download file from url in django
I want to download a file from a URL. Actually, I want to get the file from a URL and return it when the user requests to get that file for download. I am using this codes: def download(request): file = 'example.com/video.mp4'' name = 'file name' response = HttpResponse(file) response['Content-Disposition'] = f'attachment; filename={name}' return response but it cant return file for download. These codes return a file, but the file is not in the URL. how can I fix it? -
Handle file downloads in Flutter and InAppWebView?
I have a Django server with an endpoint to generate a PDF with some information entered by the user which returns a FileResponse (everything with a buffer, no file is created in the server, it is generated on demand), so the PDF is returned as attachment in the response. The endpoint is called in a HTML form submit button (in a Django template) and it works perfectly in all browsers. On the other hand, I did an app with Flutter (Android and iOS) using the InAppWebView library which opens my webpage. The problem comes when I try to download the PDF using the app. I have not found any way of handling the download file when it is returned as an attachment, for all methods I found I need the URL (which I can not call as I need the form information and the file is generated on demand). Summarizing: I have a Django server and a template with a basic form. On the form submit, it calls a python function that generates and returns a FileResponse with a PDF as an attachment and doesn't save any file in the server. On the other hand I have a Flutter WebView … -
Django authentication problem with mysql database
I am working on a Django project which uses Mysql database to manage user authentication and I also developed a custom user model with the AbstractBaseUser class I can migrate the table in the database and insert a user to the database by using the createsuperuser function and everything is ok but when I try to authenticate the mentioned user, the authenticate function returns None. The strange thing is that when I use default Myadmin db.sqlite3 database service of Django, authenticate function works correctly and returns the user username = 'p' password = 'p' user = authenticate(request , username=username, password=password) if user is not None: return HttpResponse('the user exist') else: return HttpResponse('the user does not exist in database') i also checked the charset of the columns in the database and it was utf8mb4_general_ci -

How to perform AES on username and password in REACT and DJANGO Python
I have followed to encrypt username and password AES in React based on the below link https://www.code-sample.com/2019/12/react-encryption-decryption-data-text.html using crypto-js const encryptedUsername = CryptoJS.AES.encrypt(usernameWithoutSpaces, SECRET_KEY).toString(); const encryptedPassword = CryptoJS.AES.encrypt(values.password, SECRET_KEY).toString(); I have used the SECRET_KEY as 16byte code which I randomly generated. And used this key for both encrypt and decrypt. I have followed the decryption based on https://devrescue.com/python-aes-cbc-decrypt-example/ from Crypto.Cipher import AES from Crypto.Util.Padding import unpad import base64 def decrypt_view(request): encrypted_username = request.data['username'] # Replace with your encrypted username encrypted_password =request.data['password'] # Replace with your encrypted password print("22222222222222",encrypted_username) # secret_key = b'\xd4\xa5?\xa5\xcd\x95\xees_\t\xa5\x9eI\x9d\x81\x95' # Convert your secret key to bytes secret_key =b'53d7311e6f8f88c0bbc4a08bccd7e254' decrypted_username = decrypt_data(encrypted_username, secret_key) decrypted_password = decrypt_data(encrypted_password, secret_key) print('Decrypted Username:', decrypted_username) print('Decrypted Password:', decrypted_password) def decrypt_data(encrypted_data, key): try: cipher = AES.new(key, AES.MODE_CBC, iv=b'1234567890123456') decrypted_data = unpad(cipher.decrypt(base64.b64decode(encrypted_data)), AES.block_size) # print("&&&&&&&&&&&&&&",decrypted_data) return decrypted_data.decode('utf-8') except Exception as e: print("DDDDDDDDDDDDDDD",e) with this encryption done at frontend and at backend couldn't decrypt as Error which i got as Padding is incorrect. Padding is incorrect. I have also used cryptography module and fernet which is in python to perform decryption. hence it doesnt suite with crypto-js. -
New Django Developer unable to get "Hello World" to display on website instead of the default installed successfully page
I am following along with a Django tutorial to create my first website. Everything was working according to plan until I reached the step that involved the URL Patterns. Specifically it is the include() function that made this project come off the rails. When I reach this point in the tutorial I run the server on my localhost. The default Django installed successfully homepage is displayed instead of the "Hello World" text that is my tutorial index page. I have double checked that my code matches both the tutorial that I am following as well as the official Django tutorial but my results do not change. I have checked several solutions from stackoverflow but have been unable to resolve this problem. /first_project/first_project/urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path("", include('first_app.urls')), path("admin/", admin.site.urls), ] first_project/first_project/settings.py INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", "first_app", ] /first_project/first_app/urls.py from django.urls import path from . import views urlpatterns = [ path("", views.index, name = "index"), ] first_project/first_app/views.py from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Hello World") One of the suggestions on stack overflow was under first_project/first_project/urls.py to change … -

Django scripts can't access files from docker volume
I add data folder (containing files with meta data) to the .dockerignore file. Because I don't want to weigh down my containers. don't want my containers to be too heavy. Since the datafolder contains huge files that need to bee read by the application. So I decided to mount a volume in my docker compose like below. And when I go inside the webcontainer I can see the file. And inside the container when I type /sigma/data/imports/dbm.csv I got the data. But when trying to read the file I goot this error : [Errno 2] No such file or directory: '/sigma/data/imports/dbm.csv' Am I missing ou misunderstood something?

