用django在heroku上部署bootstrap

Question

I am having trouble with deployment of twitter bootstrap on my heroku client. My html code is not showing like it should (alignment, special table layouts, etc)

All is working locally, but i assume it has to do with the static files that don't get transferred correctly.

This is the static file structure, but have a look how it looks like when i open the "source chrome console" on my live heroku verson.

View of how the folder structure should be

Folder structure of deployed code on heroku

It looks like some folders are "stitched" one to another. what could be my issue? should i avoid "-" and "_" in my file names?

thanks for the help.

based on extra questions, I added more info on my settings.py file. I followed a tutorial to get all the stuff right. Also whitenoise was installed, added to wsgi.py.

wsgi.py

Answer 1

After having a thorough discussion with hansTheFranz, it became clear that the issues had to do with missing files.

A default gitnore used in my sourcetree application that i used for syncing with github, prevented several static folders to upload to my git. removing these folders from this gitnore file did the trick.

thanks for the help guys!

Answer 2

Go to heroku static assets documentation for Django:

Heroku Documentation: Django and Static Assets

Everything is illustrated there in detail, make changes in settings.py and install whitenoise and it will work.
