I have an ArrayField with IntegerField inside, and the IntegerField has
choices.
Widgets return back a list of strings (instead of a list of integers).
That is why the validation fails.
I've found that changing ArrayField.to_python from this
{{{
def to_python(self, value):
if isinstance(value, six.string_types):
# Assume we're deserializing
vals = json.loads(value)
value = [self.base_field.to_python(val) for val in vals]
return value
}}}
to something like this
{{{
def to_python(self, value):
if isinstance(value, six.string_types):
# Assume we're deserializing
vals = json.loads(value)
value = [self.base_field.to_python(val) for val in vals]
elif isinstance(value, list):
value = [self.base_field.to_python(val) for val in value]
return value
}}}
fixes the problem.
