Can't connect my django backend with Postgrsql
In my dockerized project, I'm trying to connect my Django app with Postgresql but it keeps giving me this error: File "/home/cr_user/.local/lib/python3.9/site-packages/psycopg2/__init__.py", line 122, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) django.db.utils.OperationalError: could not translate host name "db" to address: Temporary failure in name resolution My compose.yml version: '3.9' services: db: container_name: db image: postgres:13 ports: - '5432:5432' env_file: - ./server/.env volumes: - dbdata:/var/lib/postgresql/data/ networks: - cr_nginx_network cr_api: container_name: cr_api build: context: ./server dockerfile: Dockerfile command: python manage.py runserver 0.0.0.0:5000 ports: - "5000:5000" volumes: - ./server:/cr_server depends_on: - db volumes: dbdata: pgadmin_data: networks: cr_nginx_network: driver: bridge My settings.py DEBUG = True ALLOWED_HOSTS = ["*"] DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ.get("POSTGRES_NAME"), 'USER': os.environ.get("POSTGRES_USER"), 'PASSWORD': os.environ.get("POSTGRES_PASSWORD"), 'HOST': 'db', 'PORT': 5432 } } The postgres container is running without a problem but I can't see causing the issue. -
NoReverseMatch: Reverse for '<data>' with arguments <args> not found. 1 pattern(s) tried
Extremely new Django learner here. I am working on a personal project and got this error. views.py def download_video(request): ... return redirect(reverse('download_status', args=[True, None, str(name)])) def download_status(request, download_success, download_error=None, video_id=None): ... context = { 'download_success': download_success, 'download_error': download_error, 'new_filename': video_id, 'entries_page': paginated_subs, 'video_id': video_id } return render(request, 'download_status.html', context) Basically, it is a request from download_video method to redirect to another page that will display the subs list in a paginated manner. urls.py urlpatterns = [ path('download/', views.download_video, name='download_video'), path('data/<video_id>/', views.download_status, name='download_status'), ] download_status.html {% load static %} <!-- displayer.html --> ... pagination support code ...

How to solve this blog problems?
I made this blog which has some major problems I list them down below I appreciate it if you'd help me with either one you know the solution for if I need to add any other codes please let me know 1- when I login as different users and write a post it always mentions only one of my accounts as the author it doesn't write the current user's username as the author and I can see and delete all the other users posts when I login only one of the accounts 2-when I write a post the spaces between the lines and all that is correct but when I post it it all just displays beneath each other with no space 3- I cannot make this footer stretch to the width of the webpage and when I include it in my base.html it changes the styling of the other parts I think due to its CSS 4- when I go to my detail page the buttons on the navbar stretch down base.html {% load static %} <!DOCTYPE html> <html> <head> <title> {% block title %}{% endblock %} </title> <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script> … -
how to use google identity services with django-react
ive really read a hundreds outdated questions and blog posts but still cant seem to find a way. i tried using django-social-auth, django-all-auth and so much tutorials. on react im using https://www.npmjs.com/package/@react-oauth/google and i still dont understand alot of things: like does oauth2 work with the jwt token sent from google and from react. how am i supposed to get the data of a jwt token if it was signed by a google secret key that i dont know (or perhaps its the client secret?) and how am i supposed to have a password for user using a user model, unless a 3rd party packages helps with that -

