Support needed for Django app deployment on Heroku

Question

I have an app I'd like to deploy on Heroku. Not finished yet but it's now a requirement from my teacher. I created an account and app on heroku and use the GitHub deployment method but when I click on deploy branch I have the following type of error:

 FileNotFoundError: [Errno 2] No such file or directory: '/tmp/build_0f3c3e792cd2015b5d316aad8cf28d6c/static'
 !     Error while running '$ python manage.py collectstatic --noinput'.
       See traceback above for details.
       You may need to update application code to resolve this error.
       Or, you can disable collectstatic for this application:
          $ heroku config:set DISABLE_COLLECTSTATIC=1
       https://devcenter.heroku.com/articles/django-assets
 !     Push rejected, 

Can you help me understand the error and solve it?

I'd like to use this deployment method if possible as I am very much a begginer in git too and I'd like to avoid doing it with CLI for now.

Thanks,

Answer 1

I don't know what is the state of your settings but make sure your static urls are all created in settings.py . Specially the STATICFILES_DIRS which will set a place to collect the statics for production.

Please follow this Heroku KB: https://devcenter.heroku.com/articles/django-assets |

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/1.9/howto/static-files/
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'

# Extra places for collectstatic to find static files.
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

Then it should collect static in the right folder. Let me know.

Please use whitenoise to deploy static files on heroku.
