Thank you for your response, Cliff.
But the strip-command wasn't my problem. I wondered why Django let pass
these kind of invalid input and if there is an easy way to toggle this
behavior for the whole project. I could not find anything in the Django
docs.
Now I'm thinking of overwriting the to_python-Method of the models
charField-class.
Or are there better solutions?
