Using findAndModify with GMongo

I'm trying to make an auto incrementing field in MongoDB as described here: http://www.mongodb.org/display/DOCS/How+to+Make+an+Auto+Incrementing+Field
Here's my field: > db.counters.find() { "_id" : "entryId", "c" : 1 } I tried to use findAndModify from GMongo like this: def counter = db.counters.findAndModify([_id: "entryId"], [$inc: ['c':1]]) which gives me the exception: groovy.lang.MissingMethodException: No signature of method: com.mongodb.DBApiLayer$MyCollection.findAndModify() is applicable for argument types: (java.util.LinkedHashMap, java.util.LinkedHashMap) values: [[_id:entryId], [$inc:[c:1]]] Possible solutions: findAndModify(com.mongodb.DBObject, com.mongodb.DBObject), findAndModify(com.mongodb.DBObject, com.mongodb.DBObject, com.mongodb.DBObject) at com.gmongo.internal.Patcher$__patchInternal_closure1.doCall(Patcher.groovy:41) at no.nsb.rapp.client.ClientReportController$_closure4.doCall(ClientReportController.groovy:90) at no.nsb.rapp.client.ClientReportController$_closure4.doCall(ClientReportController.groovy) at grails.plugin.springcache.web.GrailsFragmentCachingFilter.doFilter(GrailsFragmentCachingFilter.groovy:66) at net.sf.ehcache.constructs.web.filter.Filter.doFilter(Filter.java:86) at net.bull.javamelody.MonitoringFilter.doFilter(MonitoringFilter.java:157) at net.bull.javamelody.MonitoringFilter.doFilter(MonitoringFilter.java:131) at java.lang.Thread.run(Thread.java:680) Using exactly the same parameters to 'update' works fine: db.counters.update([_id: "entryId"], [$inc: ['c':1]]) and it looks to me that the signature of 'findAndModify' is equal to the signature of 'update': public com.mongodb.WriteResult update(com.mongodb.DBObject q, com.mongodb.DBObject o) throws com.mongodb.MongoException public com.mongodb.DBObject findAndModify(com.mongodb.DBObject query, com.mongodb.DBObject update) I also tried adding 'as BasicDBObject' to the parameters, like on this blog: http://jameswilliams.be/blog/entry/165 But to no success Do anyone have a solution to this?

This isn't really a Groovy question and is more appropriate for the
MongoDB mailing list since it relates to use of the MongoDB Java driver. Anyway looking at the javadoc http://api.mongodb.org/java/2.6.5/com/mongodb/DBCollection.html#findAndModify(com.mongodb.DBObject, com.mongodb.DBObject) findAndModify takes 2 DBObject parameters not maps Cheers On Wed, Oct 5, 2011 at 8:11 AM, Ronny Løvtangen <[hidden email]> wrote: > I'm trying to make an auto incrementing field in MongoDB as described here: http://www.mongodb.org/display/DOCS/How+to+Make+an+Auto+Incrementing+Field > > Here's my field: > >> db.counters.find() > { "_id" : "entryId", "c" : 1 } > > > > I tried to use findAndModify from GMongo like this: > > def counter = db.counters.findAndModify([_id: "entryId"], [$inc: ['c':1]]) > > which gives me the exception: > > groovy.lang.MissingMethodException: No signature of method: com.mongodb.DBApiLayer$MyCollection.findAndModify() is applicable for argument types: (java.util.LinkedHashMap, java.util.LinkedHashMap) values: [[_id:entryId], [$inc:[c:1]]] > Possible solutions: findAndModify(com.mongodb.DBObject, com.mongodb.DBObject), findAndModify(com.mongodb.DBObject, com.mongodb.DBObject, com.mongodb.DBObject) > at com.gmongo.internal.Patcher$__patchInternal_closure1.doCall(Patcher.groovy:41) > at no.nsb.rapp.client.ClientReportController$_closure4.doCall(ClientReportController.groovy:90) > at no.nsb.rapp.client.ClientReportController$_closure4.doCall(ClientReportController.groovy) > at grails.plugin.springcache.web.GrailsFragmentCachingFilter.doFilter(GrailsFragmentCachingFilter.groovy:66) > at net.sf.ehcache.constructs.web.filter.Filter.doFilter(Filter.java:86) > at net.bull.javamelody.MonitoringFilter.doFilter(MonitoringFilter.java:157) > at net.bull.javamelody.MonitoringFilter.doFilter(MonitoringFilter.java:131) > at java.lang.Thread.run(Thread.java:680) > > > Using exactly the same parameters to 'update' works fine: > > db.counters.update([_id: "entryId"], [$inc: ['c':1]]) > > and it looks to me that the signature of 'findAndModify' is equal to the signature of 'update': > > public com.mongodb.WriteResult update(com.mongodb.DBObject q, com.mongodb.DBObject o) throws com.mongodb.MongoException > public com.mongodb.DBObject findAndModify(com.mongodb.DBObject query, com.mongodb.DBObject update) > > > I also tried adding 'as BasicDBObject' to the parameters, like on this blog: http://jameswilliams.be/blog/entry/165 > But to no success > > Do anyone have a solution to this? > > Thanks, > Ronny Løvtangen > > > > > --------------------------------------------------------------------- > To unsubscribe from this list, please visit: > > http://xircles.codehaus.org/manage_email > > > -- Graeme Rocher Grails Project Lead SpringSource - A Division of VMware http://www.springsource.com --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |

Thanks Graeme.
I think the problem is with GMongo. The Java driver takes 2 DBObject parameters for update as well, but with GMongo you use maps, and then there's some magic happening. But for some reason this magic does not happen with findAndModify. Maybe GMongo has no support for findAndModify yet, so I have to use the Java driver directly.
