Django: oldest entry for distinct fields
I have the following models (simplified for sample purposes): class Execution(models.Model): name = models.CharField(null=False, max_length=30) creation_date = models.DateTimeField(auto_now_add=True, null=False) class Post(models.Model): class Meta: unique_together = ('code', 'secondary_code', 'execution') code = models.CharField(null=False, max_length=30) secondary_code = models.CharField(null=False, max_length=3) execution = models.ForeignKey(Execution, null=False, on_delete=models.CASCADE) text = models.TextField() On the database I have the following instances: execution_1 = Execution('Execution 1', '2019-01-01') execution_2 = Execution('Execution 2', '2019-01-02') post_1 = Post('123', '456', execution_1, 'lorem') post_2 = Post('789', '999', execution_1, 'ipsum') post_3 = Post('789', '999', execution_2, 'dolor') I want to retrieve all the posts, unique for code and secondary_code (so, only one between post_2 and post_3 since they have the same code and secondary_code) and chose the one to get based on the oldest execution (so, in this case, I want post_1 and post_2 since the execution of post_2 is older that the execution of post_3). I need to support both Postgres and sqlite3 3.18.0, so, because of sqlite, I cannot use window functions. How to do this? -
How to get the filepath while uploading a file to azure-storage in django
i have a form in which files can be uploaded.the uploaded file has to be stored in azure-storage. i am using create_blob_from_path to upload a file file to azure-storage.create_blob_from_path expects filepath as one of the parameter. but how can i get file path in this case as the operation has to be in on the fly mode(The uploaded file can not be stored in any local storage).it should get stored directly in azure. if request.method=="POST": pic=request.FILES['pic'] block_blob_service = BlockBlobService(account_name='samplestorage', account_key='5G+riEzTzLmm3MR832NEVjgYxaBKA4yur6Ob+A6s5Qrw==') container_name ='quickstart' block_blob_service.create_container(container_name) block_blob_service.set_container_acl(container_name, public_access=PublicAccess.Container) block_blob_service.create_blob_from_path(container_name, pic, full_path_to_file)//full_path_to_file=? the file uploaded dynamically has to be stored in azure -
Look up by primary key in graphene-django (with relay)
I'd like to be able to write a query that looks like this, using a human primary key rather than the opaque relay IDs: query { issue(pk: 10) { pk state } } I've been able to add the int pk field from the model; however, I haven't been able to figure out how to query it (and I'm a little confused about how I'd switch to a custom filterset for this). from django.db import models import graphene from graphene import relay class Issues(models.Model): state = models.CharField(default='') text = models.TextField(default='') class IssueNode(DjangoObjectType): pk = graphene.Int(source='pk') class Meta: model = Issue interfaces = (relay.Node,) filter_fields = ['pk', 'state'] class Query(graphene.ObjectType): issue = relay.Node.Field(IssueNode) issues = DjangoFilterConnectionField(IssueNode) This will raise an error about pk: TypeError: 'Meta.fields' contains fields that are not defined on this FilterSet: pk With this set up, I can write a query that looks like: query { issue(id: 'ascadf2e31af=') { state } } but since the application previously used human readable IDs, I'd like to support that as well. Any ideas on how to set up a custom filterset or if there's a native way to do this with graphene-django? -

Upgraded Django from 1.11 to 2.2. After cleaning up some obvious stuff as described in various upgrade checklists, got stuck on this one which does not seem to be answered anywhere.

