Hello at all!
I'm trying to customize tgext.admin to the needs of my application:
Since I have some PickleType columns in my model that should only be filled
by uploading plain files, I created the following form:
class TestEditForm(EditableForm):
__model__ = Test
__require_fields__ = ['type']
__omit_fields__ = ['id', 'assignment_id']
__field_order__ = ['assignment', 'type', 'visible', 'timeout',
'argv', 'input', 'output']
input = FileField(id='input',
validator=FieldStorageUploadConverter(not_empty=False))
output =
FileField(id='output',validator=FieldStorageUploadConverter(not_empty=False))
which is included via
class TestCrudConfig(CrudRestControllerConfig):
edit_form_type = TestEditForm
and
class MyAdminConfig(AdminConfig):
test = TestCrudConfig
Now if there is already data in the input/output columns, it just gets
overwritten with None if the file isn't uploaded again.
Am I missing a parameter to accomplish this non-overwriting behaviour?
Or could someone tell me some hackish way to achieve this!
Thanks a lot,
Moritz