The value disappears but still save in database
I have a registration form for a Python/Django project that uses Vue.js. I save the form correctly, but when trying to edit, I can see that the value is loaded properly, but it disappears very quickly, as if Vue.js/JavaScript is erasing it. When inspecting the field, I can see that its value receives the correct value from the registration, but the field becomes blank. <script> function capitalizeWords(string) { if (!string) return string; const words = string.split(' '); const capitalizedWords = words.map((word) => { if (word.length > 1) { return word.charAt(0).toUpperCase() + word.slice(1).toLowerCase(); } else { return word.toUpperCase(); } }); return capitalizedWords.join(' '); } var app = new Vue({ el: '#app', delimiters: ['[[', ']]'], data: { street: '', district: '', city: '', state: '', country: '', cnpj: '', name: '', trade_name: '', cnae: '', opening_date: '', selectedBank: '', bank: '', bank_code: '', nameInBankAccount: '', cnpjInBankAccount: '', postal_code: '', isLoading: false, isPostalCodeFound: true, isCNPJFound: true, display_form_address: false, display_form_bank: false, hasError: '{{ error }}' }, beforeMount: function () { this.street = this.$el.querySelector('#id_address-0-street').value this.district = this.$el.querySelector('#id_address-0-district').value this.city = this.$el.querySelector('#id_address-0-city').value this.state = this.$el.querySelector('#id_address-0-state').value this.country = this.$el.querySelector('#id_address-0-country').value this.cnpj = this.$el.querySelector('#id_company-cnpj').value this.name = this.$el.querySelector('#id_company-name').value this.trade_name = this.$el.querySelector('#id_company-trade_name').value this.cnae = this.$el.querySelector('#id_company-cnae').value this.opening_date = this.$el.querySelector('#id_company-opening_date').value this.getError(); }, watch: { … -
How can I add entries to my Model in Django, that are linked to a user using Firebase?
I am using React with FireBase to create users account on my Frontend. I am creating a table to track a users weight and it appears like this, from django.db import models from django.utils.translation import gettext_lazy as _ class Units(models.TextChoices): KILOGRAM = 'kg', _('Kilogram') POUND = 'lbs', _('Pound') class WeightTracking(models.Model): date = models.DateField() weight = models.IntegerField() units = models.CharField(choices=Units.choices, max_length=3) def _str_(self): return f'On {self.date}, you weighed {self.weight}{self.units}' The problem is, I have no idea how to track this to a user that is logged in. How can I add an entry that is linked to a user. FireBase gives me a UID for the user which I can send to the django backend, but doesn't Django have a default id column? How can I customize it or what is the best approach to linking an entry to a user for my future queries. Thanks! -
Django server does not accept cookies
When I try to send a POST request to the DJANGO app hosted on the server, with included credentials in the Axios request or with a Postman app, I cannot access cookies in the app, because cookies are never sent. Axios config looks like this: export function genericApiHost(host: string) { const headers = { "Content-Type": "application/json", Accept: "application/json", // "Access-Control-Allow-Origin": true, }; return axios.create({ baseURL: `${host}`, headers: headers, withCredentials: true, }); } If I include the allow origin header I get a CORS error, otherwise, cookies are not sent. This is part of the Django app settings: CORS_ALLOW_ALL_ORIGINS = True CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_SECURE = False CSRF_COOKIE_HTTPONLY = False CSRF_TRUSTED_ORIGINS = ['*'] ALLOWED_HOSTS = ["*"] With the settings I listed here, the application works correctly locally, but when the code is uploaded to the nginx server, it doesn't work -
Django - How to solve error "SIGPIPE: writing to closed pipe/socket/fd"
My web app sends out an email to users utilizing a standard format per django.core.mail.message.EmailMessage. It is received fine by most ISPs and browsers---but with one ISP, the emails are not being received by the users and these 2 related error messages are appearing on the PythonAnywhere server that I use: SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request [a specific URL in your web app] uwsgi_response_writev_headers_and_body_do(): Broken pipe [core/writer.c line 306] during [a specific URL in your web app] My research suggests it could be a server time-out issue related to nginx and uwsgi--but I don't think I have either installed; this is a wsgi application. My gut suggests it could be this specific ISP blocking my emails because I've been testing so much and it considers them spam. Is that plausible? Any thoughts on the likely cause of these errors or how I could resolve? -
Django primary key AutoField does not update when creating an object with explicit id
Suppose I have a model A in Django that uses the default primary key AutoField. Due to a transition process, I have created some objects of A with an explicit id, using A.objects.create(id=legacy_id). Coincidentally, these legacy ids start from 1. Then, when trying to create new objects without setting an explicit id, Django gives the error django.db.utils.IntegrityError: duplicate key value violates unique constraint "topics_reply_pkey" . It seems it is trying to create the object from id=1. If I added 20 objects with ids from 1 to 20, I expect that when using A.objects.create without an explicit pk, it would create the object with id 21. Why is this problem happening, and how can I solve it? -
Using DRF and django-tenants together in the same project
I'm currently building a multi tenancy app with django-tenants. However I also want to run my REST API in the same project as django-tenants. This is where the problem arises, if I were to make my API a shared tenants app every tenant subdomain ends up having their own API. For example, all registered tenants adopt the API routes as part of their subdomain: tenant1.example.com/api, tenant2.example.com/api, etc. I don't want my API to be underneath each tenant, I want to just run it on one domain, preferably api.example.com Does anyone have any advice on how to set this up? How are other people handling this in their projects? -
ManyToOne dropdown in Django admin inline
I have a Django project for keeping track of computers and parts. I have several different models set up for various types of parts, and they have a foreign key pointing to a model for a built computer. As it stands I can only assign a computer to a part, but I would like to do the opposite. Given something like the following: models.py class Computer(models.Model): pass class PartType1(models.Model): name = models.CharField(max_length=200) installed_in = models.ForeignKey(Computer, on_delete=models.SET_NULL, null=True) class PartType2(models.Model): name = models.CharField(max_length=200) installed_in = models.ForeignKey(Computer, on_delete=models.SET_NULL, null=True) I created some inlines hoping that would work: admin.py class PartType1Inline(admin.StackedInline): model = PartType1 class PartType2Inline(admin.StackedInline): model = PartType2 @admin.register(Computer) class ComputerAdmin(admin.ModelAdmin): inlines = (PartType1Inline, PartType2Inline, ) But this only allows me to create new parts from the Computer page. Because a computer can have an arbitrary number of a specific type of part (RAM modules as an example) I can't add the foreign keys to the Computer class. I've tried using OneToOne fields on the Computer class, but that requires adding a bunch of fields that usually end up going unused, and is not as flexible. What I would really like is a simple dropdown allowing me choose existing objects from PartType1, … -

