Splunk Apps » Website Input

The controller is importing a Field instance that does not have required_on_create. From what I can tell, it is importing the Django apps modular input library.

The controller isn't importing its own version of the modular input library but the Django app version of it

The issue is that each of the apps updates sys.path to import libraries. Multiple on the file-system can cause collisions when running in SplunkWeb since they inevitably wind up changing each other's sys.path. In this case, website_input got django_monitoring's sys.path updates and imported its modular input class.

I fixed this by putting the sub-class in a sub-directory titled after the app name and then using it as a module to be imported. This worked.
