Stripe payment in django form wizard
Does anyone have any experience with requesting a Stripe payment as part of a form wizard in Django? As far as I can tell, the only way to show the user an error when their card is rejected (for instance) when using the wizard is to create the charge in the clean() method of the form - but the wizard calls clean() on the form twice, causing even a valid card to be rejected because the charge is using the same token each time. Obviously it's not ideal to be creating the charge in the form's clean() method but I can't see how to do it outside of there and still be able to show any errors on the individual step in question. Any ideas? -
Does django-sorcery support connection pooling?
I'm playing around with django-sorcery, and so far it looks to me like I'm only getting one persistent connection into the database. Does django-sorcery support connection pooling? If so, how do I control the number of open connections available in the pool? -
Using two different serializer in one endpoint django rest framework
I'm trying to use two different serializers in endpoint but the second serializer that i assign(UserSerializer) is the one that is getting used. Is there a way to have one specific serializer being used for one specific model so that i can use userSerializer for creating a user and the CategorySerializer to create a category. class UserSignup(generics.CreateAPIView): model = Category serializer_class = CategorySerializer model = User serializer_class = UserSerializer def create(self, request): data = request.data category_serializer = self.get_serializer(data=request.data, many=True) user_serializer = self.get_serializer(data=request.data, many=True) -
Django Two Factor Authentication And Twilio
I've been playing with variations of this code for a couple days now....I have successfully set up django two factor authentication on my Windows 10 Pro OS so that it's successfully passing codes in my system log so that I can leverage the fake gateway defined in my settings.py file as shown below. TWO_FACTOR_CALL_GATEWAY = 'two_factor.gateways.fake.Fake' TWO_FACTOR_SMS_GATEWAY = 'two_factor.gateways.fake.Fake' LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', }, }, 'loggers': { 'two_factor': { 'handlers': ['console'], 'level': 'INFO', } } } This works flawlessly. The challenge has surfaced when I'm trying to use Twilio to essentially get two factor to work through Twilio. Here is the django two-factor instructions that I used to get two-factor working fine on my Windows machine...https://django-two-factor-auth.readthedocs.io/en/stable/configuration.html I have also set up a test Twilio account...as well as an Authy account on my device...but something seems to be a miss...I can't quite figure out how to pull this all together. The Twilio quickstart instructions that I found here...https://www.twilio.com/docs/authy/quickstart/two-factor-authentication-python-django Seem to be lacking when it comes to cloning and installing the application. Apparently a pip install isn't an option? I feel like this is where the lack of information or lack … -

Django abstract model inheritance - make all fields nullable in one child
I have an AbstractModel, Model and DraftModel. I need DraftModel to inherit from AbstractModel, but all inherited fields should be null=True. I can't change Model fields to null=True since there is too much logic built on that. I prefer not overriding manually all fields. I tried: def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) for field in self._meta.fields: field.null = True Which does not work, do you have any idea? -

How can I embed Django REST API documentation on the Angular landing page?
Any ideas how can I embed Django Swagger Documentation or built-in documentation on the Angular frontend? I mean by clicking documentation button on the landing page the user will be routed to the swagger documentation in the area of the same domain. At the moment I can redirect the user for instance from frontenddomain to backenddomain/doc but it may be bothersome because new tab will be opened in the web browser. Maybe you could recommend other solution than Swagger? I just to want display the user all the endpoints of the api in my landing page. Any ideas? -
Serializing an SQL Function in Django REST
I'm using Django and Django Rest Framework to build an API. I have a custom PostgreSQL function like this: myfunction(from_date, to_date) It simply calculates a figure from records in the date range in reviews table. How can I (safely!) take from_date and to_date from URL query parameters, pass them to the function, and return the (float) result via the API? I have made a simple model to hold the float, like this: class Result(models.Model): result = models.FloatField(default=0) class Meta: managed = False Alternatively, could I forgo the SQL function and implement this directly in Django/REST itself? I already have a model for reviews. In the view for result can I pull my_records from a date range, calculate it, and return the value as a serialized result response? As an end result, I want to be able to curl http://my.api/result?from=2019-03-01&to=2019-04-01 and get the result. Thank you. -
Optimising django queries to avoid duplicates when using detail view and overriding get_context_data
I'm trying to reduce the number of duplicated queries when using CBVs such as DetailView and then overriding get_context_data to filter a model based on related models. Right now, I have a DetailView for a PatientCase model and want to create two variables in the context for a related model CasePhotos the relationship is via a foreignkey on the CasePhoto model. class CasePhoto(models.Model): ... patient_case = models.ForeignKey(PatientCase, on_delete=models.CASCADE) photo = models.URLField() is_mentor_edit = models.BooleanField(default=False) ... Now, I know this is bad, but I cannot seem to find the correct optimal way to do this. Some guidance and even better some documentation links that I've obviously overlooked somewhere would be even better. class ReviewCaseView(DetailView): model = PatientCase def get_context_data(self, **kwargs): patient_case = self.get_object() context = super().get_context_data(**kwargs) case_photos = CasePhoto.objects.filter(patient_case=patient_case) context['case_photos'] = case_photos.filter(is_mentor_edit=False) context['mentor_photos'] = case_photos.filter(is_mentor_edit=True) return context I know that the duplication is line 5 patient_case = self.get_object() as detail.py calls get_object which is what creates the first query. Is there a way of caching this to reuse in get_context_data or maybe a better way without get_context_data at all? -

django 2.0 content management system
