Is there a way to avoid hard coding with Mongoose?

Question

Consider the following code, where 'Team' is a mongoose model.

var Team = mongoose.model( 'Team' );
Team.find({'GroupName':gname}, function (err, teams) {
   // Some code
}

How do I get rid of this hard coding where I hard code 'GroupName':gname during selection in mongo?

Answer 1

One approach is to define static methods on your model that expose a DAO interface that encapsulates these sort of details:

Team.js

teamSchema.statics.findByGroupName = function (gname, cb) {
    this.find({ GroupName: gname }, cb);
};
...

Other.js

Team.findByGroupName(gname, function (err, teams) {
   // Some code
});
