Django Rest Auth and Google Auth - Google does not store username and email
Currently I have a registration with Django Rest Auth where I implement a login with Google under an extended user model with AbstractUser, the problem is that when authenticating with Google, when the user registers it does not store the username and email of the email I entered With google. Any ideas? This is the AbstractUser model: class User(AbstractUser): full_name = CharField(_("Full Name"), max_length=255, null=True, blank=True) device_token = models.CharField(_("Device Token"), max_length=200, null=True, blank=True) cellphone = CharField(_("CellPhone"), max_length=15, null=True, blank=True) class Meta: verbose_name = "User" verbose_name_plural = "Users" def get_absolute_url(self): return reverse("users:detail", kwargs={"username": self.username}) This is the example of a user who has logged in with Google, this is how the model looks in the database: Model User with Google Request with token user Whats is the problem? I hope that google stores the email and user at the time of registering in the Django database. -
Why I can't install django offline?
I have to install django on a company server that does not have Internet access. After downloading and installing ***pytz-2023.3.post1-py2.py3-none-any.whl*** I am able to install ***django*** from the .zip file. You might ask what's the point if I'm able to install it? Well, I can install django and the necessary libraries from the downloaded files only when the server is connected to the Internet. It turned out that the following libraries are necessary during installation: - asgiref-3.7.2-py3-none-any.whl - tzdata-2023.3-py2.py3-none-any.whl - sqlparse-0.4.4-py3-none-any.whl Of course, I downloaded and installed them without any problems. However, I still get an error when installing django. Below is the error code. C:\Users\Administrator\Downloads>py -m pip install django-stable-4.2.x.zip Processing c:\users\administrator\downloads\django-stable-4.2.x.zip Installing build dependencies ... error error: subprocess-exited-with-error × pip subprocess to install build dependencies did not run successfully. │ exit code: 1 ╰─> [7 lines of output] WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x00000221F9E73C10>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed')': /simple/setuptools/ WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x00000221F9E7B4D0>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed')': /simple/setuptools/ WARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection … -
How do I implement a button that navigates to the next question in Django if one question is displayed on a page?
Code and some explanations on how to do it in Django for a beginner.

Displaying the sum of expenses in my dashboard page
Hello guys so I have an expense app that helps to keep track of all expenses in a project but I want to display the sum of all these expenses on the dashboard page so that when the user logs in they can see the total expenses of a particular project. I already have a html file (expenses.html) which shows a table of all expenses (but not the sum) so I was thinking maybe there is a way I can calculate the sum and incorporate it in the dashboard page. So here is how I tried doing it with no success; I created a model in my models.py (of the dashboard) class Expense(models.Model): amount = models.FloatField() Then went to my view.py (of the dashboard) to define a function called total_expenses. def total_expenses(request): total_expenses = Expense.objects.aggregate(total=Sum('amount')) return {'total_expenses': total_expenses['total']} After that I returned to the dashboard.html and wrote this; <div class="card mt-3"> <a class="nav-link" href="{% url 'expenses' %}"> <h5 class="card-category">Total Expenses</h5> <h2 class="card-title"> ({{ total_expenses }}) </h2> </a> </div> I want the sum to be displayed in the brackets as shown in the image provided; Tab to display the sum I know it is not a lot but I would appreciate … -
Python 3.11 - IIS 10 - AttributeError: Module has no attribute 'wsgi'
I have a Python (3.11) web application using Django 4.2.5 deployed to a Windows 2019 Server running IIS 10. I have deployed several Python + Django apps to IIS WebServers previously with no issues, however they were older versions (Windows 2016, python 3.8, django 3.2) I don't expect that much has changed since then so when deploying this application I mimicked the configuration of IIS, however it continues to give me the same error. I have all of the Windows Features installed (IIS, CGI, .Net 3.5 and 4, etc) I have configured the Environment Variables in the FastCGI settings (IIS WebServer level), and the Application Settings (on the site level) I have configured the Handler Mappings And yet no success.

