Mongoose Guide-Model

Compile your first model

var xxschema = new Schema ({name: ' string ', Size: ' String '}), var Tank = Mongoose.model (' Tank ', Schema);

Construct document

Document is an example of model. Creating updated document to data is easy

var Tank = Mongoose.model (' Tank ', Tankschema), var small = new Tank ({size: ' small '}), Small.save (function (err) {    if ( ERR) return Handlererror (err);    Saved});//ortank.create ({size: ' small '}, function (err, small) {  if (err) return Handlererror (err);  Saved}}

Inquire

Model integrates several built-in static query methods, such as Find, FindByID, FindOne, where

Tank.find ({size: "small"}). WHERE ("CreatedDate"). GT (Oneyearago). exec (callback);

Delete

Model integrates the static Remove method

Tank.remove ({size: ' large '}, function (err) {   if (err) return HandleError (err);   removed;}),

Update

Each model has its own Update method, this method only updates without returning the model, if you like to return to model after updating using findoneandupdate
