I'm getting some difficulties to call a stored function within mongdb. I'm a little bit newbie with mongo.
[EDIT] : my function stored in mongodb
function() {
var cndTime = new Date().getTime() - (3600*1000*24*2); // condition
db.urls.find(needParse: false).forEach(function(item){
if(item.date < cndTime) // check
db.urls.update({_id: item._id}, {$set: { needParse: true }}); // update field
});
}
All I'm asking is how to invoke this function using reactivemongo or native API.
Consider the following example from the mongo shell that first saves a function named echoFunction
to the system.js
collection and calls the function using db.eval()
:
db.system.js.save({
_id: "echoFunction",
value: function (x) {
return 'echo: ' + x;
}
})
db.eval("echoFunction('test')") // -> "echo: test"
echoFunction(...)
is available in eval
/$where
/mapReduce
etc. more information is available at http://docs.mongodb.org/manual/tutorial/store-javascript-function-on-server
