mongodb - Mongoose query where value is not null -

looking folling query:

entrant     .find       enterdate : onemonthago       confirmed : true     .where('pincode.length > 0')     .exec (err,entrants)-> 

am doing clause properly? want select documents pincode not null

you should able (as you're using query api):

entrant.where("pincode").ne(null) 

... result in mongo query resembling:

entrants.find({ pincode: { $ne: null } }) 

a few links might help:

• the mongoose query api
• the docs mongo query operators
