Django Forms and Formset edit
I am trying to create a edit fbv but my edit is not saving up. views.py def editplayform(request,id): play = Play.objects.get(id=id) if request.method =='POST': form = forms.PlayForm(request.POST, instance=play) time_shown_formset = forms.TimeShownFormSet(request.POST, instance=play) if form.is_valid() and time_shown_formset.is_valid(): form.save() time_shown_formset.save() return redirect("play:home") else: form = forms.PlayForm(instance=play) time_shown_formset = forms.TimeShownFormSet(instance=play) return render(request, 'play/fbvplayform.html', context={'form':form, "time_shown_formset":time_shown_formset, 'play':play}) edit.html <form method="POST"> {% csrf_token %} <h1>Edit PLAY</h1> <div>{{ form.non_form_errors }} {{ form.as_p }}</div> <h1>Edit Timeshown</h1> <!-- prettier-ignore --> {{ time_shown_formset.non_form_errors }} {{ time_shown_formset.management_form}} {% for form in time_shown_formset %} <div>{{ form.times.label }}: {{ form.times }}</div> {% if time_shown_formset.can_delete %} <div>{{ form.DELETE }} {{ form.DELETE.label }}</div> {% endif %} {% endfor %} <div> <button type="submit">Update Play</button> </div> </form> It is returning POST response on the terminal but the edit is not saving and its not returning to home.html.

Is there a way to specify library types and versions on GitHub other than using requirement.txt?
I've been exploring different approaches to specify library types and versions on GitHub for my solo project using Django and React. In my research, I've predominantly come across the use of requirement.txt files for managing project libraries. I've tried reviewing documentation and online discussions, but I'm curious to hear from the community about their experiences. Specifically, I'm interested in knowing if using requirement.txt is a widely adopted practice in the industry for managing project dependencies. Additionally, I'm open to learning about alternative methods that developers might find effective. What approaches have you tried for specifying library types and versions in your GitHub projects, and what were your expectations regarding the ease of maintenance and collaboration? Thank you for sharing your insights! -
Django Rest + Vuejs axion CSRF not working
I try using Django Rest Framework together with VueJS and axion. But always I get the MSG: CSRF Failed: CSRF token missing. But my Header in the frontend looks correct. And in the developer tools the cockie is correct loading into the header. {"Accept": "application/json, text/plain, /","Content-Type": "application/json","X-CSRFToken": "*******"} my csrf settings in django settings.py CSRF_COOKIE_NAME = "csrftoken" CSRF_HEADER_NAME = 'X-CSRFTOKEN' CSRF_TRUSTED_ORIGIN = ['http://.127.0.0.1', 'http://.localhost'] CSRF_COOKIE_HTTPONLY = False CSRF_COOKIE_SECURE= False I have no problems with the get requests. Only than it come to POST, PUT, DELETE. Thank you for your advice. With regards Philipp Homberger I try: CSRF_TRUSTED_ORIGIN = ['http://*.127.0.0.1', 'http://localhost'] as well. My Dev deployment build with 3 docker images. 1 Nginx as reversproxy to get both on the same port. 1 Container with Bakcend (Django) 1 Container with VueJs Frontend. What were you expecting? I expecting that I can do Post Requests as well without disable CSRF. Than I use the swagger frontend of my restapi all work fine as well. -
User can chose from a great amount of configurations/templates, need a way to handle without creating Django views/forms for every single one
Currently i am working on a project in Django which will let the user generate a router/switch configuration based on what type of service/router brand/router model he chooses. View: config list (List of registered configurations to generate) User -> Service_1 for router X model Y Then i would need to present the user with a page which will take the inputs needed to generate such configs View: generate config (Form that will ask the user for inputs needed to create X config file) Ex.: IP Address / Subnet Mask / is DHCP needed / routes needed This input will then be passed to variables which will be used to populate a jinja2 template file for said service/router model/router brand in a function Assume the structure is: -Router Brand X --Model Y ---Service1.j2 ---Service2.j2 ---Service3.j2 --Model Z ---Service1.j2 ---Service2.j2 ---Service3.j2 -Router Brand Y --Model Y ---Service1.j2 ---Service2.j2 ---Service3.j2 --Model Z ---Service1.j2 ---Service2.j2 ---Service3.j2 I have a big part of the project already done, right now i can save the config templates to my database, show said templates for the user to choose from and i gave it a try to create a page to generate the config.

