Django Application Deployed but Test Page Shows Default Page

Question

Django Application Deployed but Test Page Shows Default Page

jjmcinto 51

I deployed my code and confirmed it is present in the App Service on Linux but my test page shows the default page. It has been in this state for over a day, so I would say I have already tried the "wait-and-see" approach.

The top-level directory contains:

db.sqlite3
my main project folder
my app folder
manage.py
requirements.txt

I checked the log file and it shows no errors. I would like to solve this problem but do not know where to look next.

Hi.

Have you tried troubleshooting if the default page is displayed?
https://learn.microsoft.com/ja-jp/azure/app-service/configure-language-python#app-doesnt-appear

Restart the App Service, wait 15-20 seconds, and check the app again.
Be sure you're using App Service for Linux rather than a Windows-based instance. From the Azure CLI, run the command az webapp show --resource-group <resource-group-name> --name <app-name> --query kind, replacing <resource-group-name> and <app-name> accordingly. You should see app,linux as output; otherwise, recreate the App Service and choose Linux.
Use SSH to connect directly to the App Service container and verify that your files exist under site/wwwroot. If your files don't exist, use the following steps:
- Create an app setting named SCM_DO_BUILD_DURING_DEPLOYMENT with the value of 1, redeploy your code, wait a few minutes, then try to access the app again. For more information on creating app settings, see Configure an App Service app in the Azure portal.
- Review your deployment process, check the deployment logs, correct any errors, and redeploy the app.
If your files exist, then App Service wasn't able to identify your specific startup file. Check that your app is structured as App Service expects for Django or Flask, or use a custom startup command.

Thanks for your reply.

Yes, I saw the page with these steps and ran through them before posting this question. My files exist and are structured just like the sample project mentioned in a Quickstart article on microsoft.com. Is there any other possible cause/solution?

I just reproduced the quick start procedure perfectly.
What is the deployment method? I used Visual Studio Code and after a minute or two of deploying it worked as expected.

I want to reproduce your phenomenon, so please tell me the procedure.

To publish my project, I was following this page:
https://learn.microsoft.com/en-us/azure/developer/python/tutorial-python-postgresql-app-portal?pivots=postgres-flexible-server#

I was a little unsure because it does not seem to specify the expected file structure. Is there perhaps a more precise set of instructions I could follow?

I also attempted the 'Azure portal' method to publish the sample project (mentioned in my previous reply) but got stuck between steps 3 and 4. (I need more explicit instructions for how to "push code to the remote Git repository" on the Azure portal.)

Please follow this quick start once.

Quickstart: Deploy a Python (Django or Flask) web app to Azure - Azure App Service \| Microsoft Learn

From there, gradually approach the current configuration. You can see where the problem will be reproduced.

Thank you for the idea.

I published the example project but even that project does not work for me. I followed the instructions precisely until the end of step 3 (Deploy your application code to Azure, Deploy using Local Git), at which point I deployed the code by FTP (using the FTPS endpoint and ‘Application scope’ credentials from my application’s Deployment Center page). I have confirmed that the files were transferred successfully. However, this achieved the same results as with my own code - the test page is still showing the "waiting for your content” page.

I suspect that dumping the files by FTP may not be sufficient. It would be a lot better if, in step 3, there were detailed instructions regarding precisely how to "push code to the remote Git repository". Can you maybe help me fill in those details and/or tell where I might have gone wrong here?

Okay, I tried again and figured out how to publish the example project (Hello Azure) with Visual Studio Code. It worked as expected.

I will try to work out how to publish my own project with the same approach and return with either questions or immense gratitude.

Okay, I got it done. The VS Code approach was the answer. Now there are new problems (unrelated to publishing) but I think I can handle those. Thanks again!

FTP deployments don't build your app, see Deploy files to Azure. Your python app needs to be built on the worker so your dependencies can be installed, unless you intend to deploy those dependencies from your local machine. If you choose a different deployment method, make sure you have the SCM_DO_BUILD_DURING_DEPLOYMENT for the platform to build your app, see https://learn.microsoft.com/en-us/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet#build-automation for more info.
