 For brevity's sake, I'm avoiding constructing whole model instances below,
 but the issue remains the same when they are attached.
 {{{
 >>> from django.db.models.fields import CharField, TextField
 >>> CharField().to_python(1)
 u'1'   # type: unicode
 >>> TextField().to_python(1)
 1   # type: int
 }}}
 I'd expect that cleaning a `TextField` ought to result in a
 str/promise/smart_text as with CharField. The issue arises I believe
 because

 to_python] which is called by `get_prep_value`. Both fields seem to
 exhibit the same behaviour for the `get_prep_value`:
 {{{
 >>> CharField().get_prep_value(1)
 u'1'  # type: unicode
 >>> TextField().get_prep_value(1)
 u'1'  # type: unicode
 }}}

 From a cursory play in  [https://github.com/kezabelle/django-
 strictmodels/commit/1acad9ef63769fc6378c6d023333259c2a8cc41f#diff-
 4a6a4e7167b55119eefda4da703221edR160 my toy project], it seems like
 hoisting the `TextField.get_prep_value` logic into `to_python` and calling
 it from `get_prep_value` like `CharField` does would make the behaviour
 consistent.
