----------------------------------+-----------------
Suppose I have a simple model:
{{{
class Simple(models.Model):
data = HStoreField(default={})
}}}
I can save hstore with mixed types, which is normal:
{{{
simple = Simple.objects.create(data = {'a': 1, 'b': 'B'})
}}}
But the `update` function throws an exception:
{{{
Simple.objects.filter(id=simple.id).update(data={'a': 1, 'b': 'B'})
}}}
{{{
