Filtering with wildcards in Django Rest Framework
I'm looking for a way to be able to filter my dataset in DRF using a wildcard. For example; I want to return any hostname in the below model that starts with 'gb'. I also have some requirements to search in the middle and the end of the hostname depending on usecase. I'd expect to be able to hi the following endpoint: /devices/?host_name=gb* and it return everything that has a host_name starting with gb. Model: class Device(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) host_name = models.CharField(max_length=64) mgmt_ip_address = models.GenericIPAddressField() domain_name = models.CharField(max_length=64) class Meta: ordering = ['host_name'] def __str__(self): return self.host_name Serializer: class DeviceSerializer(serializers.HyperlinkedModelSerializer): id = serializers.ReadOnlyField() class Meta: model = Device fields = '__all__' View: class DeviceViewSet(viewsets.ModelViewSet): permission_classes = (DjangoModelPermissions,) queryset = Device.objects.all() serializer_class = DeviceSerializer filter_backends = [DjangoFilterBackend, filters.rest_framework.DjangoFilterBackend, drf_filters.SearchFilter] filter_fields = ['id', 'host_name', 'mgmt_ip_address', ] I have tried creating custom filters but not sure that is the right approach since I haven't been able to get it working. -
Using Django, should I implement two different url mapping logics in my REST API and web application, and how?
I have a Book model an instance of which several instances of a Chapter model can be linked through Foreign Key: class Book(models.Model): pass class Chapter(models.Model): book = models.ForeignKey(to=Book, ...) class Meta: order_with_respect_to = "book" I decided to use Django both for the RESTful API, using Django Rest Framework, and for the web application, using Django Template. I want them separate as the way should be open for another potential application to consume the API. For several reasons including administration purposes, the API calls for a url mapping logic of this kind: mylibrary.org/api/books/ mylibrary.org/api/books/<book_id>/ mylibrary.org/api/chapters/ mylibrary.org/api/chapters/<chapter_id>/ For my web application, however, I would like the user to access the books and their contents through this url mapping logic: mylibrary.org/books/ mylibrary.org/books/<book_id>-esthetic-slug/ mylibrary.org/books/<book_id>-esthetic-slug/chapter_<chapter_order>/ The idea is the router to fetch the book from the <book_id>, whatever the slug might be, and the chapter according to its order and not its ID. Now I need some advice if this is desirable at all or if I am bound to encounter obstacles. For example, how and where should the web app's <book_id>/<chapter_order> be "translated" into the API's <chapter_id>? Or if I want the web app's list of books to offer automatically generated slugged links … -
Using value from URL in Form Wizard for Django
I'm trying to use this Form Wizard to design a multipage form in Django. I need to catch a value from the URL, which is a client's ID, and pass it to one of the Forms instance, as the form will be built dynamically with specific values for that client. I have tried redefining the method get_form_kwargs based on this thread, but this isn't working for me. I have the following code in my views.py: class NewScanWizard(CookieWizardView): def done(self, form_list, **kwargs): #some code def get_form_kwargs(self, step): kwargs = super(NewScanWizard, self).get_form_kwargs(step) if step == '1': #I just need client_id for step 1 kwargs['client_id'] = self.kwargs['client_id'] return kwargs Then, this is the code in forms.py: from django import forms from clients.models import KnownHosts from bson import ObjectId class SetNameForm(forms.Form): #Form for step 0 name = forms.CharField() class SetScopeForm(forms.Form): #Form for step 1, this is where I need to get client_id def __init__(self, *args, **kwargs): super(SetScopeForm, self).__init__(*args, **kwargs) client_id = kwargs['client_id'] clientHosts = KnownHosts.objects.filter(_id=ObjectId(client_id)) if clientHosts: for h in clientHosts.hosts: #some code to build the form When running this code, step 0 works perfectly. However, when submitting part 0 and getting part 1, I get the following error: _init_() got an unexpected keyword … -

How to handle excel file sent in POST request in Django?
I sent an excel file in a post request to my back-end and I tried handling the file using the following: def __handle_file(file): destination = open('./data.xslx', 'wb') for chunk in file.chunks(): destination.write(chunk) destination.close() However, the output from that is not an excel file. It is a collection of XML files. My end goal is to obtain a data frame from the file data that was sent so that I can extract the data. What is a clean way of handling this type of file? -

( without adding any new row ) How to solve this problem? Thank You :) -
How do I attach a PaymentMethod to a stripe Customer in DjStripe?
I have the following Django class: class PurchaseSubscriptionView(APIView): def post(self, request, user_id): price_name = request.data.get("price_name") payment_method = request.data.get("payment_method") user = User.objects.get(id=user_id) customer, created = djstripe.models.Customer.get_or_create(subscriber=user) payment_method_json = json.dumps(payment_method) customer.add_payment_method(payment_method_json) price = djstripe.models.Price.objects.get(nickname=price_name) customer.subscribe(price=price) Everything works until customer.add_payment_method(payment_method_json) At which point I get: stripe.error.InvalidRequestError: Request req_8KcCUrPg7z8Aok: No such PaymentMethod: '{\"id\": \"pm_1IaFMyJs57u3g5HDGoe83cGx\", \"object\": \"payment_method\", \"billing_details\": {\"address\": {\"city\": null, \"country\": null, \"line1\": null, \"line2\": null, \"postal_code\": null, \"state\": null}, \"email\": null, \"name\": null, \"phone\": null}, \"card\": {\"brand\": \"visa\", \"checks\": {\"address_line1_check\": null, \"address_postal_code_check\": null, \"cvc_check\": null}, \"country\": \"US\", \"exp_month\": 2, \"exp_year\": 2022, \"funding\": \"credit\", \"generated_from\": null, \"last4\": \"4242\", \"networks\": {\"available\": [\"visa\"], \"preferred\": null}, \"three_d_secure_usage\": {\"supported\": true}, \"wallet\": null}, \"created\": 1617002320, \"customer\": null, \"livemode\": false, \"type\": \"card\"}' What exactly is going on? I passed the PaymentMethod from my client after generating it - this should work, correct? Am I missing any steps?
