Handle exception if it raises inside view/models etc. #57

Remove duplicated code

I think that __import__(...) is duplicated code. I make a function then use it. The role of function is exception handling and importing.

But, I can't judge which style is more better. Which code do you prefer?

• self._import_app_module("{}.admin".format(app))
• self._import_app_module("{}.admin", app)

  Use traceback

Showing exception manually. Maybe extending this code, we can implement good exception handling.

The current style is good.

More than exception handling I think we need logging support. Currently we do not do any logging, and I think we should log some things, or even set up logging if its not set.
