What is the best practice to architect tasks processing using aws?
I'm going to process background tasks such as text transmission and email transmission as lambda. I thought of three ways, which is the best way? The biggest concern is whether to directly invoke Lambda in the app or use task consumer using sqs or sns . Or do you have any suggestions?enter image description here -
Django override QuerySet for pk
I'm using djongo in order to connect my Django Rest Framework project to MongoDB, As MongoDB using _id as its primary key, I changed my models like this: from djongo import models class MyModel(models.Model): _id = models.ObjectIdField(primary_key=True) name = models.CharField(max_length=200) When I query data from database, the type of _id will be bson.objectid.ObjectId So any time I want to query anything, I should do it like this: from bson.objectid import ObjectId from myapp.models import MyModel MyModel.objects.get(pk=ObjectId('606e91bd371197379e9bf919')) # or MyModel.objects.filter(_id=ObjectId('606e91bd371197379e9bf919')) and if I use MyModel.objects.filter(pk='606e91bd371197379e9bf919') it can't find the data in database This additional ObjectId which is required for any query makes many problems because none of the pre-existing classes (like Forms, Views, Django Rest Framework Serializers, ....) act like that, so I should override all of them, and this cause many code duplications, Is there a way to override any of Q/QuerySet/Model/Model Meta Class or a wrapper or anything else to apply the additional ObjectId for querying pk/id/_id field and solve this problem? Is a better way to do this? -

Ignore invalid foreign for django migrations?
I'm migrating an application from an old DB system to django. I've imported a bunch of legacy data. I used a script to convert the table schemas from the old system into Django models, as it had a lots of tables. Then I used another script to write the content of the old db into Django fixtures, which I then imported. That all worked fine, the data is served in the views etc. However, I now noticed that some ForeignKey in the old system were not properly identified as FK and were simply put in as Char/Int fields into the djando models. So I updated a field from IntegerField to ForeignKey, but that being legacy data I had the following issue: django.db.utils.IntegrityError: The row in table 'pickings_detpick' with primary key '17170' has an invalid foreign key: pickings_detpick.fk_ent_id contains a value '30223' that does not have a corresponding value in pickings_entpick.id. So basically, there are a number of (unsure how many yet) foreign key references that point to objects that actually do not exist in the source data (for whatever reason, I don't know the hold system much). Is there a way that I can simply tell Django to ignore those … -
Make URLfield display an error instead of just being red, with invalid validator
I have an URL-field, when I enter an invalid URL (without http) it just displays a red border around the field like so. If I click "submit" it does says "enter a valid url". Since some persons does not know, that http is required to be "valid" I want to add that as a message below, just like when calling clean_link raises an validation error. How can I do that, apart from removing the validation and add that step in clean_field instead? -
Django Redirect back two pages
I have a decorator protecting certain parts of my site. def admin_only(view): @wraps(view) def _view(request, *args, **kwargs): if not Group.objects.get(name='admin') in request.user.groups.all(): return redirect('main:unauthorized') return view(request, *args, **kwargs) return _view So if the user is not in the admin group, they are redirected to a view that renders an 'unauthorized blah blah blah template'. What I want to do is redirect the user back to where they were when they tried to access the forbidden page. I'll then use something like if not Group.objects.get(name='admin') in request.user.groups.all(): messages.error("Unauthorized blah blah blah" **redirect to where they were or home incase they used direct link** -

DRF queryset to return specific field
I'm creating a django rest framework application with this structure (assuming imports are correct, so I omit them from the code below. models.py: class Door(models.Model): type = models.CharField(max_length=40) color = models.CharField(max_length=40) serializers.py: class DoorSerializer(serializers.ModelSerializer): class Meta: model = Door fields = ['type', 'color'] views.py: class DoorViewSet(viewsets.ModelViewSet): serializer_class = DoorSerializer queryset = Door.objects.all() def get_queryset(self, *args, **kwargs): queryset = Door.objects.all() parameter = self.request.query_params.get('type', '') if parameter: return queryset.filter(type=parameter) else: return queryset So far this behaves as intended, when I make an api call to localhost/Doors it lists all the doors. And when I make an api call to localhost/Doors/?type=big it lists all the doors that have the value "big" in their "type" field. The addition I would like to make is another parameter check which would return a list of all the unique door types that exist in the database. This can be achieved in the manage.py shell by using: Door.objects.all().values('type').distinct() My attempt was the following modifications to views.py: ... parameter = self.request.query.params.get('type', '') unique = self.request.query.params.get('unique', '') if parameter: ... elif unique: return Door.objects.all().values('type').distinct() ... My assumption was that this would return the same as Door.objects.all().values('type').distinct() when I make a call to localhost/Doors/?unique=whatever However I am getting the error: "Got … -

