password_reset does not pick from_email
I have my email setup for entire django project and it works fine. When it comes to reset password in the following url: http://127.0.0.1:8000/rest-auth/password_reset/ and after submitting the email, it throws: SMTPDataError at /rest-auth/password_reset/ (550, b'The from address does not match a verified Sender Identity.

Django form does'nt render even if the code seems alright
I am beginner to Django. I have just started learning basic forms and here is the code which does'nt work. The method specified for the form in form_page.html is POST, so accordingly in views.py it must render me form_page.html but instead it prints thanks which means it does'nt recognize the method as post and run the else code snippet.Can you help me fix it!!

How can I bundle my JSON API data into one dictionary?
I'm trying to package my API data into one GET request simply using standard libraries python. class GetData(APIView): def get(self, request, *args, **kwargs): urls = [url_1, url_2, url_3, url_4 ] data_bundle = [] for x in urls: response = requests.get(x, headers={'Content-Type': 'application/json'}).json() data_bundle.append(response) return Response(data_bundle, status=status.HTTP_200_OK) The return response has to be JSON data, I'm trying to get it to work but it seems like the response data seems to be overiding eachother? How can I properly create a JSON dictionary of dictionaries. I've tried switching data_bundle to an empty dictionary instead of a list. However that just caused an error saying: ValueError: dictionary update sequence element #0 has length 8; 2 is required Is there a simple way to accomplish this that I'm missing? Thank you for the help. -
Django. How to design model so not to have vertical repetition for common name and family name?
In the below model there are fields like name and family name that will be repeated. For example Jhon or Jack would be common name which are bound to repeat themselves. Is there any better way to avoid this or this is ok by normalization standards of data models designs? class PropertyOwner(models.Model): name = models.CharField(max_length=200) family_name = models.CharField(max_length=200) contact_number = models.PositiveIntegerField() email = models.EmailField() def __str__(self): return self.name Is the fact that some names and family names will repeat themselves be a problem or better way to do this? -

Flatpickr datetime field showing the wrong date in Edit form

Django: values_list(flat=True) but for multiple fields
I have a model, TestModel As far as I know, if I were to implement TestModel.objects.values_list('FieldA', flat=True) This results in [A,B,C,(...)] (a list) And doing this TestModel.objects.values_list('FieldA','FieldB') results in [(A,1),(B,2),(C,3),(...)] (a list of querysets) But is it possible to get a similar result to Flat=True but for multiple fields? So, if I were to use something like testQS = TestModel.objects.values_list('FieldA','FieldB') and call testQS['FieldA'], this will return [A,B,C,(...)] Likewise, calling testQS['FieldB'] will return [1,2,3,(...)] Basically, I want to get all the data from a certain field in a values_list with multiple fields without resorting to for loop or creating values_list multiple times for each field. -
Cannot see my object models in Django admin view
I'm a relative Noobie at Django and have an issue with the admin interface. I am not able to see any of my custom object models, but I can see only the 'Groups' (under Authentication & Authorization), and 'Users' objects (under my 'CrushIt' app) (based on 'abstractuser') I used the startproject script to create my project (wedgeit) and app (CrushIt), and have gone through all the tips in the Django admin documentation, to try to troubleshoot the issue (see below). I also went through all the queries from other users I could find, but I'm still stuck. P.S. I can see my models from the shell and can create instances also, but they don't appear in the admin interface. Any hints would be appreciated.

Is possible to implement this function with a single django ORM query?
I'm making an aggregate report of stores, categories and customers for an ecommerce. Basically, I'm trying to achieve what this function does: from django.db.models import ExpressionWrapper, DecimalField, F, Sum from .models import Order def get_report_data(stores, categories, customers): result = [] for store in stores: for category in categories: for customer in customers: total = Order.objects.filter( store=store, orderitem__product__category=category, customer=customer, ).aggregate( total=Sum( ExpressionWrapper( F("orderitem__product__price") * F("orderitem__quantity"), output_field=DecimalField(), ) ) )["total"] result.append([store, customer, category, total]) return result Obviously, this is efficiently poor and I'm trying to turn this function into a query. I've tried the following, but I know I'm missing the mark by A LOT. total = ( Order.objects.filter( store__in=stores, customer__in=customers, orderitem__product__category__in=categories, ) .values("store", "orderitem__product__category") .annotate( total=Sum( ExpressionWrapper( F("orderitem__product__price") * F("orderitem__quantity"), output_field=DecimalField(), ) ) ) ) How should I proceed?

Bokeh rendering glitchy (long complex visualization), embedded in Django

Is there a way to retrieve Enum description instead of name in a GraphQL API made with Django Graphene
This question is more about what's the best practice than how to monkey-patch Graphene to accomplish what I want. Django Graphene turns model's choices automagically in enums. Lets say I have this model: class Car(models.Model): brand = models.PositiveSmallIntegerField( choices=( (1, "Audi"), (2, "Mercedes Benz"), (3, "BMW") ) ) with this node: class CarNode(DjangoObjectType): class Meta: model = Car filter_fields = [] interfaces = (relay.Node,) then, running the following query: query Cars { cars { edges { node { id brand } } } } results in this response: { "data": { "cars": { "edges": [ { "node": { "id": "Q2FyTm9kZTox", "brand": "A_1" } }, { "node": { "id": "Q2FyTm9kZToy", "brand": "A_2" } }, { "node": { "id": "Q2FyTm9kZToz", "brand": "A_3" } } ] } } } At this point I may want to make a custom enum to turn A_1, A_2 and A_3 into capitalized, snake cased values, to make them self-descriptive... class CarBrand(graphene.Enum): AUDI = 1 MERCEDES_BENZ = 2 BMW = 3 @property def description(self): if self == CarBrand.AUDI: return 'Audi' if self == CarBrand.MERCEDES_BENZ: return 'Mercedes Benz' if self == CarBrand.BMW: return 'BMW' return 'Other brand' class CarNode(DjangoObjectType): brand = CarBrand() ... Now, the response looks A LOT … -
unable to access private repos with oauth access token
i have created a Oauth github app and Oauth works fine. but i want to access the all repos(including private) with the access-token i get during Oauth. i have tried with personal access token and i am getting all the private reops. why its not working with Oauth access-token ? Scops SOCIALACCOUNT_PROVIDERS = { 'github': { 'SCOPE': [ 'user', 'repo' ], } } regarding the env. i am using dj-rest-auth to authenticate with Github and get the access-token.
