one method for using mongoose objects

[илья мотылев]

This question duplicates http://stackoverflow.com/questions/22247186/one-method-for-using-mongoose-objects

I would like to create one method to call like this:

this.DoSomethingWithDb(this.someObject.findOne, conditions, this.RegisterDBCallback, additionalParams);

Inside DoSomethingWithDb I try to execute query, but it raise error.

myboj.prototype.DoSomethingWithDb = function DoSomethingWithDb(dbMethod, conditions, callback, params) {
    dbMethod(conditions, function(err, doc) {
        if (err) {

            return;
        }

        if (typeof callback === 'function') {
            callback(doc, params);
        }

    });
};

Part of error callstack:

....node_modules\mongoose\lib\model.js:949 this._applyNamedScope(query);

 

^ TypeError: Object # has no method '_applyNamedScope' at findOne (...\node_modules\mongoose\lib\mode l.js:949:8)

 

at DoSomethingWithDb (....server.js:2103:2)

Solved by passing query object onto DoSomethingWithDb
