MongoDB question : is it possible to anonymise a field in a sub-document

[sylguyot]

sample of my json document:
{
"_id" : ObjectId("5ac34319dc0ef65f31755b60"),
...,
identity : {
"givenName" : [
"Nicolas"
],
"sn" : [
"GUYOT"
],
...
}
}

I have tried to anonymise identity.givenName with the code:

anonymize('identity.givenName').using FieldStrategy::AnonymizeArray.new(FieldStrategy::RandomFirstName.new)

no errors are thrown but it doesn't change the field value ...

example subdocument anonymization:
in case subdocument is array use:
https://github.com/sunitparekh/data-anonymization/blob/master/examples/mongodb_whitelist_dsl.rb#L34

in case of subdocument as hash use:
https://github.com/sunitparekh/data-anonymization/blob/master/examples/mongodb_whitelist_dsl.rb#L38

sample JSON document for above is:

let me know this solves your problem.
