complex db.get example

var _q={
  model: 'Papers',
  where: {
    $or: [
      {_id: { $in: [0,1,2,3,4,5] }},
      {numbers: { $in: [0,1,2,3,4,5]}}
    ]
  },
  populate: 'cover',
  select: 'cover name cont',
  limit: 10
};
db.get(_q,function(err,papers){
  if(err) done(true,err);
  else{
    done(null,papers);
  }
});

db.get as find

find all models.

var query = {
  model:'modelName'
};
db.get(query, callback(err, res){
  // do something
});

db.get as findById

modelID String

var query = {
  model:'modelName',
  id: modelID
};
db.get(query, callback(err, res){
  // do something
});

db.get - Find by multiple ids.

id accepts an Array of values.

modelID Array or String

var query = {
  model:'modelName',
  where: { _id : { $in : [...] } }
};
db.get(query, callback(err, res){
  // do something
});

db.get as find (passing a where option.)

var query = {
  model:'modelName',
  where: { ... } // list of columns
};
db.get(query, callback(err, res){
  // do something
});

db.create

var _q = {
  model:'Papers',
  body: {
    name:'Important paper.',
    cont:'...'
  }
};
db.get(_q, callback(err, res){
  // do something
});

db.update (it's like using get.)

var _q={
  model: 'Papers',
  where: { name: 'Unnamed paper.' },
  body:{
    name: 'Important paper.'
  },
  limit: 10
};
db.update(_q,function(err,affected){
  done(err,affected);
});

db.update

passing a function

var _q={
  model: 'Papers',
  where: { _id: _id },
  body:function(model,opts,cb){
    // model - the model.
    // opts - this same _q object.
    // cb - callback for complete.
    // this - model schema.
    model.update({
      // update 1
    },{
      // update 2
    });
  }
};
db.update(_q,function(err,affected){
  done(err,affected);
});

db.destroy (it's like using get.)

var query = {
  model: 'modelName',
  where: { _id: _id }
};
db.destroy(query, callback(err, res){
  // do something
});
