Combine SAML mapping with Djangosaml2
I have at least 2 Django apps I'm using with a SAML SSO using simpleSAMLphp as IDP and Djangosaml2 as SP. In general auth is working, despite some issues not relevant for this issue. Both apps are using a different user model. This is the SAML mapping I use for one app: SAML_ATTRIBUTE_MAPPING = { 'uid': ('username', ), 'mail': ('email', ), 'givenName': ('first_name', ), 'sn': ('last_name', ), 'is_staff': ('is_staff', ), 'is_superuser': ('is_superuser', ), } And here for the other SAML_ATTRIBUTE_MAPPING = { 'mail': ('email', ), 'givenName': ('nick', ), 'sn': ('name', ), 'is_staff': ('is_staff', ), 'is_superuser': ('is_superuser', ), } This is working ok. But the fields are not what they are meant for. What I would like to achieve is to combine givenName and sn into a single value which I can save in the name field of the user model. Looking at the Djangosaml2 docs, it mentioned a signal which could be used for it from djangosaml2.signals import pre_user_save def custom_update_user(sender=User, instance, attributes, user_modified, **kargs) ... return True # I modified the user object But i don't know where this should go, and how to work with the data this signal receives. Or does anyone know a better way to … -
wagtail AbstractImage, ParentalManyToManyField and ClusterableModel
Using wagtail 2.1, django 2.0.3, python 3.6.4 I have the following (simplified) custom image model, linked to PhotoType and PhotoPlate via m2m relationships: from wagtail.images.models import AbstractImage from modelcluster.fields import ParentalManyToManyField from modelcluster.models import ClusterableModel class PhotoType(models.Model): title = models.CharField(verbose_name='Title', max_length=255, blank=False, null=False, default=None) class PhotoPlate(models.Model): plate= models.CharField(verbose_name='Title', max_length=255, blank=False, null=False, default=None) class Photo(AbstractImage): type = ParentalManyToManyField(PhotoType, help_text="Several are allowed.", blank=True) plate = ParentalManyToManyField(PhotoPlate, help_text="Several are allowed.", blank=True) class Meta: verbose_name = 'Photo' verbose_name_plural = 'Photos' The PhotoType and PhotoPlate models are referenced via modeladmin_register(CCAPhotoTypeModelAdmin) and modeladmin_register(CCAPhotoPlateModelAdmin) in the local wagtail_hooks.py file. All works fine after following the documentation. Except for one thing: no matter how many items are selected in the multiple choice dropdown that are rendered for the two fields type and plate, the corresponding m2m relationship is never saved. I found a few answers, but could get it to work by playing with the inheritance of the Photo class, for example: class CCAPhoto(ClusterableModel, AbstractImage). Is there anyway to add a ParentalManyToManyField to a custom image model? If so, what am I missing? -

Implementation of Social Oauth2 rest-framework for combining Django and social accounts
I am currently working on a login mechanism for the web application. This is the separation of the frontend (Vue) + Django DRF backend. And I wanted to use the django-rest-framework-social-oauth2 library to implement something identical that we can see eg in the Evernote application. The user can choose to start an account from scratch or login via Google. Ok, it's great that if I create an account on the Evernote website, I can immediately connect them to the Google account. It is in this case how such communication would look on the side of Vue - Django if I wanted to do it from the beginning based on REST My plan was as follows The user establishes an account by completing the registration form In this way I get a login, password, etc. in my django User table After logging in to the account, he sees his website and the option to connect from Facebook. After choose this option and send a query curl -X POST -d "grant_type=convert_token&client_id=&client_secret=&backend=&token=" http://localhost:8000/auth/convert-token Reply: { "access_token": "c3JQjkkAOx8d0ZSyEgP6Hyh2hX3R66", "expires_in": 36000, "token_type": "Bearer", "scope": "read write", "refresh_token": "7qawsbmQHgOv5vYjzorAXOeA0d2vla" } Of course, before that, you get an access token from facebook using the JS SDK .. … -

