DRF and React Login, JWT authentication header missing in request
I'm currently making a Login System in a Django/React and the SimpleJWT RestFramework and so far everything related to JWT and protected (API)Views, works except in the Django Frontend. The Login Frontend is in React, which posts the login credentials and gets the JWT-Token from the api and saves them to localstorage and sets it as header for axios: const handleSubmit = (e) => { e.preventDefault(); axiosInstance .post(`token/`, { email: formData.email, password: formData.password, }) .then((res) => { localStorage.setItem('access_token', res.data.access); localStorage.setItem('refresh_token', res.data.refresh); axiosInstance.defaults.headers['Authorization'] = 'JWT ' + localStorage.getItem('access_token'); history.push(""); location.reload(); }).catch(err => console.log(err)); }; api urls.py: path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), Every API call i make with axios works and only returns after logging in... as it should be... BUT the problem is in the second Frontend, which is in Django. It is a partly static frontend that consists mainly out of simple html-templates for the Homepage, but with a Navbar which requires User information. @api_view(['GET']) def home(request): print(request.header) context = { 'posts': posts } return render(request, 'SmartGM_MainApp/home.html', context) I noticed that the Authentication Header are simply missing: When i try to print the user-data after logging in : request.user, output is AnonymousUser After making the template view protected by … -

DRF Create object with nested object parameters
I have this two classes in my Django Rest Framework project class Call(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4) client = models.ForeignKey('client.Client', on_delete=models.CASCADE, db_column='id_client') class Client(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4) name = models.CharField(max_length=250, unique=True) Then I have my view that simply extend "CreateApiView" without any additional code and then the serializer: class CallSerializer(serializers.ModelSerializer): client = ClientSerializer() What I simply need to do is to create a Call object after a POST, sending as parameters my client object. The problem is that if I do so, django returns me this error: A client with that name already exists. So I tried to edit the serializer this way ClientSerializer(read_only=True) but this time it creates the Call object with Client set to null. How can I fix this? I know I can simply remove the nested ClientSerializer and then send the ID instead of the whole Client object, but is there a way to do it with the nested serializer? -

How to only create .pot files with django manage.py makemessages
Weblate has an add-on called "Update PO files to match POT (msgmerge)". I want to delegate the creation of .po files to Weblate and only use manage.py makemessages to create the .pot file(s). manage.py makemessages has a --keep-pot option, which adds .pot files to the output. Unfortunately there is no option to only keep the .pot files. -

Django - how to retrieve object by foreign key only?
I have a model PredictorSetterItem, which has a foreign key pointing to PredictorSetter model: class PredictorSetterItem(models.Model): predictor_setter = models.ForeignKey(PredictorSetter, null=False, on_delete=CASCADE, related_name="predictors") When PredictorSetterItem is created, it's assigned a PredictorSetter model in the following way: pdi = PredictorSetterItem() pdi.predictor_setter = predictor_setter so, as I understand, predictor_setter inside PredictorSetterItem, while being a ForeignKey, points to one and only one PredictorSetter object, so one PredictorSetter can be pointed by multiple PredictorSetterItems, but each PredictorSetterItem has one and only one associated PredictorSetter. My question is - how do I retrieve PredictorSetter object back? I can't directly get it's attributes via predictor_setter.attribute statements from inside PredictorSetterItem object. So I need to formulate a QuerySet and get the model, but I have no idea how to do that. I don't know primary key or any another attribute of PredictorSetter to filter, but this should be unnecessary, since PredictorSetterItem is associated with one and only one PredictorSetter object. -
Django annotate with model values
The Django docs on aggregation give the following example for annotations: for store in Store.objects.all(): store.min_price # Error! min_price not defined! for store in Store.objects.annotate(min_price=Min('books__price')): store.min_price # Fine However, we only annotated a single field. We only know what the price of the cheapest book is, but not exactly which is the cheapest book. What if I wanted the result of the annotation be precisely that book, not just its price? (I'll call this function or class AggregateRelation) for store in Store.objects.annotate( cheapest_book=AggregateRelation('books__price', Min) ): store.cheapest_book.price store.cheapest_book.title Is there a way to do this? I checked up FilteredRelation but that's only useful for filtering. It does not truly retrieve the instances. -

Django Keeping the same filter in pagination
I looked into the previous questions about this but did not find exactly the answer to my problem as I am not using django-filters. I am applying filters to a Search Page and I am using pagination. Of course when you move to the next page all filters are reset. I want to be able to include the same filters when we move from page to page.

