I am now using MongoTalk for a project and I wanted to use distinct.
But there seems to be no support in the version that I do have.
So, I had a look under the hood on how the driver worked.
I came up with this:
mongo := Mongo default open.
db := mongo databaseNamed: 'somedb'.
aCommandDict := { 'distinct' -> 'somecollection'. 'key' -> 'XYZ'. 'query'
-> nil } asDictionary.
reply := db command: aCommandDict.
(CollectionValidation on: reply) isOK.
distinct := reply at: #values.
It would be nice to have some support for the distinct command in MongoTalk.
Especially in order to populate dropboxes etc with choices.
I have been looking at Voyage too but the data is not produced by my
application, so there is little use for me to have #instanceOf fields etc.
I will also need aggregation commands on my data set.
Are these things somewhere to be found or do I have to look into how the
shell does things and move from there?
TIA
Phil
