Heroku deploy not working

[vonpupp]

Hello,

I'm trying to deploy this app to Heroku. I'm new to Django and Heroku. I'did this and it didn't work

• Fresh clone
• Edited env/DATABASE_URL
• make initialdeploy

I also tried locally, when I try to run it with foreman start, I get: "This webpage is not available", and I noticed that the url changes to https instead of http.

Heroku error log:

make initialdeploy

Note that if I run heroku run python manage.py syncdb, I don't get any error on the console, but it still doesn't work at the end.

Files in env/ are only for local development. On heroku you need to create the corresponding environment variables via heroku config. It seems your DJANGO_SETTINGS_MODULE isn't set on heroku.

Thanks a lot Bruno.

Now I do have the environment variables on Heroku, but it still doesn't work. I'm trying to troubleshoot locally, when I try to run it with foreman start, I get: "This webpage is not available", and I noticed that the url changes to https instead of http.

Where I can either put the certificate or change to http?

Thanks again.

[brutasse]

Can you show:

• the list of environment variables you have
• the Foreman output when you try to access the local site
• the full URL that your browser tries to access when you get the "This webpage is not available" error message.

Locally you don't need HTTPS. Things should just work with foreman start -f Procfile.dev.

[vonpupp]

Thanks for your reply Bruno,

I got the prior error "This webpage is not available", when I tried to change some settings on settings.py to remove SSL, but I checked out to the original settings.py to make sure I'm not modifying your original code.

If I run it locally with foreman start -f Procfile.dev it works fine, but when I try it with the default Procfile (foreman start) it doesn't seems to work (error below).

Error:

SSL connection error
Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

Questions:

• Having S3/AWS is mandatory for deploying on Heroku? If yes, is there any way to avoid S3?
• Is it possible to run it with foreman start locally? How?

Thanks a lot for your help!

[brutasse]

Ok, the settings assume that when you deploy you run the site over SSL:

https://github.com/brutasse/djangopeople/blob/master/djangopeople/settings.py#L189-L214

On heroku you have SSL for free on your .herokuapp.com domain. Otherwise you have to pay them to activate SSL + get a valid certificate.

AWS is used for the staticfiles storage backend (S3) and for sending emails (SES). One way to avoid S3 would be to use dj-static instead. As for emails, you need some kind of email service.

foreman start simulates the production environment. To run locally, use foreman start -f Procfile.dev or python manage.py runserver.

Thanks Bruno,

I noticed some errors on heroku logs, the first one seems to be solved by adding heroku config:set CANONICAL_HOSTNAME=young-reaches-4943.herokuapp.com. Later I tried adding dj-static to the requirements and changing the wsgi.py script and run make deploy.

Now it seems to work, even that I need to tune the static files location... I will do more tests. Would it be possible to have the static files in another [sub]domain by copying the djangopeople/static folder? Something like static.anotherdomain.com? What should I change in that case?

I will also try to deploy to http://hosting4django.net/ to see if it's easier than heroku, but it doesn't seems likely.

Thanks a lot for your help.

[brutasse]

If you want the static files on another domain:

• Set STATICFILES_STORAGE to its default value of 'django.contrib.staticfiles.storage.StaticFilesStorage'
• Run python manage.py collectstatic --noinput on your development environment
• Copy the files to the domain/subdomain you want
• Alter STATIC_URL to point to that domain.

[vonpupp]

Thanks a lot Bruno,

I will try that. So far it seems to work fine with Heroku.

I appreciate your patience, help and support.

Regards!

@vonpupp great, have fun :)