Django 1.4: Tests are very slow
I am working on a old code base which still uses Django 1.4 This means the nice flag --keepdb is not available. Running a single test like this takes 50 seconds: time manage.py test myapp.tests.test_foo.FooTestCase.test_something My test_something method is fast. It is the creation of the test-DB which takes so long. 50 seconds is too long for a productive edit-test-cycle. What can I do (except faster hardware)? -

Here's the code: View I want to turn into pdf class CalculationDetailView(UserPassesTestMixin, LoginRequiredMixin, generic.DetailView): model = Calculation def test_func(self): return self.request.user.is_authenticated def get_queryset(self): qs = super().get_queryset() if not self.request.user.is_staff: qs = qs.filter(userid=self.request.user.pk) return qs View that generates pdf set up by following django-puppeteer-pdf docs class GenerateCalcDetailPdf(PDFTemplateView): filename = 'details.pdf' template_name = 'cycle\calculation_detail.html' header_template = 'base_generic.html' cmd_options = { 'margin-top': 3, } urls.py url(r'generate-pdf/$', views.GenerateCalcDetailPdf.as_view(), name='generate-pdf') The template content is dynamically rendered from the database and styled with Bootstrap. It contains static files and here are the static settings: PROJECT_ROOT = os.path.abspath(os.path.join(os.path.dirname(__file__), '..')) sys.path.append(os.path.join(PROJECT_ROOT, 'orc2')) STATIC_ROOT = os.path.join(BASE_DIR, '/static/') STATIC_URL = 'static/static/' # Extra places for collectstatic to find static files. STATICFILES_DIRS = [ os.path.join(PROJECT_ROOT, 'static'), ] Any advice or help is welcome since, according to docs I'm doing everything properly but for some reason it doesn't work properly. -

I'm trying to practice ajax in django but I got this error 'QuerySet' object has no attribute 'META'. But it's showing the data in the traceback but not in the template because of the error.How to fix this? models.py from django.db import models # Create your models here. class Profile(models.Model): name = models.CharField(max_length=100) email = models.CharField(max_length=100) bio = models.CharField(max_length=100) def __str__(self): return self.name I think it has something to do with the views but I cant figure it out. views.py from django.shortcuts import render from .models import Profile from django.http import JsonResponse # Create your views here. def list(request): return render(request, 'livedata/list.html') def getProfiles(request): profiles = Profile.objects.all() # print(JsonResponse({"profiles": list(profiles.values())})) return JsonResponse({"profiles": list(profiles.values())}) urls.py from django.urls import path from . import views urlpatterns = [ path('', views.list, name='list'), path('getProfiles', views.getProfiles, name='getProfiles') ] index.html {% load static %} <!doctype html> <html lang="en"> <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous"> {% comment %} <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> {% endcomment %} <script src="https://code.jquery.com/jquery-3.5.1.js" integrity="sha256-QWo7LDvxbWT2tbbQ97B53yJnYU3WhH/C8ycbRAkjPDc=" crossorigin="anonymous"></script> <script src="{% static 'js/main.js' %}" defer></script> <title>Hello, world!</title> </head> <body> {% block contents %}{% endblock contents %} {% block scripts %}{% endblock scripts %} <!-- … -
How to display error message with Django forms?
I would like to customize the Django login authentication form. The original form looks like this and it works perfectly: {% extends "blog/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4 ">Log In</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Login</button> </div> </form> <div class="border-top pt-3"> <small class="text-muted"> Need An Account? <a class="ml-2" href="{% url 'register' %}">Sign Up Now</a> </small> </div> </div> {% endblock content %} My goal is to modify the form style so that I can place the objects wherever I want. I was able to achieve this for the username and password fields, however I cannot display the error message just like in the original format. This is what I tried: {% extends "blog/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4 ">Log In</legend> {% if formset.non_form_errors %} <div class="alert alert-block alert-danger"> {% if formset_error_title %}<h4 class="alert-heading">{{ formset_error_title }}</h4>{% endif %} <ul class="m-0"> {{ formset.non_form_errors|unordered_list }} </ul> </div> {% endif %} <div class="row"> <div class="col-md-4 col-sm-12 register-field"> {{ form.username|as_crispy_field }} </div> <div class="col-sm-12 register-field"> {{ form.password|as_crispy_field }} </div> </div> … -
Djagno start server, scan Network and write data to DB
My idea Store network devices data threw a Django Model (Device Model) to my Database. Host configuration needs to be setup by User inside a View (Host Model) When the Host configuration is finished the Network should be scanned for devices (Device Model) The Data should be stored inside the DB The fuction create_devices() gets called before a host was setup, with migrate and makemigrations.