Django Channels - constantly send data to client from server
Please take a look at this example. As you can see, some sort of event is constantly being sent to the client. I want to imitate this using Django-Channels, inside consumers.py. Here's a simplified version of what I have: class ChatConsumer(AsyncConsumer): async def ws_connect(self, event): self.send = get_db_object() .... await self.send({ "type": "websocket.accept" }) # I need to CONSTANTLY receive & send data async def ws_receive(self, event): obj = ...# query DB and get the newest object json_obj = { 'field_1': obj.field_1, 'field_2': obj.field_2, } await self.send({ "type": "websocket.send", "text": json.dumps(json_obj) }) @database_sync_to_async def get_db_object(self, **kwargs): return Some_Model.objects.get(**kwargs)[0] Here, I want my Django backend to constantly: Query DB Receive obj from DB Send the received obj to Front-End websocket as event How can I achieve this? The important thing is that I need to CONSTANTLY send data to client. Most of the Django-Channels resources on the internet covers only Chat Apps, which doesn't necessarily constantly send data to client. I couldn't find any working codes that does this job. Please, no more recommendation for redis or channels documentation... or some random 3rd party libraries that lacks good documentation.... It's easy to recommend but hard to implement. However, if there's an … -

Case() in Django return a Type error
I'm trying to use a huge request to minimize the number of requests in my app. In my database I have some cards, each card has multiple amounts link to it, and each amount is linked to a category. I try to get the Sum of amounts for a category between 2 dates and the same thing for 2 previous dates (dates are in cards) compare them and get the percentage evolution. Everything works fine for all cases but one: If my sum for a category is 0 for the previous period, I have an error "Divide by 0" when I try to calculate the evolution. So I tried to get the evolution, only if the sum of the previous period is != 0, for this I use Case(When()). But I have an error and I'm not sure to understand why. Here my request: categories = Category.objects.filter( Q(amount__card__date__range=( start_day_compare, stop_day_compare )) | Q(amount__card__date__range=( previous_start_day_compare, previous_stop_day_compare )) ).annotate( somme=Sum( 'amount__amount', filter=Q( amount__card__date__range=( start_day_compare, stop_day_compare ) ) ), evolution=Case( When( Sum( 'amount__amount', filter=Q( amount__card__date__range=( previous_start_day_compare, previous_stop_day_compare ) ) ) != 0, then=Value( ( ( Sum( 'amount__amount', filter=Q( amount__card__date__range=( start_day_compare, stop_day_compare ) ) ) - Sum( 'amount__amount', filter=Q( amount__card__date__range=( previous_start_day_compare, previous_stop_day_compare ) ) … -

Django - Nothing happens when "submit" button is clicked in a ModelForm?

Django Include() in urls.py with two apps
I believe this is a simple question but I am having a hard time figuring out why this is not working. I have a django project and I've added a second app (sales). Prior to the second app, my urls.py simply routed everything to the first app (chart) with the following: urlpatterns = [ path('admin/', admin.site.urls), path('', include('chart.urls')), ] and it worked fine. I have read the docs over and over a looked at many tutorials, so my impression is that I can simply amend the urls.py to include: urlpatterns = [ path('admin/', admin.site.urls), path('sales/', include('sales.urls')), path('', include('chart.urls')), ] and it should first look for a url with sales/ and if it finds that then it should route it to sales.urls, and if it doesn't find that then move on and route it to chart.urls. However, when I load this and type in 127.0.0.1:8000/sales, it returns the following error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/sales/ Raised by: chart.views.index which tells me that it is not routing my sales/ url to sales.urls but to chart.urls.

writing a for loop for each individual case of a models field using a queryset of models
So, basically in my program i have a cart, then payments which have a Foreign key of "cart" now my cart has a price and each payment has an amount, so a user can pay in multiple payments for a cart. I've been asked to write a page that totals up the amount of all payments which are linked to a specific order then display the carts that haven't been fully paid yet, so i need to write a for loop that is basically foreach unique cart_id in payments.cart_ids compare cart_id.price to sum(payments.amount where payments.cart_id = cart_id) any idea on how to actually go about this? -

Currently, I have to handle a webhook sent from Stripe and therefore I have to reverse this. Meaning 52334 CENTS into 523.34 USD. I am a bit stuck with that and wonder if anyone could help me how I can reverse this calculation with my funciton: def smallest_currency_unit(large_currency_amount, iso_code): iso_code = iso_code.upper() exponent = iso4217.Currency(iso_code).exponent if exponent == 0: # 0 signals unused/nonexistent minor currency return int(large_currency_amount) return int(large_currency_amount * (10 ** exponent))