Django managed=False model save doing insert instead of update and failing for duplicate PK
I'm connected to a legacy database using PyODBC. Some models insert and update just fine, however this one doesn't. When we grab existing records using the ORM, it tries to do an insert on save instead of an update class PurchaseOrder(models.Model): purchaseorderid = models.BigAutoField(db_column='PurchaseOrderId', primary_key=True) ticketnumber = models.CharField(db_column='TicketNumber', unique=True, max_length=20, blank=True, null=True) customer = models.ForeignKey('Customer', to_field='local_id', db_column='CustId', on_delete=models.DO_NOTHING) # a bunch of other irrelevant columns class Meta: managed = False db_table = 'PurchaseOrders' In the shell (or code anywhere else) I can grab an existing PurchaseOrder and even print it's pk just fine: >>> po = PurchaseOrder.objects.all()[76543] # grab a random existing po >>> print(po.pk) 78730 But when I go to save the record, which should do an update -- we've verified the pk exists -- it tries to do an insert and fails due to duplicate pk: >>> po.save() Traceback (most recent call last): File "/home/django/.env/lib/python3.10/site-packages/django/db/backends/utils.py", line 89, in _execute return self.cursor.execute(sql, params) File "/home/django/.env/lib/python3.10/site-packages/mssql/base.py", line 621, in execute return self.cursor.execute(sql, params) pyodbc.IntegrityError: ('23000', "[23000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Violation of PRIMARY KEY constraint 'PK_PurchaseOrders_1'.

Docker + Django + ElasticSearch: Failed to establish a connection
I'm having issues connecting ElasticSearch to Django while dockerizing my application. When I try to run my applicatiom using docker compose, i get the following error: elastic_transport.ConnectionError: Connection error caused by: ConnectionError(Connection error caused by: NewConnectionError(<urllib3.connection.HTTPSConnection object at 0x7fc59132e890>: Failed to establish a new connection: [Errno 111] Connection refused)) Before building the containers, I followed this tutorial, adapting the packages to the versions I wanted. I was able to establish a connection between the Django App and a single-node cluster running on a docker container. I copied the SSL certificate from the ElasticSearch container to the Django app root, and defined the ELASTICSEARCH_DSL on Django settings as: ELASTICSEARCH_DSL = { 'default': { 'hosts': ['https://localhost:9200'], 'http_auth': ('elastic', 'password'), 'verify_certs': True, 'ca_certs' : './http_ca.crt', }, } After building the containers and creating a docker-compose.yml, I didn't find a way to extract the certificate to the Django container. I tried to establish a connection putting 'verify_certs': False but it didn't work. I tried to find a solution, but most of the time I found people using ElastiSsearch 7.x.x while I'm using version 8.10.1.

Django: adding a second 'detailed' view for retrieving extra information
I have set up my urls.py and views.py file to serialize my Projects model in two different ways: detailed information for the 'retrieve' action, and abbreviated information for the 'list' action. This works well so far: /projects/ = list of projects with abbreviated information /projects/12 = detailed information about a specific project (id=12) urls.py: router.register(r'projects', ProjectViewSet, basename='project') views.py class ProjectViewSet(viewsets.ModelViewSet): serializer_class = ProjectSerializerMini # Select a serializer according to the action (i.e.: 'retrieve' will # return a more detailed serialized data than 'list') action_serializers = { 'retrieve': ProjectSerializerDetail, 'list': ProjectSerializerList } def get_serializer_class(self): return self.action_serializers.get(self.action, self.serializer_class) My question is: would it be possible, using the ViewSet framework, to summon a third serializer that would return, say, an even more detailed set of information. Ex.: /projects/12/extradetail The reason for this is that some of these records include geospatial data that is quite voluminous. I would only want to retrieve this extra detail in some cases -
django-simple-history only works in the admin interface
I am trying to get django-simple-history to work. It does work in the admin interface but not in my view code. I recreated the sample but it does not work for me.

