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?

A hot guess would be that you need to specify the fields the index is created on as you need to in js: docs.arangodb.com/IndexHandling/Hash.html - this most probably maps to python like this: {fields: [ "word"]}; depending on the implementation only adding brackets [ ] to get a list may work. — dothebart

You need to provide fields in a list, so try this:

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