In DJANGO, Is there a way to transfer the existing users in django.contrib.auth to SAML or OpenID?
I have used django-oidc-provider, but all it does is create a new user. For a large pre-existing user datatbase, it is inconvenient to create new accounts for all users. I want to do this because I cannot integrate AWS services into my django website without an industry standard for federated authentication. -
Using Swup with Django
My Issue: I am trying to use Swup Library with Django's templating engine and everything worked well; except for the fetching of new content. The animations worked perfectly; I could see my contents getting faded out. The addresses in which the get requests are fetching worked perfectly as well; I could see the HTTP response code of 200 being returned in my console. However, the main content, after being faded out, were not being replaced. An example of Django Renderings: Base URL: http://127.0.0.1:8000 <!-- What is written in my code --> <a href="{% url 'home_view' %}" > <!-- What Django renders in the browser --> <a href="/" > in my urls.py: urlpatterns = [ path('', views.homeView, name='home_view'), ] A worthy note: Using dev tools, when hovering over the href rendered, it shows http://127.0.0.1:8000/ Another strange thing I encountered when trying to debug was that my html element has the following attributes added to it but it stay there even after the animation ends. <html lang="en" class="swup-enabled is-changing is-leaving is-animating to-homepage"> Swup config or any additional relevant code used: let options = { LINK_SELECTOR: 'a', debugMode: true, }; const swup = new Swup(options); The Scripts loaded perfectly; I was able to … -
Adding Additional Data to a Serialize Response in Django
I've created a working post response of data from the model using ModelSerialzer, which I call from a post method in a view class. I would like to add additional data to the response. This is the pertinent code from my CBV: resource_data = Resources.objects.all() serializer = ResourceSerializer(resource_data, many=True) #serializer.data["service"] = "All Services" return Response(serializer.data) The commented out line was my attempt to add data base on a similar post here. I get a 500 response in my API call. What is the correct way to do it? The response data is JSON if that's necessary to mention. -
integrating ebay authentication in django application
I am building a django application in which user will be able to sign up or sign in only via their EBay account, no email/username or password required. I couldn't find any authentication library for EBay though there are many for google, facebook, twitter etc. So I got the EBay part working. EBay basically returns (on consent of user) Email and a IEFS token which is unique to that user and wont change. I want to use those two fields only to create a authenticate user across whole application. I don't want username, emails, firstname, lastname or password that ships with django User model. The documentation is quite big and I am confused where to start, any proper suggestion will be big help. Thank you. -
Django POST request not posting anything to database
I cloned Django free source code on GitHub and making modifications to it. The aim of my application is that I wrote an ML algorithm that predicts if one is to have diabetes or not. Here is my issue, the person made use of a single function that calls multiples pages through the help of Django loader. Now hitting on the submit button I want that function to run a submit based on the current page I am on. The function is shown below @login_required(login_url="/login/") def pages(request): context = {} # All resource paths end in .html. # Pick out the html file name from the url. And load that template. try: load_template = request.path.split('/')[-1] print(load_template) context['segment'] = load_template if request.method == "POST": print("YES") print(request.POST) person = Person(request.POST) print(person) person.name = request.POST.get("name") person.email = request.POST.get("mail") print(person.email) person.dob = request.POST.get("dob") person.gender = request.POST.get("gender") person.pregnancy = request.POST.get("Pregnancies") person.glucose = request.POST.get("Glucose") person.blood_pressure = request.POST.get("BloodPressure") person.skin_thickness = request.POST.get("SkinThickness") person.insulin = request.POST.get("Insulin") person.bmi = request.POST.get("BMI") person.pedigree = request.POST.get("DiabetesPedigreeFunction") person.age = request.POST.get("Age") print(person.save()) ml_pickled_model = "django-datta-able-master/ml/dataset/ml model.pkl" person_data = np.array( [ [ person.pregnancy , person.glucose , person.blood_pressure, person.skin_thickness , person.insulin , person.bmi, person.pedigree , person.age ] ] ).reshape(1,8) test_model = joblib.load(open(ml_pickled_model, 'rb')) prediction = test_model.predict(person_data) print(prediction) … -

I tried to remove the default admin user on cyberpanel as follows: Create a new user with the highest authority admin Login cyberpnael with new user and go to user section to delete admin user.

