get csrf token in react native
I have built django server to manage my data, then I have desktop react app where I can create new users/login/post data, it works flawless, It is based on csrf token verification and there is no problem with that. However I have also react-native app which is supposed to let user log in, and GET data which belongs to him. And here is question, how to get CSRF token in react native? In desktop app it looks more or less like this but I have no idea how to login in react native as I can't simply get Cookie with csrf token. componentDidMount() { const csrfToken = Cookies.get('csrftoken') this.setState({csrfToken}) } loginHandler = login_data => { this.setState({ user: login_data.user, password: login_data.password }, () => { const auth = { "username": this.state.user, "password": this.state.password } fetch("http://localhost:8000/data/", { method: 'POST', credentials: 'include', headers: { "X-CSRFToken": this.state.csrfToken, }, body: JSON.stringify(auth) }) .then((res) => res.json()) .then(resp => console.log(resp)) .then(() => this.getData()) .catch(() => this.setState({ user: "", passowrd: "" })) }) }; -

Django: ask for ideas about realising rotation of timetables
I am trying to use Django to create a rotated timetable: 1) there are lessons with various durations (30 mins, 45 mins, 60 mins etc); 2) there several tutors; 3) the tutor login their account, they will see a timetable; 4) the students should be rotated, for example: Week 1: Student A: 09:00 - 09:30 (a 30 min lesson) Student B: 09:30 - 10:15 (a 45 min lesson) Student C: 10:15 - 10:45 (a 30 min lesson) and so on ... ...

how to post data into database using views in django without template

Django: how to synchronize 2 db?
I have a Django project which is connected to 2 db. models.py class ModelOne(models.Model): db = "firstDB" attr = someValue class ModelTwo(models.Model): db = "secondDB" attr = {cannot do ForeignKey(ModelOne)} I would like to make them synchronous, such that table/data changed in 1st db, it should also change it in 2nd. As far as I know, Django does not allow to create a model that has an attribute that references another db. I have written the script that goes through 1st db and creates model instances in 2nd db: import os, django, requests os.environ.setdefault("DJANGO_SETTINGS_MODULE", "diary.settings") django.setup() URL = "APIendpointToCreateModelTwo" data = models.ModelOne.objects.all() for school in schools: data = {...} requests.post(url = URL, data = data) It works well, however, I need it to be done periodically (e.g. once in a day) or directly make changes into the 2nd db, when 1st is varied. I was wondering, if I apply the same script logic to other actions, will it be time consuming task? Maybe there are other techniques that allows to implement that, like adding a function that listens for the changes in the 1st db, and implements them directly. I have found technologies such as celery, redis, cron, however I'm … -
How to validate mp4 file or audio files in general with python?
I have a rest API built with Django rest framework, one of its serializers is to accept Base64file which is our audio file, now what I want is simply check and validate the decoded file so I can know if this a valid mp4 or any audio type in general or not. the problem is, sometimes the audio file after upload and save is corrupted and can't be played, so doing this validation is essential to make sure that the file is sent correctly or it was sent corrupted at first place. I have been digging on google and the Internet searching for anything can do this simple task but all I found was how to play audio or manipulate it, I didn't even find something that may raise an exception if the file is not valid when trying to open it. for more info. I'm using django-extra-fields, I use Base64FileField to implement my Audio file field, they provided an example to do so for like PDF's, I'm trying to do this similar way for audio but what is holding me is doing the check for audio. The example of PDF: class PDFBase64File(Base64FileField): ALLOWED_TYPES = ['pdf'] def get_file_extension(self, filename, decoded_file): … -
Is it possible to use a django viewset with two serializers?
I have a model for Articles which has a lot of fields. When someone fetches a specific article by id I want to send almost all of the fields back to the client. However, when the articles list is generated I don't want to send all of the articles with all of that data, but rather limit each article to a few important listing fields, and forgo long fields like content etc.. Can I achieve these with an elegant tweak to the the django_restframework.viewsets module, or should I just build the api methods myself using django_restframwork.generics instead? example: # articles/api/urls.py # # -------------------- # from articles.api.views import ArticlesViewSet from django.urls import path from rest_framework.routers import DefaultRouter router = DefaultRouter() router.register(r'', ArticlesViewSet, basename='articles') urlpatterns = router.urls # articles/api/views.py # # --------------------- # from rest_framework.viewsets import ModelViewSet from ..models import Article from .serializers import ArticleSerializerFull, ArticleSerializerShort class ArticlesViewSet(ModelViewSet): # Perhaps some conditional code here? serializer_class = ArticleSerializerFull queryset = Article.objects.all() -
Does editable=false apply at the database level?
When fields are set to editable=False, the docs say: If False, the field will not be displayed in the admin or any other ModelForm. They are also skipped during model validation. Default is True. Are any restrictions placed on the database itself, or is this simply restrictions on the client side? If not, is there a way to enforce this integrity of non-editable fields at the database level? -
How to parse request JSON data for DRF Serializer in custom format?
I have DRF serializer that looks like this: class LoginSerializer(serializers.Serializer): email = serializers.EmailField() password = serializers.CharField() def validate(self, attrs): user = authenticate(username=attrs['email'], password=attrs['password']) if not user: raise serializers.ValidationError('Incorrect email or password.') if not user.is_active: raise serializers.ValidationError('User is disabled.') return user When POST request is made to API it sends following JSON: { "email": "user@example.com", "password": "somepassword" } Due to certain project conventions I want that data for deserialization to be included inside request object and sent to API in following format: { "request": { "email": "user@example.com", "password": "somepassword" } } How I can make DRF's serializers (both Serializer and ModelSerializer) automatically fetch data from request block without writing additional serializer with nested LoginSerializer?: class LoginSerializer(serializers.Serializer): email = serializers.EmailField() password = serializers.CharField() def validate(self, attrs): user = authenticate(username=attrs['email'], password=attrs['password']) if not user: raise serializers.ValidationError('Incorrect email or password.') if not user.is_active: raise serializers.ValidationError('User is disabled.') return user class LoginRequestSerializer(serializers.Serializer): request = LoginSerializer() Is there some type of RequestRenderer that I need to implement in my APIView? -

