errors with debug=False

Hello,

my web app seems to be working fine with debug=True, but when set to False, I get an internal server error. I have researched this topic in depth and I'll show you the steps I've taken based on what I've read.

ALLOWED_HOSTS=['www.mydomain.com']

I collected static files and wrote them in base.py as:

STATIC_ROOT = '/home/DavidW/Blog_Portfolio_App/static' STATIC_URL = '/static/'

MEDIA_ROOT = '/home/DavidW/Blog_Portfolio_App/media' MEDIA_URL = '/media/'

I also wrote the same for the pythonanywhere web section

I have a valid SECRET_KEY in my dev.py setting, which imports base.py.

the wsgi file points to my settings file and works fine for dev.py when debug is true.

Is there anything I'm missing? Please advise. I've read the relevent documentation from pythonanywhere and collectstatic from django.

Thank you

UPDATE:

I had these activated in my production.py but was set to TRUE, then later 'true' which is incorrect.

CSRF_COOKIE_SECURE = True

SESSION_COOKIE_SECURE = True

Also, DEBUG has to be set to 'FALSE' not FALSE or 'False,' and manage.py also has to point to the same place as the wsgi file. importing from .local works best at the bottom of the file as well. If anyone else is having issues, I hope this helps.

Glad you worked it out, and thanks for posting your solution!

Woow

It worked

What worked for me was setting debug='FALSE' with inverted commas

Thanks

I know the exact solution of the media files are not loading error while setting debug to false. Sol : Be sure not to keep slash at the end of the url of media files in templates, or it will return the error.

That's it. Thank you .

None of the solutions above are the correct solution to the problem.

Just set the Debug = False

MEDIA_URL = '/media/'

MEDIA_ROOT = '/home/myusername/myproject/media'

Generally on PythonAnywhere you'd need an extra step to set up static files mappings.

Thanks @pafk, yes you need to set up a static files mappinp!!

The image shows a forum post on onanywhere.com about an internal server error occurring when the  debug  setting is set to  False  in a web application. The user is troubleshooting the issue. They've already taken several steps, including:

  • Setting  ALLOWED_HOSTS : This is crucial for production deployments to prevent security vulnerabilities. It specifies which hostnames are allowed to access the application. The user has set it to  ['www.mydomain.com'] .
  • Managing Static and Media Files: They've configured  STATIC_ROOT ,  STATIC_URL ,  MEDIA_ROOT , and  MEDIA_URL  in their  base.py  settings file. This correctly points to the locations of static files (like CSS, JavaScript, and images) and media files (like uploaded user content). The paths indicate the files are stored within the user's home directory on the server.
  • Setting  SECRET_KEY : A valid  SECRET_KEY  is present in their  dev.py  settings file, which is imported by  base.py . This is essential for security and session management.
  • WSGI Configuration: The WSGI file correctly points to the settings file and functions properly when  debug  is  True .

The Problem: The application works fine with  debug=True , but fails with  debug=False . This is a common issue. The  debug=True  setting provides detailed error messages, which are suppressed when  debug=False  for security reasons. The internal server error suggests a problem that's not being caught or handled gracefully in the production setting.

Possible Solutions:

1. Detailed Error Logging: When  debug=False , the application should log errors to a file. Examine this log file for clues about the cause of the error. The log file will contain much more specific information than the generic "internal server error" message. 2. Check for Missing Dependencies: Ensure all required packages are installed in the production environment. The production environment may be missing packages installed in the development environment. 3. Deployment Differences: The development and production environments might have subtle differences in their configurations (e.g., different versions of Python, different database configurations, or missing environment variables). 4. Incorrect File Paths: Double-check that the paths in  STATIC_ROOT  and  MEDIA_ROOT  are absolutely correct for the production server. A small typo can cause this kind of error. 5. Database Connection: If the application uses a database, confirm the database connection is correctly configured in the production settings. 6. Permissions: Verify that the web server has the necessary permissions to access the files and directories specified in  STATIC_ROOT  and  MEDIA_ROOT . 7. Deployment Process: The deployment process itself could be faulty. A clean deployment (restarting the server, etc.) might resolve the problem. 8. Code Errors: There might be subtle errors in the code that only manifest when  debug=False  because the exception handling is not robust enough.

In short: The user needs to investigate the server logs for more detailed error messages to pinpoint the specific problem. The issue is likely related to a configuration discrepancy between the development and production environments, a missing dependency, or a subtle error in the application's code that isn't caught by the  debug=True  setting.