I need to translate, or change "Please fill out this field" error message in UserCreationForm on Django
I have been trying and investigating a lot how to change just the error message, or just translate it to Spanish, but I do not manage to find quite the solution. I have tried using locale.Middleware on settings and adding the gettext to my Django project in order to translate it, no luck, here are the settings I am using: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] gettext = lambda x: x LANGUAGE_CODE = 'es' LANGUAGES = ( ('es', gettext('Spanish')), ) TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True After having those settings, and installing the gettext accordingly on my locale folder, no luck in translating the error messages. I have also tried on the forms.py changing the error_messages, but no luck, here is the code for the forms.py file (I have added 'required' everywhere just to see if the message slightly changes, no luck either, also I used 'required' and 'blank' neither worked): class CreateUserForm(UserCreationForm): first_name = forms.CharField(error_messages = {'required':"Ingrese su primer nombre"}, max_length=30,widget=forms.TextInput(attrs={'placeholder': 'Ingrese su nombre', 'class': "form-control"})) last_name = forms.CharField(error_messages = {'required':"Ingrese su segundo nombre"},max_length=30,widget=forms.TextInput(attrs={'placeholder': 'Ingrese su apellido', 'class': "form-control"})) password1 = forms.CharField( label="Password", error_messages = {'required':"Ingrese la … -
Django Get All Cookies With Name That Includes A Substring
I am making this simple random post system, and a problem I've been having is to recommend posts a user has not seen before. To differentiate a use who has seen a post and who has not seen a post, I store a cookie (for anonymous viewers) like so: def render_to_response(self, context, **response_kwargs): # Logic response.set_cookie(f'viewed{post_id}', 'true', max_age=60*60*24*10) # 30 Days Till Expiry This stores a cookie like if I have a post with id=12, it will be stored as: viewed12, true To get the value I do: request.COOKIES.get(f'viewed{post_id}') I want to know retrieve all cookies that begin with the string viewed and then I want to get everything after that (so I just want to get the id of the post from the cookie). This is my code: import random def random_post(request): objects_to_exclude = [1, 2, 8] # Using the cookies with substring "viewed" I want to insert into this list posts = Post.objects.all().exclude(pk__in=objects_to_exclude) post = random.choice(posts) return render(request, 'blog/post_detail.html', {'object': post, 'post': post, 'id': post.id, 'pk': post.id, 'random': 'True'}) Basically I want to find all the cookies with substring viewed, get the number after it, and then insert it into the list called objects_to_exclude.

Rendering data to the templates Django
I'm trying to display the data from table using dynamic url. However, when I try to do so, it just rendered out the attribute of the table instead. But when I use the same syntax to print on the shell, it works here is my view def service_fait(request, my_id): if request.user.is_authenticated: elements = JobServices.objects.filter(id=my_id) for element in elements: print(element.service_name) print(element.hour) print(element.user) print(element.description) return render(request, 'services_faits.html', {'elements': elements}) else: return redirect('login') Here is the dynamic url: path('servicefait/<str:my_id>', views.service_fait, name='servicefait') And the template is: {% for tache in taches %}<a href="{% url 'servicefait' tache.id %}" class="btn btn-primary">Postuler</a>{% endfor %} Here is the output of the web page: element.service_name element.hour element.amount element.description And the shell is working properly as it shows the content of the above attribute And finally, here is the model: class JobServices(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) service_name = models.CharField(max_length=100, default="nom du service") hour = models.IntegerField(default="Heures") amount = models.FloatField(default="Cout") service_date = models.DateTimeField(auto_now_add=True, null=True) description = models.CharField(max_length=2000, null=True, default="annonce") image_url = models.CharField(max_length=2000, null=True, blank=True) image = models.ImageField(null=True, blank=True) -
Optional Subfactory
I would like to create a subfactory that only creates instances if the user requests it at call time. Given these models: class Group(models.Model): name = models.CharField() class Member(models.Model): name = models.CharField() group = models.ForeigKey(Group, blank=True, null=True) And this factory: class MemberFactory(factory.django.DjangoModelFactory): class Meta: model = Member name = factory.Sequence("Member {}".format) group = factory.Subfactory(GroupFactory) I would like the option of only creating a group if explicitly requested, but without losing all other features. In other words these should all work: MemberFactory() # Expect group=None MemberFactory(group=True) # Expect group=GroupFactory() MemberFactory(group__name="ABC") MemberFactory(group=Group.objects.get(...)) -

How to query on values of foreign key in django

Django Rest Framework save multiple serializers in a celery task
Am using Django rest framework, Celery, and RabbitMQ for my aplication. I have a task that does some data processing and saves the results as objects in my Django application. The task has two different results that need to be saved, so two model serializers are needed. The problem is that when the task is performed only one of the models is being saved. I tried the method while it was not a celery task and it worked perfectly, and i don't know what changes when it is run as a task that it won't work any more. this is the code runned in the task: def createMBGSimulations(petition_id): ...

