Adding & updating users from django admin to Auth0
I am trying to use Auth0 authentication in my django application. I am able to see the users added from auth0 in my django custom user table. Is it possible to add and update users from django application to Auth0. So far my code is mostly from the auth0 django tutorial. Can we add users from django admin site with Abstract Base User model and show them in Auth0? Below is code for authentcation that I am using. But is it possible to do 2-way? If I update a user in django admin site, it is not reflecting in Auth0 users. I couldn't get a clear picture of the AUth0 management API to update users from django side.. especially from admin site. Any inputs would be of great help. auth0.py class Auth0(BaseOAuth2): """Auth0 OAuth authentication backend""" name = 'auth0' SCOPE_SEPARATOR = ' ' ACCESS_TOKEN_METHOD = 'POST' REDIRECT_STATE = False EXTRA_DATA = [ ('email', 'email') ] def authorization_url(self): return 'https://' + self.setting('DOMAIN') + '/authorize' def access_token_url(self): return 'https://' + self.setting('DOMAIN') + '/oauth/token' def get_user_id(self, details, response): """Return current user id.""" return details['user_id'] def get_user_details(self, response): # Obtain JWT and the keys to validate the signature id_token = response.get('id_token') jwks = request.urlopen('https://' … -

Django Rest Framework Path working for one link, but not for other with same setup
I am trying to access my mysql database through the django rest backend. My frontend uses Vue with Axios. More specifically, I have a junction table TeacherSubjectJunction, which I want to access through the following path to get all subjects for a teacherid. app/urls.py path('teacherssubjects/<int:teacherid>/', TeacherSubjectJunctionList.as_view()) views.py: class TeacherSubjectJunctionList(generics.ListAPIView): queryset = TeacherSubjectJunction.objects.all() serializer_class = TeacherSubjectJunctionDeepSerializer filterset_class = TeacherSubjectJunctionFilter serializer.py: class TeacherSubjectJunctionDeepSerializer(serializers.ModelSerializer): class Meta: model = TeacherSubjectJunction fields = ['teacherid', 'subjectid'] depth = 3 For Filtering i am using the third party library django-filter filters.py class TeacherSubjectJunctionFilter(filters.FilterSet): class Meta: model = TeacherSubjectJunction fields = ['teacherid', 'subjectid'] models.py class TeacherSubjectJunction(models.Model): pk_teachersubject = models.AutoField(primary_key=True) teacherid = models.ForeignKey(Teachers, models.CASCADE, db_column='TeacherID') subjectid = models.ForeignKey(Subjects, models.CASCADE, db_column='SubjectID') class Meta: db_table = 'teacher_subject_junction' In my Vue file I am trying to access this path with the following code: async getSubjectsforTeacher(teacher){ await getAPI.get('/teacherssubjects/?teacherid='+teacher) .then(response =>{ this.SubjectsforTeacherData[teacher] = response.data console.log(this.SubjectsforTeacherData) }).catch(error =>{ if (error.response){ console.log( error.response ) }else if(error.request){ console.log( error.request ) }else if(error.message){ console.log( error.message ) } }) } The above setup gives me the following error: GET http://127.0.0.1:8000/teacherssubjects/?teacherid=3 404 (Not Found) Since I am only a few months into drf, I figured that something about my url setup was wrong.

Django: list User details and Group for every User-Group (Many-To-Many) relationship in template
How to query and show User info and their Group for every User-Group (Many-To-Many) relationship in Django template? The result should look like: | User username | User email | Group name | | ------------- | -------------- | ----------- | | user1 | user1@mail.com | groupA | | user1 | user1@mail.com | groupB | | user2 | user2@mail.com | groupA | | user2 | user2@mail.com | groupC | | user3 | user3@mail.com | groupA | My question is similar to Vanilla Django Query to show 'flattened' User/Group (ManyToMany) Listing, but would like show more user details on the table. I naively thought something like this would have worked, but didn't. {% for group in groups %} {% for user in group.users.all %} <tr> <td>{{user.username}}</td> <td>{{user.email}}</td> <td>{{group.name}}</td> </tr> {% endfor %} {% endfor %} Using the raw SQL query has solved my problem: https://stackoverflow.com/a/38780451/991505 , but I am looking for better answers in the Django/Python way. -

