List of all models

[buschtoens]

Working with mongoose.models is meh. What about mongoose.model() returning an array of all model names like:

var modelNames = mongoose.model() // ["Cars", "Drivers", "Pedestrians"]
  , models = modelNames.map(function(modelName) {
      return mongoose.model(modelName);
    });

That would break every app using mongoose. I find it odd that the application itself wouldn't know which models it created.

[buschtoens]

Uhm, would it? mongoose.model() used to throw Error: Schema hasn't been registered for model "undefined" at you. Apps that would rely on this behaviour are IMHO pretty weird.

In my app I use some homebrew Model loader, which regards dependecies. For that it checks which models have yet been loaded (currently mongoose.models.hasOwnProperty(model)). I know that I could build my own array with all loaded Model names, but why not let Mongoose do the work?

[aheckmann]

Oh you're right, I misunderstood.

Models are cached in different ways, for example, if calling mongoose.model its cached at the mongoose level else if calling connection.model its cached at the connection level. Also, you can call x.model() and specify a different collection name as the original which returns the "same" model but subclassed to use the different collection.. so its not a "clean" thing. More of an implementation detail I'd rather not expose.

[buschtoens]

Okay, so you would rather prefer a homebrew trycatch?

function hasModel(namespace, name) {
  try {
    namespace.model(name);
  } catch(e) {
    return false;
  }
  return true;
}

console.log(hasModel(mongoose, "Model"));
console.log(hasModel(connection, "Model"));

[aheckmann]

You convinced me.

Kudos!

lib/index.js:328 will opts have a future use ({ includeConnections: true })?

[aheckmann]

oops, no.