GENERATED ALWAYS AS at MariaDB in Django
I have a column in mariadb called operator_tax_info, with the following structure, CREATE TABLE `operator_tax_info` ( `id` int(11) NOT NULL AUTO_INCREMENT, `created` datetime(6) NOT NULL, `modified` datetime(6) NOT NULL, `visible` tinyint(1) NOT NULL, `operator_id` int(11) DEFAULT NULL, `geolocation` point NOT NULL, `data` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NOT NULL CHECK (json_valid(`data`)), `fiscal_number` varchar(255) GENERATED ALWAYS AS (json_unquote(json_extract(`data`,'$.fiscal_number'))) STORED, PRIMARY KEY (`id`), KEY `operator_tax_info_operator_id_0c173d85_fk_companies_operator_id` (`operator_id`), SPATIAL KEY `operator_tax_info_geolocation_id` (`geolocation`), KEY `fiscal_number` (`fiscal_number`), CONSTRAINT `operator_tax_info_operator_id_0c173d85_fk_companies_operator_id` FOREIGN KEY (`operator_id`) REFERENCES `companies_operator` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=639 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci as you can see the column fiscal_number is a generated column from data column which is a json field, that column was recently added, to get fiscal_number from the json, and also as backend we use Django 3.2 as our ORM, with the following Model definition: class OperatorTaxInfo(BaseModel, SoftDeletionModel): operator = models.ForeignKey( 'companies.Operator', related_name='operator_tax_info_operator', on_delete=models.DO_NOTHING, null=True) data = JSONField(default=dict) geolocation = geomod.PointField('Geo_localizacion', default=Point(0, 0)) class Meta: db_table = 'operator_tax_info' So my question is there a way to map this column from mariadb to Django, or how to generate this column from Django using migrations and indexes, without losing speed from db, because I have trying using a @property decorator to map and annotate this … -

Facing an issue to update an existing object in Django 4
I'm working with a Diagnostic tool, I'm trying to update an existing instance of the database, I'm rendering a group of data corresponding to the device which being repaired, I have a second section of my render which shows a group of fields which must be updated by the Diagnosticador, those are the fields which will be updated.

Can't find the reason for this to turn the form into invalid.

Python-Streamlit Security
I'm using Streamlit for a web app. I built a system authenticator with streamlit_authenticator. When users log in, they can view specific data. I made a connection between Streamlit and MySQL.

For example, I tried with Django, but its difficult to integrate this with Streamlit. -
Django: My context variable with a zip list only works with one for loop. If I want to use the same variable in a different loop it doesn't work

How to define public permissions in the base class of django model and generate different codename for each subclass
django-4.2.6+python3.10 This is my base model class： from django.db import models class BaseModel(models.Model): class Meta: abstract = True permissions = [ ("restore", "Restore deleted obj"), ] This is my subclass： class One(BaseModel): name = models.CharField("name for you", max_length=200) class Two(BaseModel): name = models.CharField("name for you", max_length=200) After I executed python manage.py makemigrations and python manage.py migrate It generates such records in the auth_permission table of the database： auth_permission This is not what I want, because their codename is the same, which will lead to confusion. Because I have many such subclasses, all with the same type of permissions, but for different models, I don't want to repeat the definition in each subclass I hope that after running those two commands, it can generate different codename for each model in the database, such as： Generate a permission with the codename restore_one for the one model, and generate a permission with the codename restore_two for the two model. expected I tried to find the answer in the official documentation of django, but I got nothing. Perhaps we can start with the python manage.py makemigrations command. Can anyone tell me how to do it? -
Trouble Using Django Rest Framework 3.0 with Django 3.2 and Python 3.9
I am currently working on an assigmnet that requires working with specific versions of Django, DRF, and Python. Django Rest Framework (DRF) version >3.0 Django version >3.2 Python version >3.9 However, when attepting to use DRF version 3.0, I encountered the following error: django.template.library.InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'rest_framework.templatetags.rest_framework': No module named 'django.core.urlresolvers' I found that upgrading DRF to a version beyond 3.0 resolves this issue. However, the assignment specifically mandates using DRF 3.0. Could you please provide guidance or suggestions on how to address this error while ensuring compliance with DRF 3.0? Any help or insights would be greatly appreciated. Thank you!
