Heroku教程错误运行python manage.py syncdb更新本地数据库

Question

This question has been asked before and answered here , and I understand the reasoning as to why I am getting the error, however I am still unclear about the solution from the answer given. What code or changes should I be adding to make it work? Do I need to make changes to

 DATABASES['default'] =  dj_database_url.config()

in my settings? The tutorial isn't very clear about this. Thanks for any help.

Answer 1

设置并使用带有DATABASE_URL config var的virtualenv ，或使用DATABASE_URL=postgres:///databasename <how you'd normally run your program>

Answer 2

What ended up working eventually was to add:

import dj_database_url
DATABASES['default'] =  dj_database_url.config(default='postgres://<user>:<password>@localhost:5432/<name>')

instead of just

import dj_database_url
DATABASES['default'] =  dj_database_url.config()

like the tutorial states. Then when trying to run

python manage.py runserver

I still got the error

ImportError: DLL load failed: %1 is not a valid Win32 application.

I then was able to figure out that the stickpeople build i needed to use was the 64 bit instead of the 32 bit that the tutorial had me use, and the 64 bit build is:

easy_install http://www.stickpeople.com/projects/python/win-psycopg/psycopg2-2.4.5.win-amd64-py2.7-pg9.1.3-release.exe

I don't know if it was the best way, but in order to use the 64 bit build I started over from the beginning. Now it finally works. Hopefully this can also be used to help anyone else who is also stuck. There are a lot of holes in the heroku tutorial.
