How do i get the uploaded file from the dropzone hidden input and send it to the socket?
I have a chatting application. I downloaded its template online (HTML, CSS, JS) and It uses Dropzone for file uploads, but I’m having a problem retrieving the file. When I upload the file, it creates a hidden input and previews it. but, when I unhide the input, no file is selected. I’m not sure if I should edit its JS file, but I don’t understand it since I barely know JavaScript. I just want to get the file and send it to my Django consumer. I don’t have any ideas on what to do // Messenger.js function toggleGroupConversation(group_id) { const conversationThread = document.getElementById('group-conversation-thread-' + group_id); const wsProtocol = window.location.protocol === "https:" ? "wss://" : "ws://"; const wsURL = wsProtocol + window.location.host + '/' + 'ws/messenger/group/' + group_id + '/'; offcanvasElements.forEach(element => { element.style.visibility = 'hidden'; element.classList.remove('show'); }); groupThreads.forEach(thread => { thread.classList.add('d-none'); }); conversationThreads.forEach(thread => { thread.classList.add('d-none'); }); if (conversationThread) { conversationThread.classList.remove('d-none'); } if (chatSocket !== null && chatSocket.readyState !== WebSocket.CLOSED) { chatSocket.close(); } chatSocket = new WebSocket(wsURL); chatSocket.onopen = function (e) { console.log('WebSocket connection established.'); }; chatSocket.onmessage = function (e) { const data = JSON.parse(e.data); const senderId = conversationThread.dataset.senderId; if (data.action === 'send_message') { let MessageContainer = conversationThread.querySelector('.py-6.py-lg-12'); let chatEmpty … -
configuring django with apache2
I have been working on my first django, which is a portfolio website. The site was working as intended when running on the django server, however when configuring it with apache on the linux server I few things have stopped working. I think it is is the way I have configure default.conf. this inculdes a button for downloading a rtf files and the CSS styling for the admin pages has not loaded. I have duplicated the 000-default.conf and called it django_project.conf and disabled the former and enabled the later. this is whats in that file: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/html ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /static /home/bashaar/rp-portfolio/static <Directory /home/bashaar/rp-portfolio/static> Require all granted </Directory> Alias /uploads /home/bashaar/rp-portfolio/uploads <Directory /home/bashaar/rp-portfolio/uploads> Require all granted </Directory> <Directory /home/bashaar/rp-portfolio/personal_portfolio> <Files wsgi.py> Require all granted </Files> </Directory> WSGIScriptAlias / /home/bashaar/rp-portfolio/personal_portfolio/wsgi.py WSGIDaemonProcess django_app python-path=/home/bashaar/rp-portfolio python-home=/homebashaar/. rp-portfolio/venv WSGIProcessGroup django_app I have also given apaches permission to these files: bashaar@portfolio:~$ ls -la total 52 drwxr-xr-x 6 bashaar bashaar 4096 Apr 23 10:19 . drwxr-xr-x 3 root root 4096 Apr 16 14:42 .. -rw------- 1 bashaar bashaar 9669 Apr 24 09:00 .bash_history -rw-r--r-- 1 bashaar bashaar 220 Apr 16 14:42 .bash_logout -rw-r--r-- 1 bashaar bashaar 3771 Apr 16 … -
Build a pre-decorated class with override_settings for faster client.login?
This makes a Django test using the test client run very much faster, where login security is not an important part of the test from django.test import TestCase, Client, override_settings @override_settings( PASSWORD_HASHERS = [ "django.contrib.auth.hashers.MD5PasswordHasher" ]) class Test2(TestCase): ...

For Django, 'sql_server.pyodbc' isn't an available database backend or couldn't be imported
I'm new to Django and trying to set up a DB Connection with SQL server db. Earlier we had mysql which was working fine, I'm having trouble connecting to sql server DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'AAAAA', 'USER': 'AAAAA', 'PASSWORD': 'AAAAA', 'HOST': 'AAAAA', 'PORT': '1433', } } Error: django.core.exceptions.ImproperlyConfigured: 'sql_server.pyodbc' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of: 'mysql', 'oracle', 'postgresql', 'sqlite3' Tried https://learn.microsoft.com/en-us/sql/connect/odbc/linux-mac/install-microsoft-odbc-driver-sql-server-macos?view=sql-server-ver16 doesn't work. Also, I have 2 question Is it a good idea to use third party library/drivers for SQL server? will it affect the performance compared to Mysql? -

Django: how to store email credentials when sending email from a Django application
What is a standard or safe way to store my Google Workspace email credentials in my first Django project? I've tried to store the password in an .env file, but I get all kinds of error messages (e.g., "decouple module not recognized"--despite my alternately using pip install decouple and pip install python-decouple). But more importantly, I suspect it's not the best approach anyway. My research seems to whittle the options down to eliminating my password altogether and to somehow API into Google from within my app (to send out emails to my customers from my Google Workspace email). Is that would you recommend? Is there an simpler/better way? -

