this questions

i want push in myarray if userid doesn't exists, should appended myarray. if userid exists, should updated point.

i found this

db.collection.update({   _id : objectid("57315ba4846dd82425ca2408"), "myarray.userid" :  objectid("570ca5e48dbe673802c2d035") },{    $set: {"myarray.$.point": 10} })

but if userid doesn't exists, nothing.

and

db.collection.update({   _id : objectid("57315ba4846dd82425ca2408") },{   $push: {"myarray": {userid: objectid("570ca5e48dbe673802c2d035"), point: 10}} })

but if userid object exists, push again.

what best way in mongodb.

try this

db.collection.update( { _id : objectid("57315ba4846dd82425ca2408")}, { $pull: {"myarray.userid": objectid("570ca5e48dbe673802c2d035")}} ) db.collection.update( { _id : objectid("57315ba4846dd82425ca2408")}, { $push: {"myarray": { userid:objectid("570ca5e48dbe673802c2d035"), point: 10 }} )

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
