed every time I add them? -

I've installed Django any mail and am I trying to use mail gun with it for password resets. I've added any mail to my installed apps and tried to use mail gun as an API or smtp service.

Django elastic beantstalk createsuperuser issues
I have a django project which I have managed to deploy to elastic beanstalk server but have spent the last two days trying to create super user but to no avail. I have followed different guides and answers from this site but for the life of me I just cannot get this working.

django-tenants global device table mapping to tenants
We are using django-tenants to provide a multi tenant solution for an iot platform and I'm having an issue figuring out how to map some global data to tenant specific tables. Basically we have iot devices that talk to a node.js server using a proprietary protocol over tcp, that server then makes rest api requests to a Django webserver to update the database with device measurements. The node server does not know anything about which device belongs to which customer so it needs to have a rest api that is global and then the webserver backend will need to map that device to a specific tenant but we cannot let tenants view each other's data so I'm not sure how we accomplish this as it seems apis are either tenant specific or global (public). -

django rest framework Viewset for single item, not list
I am having a problem with my DRF API. I want to provide a read only endpoint that takes a single id from a object(document) in the DB and runs a script to perform an check and gives back the result. It works fine when I call the API with //api/documentcheck/1/ where 1 is the pk of the document in the DB. The problem is that if I just call the base URL //api/documentcheck/ it tries to give back the results of all documents in the database and times out because it takes ages. I am looking for a way to remove the list view and force users to provide the ID for a single document to check. This is my serializer class class DocumentCheckSerializer(serializers.Serializer): '''Serializer for document check''' class Meta: model = Document fields = '__all__' def to_representation(self, value): return process_document(value) This is my view: class DocumentCheck(viewsets.ReadOnlyModelViewSet): """Check a single document""" authentication_classes = ( TokenAuthentication, SessionAuthentication, BasicAuthentication, ) permission_classes = [IsAuthenticated] queryset = Document.objects.all() serializer_class = serializers.DocumentCheckSerializer and my router entry router.register("documentcheck", views.DocumentCheck, basename="documentcheck") -
I'm tyring to make an API following instructions on CodewithMosh
I'm learning python on a website called codewithmosh. I'm at the point where I'm doing a project with Django but every time I try to run my server (“python3 manage.py runserver”) to launch the site with a new API I made, It gives me this error message: "ImportError: cannot import name ‘_sanitize_token’ from ‘django.middleware.csrf’ (/Users/alecsmith/.local/share/virtualenvs/vidly-mJrVeZC4/lib/python3.10/site-packages/django/middleware/csrf.py)" I guess you would have to see my whole folder to understand what the issue could be, but if someone could give me some basic advance that would be appreciated. I re-followed the instruction 3 times and I still get that message. -
which pip package creates psycopg2 dependency?
This is what i mean, i am trying to install all the packages in my requirements.txt (django/python), i did not specify some packages like asgiref, psycopg2, urllib etc, but it just starts downloading or installing them too, then i thought: there must be some packages that are also downloading these other asgiref, psycopg2, urllib etc as dependencies.

Make Django admin object page show less?
I am currently trying to have the item page in the django admin (ie, /admin/dictionary/word/153/change) show less, I am just unsure how to do this.

Python function to get sytem mac address
I am developing an API using Django rest framework. I need a user's mac address to be in the list of an organization's mac addresses before he is authorized to access the organization's data. But the challenge is that this code returns different mac addresses when the code is hosted and when I am running it on my local machine. I don't know what I am getting wrong. and I really don't know much about networks too.

Django assigning model FloatField coordinate points to marker coordinates using Mapbox
For my project I have a model that had two FloatFields called lat and lng for coordinate value which I would like to display on an interactive map. Just starting with Django and API's so still very new to a lot of this. animal = models.CharField(max_length=32, choices=ANIMALS, default=BISON) image = models.ImageField(upload_to='images', null=True, blank=True) description = models.TextField(null=True, blank=True) lat = models.FloatField(blank=True, null=True) lng = models.FloatField(blank=True, null=True) def __str__(self): return self.animal I am not sure how to access these values from my views page so that I am able to use them as {{ Django variables }} within my html template.

Django isn't authenticating user already logged in through web app frontend using keycloak
I am building an application that uses django as a backend for data processing and management calls served to a Vue3 SPA. I am using Keycloak for authentication and using keycloak-js and mozilla-django-oidc to handle authentication for each. Each work separately fine, I can navigate to the django app, login and see the data behind protected views (and get redirected properly if I a not logged in). Likewise I can login to the frontend and get a token and associated data. I can even login to the django app, then navigate to the frontend and calls are made with the correct session information and it all works fine. The challenge is when I just login to the frontend and make a call to the django app it doesn't recognize it as being an authenticated user request - I am guessing it has something to do with not creating a django session, but am honestly a bit lost at this point. Is there a way to ingest the token information and have django authenticate the user and start a session when the call is made from the frontend? -
How to use react-image-crop with python-django backend cropping?

Query parameter doesn't match any record returns "Select a valid choice. That choice is not one of the available choices." instead of empty array
I'm using DjangoFilterBackend to handle query parameters on a ModelViewSet. My expectation would be that if nothing in the table matches one of the query params, that it would just return an empty array. Instead it returns: { "document_guid": [ "Select a valid choice. That choice is not one of the available choices." ] } Which just seems like an odd response to me so I'm wondering: how can I change this behavior? Would much rather just have the following indicating nothing matched: [] I'm aware of this similar question, but I'm already doing what they suggested: https://stackoverflow.com/a/62219220/3123109 Here's the URI where there are no records that match document_guid (but there are some that match user_guid): localhost/api/d2u/?user_guid=55d57235-79b0-ec11-9840-000d3a5a343c&document_guid=df4c9c11-49dd-ec11-a7b6-000d3a3667a1 Here's the related code: # views.py class Document2UserSyncViewSet(viewsets.ModelViewSet): filter_backends = [DjangoFilterBackend] filter_fields = [ 'id', 'document_guid', 'user_guid' ] permission_classes = [PowerAutomatePermissions] queryset = Document2User.objects.all().order_by('id') serializer_class = Document2UserSerializer # serializer.py class Document2UserSerializer(serializers.ModelSerializer): """Serializer for the d2u model.

Can't find the Django Docs that list DetailView attributes
Working through the Django tutorial and on the Detail and List class-based views portion. When I go to the docs for the DetailView, it doesn't really list any of the attributes I can use or the tutorial uses. Any chance someone has a link to the page where I can read up on attributes like: -Model -Context_object_name -template_name -etc... I just like to understand what Im doing a bit more than the tutorial explains, just cant seem to find the proper docs when googling :(