Operating AI program by using WebODM plugin
I created an AI Python program and made the program screen visible through a plug-in. I try to run a program written in Python on that screen, but it doesn't work. How do I get it to run? To run an AI program, you must run Anaconda 3, run a virtual environment inside it (if it does not exist, create it and run it), and run it after completing the installation of the required programs. These must be included in the implementation process. I added new url ''' url(r'^airesults/$', app_views.aiwork, name='results') ''' in \WebODM\app\urls.py and create new function 'aiwork' in \WebODM\app\views\app.py and make new coreplugin 'aiwork' by copying and modifying the 'cloudimport'. -
How can I use stored procedures in Django with MySQL and run 'python manage.py migrate' without issues?
Context: I'm working on a project using Django with the Django REST framework to build an API. My database is MySQL, and I'm using XAMPP as my local development environment. Problem: I need to use stored procedures in my Django application to perform specific operations in my MySQL database. However, I'm facing difficulties integrating the stored procedures with Django, and I'm also experiencing issues when running python manage.py migrate. Additional Details: I have created stored procedures directly in my MySQL database using phpMyAdmin. I'm using Django's ORM to interact with the database in other parts of my application. I would like to be able to call the stored procedures from my Django application and run python manage.py migrate without errors to ensure that my database is properly synchronized with Django's models. Relevant Files and Code: utils.py - File containing the calls to the stored procedures. models.py - File where I define Django models representing my database schema. Questions: What is the best way to use stored procedures in Django, particularly with a MySQL database? How can I ensure that the stored procedures are compatible with Django's migration process (python manage.py migrate)? Are there any special considerations I should be aware … -

Persistent storage in a Python app hosted in Heroku
I have an app that I recently deployed to Heroku. I wrote the app in Python utilizing the Django framework. When I create user accounts via my admin dashboard in the app I see the user accounts after being created. After a while has passed, I check and the new user accounts I created has disappeared. My thoughts are that this is down to allocated resources/dynos and everything is stored only for a session and once the session ends all changes are reverted to the state the app was in when first uploaded. The database is SQLite. I am trying to determine how I can have new users stay in the database or how other apps hosted on the platform (Heroku) allow user registration without the user accounts disappearing after a session ends. I have searched and read documentation on Heroku, Googled the problem and found nothing that matches my situation. One issue I read about mentioned an issue uploading static files that would disappear after sessions ended and how integrating 3rd party storage could resolve that. I understand that solution, but for user creation and registration, this would not be feasible. Thanks in advance! -
Django default connections.cursor() not parsing JSONB into DICT despite using PSYCOPG3
I am switching an old codebase from Django ~2 to Django 4.2.1. Along side this switch, I upgraded psycopg2 to psycopg (also known as psycopg3), but this switch has caused my cursor to incorrectly fetch rows from my PostgreSQL database. I am receiving STR instead of DICT when selecting JSONB objects in my database Important: When I use psycopg.connect directly, all of the behavior returns to what I expected. It is only when I am using the default django connection. from django.db import connection Here I fetch some json objects and check the type. with connection.cursor() as cursor: cursor.execute("select json_file from json_file") # These are of type jsonb for row in cursor.fetchall(): type(row[1]) This usually returns dict but is now returning str Here is my DATABASES variable in settings: 'default': {'NAME': 'postgres', 'USER': 'postgres', 'PASSWORD': 'postgres', 'HOST': 'db', 'PORT': 5432, 'CONN_MAX_AGE': None, 'CONN_HEALTH_CHECKS': False, 'ENGINE': 'django.db.backends.postgresql', } Here is Django's Connection + Cursor > connections['default'].connection <psycopg.Connection [IDLE] (host=db database=postgres) at 0x...> > connections['default'].connection.cursor() <django.db.backends.postgresql.base.Cursor [no result] [IDLE] (host=db database=postgres) at 0x...> Here is psycopg's Connection + Xursor > psycopg.connect("...") <psycopg.Connection [IDLE] (host=db database=postgres) at 0x...> > psycopg.connect("...").cursor() <psycopg.Cursor [no result] [IDLE] (host=db database=postgres) at 0x...> -

The problem of not generic refresh and access token for users
I have a problem with the code written with Python and Django framework I wrote a custom model and used Abstrcatuser in it, and instead of the username field, I used the phone number field. Now, when I enter the login address in the api I wrote and want to get the access token and refresh token, it creates only these things for the superuser and tells the other users that the phone number or password is wrong if they are also correct. I also use jwt. I tried to make some changes in the code, but I didn't find anything important -
