Difficulty Establishing Secure Connection Between Web Server and MQTT Server
I'm currently working on a project for monitoring robots, and I've developed a web platform using Django and Vue for data acquisition and visualization. At present, I'm utilizing an MQTT server to transmit all my data. However, I've encountered an issue while trying to configure communication between my web page, which has an SSL certificate generated by Certbot, and the MQTT server implemented on a Raspberry Pi 4. I've attempted to generate an SSL certificate for MQTT using OpenSSL, but I've been unsuccessful in establishing a connection between the web server and the MQTT server. It seems that the web page doesn't allow unencrypted connections with the MQTT server. I'm employing the WebSocket protocol for this connection. Additionally, I'm unable to use Certbot to generate an SSL certificate for the Raspberry Pi, as I don't have my own domain for the Raspberry Pi's IP address. Does anyone have any ideas about what might be happening or any alternative methods for securely establishing this connection? Thanks in advance for your assistance. When attempting to establish the connection between my web server and the MQTT server, I used an SSL certificate generated by Certbot on the web server and tried to generate … -
What's an easy and safe way to provide users access to MySQL database so they can interact with it (CRUD)?
I'm creating a database for a small community and would like to set up a web interface for them to interact with it. I'd like users to be able to use a password to access their own records for changes. Also I assume there's a way to assign users to groups to be able to access a wider set of rows. Someone mentioned Django and I see that there are other possibilities like PHP. I have database experience, but little experience with web pages. I don't have much javascript or CSS. I haven't tried anything yet. I'm still considering how to start. -

Django REST Framework login and logout views
I'm building a system using django, django rest framework, django oauth toolkit, django axes in a microservices architecture but I have some doubts. Currently I have my "login" view on the client that takes the username and password from the POST request and sends it to my "UserLoginAPI" API, in the "UserLoginApi" view I validate the user and password in the "UserLoginSerializer" serializer, I check if the user is not blocked in django axes and I create a token for this user with oauth, the serializer returns the authenticated user and the token and "UserLoginApi" updates the last_login with update_last_login, I saw in a discussion on stackoverflow that it should be used update_last_login instead of login(request, user), then I return the token back to the "login" view on the client, and on the client I take this token and store it in the session and with middleware I check in each request if the token exists and if the token exists, if it has already expired, if it exists and has not expired, I update the session user with the user associated with the token. And at logout I do the same thing but I use logout(request) to log out … -

Null value set to True, but still it violates not-null constraint
I am trying to set a null sidebar from the Django admin interface as shown below: However, when I press "Save" I get an IntegrityError error: IntegrityError at /admin/qa/howquestion/112/change/ null value in column "sidebar_id" violates not-null constraint DETAIL: Failing row contains (112, <p>prettyprint a JSON file<br></p>, To pretty print a JSON file in Python, you can use the json m...).

How do I save the pasword as hashed password in postgressql database
I have created a custom user model Employee in Django that extends AbstractBaseUser. The Employee model has a password field of type CharField. I am using PostgreSQL as the database.

Instead, it is being stored as plaintext.

Blacklisting Network Range on django-blacklist
I've noticed recently that my django-website is being crawled by a number of spammy bots, so while looking for a way to block this IP-range I came across django-blacklist. It works well for the most part, and I've successfully blocked single IPs, but when I tried to block a range (51.222.253.0 - 51.222.253.255), it seems to be unsuccessful. My inputs were: Address = 51.222.253.0 & Prefixlen = 24 (see image below). I've read the docs, and can't seem to get more clarity on this topic, however, this isn't a strong suit of mine so let me know if I've done something wrong. All help is appreciated! -

Django Adding Square Brackets In Admin-Related Views
I am hosting two Django applications on a webserver and I recently upgraded all my packages to more recent versions, along with bringing the project to Python 3.12, which was generally beneficial. In doing so, I noticed that square brackets ("[]") started appearing in seemingly random views associated with admin views. To be specific, when looking at individual models in the admin view AND on the sign-in page, which I believe Django admin heavily handles. It's not mission critical to solve, and there's nothing in the source code that I know of that would cause this, and no code changes were made apart from upgrading versions. I would think it's some random setting I have to turn off but I've spent a good amount of time trying to figure it out.