How to compare user input to corresponding model field django
I'm trying to make learning app for myself and part of my plan is to make a quiz module. My problem is, that I don't know how to compare user answer with the correct answer that's stored in the model. Now, the only thing I've tried (except reading docs and stack overflow) was to inject the related model question inside of my HTML to later use in views.py, but from the beginning I felt like that's not the way it should work, so I guess I have to reorganize my models/forms or inside of views.py there is some way to query database for that specific model instance that I don't know. Here is my code Models: class Question(models.Model): question = models.CharField(max_length=100, unique=True) answer = models.CharField(max_length=100, unique=False) def __str__(self): return self.question Forms: class Answer(forms.Form): answer = forms.CharField() Views: def quiz(request): questions = Question.objects.order_by('question') form = Answer() context_dict = {'form':form,'questions':questions} if request.method == 'POST': form = Answer(request.POST) if form.is_valid(): #Here I want to make the comparison pass return render(request,"quiz_app/quiz.html",context_dict) HTML: <table> {% for q in questions %} <tr> <td>{{ q.question }}</td> <form method="POST"> <td>{{ form.answer }}</td> {% csrf_token %} <td> <input type="submit" value="submit"> </td> </form> </tr> {% endfor %} </table> -

Django admin custom serarch filter or unicode handling

I think I should make custome search_fields callback though, I am not sure how to do this. -

I want to have multiple organizations that are unique. core/models.py class Organization(models.Model): name = models.CharField(max_length=255, unique=True) user = models.ForeignKey(User, on_delete=models.CASCADE) address = models.CharField(max_length=1000, default=None) is_billed = models.BooleanField(default=False) def __str__(self): return f'{self.name} Organization' core/forms.py class OrganizationForm(forms.ModelForm): class Meta: model = models.Organization fields = ('name', 'address') core/views.py def save_organization_form(request, form, template_name): data = dict() if request.method == 'POST': if form.is_valid(): stock = form.save(commit=False) stock.user = request.user stock.save() data['form_is_valid'] = True organizations = Organization.objects.all() data['html_book_list'] = render_to_string('core/includes/partial_organization_list.html', { 'organizations': organizations }) else: data['form_is_valid'] = False context = {'form': form} data['html_form'] = render_to_string(template_name, context, request=request) return JsonResponse(data) @login_required(login_url="/accounts/login/") def organization_create(request): if request.method == 'POST': form = OrganizationForm(request.POST) else: form = OrganizationForm() return save_organization_form(request, form, 'core/includes/partial_organization_create.html') And when I add a new organization I get the following error: django.db.utils.IntegrityError: UNIQUE constraint failed: core_organization.name How do I fix this?