Django large file upload (.dcm)
After the user starts uploading files of 1-2 gb on a page in Django, I want the user to be able to navigate on other pages while the upload process continues. How can I do it? I can upload the files to the server with the chunk method and merge them in the back. However, this upload process is interrupted when I switch to other pages. I want this to continue without interruption. I tried to create a structure with Django channels and send files with the chunking method of dropzone.js, but I failed. Only string data was sent. I also could not convert the chunk .dcm data to base64. I did not try the celery method.

How do i setup scheduling task on Django?
I've create a reporting module using Django for a project i have. Essentially what it does it has a list of reports where you can select a start date and end for the reports and run it. Then the report view runs a cursor query and fetches results. All of this works. But now i want to implement a queuing feature. Where you set a start date and end date then set a date time for the report to be automatically run (Which will be stored in a database) and keep the result. The user then can come back anytime to revisit the report without it being rerun What is the best way to achieve this? Thanks I've tried to use a cron job which run daily to check for reports and run them to achieve this but this fails to fulfill time scheduling -

connect to PostgreSQL server: FATAL: no pg_hba.conf entry for host "" with external database azure

Hotwire Turbo Frame in Django application stops django-bootstrap-datepicker-plus from showing
In my Django App I use a Turbo Frame in a DetailView. The Turbo Frame loads a form into the DetailView. This form has a datefield for which I use a Datepicker (django-bootstrap-datepicker-plus). If I call the form directly the Datepicker works just fine, but when the form is called into the DetailView via Turbo Frame the Datepicker does not show. Any suggestions on how to solve this and whats the underlying issue is?

Request Taking too long in Django
I have been trying to build a chemotherapy drug dose scheduling (mathematical model) as part of my thesis. Firstly I did the logic MATLAB and then implemented it in python. Then I tried using Django. While the app runs fine in localhost, but fails when I host it. Mainly because of the time it takes to calculate the whole process. In my localhost it takes around 40 seconds to 1 min to calculate but I get the result. When I host it in railway it gives up after first iteration. It is based on Fuzzy Logic. Also I didn't follow software development principle when creating this, so the code is a mess. I do not know what should I include for reference. I am adding the github link- FES Tool The error I get from railway is Application failed to respond. Any suggestion is apprecated. I tried to host a django project that takes a lot of time calculating in the backend and I failed. -
Is in django way save some data from database in RAM and after fixed time update it
For example I have some data that is fixed for all user. Now for each request I get the same data from DB. Is there way to optimize it. I tryed make a class which stores my needed data and init time by datetime; and it has method which gets current time, compare it with init time, and if difference more than 12 hours it makes new request to database, update value in class and returns it; else it returns old value. It works but i think that it isn't right way. Are some ideas? -
Implementing configurable feature-based roles and permissions in django rest framework
I have a scenerio where I am creating custom roles and assigning permissions to them for each fetaure. The process is fully customized and generic and it works for CRUD operations(like create user, read user, update user and delete user) perfectly. Now there is a little change in requirements where I have multiple operations for one feature like create order, accept order, split order, refer order. Now I want to create a roles and permissions so that it covers this part of my problem as well. Inititally I had four models i.e. Role, Permission, Feature, RoleFeatureAssociation(fields: role, feature, list(permissions)). I was checking permissions upon each request and if the particular user had that particular permission available for that feature then request was processed. Keeping this procedure in view as well how should I manage new requirements since I have multiple operations for feature instead of just create, read, update and delete. -
How can I make the user click on a button in a Django .html to modify one of the database values?
I have these two buttons found in my Django .html: <div class="d-flex justify-content-center" style="margin: 1em;"> <button type="button" class="btn btn-success btn-lg mx-2" style="width: 150px;">Accept</button> <button type="button" class="btn btn-danger btn-lg mx-2" style="width: 150px;">Reject</button> </div> What I need, is that when the user clicks on the button, that it changes a value, in this case of an invoice of my database. That is to say, now the invoice is in factura.id_estado=1; so, if the user clicks on Accept, factura.id_estado must change to 2 (factura.id_estado=2). The same happens when the user clicks on Reject, factura.id_estado will change to 3 (factura.id_estado=3). I don't know if it is necessary or not, but my database is the Django database which is hosted in my Docker.
