KeyError: '_id' at eve_type = rd['schema'][lookup_field]['type']

i am unable to get eve- swagger to work with my eve-mongoengine/eve app.

my code looks like this

`from eve import Eve from eve_mongoengine import EveMongoengine from eve_swagger import swagger, add_documentation

init application

from models import *

all = ( 'create_connection', 'disconnect', 'get_connection', 'DEFAULT_CONNECTION_NAME', 'fetch_connection_settings', 'InvalidSettingsError', 'get_db' )

DEFAULT_CONNECTION_NAME = 'default-mongodb-connection'

MONGODB_SETTINGS = {

'MONGO_HOST': 'localhost',
    'MONGO_PORT': 27017,
#     'MONGO_USERNAME' : None,
# 'MONGO_PASSWORD': None,
'MONGO_DBNAME': 'ashrm3',
'X_DOMAINS': '*',
'ALLOW_OVERRIDE_HTTP_METHOD':'true',
'JSON_SORT_KEYS ':'true',
'DOMAIN': {'in': {}},

}

app = Eve(settings=MONGODB_SETTINGS)

init extension

ext = EveMongoengine(app) app.register_blueprint(swagger) app.config['SWAGGER_INFO'] = { 'title': 'My Supercool API', 'version': '1.0', 'description': 'an API description', 'termsOfService': 'my terms of service', 'contact': { 'name': 'nicola' }, 'license': { 'name': 'BSD' } }

register model to eve

ext.add_model([Item,MessageThreads,Messages])

let's roll

app.run(host='127.0.0.1', port=8001,debug=True)`

I haven't used Eve-Mongoengine, but I think this is a Eve-Mongoengine error. The problem is that Eve-Mongoengine doesn't include the '_id' field (which is the default item_lookup_field) in the schema. Eve-Swagger expects something like '_id': {'type': 'objectid'} in the schema of each resource.
