Creating unique index in pyarango arangodb

Question

I am trying to add an unique index to my collection. I am writing code:

conn = Connection()
db = conn['textBook']
db['Users'].ensureHashIndex('word', unique = True);

(There is database 'textBook' with collection 'Users' existing.)

pyArango.theExceptions.CreationError: bad parameter. Errors: {u'errorMessage': u'bad parameter', u'errorNum': 10, u'code': 400, u'error': True}

It is occuring while creating Index in function _create (raise CreationError(data['errorMessage'], data) )

Which parameters are incorrect?

Answer 1

您需要在列表中提供字段，因此请尝试以下操作：

db['Users'].ensureHashIndex(['word'], unique = True)