Django REST Framework: handle exception for custom permission class
I built a custom permission class in Django that verifies the remote IP address of the request. If the request IP is one that's allowed, the has_permission class returns True, otherwise it returns False and the view responds with status code 403.. class isVerifiedServer(permissions.BasePermission): def has_permission(self, request, view): ip_addr = request.META['REMOTE_ADDR'] return ip_addr == some_verified_ip But I want the view to return 404 when this test fails, which is what the server responds with by default when a request is sent to a non-existent URL endpoint. I want to do this to make sure no one can figure out what a valid endpoint is. DRF documentation says the following about changing the exception response of a custom permission class: Custom permissions will raise a PermissionDenied exception if the test fails. To change the error message associated with the exception, implement a message attribute directly on your custom permission. Otherwise the default_detail attribute from PermissionDenied will be used. Similarly, to change the code identifier associated with the exception, implement a code attribute directly on your custom permission - otherwise the default_code attribute from PermissionDenied will be used. I've tried setting many attributes to achieve this, but the response is still always … -
Cannot get autocompletion on Django Model Manager in PyCharm
I'm trying to use autocompletion to get methods like filter, count, create, etc. in PyCharm, but I can't seem to grab them from the objects attribute. It seems like this specific attribute is not working - since PyCharm provides autocompletion for the class itself, for example, just not objects. I've tried refreshing the virtual environment as well, but it seems like it might just not be a supported features. It doesn't autocomplete in either Pycharm 2020.3 or Pycharm 2021.2., or in abstract or concrete classes. -

SELECT G.ID, G.DEFAULT_VAL, G.tag_flg,M.TRANSLATION_ID, M.language_id FROM translation.GLOSSARY G LEFT JOIN translation.GLOSSARY_TRANS_MAP M ON M.GLOSSARY_ID = G.ID and M.LANGUAGE_ID = {language_id} LEFT JOIN translation.GLOSSARY_TRANSLATION T ON T.ID = M.TRANSLATION_ID The models that I have are these: class ReportLanguage(models.Model): iso_cd = models.CharField(max_length=50) display_nm = models.CharField(max_length=50) class Meta: managed = False db_table = 'report_language' class Glossary(models.Model): placeholder = models.CharField(max_length=50) default_val = models.CharField(max_length=150) tag_flg = models.BooleanField() class Meta: managed = False db_table = 'glossary' class GlossaryTransMap(models.Model): glossary = models.ForeignKey('Glossary', models.DO_NOTHING) translation = models.ForeignKey('GlossaryTranslation', models.DO_NOTHING) language = models.ForeignKey('ReportLanguage', models.DO_NOTHING) class Meta: managed = False db_table = 'glossary_trans_map' class GlossaryTranslation(models.Model): translated_val = models.CharField(max_length=1000) crt_dts = models.DateTimeField() crt_user = models.CharField(max_length=255) upd_dts = models.DateTimeField() upd_user = models.CharField(max_length=255) glossary = models.ForeignKey('Glossary', models.DO_NOTHING) translation = models.ForeignKey('GlossaryTranslation', models.DO_NOTHING) class Meta: managed = False db_table = 'glossary_translation' I was able to get similar response as i get from the query with this orm all_glossaries = GlossaryTransMap.objects.select_related('translation', 'glossary', 'language').values( 'glossary__id', 'translation', 'language', default_val=F('glossary__default_val'), tag_flg=F('glossary__tag_flg')).filter(language__id=lang_id) Also the serializer that i created looks like this: class AllGlossariesData(serializers.ModelSerializer): id = serializers.SerializerMethodField() default_val = serializers.SerializerMethodField() tag_flg = serializers.SerializerMethodField() translation_id = serializers.SerializerMethodField() language_id = serializers.SerializerMethodField() class Meta: model = GlossaryTransMap fields = ['id', 'default_val', 'tag_flg','translation_id', … -
