Django simplejwt: How to add refresh token to dict?
I am using simplejwt to get an access and refresh tokens. In a view I need to create a dict, where the both will be stored as well as access token claims and another additional data. Everything works but by some reason when the refrsh token is added to dict, it returns its decoded value, but not the token. my views.py @csrf_exempt #@api_view(('GET',)) def check_token(request): token_refresh = RefreshToken.for_user(request.user) print('REFRESH', token_refresh) token = request.META.get('HTTP_AUTHORIZATION', " ").split(' ')[1] data = {'token': token, 'refresh_token': token_refresh} try: valid_data = TokenBackend(algorithm='HS256').decode(token, verify=False) data['uui'] = valid_data['user_id'] data['validUntil'] = valid_data['exp'] data['clientId'] = 'default' print(data) return JsonResponse(data) except ValidationError as v: print("Validation error", v) print('REFRESH', token_refresh) returns the token: 'REFRESH eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI...' but data object returns: {'token': 'eyJ0eXAiOiJKV1QiLCJhbGci...', 'refresh_token': {'token_type': 'refresh', 'exp': 1628664751, 'jti': '38f0e3a4d7bb452681834a6b149aa496', 'user_id': 'None'}, 'uui': 1, 'validUntil': 1628059131, 'clientId': 'default'} my ideal result: {'token': 'eyJ0eXAiOiJKV1QiLCJhbGci...', 'refresh_token': 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI...', 'uui': 1, 'validUntil': 1628059131, 'clientId': 'default'} -
Can I use the same @property on multiple models in django?
I want to define an @property once and use it on two different models. Is this possible? Example: Suppose I have two models, seller and buyer: class seller(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) class buyer(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) And I wish to add a property for the django admin interface to display both models: @property def display_name(self): return f"{first_name} {last_name}" Is there a way to define this property once, but use it for both models? -
Use Django ORM in multiprocess spawn process
i need to use the Django ORM in some spawned process using python multiprocess module. At this moment, this how i spawn the process: import multiprocessing with multiprocessing.get_context('spawn').Pool() as pool: pool.map(insert_to_db, args) Now, here is the issue: the function insert_to_db uses the django ORM to get some objects, check data consistency and save the new collected result to DB. Actually, i can't start the spawned process using fork context due to some unidentified deadlocks. My initial idea is to start a the process, inject the Django dependencies, and before doing the execution of the insert_to_db function execute the django.setup() to load all django things. Anyone is able to give me a solution? -

How to configure django standalone app to install automatically all sub apps?
Problem description I have django standalone app named django_codeserver. It can be loaded from my private package registry as a pip-package. My app contains about twenty sub-apps for example django_codeserver.headers, django_codeserver.genders etc. Current behaviour To register all models in my project which uses django_codeserver, I have to register all the sub applications in the parent project INSTALLED_APPS such as: INSTALLED_APPS = [ ...

Django CheckConstraint With IntegrityError
I have a constraint that I'd like to add in my Django Model. I thought the CheckConstraint method would help to catch the error when the input does not meet the constraint. However, when I saved the model with an invalid input, e.g. percentage = 101, an error page was shown with IntegrityError. Does anyone here know how to properly use this method to validate the input? class Meta: constraints = [ models.CheckConstraint( check=Q(percentage__gte=1) & Q(percentage__lte=100), name="Please enter a valid percentage", ) ] -
django select_related().values() not returning all fields from 2 tables
I have 2 tables, one child (Car) and the other parent (Dealership). I'm using the orm query Car.objects.all().select_related('dealership').values() to perform a left join which would give me all the fields from both cars and their related dealerships but that's not happening as I'm only able to get all the fields from the Car model. class Dealership(models.Model): ... class Car(models.Model): dealership = models.ForeignKey(Dealership, on_delete=models.CASCADE, null=True, default=None) ... I read it in a different question that with .values() I'll have to explicitly mention all the required fields but there are just too many fields to enter manually. Is there a cleaner solution to this? -
How to redirect user to the desired page after login using LoginRequiredMixin in django?
I have created a mini project called ToDoList App. I have used class based views for create, update and delete functions. There is MyTasks icon on navbar. What I want? If the user is not logged in and he clicks on MyTasks icon, he should be redirected to the login page and after login to MyTasks page. I have used LOGIN_REDIRECT_URL = 'home' and LOGIN_URL='login' in settings.py file If I write LOGIN_REDIRECT_URL = 'task_list', it is working fine else not. Below is the code from views.py file: class TaskListView(LoginRequiredMixin, ListView): """List of all tasks.""" model = MyTasks context_object_name = 'tasks' template_name = 'task_list.html' This is from urls.py file: path('tasks/', views.TaskListView.as_view(), name="task_list"), I have used the attribute redirect_field_name='next' and tried to override dispatch method in the above class, still it is not working. The output I am getting is, after login, it is getting redirected to homepage instead of my tasks page. Any help is much appreciated.

Make a form that pulls choices from table in DB and then allows user to change to different foreign keys

Django Form is Not Visible - Using Model Forms
I'm trying to create a form on my site but the form itself is not visible. I just have a button to 'create post' but the form itself doesn't appear. I've been reading the Django documentation and so far haven't found an answer. I also tried making sure GET requests are explicitly mentioned in my views.py because I saw a post on this site, saying that can sometimes cause this. I'm also using form.as_p in my html file.

Using django-autocomplete-light and django-addanother for the same field in a ModelForm
I'm trying to implement django-autocomplete-light and django-addanother for the same field in a ModelForm. I've tried the following: import floppyforms.__future__ as forms from .models import Worker from dal import autocomplete from organizations.models import Hub from django.urls import reverse_lazy from django_addanother.widgets import AddAnotherWidgetWrapper from django.forms import MultiWidget class WorkerCreateForm(forms.ModelForm): class Meta: model = Worker fields = ['display_name', 'hub', 'capacity', 'vehicle', ] widgets = { 'hub': autocomplete.ModelSelect2(url='hubs-autocomplete', attrs{'data-html': True}), 'hub': AddAnotherWidgetWrapper( forms.Select, reverse_lazy('create_hub')) } This will only render the AddAnotherWidgetWrapper obviously. I've tried to use MultiWidget in multiple ways and every time I got a different error (I will not post all my trials and errors since most of them don't make a lot of sense, but if you think I should share them I would be happy to do so). I'm finding it hard to understand how to use MultiWidget since there are no clear examples, and I'm not sure if it's the right solution for my use case. In django-autocomplete-light's documentation, they recommend using django-addanother for adding a model with multiple fields, but there's no explanation on how to implement it. I'd like to know if there's an easy way to use both packages together or if I should write … -