Integrate a voip application to a website
I need for a project to integrate to a website ( django & vuejs ) a voice chat page where there could be one to one exchanges, or one to many, following a group logic. For example if people are spread in 4 groups A,B,C,D, there should be one 'push to talk' button where for A people such that only their group hears it, and one global push to talk button such that everyone receives it. I was thinking of implementing it in python using PyAudio and multicast sockets but not sure it is the best idea or if it is even doable... Any idea or remark is welcome ! I saw that WebRTC could have been an option however it implies joining rooms if im not mistaken, which would be a problem. Thank you for reading and have a great day! -

React Monaco Editor with python language server - Django Backend
all. I'm working on the project that uses Monaco editor (for python language) on React. But we want to implement IntelliSense to code editor, so it should suggest, autocomplete and so on.

I know we should use monaco-languageclient, but its docs are not enough and noting for django -

How to save the image in the ImageField field from the link given by the parser, optimize it, and rename it according to needs?
I faced such a problem because of my inability, lack of understanding. In general, I made myself a parser for certain sites with saving the image and optimization and using extra_felds so as not to save choose to the database. In general, I need the picture to be saved in ImageField, to be optimized, and if its temp file is saved to be deleted. from io import BytesIO from django.core.files.base import File from urllib import request from django import forms from .models import Mods from .utils import get_link_data, slugify """Форма для Файлов""" class AdminFileForm(forms.ModelForm): """Выбор площадки парсинга""" PARSER_CHOOSE = [ (None, 'Не выбрано'), ('2', 'Steam'), ('3', 'Nexus') ] """Моё поле, недобавленное в модель""" parser = forms.ChoiceField(choices=PARSER_CHOOSE) """Добавляем русское название""" def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['parser'].label = 'Площадка для парсинга' """Все поля из модели""" class Meta: model = Mods fields = '__all__' def clean(self): data = self.cleaned_data parser = data.get('parser', None) source = data['source'] if parser == self.PARSER_CHOOSE[1][0]: # Steam if source: # Source link to Steam mod title, version, author, link = get_link_data(source) data['title'] = title data['slug'] = slugify(title) data['author_file'] = author if not data['preview']: # ImageField from PIL import Image #parser img request_link = request.Request(link, headers={'User-Agent': 'Mozilla/5.0'}) input_file … -
Django get_FOO_display on template wont display
Good day SO. I am trying to use the get_FOO_display on template but my data is not displaying. Also, I have read other SO answers and I believe that I followed them to a T but not working. Please try to correct me what I do wrong. How I declared: Models: GENDER_CHOICES = ( (1, '男性'), (2, '女性'), ) gender = models.PositiveSmallIntegerField(choices=GENDER_CHOICES, default=0, null=False) forms: ... self.fields['gender'].widget.attrs.update({'class': 'form-control'}) view: account = AccountViewForm(initial = {"gender" : account.gender}) template: {{account.get_gender_display}} If I only use {{account.gender}}, it becomes a select tag with the correct data -
Django: How to return an attribute inside an HttpResponse with meta tags?
I have this return render(...) for the simple_upload view: def simple_upload(request): if request.method == 'POST' and request.FILES['myfile']: myfile = request.FILES['myfile'] fs = FileSystemStorage() filename = fs.save(myfile.name, myfile) uploaded_file_url = fs.url(filename) return render(request, 'simple_upload.html', { 'uploaded_file_url': uploaded_file_url }) return render(request, 'simple_upload.html') I would like to return something similar in the view complex_upload and be able to get the attribute 'uploaded_file_url' from complex_upload.html in the same way as I do with simple_upload.html but I don't know how to do it. Complex upload view: def complex_upload(request, filename): import os from mimetypes import MimeTypes content_type, encoding = MimeTypes().guess_type( os.path.basename(filename) ) if content_type is None or len(content_type) == 0: print(f'No content-type found for file: {filename}') content_type = 'text/plain' try: url = os.path.join( settings.MEDIA_ROOT, str(filename) ) with open(url.encode('utf-8'), 'rb') as f: uploaded_file_url = f.url(filename) resp = HttpResponse(f.read(), content_type=content_type) resp['X-Robots-Tag'] = 'noindex, nofollow' return resp except IOError as ex: data = {'ERROR': str(ex)} print(data) return JsonResponse(data) Is it possible to combine in a return a render with an attribute and a HttpResponse? What would be the proper way to do it? This question partially solves my doubts but it is not clear to me how to do something like that having meta tags.