How can I insert rows to DB in django from the code without forms
I opened a project in Jungo I worked closely with their training and when I got to the stage of posting rows to DB (after I created the modules that suited me) ,the way the guide suggested to me was to insert from the UI through the site itself - Or through PYTHON SHELL, The problem is that the data I need to enter into the site are not data that I am supposed to enter manually, I scraped it from another source, I have a Python file with a function that returns a list of objects that I need to insert into the DB When I tried various ways to combine the call to the above function in the ADMIN.PY file I encountered many errors and would be happy if you could direct how to do so -
Django-allauth initially creates a user- why?
I have just added django-allauth to our project. On launching the app I run no seeding, yet when i check the users there is a single user created: "AnonymousUser". from django.contrib.auth import get_user_model User = get_user_model() User.objects.all()[0].__dict__ { '_state': <django.db.models.base.ModelState object at 0x7fc0cb644c50>, 'id': 1, 'password': '!ckXY3T...wUhuko52q', 'last_login': None, 'is_superuser': False, 'username': 'AnonymousUser', 'first_name': '', 'last_name': '', 'email': '', 'is_staff': False, 'is_active': True, 'date_joined': datetime.datetime(2019, 5, 2, 8, 22, 32, 317584, tzinfo=<UTC>) } When using the django standard auth model no user was created by default. My settings and custom user model are below: # settings.py # Authentication AUTH_USER_MODEL = 'accounts.CustomUser' ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_AUTHENTICATION_METHOD = 'email' ACCOUNT_USER_MODEL_USERNAME_FIELD = 'username' ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_SIGNUP_PASSWORD_ENTER_TWICE = True ACCOUNT_SESSION_REMEMBER = True ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS = False ACCOUNT_EMAIL_VERIFICATION = 'mandatory' ACCOUNT_LOGOUT_ON_PASSWORD_CHANGE = True # accounts.models.py from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): def __str__(self): return self.email I can't find any documentation about this in the allauth docs, or by googling variations of "allauth AnonymousUser created". Why was a user created using allauth, and how can i disable this? -
JWT authentication in django 1.6
I am a newbie to django and I'm trying to implement JWT authentication. I have multiple micro-services, and I have a few questions. Right now what I am doing is- While logging into the first micro-service, adding the JWT token using request.session["Authorization"] = "Token " + my_token Is this the correct way of storing the JWT? I wrote a custom authentication class JWTBackend which implements authenticate method with signature that looks like: def authenticate(self, request): .... Then I added the path of this class to AUTHENTICATION_BACKENDS in settings.py. But django is not even entering my authenticate method. I know that usually authenticate methods have username and password as parameters, but mine has request. What should I change for my method to work? -

Checking the return value of a custom templatetag in a template
I have created a custom template tag which does some processing and returns 1, if all goes well,0 if not. In my template I want to check the returned value, and if it is 1, display an image. How should I go about doing this? The name of my function is fname which takes an argument n, and return a value of 1 or 0.

Authenticate through OTP sent to email of user
I want to send an OTP to the user's email Id. I checked I can send the eamil through the Django's send_eamil() method with random no. I am using the following to generate the random no. from django.utils.crypto import get_random_string otp = get_random_string(6, allowed_chars='0123456789') Now my question is how I can make it valid for a specific time in backend. Should I use session or cache or something else to store the otp. I have hardtime to figure out this. -

How to fix "Error Cannot read property 'hidden' of undefined" when trying to plot Chart.js from views.py
I'm trying to plot a graph from the database by using axios endpoint to get the data. I suspect it has something to do with the format. As I can see still see the correct data when navigating to api/chart/data/. I have two variables, one is working fine but another is undefined: total_km and sorted_vehicle_list so when I console.log(labels), it said "Error Cannot read property 'hidden' of undefined" P.S. sorted_vehicle_list has one only instance and returns as a list [] (which I'm sure if it's the problem) I have tried to print the output of the query in views.py and the output is correct. It returns the data that I want but somehow Chart.js can't see it. class ChartData(APIView): authentication_classes = [] permission_classes = [] def get(self, request, format=None): all_vehicles = LoggerRecord.objects.values('imei').distinct() vehicle_list = [] for vehicle in all_vehicles: vehicle_list.append(vehicle['imei']) sorted_vehicle_list = sorted(vehicle_list) #create sum km total_km = LoggerRecord.objects.aggregate(Sum('distance')) print(total_km) print(all_vehicles) data = { 'all_vehicles': all_vehicles, 'total_km': total_km } return Response(data) axios.get(endpoint) .then(function (response) { labels = response.data.sorted_vehicle_list total_km = response.data.total_km console.log(labels) console.log(total_km) var ctx = document.getElementById('myChart').getContext('2d'); var chart = new Chart(ctx2, { // The type of chart we want to create type: 'bar', // The data for our dataset … -

HSTS headers for Django + Nginx projects - should the headers be set by Django SecurityMiddleware or Nginx?
HSTS = HTTP Strict Transport Security From the Django Docs on HSTS For sites that should only be accessed over HTTPS, you can instruct modern browsers to refuse to connect to your domain name via an insecure connection (for a given period of time) by setting the “Strict-Transport-Security” header. This reduces your exposure to some SSL-stripping man-in-the-middle (MITM) attacks. SecurityMiddleware will set this header for you on all HTTPS responses if you set the SECURE_HSTS_SECONDS setting to a non-zero integer value. However this header can also be set by Nginx in the conf file, by adding a line: add_header Strict-Transport-Security "max-age=63072000; includeSubdomains;"; So the question is, should we configure Nginx to set this header or Django SecurityMiddleware, by adding the HSTS settings in the project settings file? -

Thumbnail generation failed
I'm currently using versatile image to generate thumbnails, but it throws many of the same errors relating to the fact that a thumbnail couldn't be generated even when the model instance that is being created doesn't require one.