Why does Django auto_now_add fail with not null on insert or update
I am trying to implement a data warehouse. So the django system will query an api at regular intervals to update the database. I am using client ids as the primary key which might be the problem but when I do save I obviously want it to create or update. I get this error whatever I do! django.db.utils.IntegrityError: null value in column "created" violates not-null constraint So originally I just had my model like this: class PersonalTaxClient(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) invoice_client = models.ForeignKey(InvoiceClient, blank=True, null=True, on_delete=models.PROTECT) client_name = models.CharField(max_length=100) email = models.CharField(max_length=100) Then I tried: class PersonalTaxClient(models.Model): created = models.DateTimeField(editable=False) updated = models.DateTimeField() client_code = models.CharField(max_length=20, primary_key=True) invoice_client = models.ForeignKey(InvoiceClient, blank=True, null=True, on_delete=models.PROTECT) client_name = models.CharField(max_length=100) email = models.CharField(max_length=100) # history = HistoricalRecords() def save(self, *args, **kwargs): ''' On save, update timestamps ''' print(timezone.now()) if not self.client_code: self.created = timezone.now() self.modified = timezone.now() return super(PersonalTaxClient, self).save(*args, **kwargs) and try to update like this: >>> from sbsite.models import PersonalTaxClient >>> p = PersonalTaxClient(client_code="HHH001", client_name="Bob") >>> p.save() I get the same error.

Django child models don't inherit Meta inner class
I have two Django 3.0 models, one of which is a subclass of the other: # models.py class BaseCategory(models.Model): class Meta: verbose_name_plural = "categories" class Category(BaseCategory): # fields 'n' stuff Only the Category model is registered in the Admin # admin.py @admin.register(Category) class CategoryAdmin(admin.ModelAdmin): # stuff here In the Admin, the Category model is labeled "Categorys", despite the fact that it should have inherited the Meta inner class and its verbose_name_plural attribute from BaseCategory. In fact, if I copy the same code into the Category model, # models.py class Category(BaseCategory): class Meta: verbose_name_plural = "categories" # fields 'n' stuff the model is correctly labeled "Categories" in the Admin. This indicates that the Category class is not inheriting the Meta inner class of BaseCategory. Why does a child class not inherit the Meta inner class? Is there another way for me to only specify verbose_name_plural once instead of copying the exact same code into every child of BaseCategory? -
django-mssql-backend - Invalid connection string attribute (0)
OK, I'm slowly going crazy. I want to connect Django 3 to MSSQLv15 Server. Connection works if I use Trustedconnection=yes (using win credentials), it also works on Ubuntu if I'm using FreeTDS v7.4 but it won't work in Windows if I want to use service account or personal credentials without Trustedconnection.

when exactly django query execution occures
In a technical interview a questioner asked me a weird question regarding to the execution of querysets. Suppose we have a profile model like below: class Profile(models.Model): user = models.OneToOneField('User').select_related(User) surname = models.TextField(null=True) q = Profile.object.all() or q = Profile.object.get(id=1) l = q.filter(active=True) he asked how many query execution has been happened and I replied as the python interpreter executes Profile.object.all() at the begging then one query is already done. However, he answered zero, and one if we call the query, something like this: for a in l: a.surname Is his answer true in django? another doubt was about models.OneToOneField('User'), why he didn't use django.contrib.auth.models.User and defined models.OneToOneField('User').select_related(User) -

How to redirect to an authenticated view with access token from another app in Django?
I have a Django website with two apps running on it. On app 1 the user receives an auth token and is supposed to be redirected to app 2 with said token. App 2 requires authentication in all views through APIView's permission_class "IsAuthenticated". app2/urls.py: app_name = 'app2' urlpatterns = [ path('',views.waitingroom_view.as_view(), name = 'waitingroom_index'), path('authenticated/',views.authentication_view.as_view(), name ='authentication') ] app2/views.py: class waitingroom_view(APIView): def get(self, request): return redirect('app1/index') My code correctly authenticates the user by giving them authentication tokens (refresh and access tokens) through a requests.post function: app1/views.py: def get_authentication_tokens(request, username, password): #BEWARE: hardcoded URL url = 'http://127.0.0.1:8000/api/token/' postdata = { 'username': username, 'password': password, } r = requests.post(url, data=postdata) tokens_json = r.json() #splits the respective tokens into 2 variables: "refresh" and "access" refresh_token = tokens_json['refresh'] access_token = tokens_json['access'] return access_token, refresh_token response = requests.get('http://0.0.0.0:8000/authenticated', auth=BearerAuth(access_token)) return HttpResponse(response) This returns a .html page that requires an auth token to access. However, the return is on app 1 instead of redirecting to app 2 with auth token. How do I redirect to an authenticated view (app 2) from another app (app 1) (that generated the auth token)? -

I have an application which connects to Instagram API and pulls massive amount of data everyday. My next challenge is to pull and save many Instagram users stories to a storage, then let my application users to see/view those stories in my django web app. I need to save nearly 50 GB of short videos (stories) everyday This makes nearly 20 TB of data for a year, so the storage must be at least that big The amount of stories that will be watched per day on my web app will be < 1000 (less than 1 GB) I don't have any experienced developers/engineers around me, so I do my own research about the subject. Azure Blog Storage looks like the solution that fit my needs but also a very expensive one (200-400$ per month). I have experience with Postgres and MySQL databases but not with Cloud services like Google or Azure, so any links, advices and tips are appreciated highly.
