Django: No Module named 'foo' issue in context with model import
Background information: I would like to run a script using atoms script plug-in. I first encountered a ImproperlyConfigured error which was solved as suggested here: First fix Then I run into RuntimeError: Model class models.AccountInformation doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. error which was solved by using an absolute path for the model import as shown below.
