Assign value to logged in user in Django
I have a Django app where I am trying to assign a bank variable to each user, set to 100 by default. I have the following model in models.py : class Wallet(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bank = models.FloatField(default=100) which is then used in views.py: class BitgainzView(View): def get(self, *args, **kwargs): user = User.objects.get(username=self.request.user) context = {'bank': user.wallet.bank} return render(self.request, "index.html", context) I then print bank in my html page. Two problems with this : if user is logged in : I get the error Exception Value: User has no wallet. which I think is because the schema for Wallet was created in relation to User, but never initialised for each user. if user is not logged in : Then the context in BitgainzView() cannot be loaded, and I am also getting an error. Should I make separate views in that case ? Or should I treat different cases inside this function ? Thank you in advance. -

Concept for secured app login: someone here has a better idea, something to add that we have overlooked?
Our Situation: we are in the process of developing a concept for a login screen, for a palette of different online apps. all online apps should be available via the same login, depending on the associated user group. available online apps should be listed after login. except for the security service, all apps are independent of each other, they can be hosted on separate servers, etc. the online applications are React apps (based on TypeScript). the backend runs with Django (based on Python). (the backend framework is fixed for specific technical reasons and will be django, we need no suggestions for a different backend framework) now we are looking for the best prectise and sefest method to prevent insights and attacks as much as possible. Our Conecpt: our idear for this is, to build the login apllication with react native, to render the frontend on server site. so, the maximum visible communication tranfair with the server, will be the user credentials to the server. Login Form (React Native): Login screen as standalone app for all restricted apps Server site website rendering Server site authentication (no API call) Login credentials: "username" and "password" List available apps after sucessfull authentication Redirect with … -

Django DRF - Access to field ForeignKey instance inside a custom serializer validator method
I'm currently having a bit of a conceptual headache over how best to reference the instance of a ForeignKey field inside a custom serializer validator method ... To give an overview of the system. I have the following "Candidate" model, the imporant fields for this question are the user, job* and status fields. from model_utils.fields import MonitorField, StatusField from model_utils import Choices class Candidate(models.Model): class Meta: ... STATUS = Choices( 'matched', 'approached', 'invite_rejected', 'invite_accepted', 'reviewed', 'interview_scheduled', 'hired', 'rejected' ) user = models.ForeignKey('users.User', on_delete=models.CASCADE) job = models.ForeignKey('jobs.Job', related_name='candidates', on_delete=models.CASCADE) ... status = StatusField(default='matched') ... def save(self, *args, **kwargs): super(Candidate, self).save(*args, **kwargs) The status field for the Candidate can only be "updated" to a given value based on who they are, and what they're attempting to update the status to. Effectively, my outlined logic is as follows inside the serializer: from rest_framework import serializers from .candidates.models import Candidate class CandidateSerializer(serializers.ModelSerializer): class Meta: model = Candidate fields = '__all__' def validate_status(self, value): user = self.context['request'].user if user.is_anonymous: raise serializers.ValidationError("The requester must be logged in to make a change to the status field") # Ensure status value is in valid list of statuses if value not in [ 'matched', 'approached', 'invite_rejected', 'invite_accepted', 'reviewed', 'interview_scheduled', … -

In Django, how to display time which updates every minute?
Using tag {% now %}, I can display the time, but the time is static and doesn't update every minute. Is there anyway to update this time? Is it possible to do this with javascript's setInterval and django's {% now %}? Tried this: <script> setInterval(function () { $("#current_time").text("{% now "jS F Y H: i " %}"); }, 60 * 1000); // 60 * 1000 milsec </script> But this doesnt work as django renders now value only once(when page loads) and it remains same all time -

How to add list of unique models to a django model
I am developing a dashboard app for clients to manage their devices with django and mariadb database. I have a Client model (which is the extended user model) and Device model which represents single, unique device. One user can have multiple devices, but one device can be assigned to only one user. Now, what is the best way to create an entry in Client model, that will contain all his assigned devices. What is important, one device (represented by unique device id) can appear only once in all Client.devices tables. Here is the code to visualize my problem: class Client(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) devices = <?> class Device(models.Model): type = models.PositiveSmallIntegerField(default=0x00) id = models.PositiveSmallIntegerField(primary_key=True, default=0x00) user = models.ForeignKey(User, unique=False, on_delete=models.CASCADE) I feel like the answer is out there, but I'm not sure that other similar topics would match my uniqueness -
Django Q filter, cant get results in a single query
I want to make a query with multiple conditions to get some objects out of my Order model, but i can't find a way to get all the results in a single query. Besides the option to make 2 queries, i would like to know if this is possible with just one so i can create a CSV sheet with all of these orders(this part already works so i will stick to the query). The conditions: paymethod: Paypal and Mollie created_at: in hours 15:00 and 16:00 & paymethod: ApplePay created_at: in hours 17:00 and 18:00 The two queries: Order.objects.all() \ .filter(Q(paymethod="Paypal") | Q(paymethod="Mollie") & Q(created_at__hour__in=(15, 16))) Order.objects.all() \ .filter(Q(paymethod="ApplePay") Q(created_at__hour__in=(17, 18))) These two queries work fine seperatly, but i would like to know if it is possible to combine them to a single query. i have tried something like: Order.objects.all() \ .filter(Q(paymethod="Paypal" | "Mollie", created_at__hour__in=(15, 16)) \ & Q(paymethod="ApplePay", created_at__hour__in=(17, 18))) The above does not work because of: TypeError: unsupported operand type(s) for |: 'str' and 'str'.

Would really appreciate if someone can point me into the right direction. I'm still learning django … -

How to create an approval system for a model in Django?

Reliable File transfer from Django to external FTP
I have a Django application that needs to upload files generated upon the update of a model objects. More concretely, once a database entry is modified, a function has to be fired to generate a tiny CSV file and upload it to an (S)FTP server. My question is on how to make the uploads reliable and performant (possibly couple of thousands transactions a day). That is, make sure the files are always uploaded with possibly few duplicates without overloading the Django instance. One option I explored was to send these tiny CSV files to a cloud queue (e.g. AWS SNS/SQS) and have another CRON job (e.g. AWS Lambda) to fetch the queue and upload the files. Any ideias for the architecture?