If u change it in the admin interface i do get a changed entry. Does anyone know what i am doing wrong. Using: Django==4.2.6 django-simple-history==3.4.0 -

django rest serializer to_representation failing
Im messing around with django rest framework and its serializers, and im running into an error when overriding the create method. serializer class AdddTestModel(serializers.Serializer): name = serializers.CharField() score = serializers.FloatField() score2 = serializers.FloatField() song = serializers.IntegerField() def create(self, validated_data): print(validated_data["song"]) song = Song.objects.get(id=validated_data["song"]) print(song) instance = TestModel.objects.create(name=validated_data["name"], score = validated_data["score"], score2 = validated_data["score2"], song = song) return instance def to_representation(self, instance): representation = super().to_representation(instance) return representation View @api_view(["POST"]) def addTestModel(request): serializer = AdddTestModel(data=request.data) if serializer.is_valid(): serializer.save() print(serializer.data) return Response("hello", status=status.HTTP_201_CREATED) return Response("Error", status=status.HTTP_401_UNAUTHORIZED) I had everything working correctly when I was using a modelSerializer, but wanted to experiment with serializer.Serializer. I know the create method is working as the TestModel object is being persisted into my db. The error seems to be coming from the to_representation method, specifically representation = super().to_representation(instance) The error i am getting is the following Internal Server Error: /api/addTest/ Traceback (most recent call last): File "C:\Users\thoma\Documents\venv\lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) File "C:\Users\thoma\Documents\venv\lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\thoma\Documents\venv\lib\site-packages\django\views\decorators\csrf.py", line 56, in wrapper_view return view_func(*args, **kwargs) File "C:\Users\thoma\Documents\venv\lib\site-packages\django\views\generic\base.py", line 104, in view return self.dispatch(request, *args, **kwargs) File "C:\Users\thoma\Documents\venv\lib\site-packages\rest_framework\views.py", line 509, in dispatch response = self.handle_exception(exc) File "C:\Users\thoma\Documents\venv\lib\site-packages\rest_framework\views.py", line 469, … -
How to update Model attributes in production
I have a django app which I deployed three years ago that has been working perfectly and making our life in the laboratory easier. Recently there was a need that wasn't contemplated in the beginning, and I have added some functionality to the app. This involved modifying some Model methods and some AdminModel methods as well. Unfortunately web development is not my field and this was a single thing that I did with Python in my spare time and now I'm not sure what will happen If I pull the changes from the repository. I remember that in development I had to use manage.py migrate manage.py makemigrations after any changes to the models attributes. In this case it's only methods that I have modified. Do I still need to run these commands in the production server? Will I loose data (this can not be tolerated)? I'm using the sqlite standard database that django generates by default. Thanks a lot in advance. -
React Items wont render using Router
I am using routes in a react/django app and I have components that will not render. This is my app.js which renders my homepage. import React, { Component } from "react"; import { render } from "react-dom"; import HomePage from "./Homepage"; export default class App extends Component { constructor(props) { super(props); } render() { console.log("App Here"); return ( <HomePage /> ); } } const appDiv = document.getElementById("app"); render(<App />, appDiv); This is my homepage.js: import React, { Component } from "react"; import RoomJoinPage from "./RoomJoinPage"; import { Routes, Route, BrowserRouter } from "react-router-dom"; export default class HomePage extends Component { constructor(props) { super(props); } render() { console.log("homePage Here") return ( <BrowserRouter> <Routes> <Route path="/" element={<p>Test</p>} /> <Route path="/join" element={<RoomJoinPage />} /> </Routes> </BrowserRouter> ); } } And this is a component I am trying to render: import React from "react"; export default function RoomJoinPage() { console.log("RoomJoinPage component is rendering."); return <h1>Room Join Page</h1>; } I have it working with HTML, and have narrowed it down to the routing issue. Any insight would be helpful. Thanks! I have tried various different routing configurations. My versions are: "react": "^18.2.0", "react-router-dom": "^6.17.0". I would like the components to render on the correct routing. -