How to configure Apache to deploy a project with Django and React?
After testing on localhost and checking that the application works, I want to deploy it from Apache (xampp). I am using Windows Server 2016 operating system, Python 3.11.8. I have also downloaded the file mod_wsgi-4.9.2-cp311-cp311-win_amd64.whl I have tried to modify the Apache configuration (httpd.conf), adding a virtualhost (80) for the frontend and it worked correctly. The problem occurs when I want to add another virtual host (8000) for Django, causing Apache to fail to start: <VirtualHost *:80> ServerName fichaje.local DocumentRoot "C:/Users/Administrador/Documents/fichaje/frontend/build" <Directory "C:/Users/Administrador/Documents/fichaje/frontend/build"> Options Indexes FollowSymLinks AllowOverride All Require all granted LoadFile "C:/Users/Administrador/AppData/Local/Programs/Python/Python311/python311.dll" WSGIPythonHome "C:/Users/Administrador/AppData/Local/Programs/Python/Python311" LoadModule wsgi_module "C:/Users/Administrador/AppData/Local/Programs/Python/Python311/Lib/site-packages/mod_wsgi/server/mod_wsgi.cp311-win_amd64.pyd" <VirtualHost *:8000> ServerName fichaje_back.local Alias /static "C:/Users/Administrador/Documents/fichaje/static" <Directory "C:/Users/Administrador/Documents/fichaje/static"> Require all granted <Directory "C:/Users/Administrador/Documents/fichaje/fichaje"> <Files wsgi.py> Require all granted </Files> </Directory> # Script WSGI WSGIDaemonProcess fichaje python-path=C:/Users/Administrador/Documents/fichaje;C:/Users/Administrador/Documents/fichaje/myenv/Lib/site-packages <IfModule mod_wsgi.c> WSGIPythonHome "C:/Users/Administrador/AppData/Local/Programs/Python/Python311" </IfModule> -

How can change the primary key in a django model so that other dependent models are also affected and the changes are synced to the postgresql db
I have a django project with a database table that already contains data. The models: class Foo_A(models.Model): field1_pk = models.CharField(max_length=50) field2 . . fieldN_newpk = model.CharField(max_length=50) Data in field1_pk and fieldN_newpk are exactly the same. Lets say I have other models that reference fieldN_newpk as foreign key. I would like to rename a fieldN_newpk in this Foo_A model, without losing any data. This change should also be reflected in my other dependent models. I want to change the primary key from field1_pk to fieldN_newpk I want these changes to be reflected in my postgresql database as well I have seen other answers related to renaming of a model Also Is there a safe way/safe mode to try out these changes/migrations before actually trying on the original codebase -
Synchronizing a Django database with a Realm or Core database in an iOS app
I'm working on an iOS app that needs to synchronize data with a Django backend. The backend uses Django ORM and exposes data through a RESTful API built with Django REST Framework. On the iOS side, I'm using Realm or Core in future as the local database. I need guidance on how to implement synchronization between the Django database and the Realm or Core database in my iOS app. Specifically, I'm looking for advice on the following: How to design the synchronization process to ensure data consistency and integrity. Strategies for fetching data from the Django API and storing it locally in the Realm database. Techniques for handling conflicts between local and server data. Best practices for optimizing synchronization performance and reliability. Recommendations for error handling and retry mechanisms in case of network failures or server errors. Any security considerations or precautions I should take when implementing data synchronization. I would appreciate any insights, sample code, or references to relevant resources that can help me implement robust and efficient data synchronization between my Django backend and iOS app using Realm. Thank you! Some advices who work with
