# my example schema for a contentype
class IEntry(model.Schema):
providername = schema.TextLine(
title="Name",
required=True)
# in a test
entry = api.content.create(
type="Entry",
title="Entry",
description="This is a description",
container=portal
)
> pp entry.providername
> None
I thought this was going to fail, because the property "providername" is not set, but the object is created. Is this the default behavior of api.content.create?

plone.api works on a low level using invokeFactory and so does not validate the fields. I think this is by intend.
If you need validation, have a look at the plone.restapi deserializers. There validation happens.
Overall schema handling:
def get_schema_data(self, data, validate_all):
schema_data = {}
errors = []
for schema in iterSchemata(self.context):
write_permissions = mergedTaggedValueDict(schema, WRITE_PERMISSIONS_KEY)
for name, field in getFields(schema).items():
field_data = schema_data.setdefault(schema, {})
if field.readonly:
continue
if name in data:
dm = queryMultiAdapter((self.context, field), IDataManager)
if not dm.canWrite():
continue
if not self.check_permission(write_permissions.get(name)):
show original
and actual validation per field:
class DefaultFieldDeserializer(object):
def __init__(self, field, context, request):
self.field = field
if IField.providedBy(self.field):
self.field = self.field.bind(context)
self.context = context
self.request = request
def __call__(self, value):
if not isinstance(value, six.text_type):
self.field.validate(value)
return value
value = IFromUnicode(self.field).fromUnicode(value)
# IFromUnicode.fromUnicode() will validate, no need to do it twice
return value
@implementer(IFieldDeserializer)
@adapter(ITextLine, IDexterityContent, IBrowserRequest)
class TextLineFieldDeserializer(DefaultFieldDeserializer):