How to search multiple fields using objects.filter

Trade-offs and considerations for conditional tuple unpacking in Python: primarily performance but also stylistic considerations for maintainability
I have a piece of logic in Python that involves tuple unpacking based on conditions. The code instantiates two variables, and assigns to these variables the unpacked values of a tuple. This tuple is defined conditionally: if a conditional_expression is true, then a function executes returning a tuple, else default values are provided and assigned. My understanding is there are two simple ways to implement this, as follows: # Method 1 # if conditional_expression: processed_data, context = tuple_returner(raw_data) else: processed_data, context = raw_data[0], None # Method 2 # processed_data, context = ( tuple_returner(raw_data) if conditional_expression else raw_data[0], None ) Now I have tried both ways, and both work well as expected. My question is two-fold: Is either method likely to be more performant than the other (in a standard CPython implementation)? I do not notice any substantial differences when running timeit tests (although method 2 seems ever so slightly faster), but I was wondering if anything deeper is happening under-the-hood that I'm not aware about. Is either method more Pythonic and generally preferred by the community than the other? I couldn't see anything specific inside PEP8 to guide me on this. Both seem readable to me but this code-base will … -

How to upadate a text for H2 tag from views.py in django

python django factory set random locale and then create model based on this locale
I would like to create test models of people of different nationalities. During creation, factory would randomly select nationality from a list of "locale" attributes. It would then determine personal attributes based on the previously drawn nationality. Here is my code, which does not work. It mixes attributes of different nationalities class PersonModelFactory(factory.django.DjangoModelFactory): locale = factory.fuzzy.FuzzyChoice(["cs_CZ", "da_DK", "de_DE", "en_GB", "es_ES", "fr_FR", "hr_HR", "hu_HU", "it_IT", "nl_NL", "no_NO", "pt_BR", "pt_PT", "ro_RO", "sk_SK", "fr_CH", "pl_PL", "de_AT", "es_AR"]) class Meta: model = Person exclude = ("locale",) first_name = factory.Faker("first_name_male", locale=locale) last_name = factory.Faker("last_name_male", locale=locale) nationality = factory.Faker("current_country", locale=locale) ...and so on... In addition, it would be best if half of the people could be British, another half as other mixed nationalities. I tried this code to do so: locale = factory.fuzzy.FuzzyChoice(["en_GB", None]) if locale is None: locale = factory.fuzzy.FuzzyChoice([...]) Unfortunately, only the first line of code is is read and the program only chooses between en_GB and None (which is en_US by default). If statement is ignored. -

Errno 13 Permission denied: 'images' on Production environment
I'm facing an issue with file permissions when trying to access an AWS S3 bucket in my Django application. Everything works perfectly in my local development environment. However, when I deploy the application to my production environment, I encounter a "Permission Denied" error when trying to read/write from the 'images' directory in the S3 bucket. Locally, I see successful GET and POST requests in my logs, and the S3 URLs are generated as expected. In production, I get an error message saying "Exception in generate_diamond_painting_preview: [Errno 13] Permission denied: 'images'." I've checked my IAM policies and S3 bucket policies, and they seem to allow for the necessary actions. I'm at a loss for what could be causing this discrepancy between my local and production environments. Local Environment Testing: Verified that the S3 bucket interaction works as expected in my local development environment. Files are read and written without any issues. AWS IAM Policy: Reviewed the IAM policy attached to the role/user used by the Django application. The policy allows for full S3 access to the specific bucket and its contents (s3:*). Server Logs: Checked the logs in the production environment to pinpoint the error, which led me to the "Permission … -

Django Admin: IntegrityError When Adding New or Modifying Existing Models From Django Admin Panel in Browser
I'm encountering a peculiar issue when attempting to add or update existing models through the Django Admin panel.

However, it's worth noting that when I update or add new data using my custom admin interface, everything works as expected. I'm seeking assistance in understanding the root cause of this issue and how to resolve it. Any guidance would be greatly appreciated. -
Htmx POST for Editable Row
