from-db-object returns WriteResult

[lawrenc...@gmail.com]

At the repl:

(require '[monger.conversion :refer :all])

(require '[monger.core :as mg]

            '[monger.collection :as mc])

(clojure.pprint/pprint (from-db-object (mc/insert database-object "User" { :hey "who"}) true))

returns:

#<WriteResult { "serverUsed" : "localhost:27017" , "n" : 0 , "connectionId" : 610 , "err" :  null  , "ok" : 1.0}>

Using Monger 2.0.0. 

I thought from-db-object was suppose to convert WriteResult to a Clojure data structure? That is what I read here:

It converts DBObject and collections but not write results.

We have never been asked about converting WriteResults.

I am confused. If I look here: 

https://github.com/michaelklishin/monger/issues/21 

Then, on that page, you wrote:

"WriteResults are indeed DBObject instances. You can convert them to Clojure maps using monger.conversion/from-db-object, just like with DBObjects, map/reduce results and command results."

But, as I showed in my first post, up above, when I try this at the repl, even after I run the return value through monger.conversion/from-db-object, it is still a WriteResult. 

I really only want to check the value of "ok". You have written that the Monger function ok? is deprecated and we should not use it. I don't really mind using the Java interop to deal directly with the WriteResult. I see the API here: 

http://api.mongodb.org/java/2.7.3/com/mongodb/WriteResult.html

I assume I can use getField("ok") to get the value of "ok". But is this what you recommend as best practice?

Testing the Java interop at the repl and all seems well:

(clojure.pprint/pprint (from-db-object (mc/insert database-object "User" { :hey "who"}) true))

#<WriteResult { "serverUsed" : "localhost:27017" , "n" : 0 , "connectionId" : 610 , "err" :  null  , "ok" : 1.0}>

nil

(def written (from-db-object (mc/insert database-object "User" { :hey "who"}) true))

#'user/written

(println (str (.getField written "ok")))

1.0

I guess this is how I'll proceed.