Arcpy not supporting in djnago in all machine but some machine it supporting
I have a Django application running in a virtual Conda environment generated from ArcPro. I need to use the arcpy library in this Django application, which is why I used the virtual environment. However, the class I used with arcpy is working on some machines but not on others. I used the subprocess method, and it worked at that time since arcpy is running outside of Django with that method. Why is arcpy not compatible with Django? -

Django allauth + React google social login
I have django-allauth working well with Google social login when I'm directly accessing the backend. I'm now wondering how to use this from (or replace with) my React frontend. Originally my backend was FastAPI and with fastapi-users and it was working well enough with React. That is, in React I have a useAuth hook which in turn relies on useContext, while my React button would GET the auth_url from the backend's /auth/google/authorize, redirect me, use the /auth/google/callback, and ultimately store the token in a cookie. With Django I now wonder what the general approach should be. Should I: Option A: have my React button take me to django-allauth's /accounts/google/login, where the user completes the login cycle and is ultimately redirected back to my React's /profile? The issue so far is that even though the backend google part seems to work, upon redirect React complains that the token is empty. For now this is not surprising since I'm not yet sending that token back to the frontend. But idk if to keep working on this approach or if instead I should... Option B: try to recreate the /auth/google/authorize and /auth/google/callback flow I had working with FastAPI but now using Django. Specifically … -
Nginx + Gunicorn: Django Application Not Loading on Domain, But Works on IP and Port
I've tried accessing my Django application using the configured domain (e.g., http://succyloglobalfx.com) after ensuring that the domain is correctly pointing to the VPS IP address. I expected to see my Django application load successfully, similar to when accessing it via the IP address and port (e.g., http://162.254.35.54:8000). I run Gunicorn with the following command: gunicorn --bind 0.0.0.0:8000 TransferPrj.wsgi However, when accessing the application through the domain, I only encounter the default Nginx welcome page instead of my Django application. This behavior is unexpected, and I'm seeking guidance on what steps I can take to troubleshoot and resolve the issue. Below is my nginx config file server { listen 80; server_name succyloglobalfx.com www.succyloglobalfx.com; return 301 https://$host$request_uri; } server { listen 443 ssl; server_name succyloglobalfx.com www.succyloglobalfx.com; ssl_certificate /etc/letsencrypt/live/succyloglobalfx.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/succyloglobalfx.com/privkey.pem; include /etc/nginx/snippets/ssl-params.conf; # Include recommended SSL parameters location /static/ { alias /opt/myproject/myproject/Trabsfer/static/; } location / { include proxy_params; proxy_pass http://162.254.35.54:8000; # server ip address proxy_set_header X-Forwarded-Host $server_name; proxy_set_header X-Real-IP $remote_addr; add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"'; } } Any insights or troubleshooting steps would be greatly appreciated.

Having issues with importing model to another app in order to use model there

How can we transfer ERC721 tokens through MetaMask and JavaScript?
We are trying to develop an NFT marketplace in a Django project. At this point we know how to integrate MetaMask with our project and use the JavaScript MetaMask API to send ETH transactions ('eth_sendTransaction') or check the balance of a wallet. But we would also know how to transfer NFT (ERC721) tokens between wallets (allow users to buy their NFTs) with and endpoint of this JavaScript API for MetaMask. If it's possible, we would like to have the transfer of the ERC721 token and the amount of ETH payed in the same transaction. Like it's shown in the image below: Example of SepoliaETH token transfer Is there any endpoint in the link below which can help us solving this issue? MetaMask API Thank you We tried to use scripts but we don't want to have the private keys of the users' wallets in our marketplace server because we don't have the permissions to store this kind of data. -

Can I use AES Encryption in Django + MySQL? If yes, will it affect the use of Django's ORM and other features?
We are migrating our PHP codebase to Django. In the current application, all database columns are encrypted (except ID) using AES_ENCRYPT and AES_DECRYPT. something like this: $sql = " INSERT INTO users SET username = AES_ENCRYPT('".$email."','".$key."') , email = AES_ENCRYPT('".$email."','".$key."') "; $sql = "SELECT id , AES_DECRYPT(username ,'".$key."'), AES_DECRYPT(email,'".$key."')" Can this code be replicated in Django and is it possible to still maintain the cool features of Django like migration and ORM? -

I also have another instance of Celery running on the main service side. **Question:** Is there a way to monitor the state of the Celery worker and automatically return the task back to the queue if the worker dies or is killed? **Additional Information:** - Using visibility_timeout is not suitable as it would require waiting for a day before the task returns to the queue, while I need it to happen almost instantly. -
Design and architecture of Blood Donation Managment in Django
I have almost completed the famous Django tutorial; Writing your first Django app. To consolidate my concepts I want to do a project in Django. So, I am starting a Blood Donation Management System in Django. It is supposed to serve as a network of blood donors and seekers, both the donors and seekers will be able to register, and search through blood group type, and the search result will show list the list of donors/seeker along with the contact details. This way it going to serve the blood donors/seekers community. What I want here is only a design level guidance; What apps should I create. What should the model (tables and attributes) What views should I code I cannot figure out the project structure or a sketch that I should follow. Initially I want only a sketch of the design to have a roadmap to follow along. Best Regards
