Resolving Django Deployment Issues on Vercel

Based on the error shown in your screenshot and your configuration files, there are several issues that need to be addressed for a successful Django deployment on Vercel.

Main Issues

From what I can see in your configuration, there are a few potential problems:

1. The collectstatic command is failing, likely because your Django settings aren't properly configured for a production environment
2. Your static files configuration in vercel.json may not be correctly set up
3. You might be missing some required environment-specific settings

Recommended Fixes

1. Update your build_files.sh

Modify your build script to run collectstatic with the --noinput flag to avoid prompts:

BASHCopied
#!/bin/bash

pip install -r requirements.txt

python3.11 manage.py collectstatic --noinput

2. Configure STATIC_ROOT in settings.py

Make sure your Django settings include proper static file configuration:

PYTHONCopied
# In settings.py
import os

# Static files configuration
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')  # or another directory of your choice

3. Update Environment-Specific Settings

Ensure these critical settings are properly configured in your settings.py:

PYTHONCopied
# Production settings
DEBUG = False  # Set to False in production

# Configure allowed hosts
ALLOWED_HOSTS = ['.vercel.app', 'your-custom-domain.com']  # Add your Vercel domain

# Configure static files
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

4. Create a WSGI Handler for Vercel

Create or update your WSGI file to properly handle Vercel's serverless environment:

PYTHONCopied
# problem2/wsgi.py
import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'problem2.settings')

# This is the application object needed by Vercel
application = get_wsgi_application()

# Add this for Vercel serverless function
app = application

5. Update vercel.json Routes

Your routes configuration looks good, but make sure it aligns with your STATIC_ROOT:

JSONCopied
{
  "version": 2,
  "builds": [
    {
      "src": "problem2/wsgi.py",
      "use": "@vercel/python",
      "config": {"runtime": "python3.11", "buildCommand": "bash build_files.sh"}
    }
  ],
  "routes": [
    {
      "src": "/static/(.*)",
      "dest": "/staticfiles/$1"  // Make sure this matches your STATIC_ROOT
    },
    {
      "src": "/(.*)",
      "dest": "problem2/wsgi.py"
    }
  ]
}

Additional Deployment Checklist Items

For a successful Django deployment, also ensure:

1. Your SECRET_KEY is properly secured (use environment variables)
2. Database configurations are set correctly for production
3. Error views are customized (create templates for 404.html, 500.html, etc.)
4. HTTPS settings are properly configured

By addressing these issues, you should be able to successfully deploy your Django application on Vercel.
