Migration/Setup Facilities

[MichaelXavier]

I'm looking into writing an adapter for IndexedDB. One of the technical hurdles is that IndexedDb has a setup process wherein the local database is mirated and indexed. I wanted to know if you guys had any opinions or ideas on how data-core could accommodate database configuration and migration. I figure migration would need to receive the complete set of models so it could query their structures, create the appropriate indices, etc.

At the moment, I don't think this is a good fit for core. However, we have recently added a number of introspection facilities to models that should make a migration facility possible.

Most importantly:

var attributes = Ember.get(Person, 'attributes');

attributes.forEach(function(name, metadata) {
  // metadata contains `type` and `key`
  // it will probably contain more in the future
});


var associations = Ember.get(Person, 'associations');

associations.forEach(function(type, list) {
  list.forEach(function(metadata) {
    // metadata contains `name` and `kind`
  });
});

We'd be happy to host a migration solution in the ember organization, and I'd be happy to help you with any further APIs you need or to review the code.

Please email me at wycats@gmail.com if you have something to look at (or if you have general questions about migrations) and open a new ticket if you need some other API from Ember.
