Can I define a default value for ember-data model attributes?

Question

When I define an attribute for a model in ember-data, can I specify a default value?

The ember-data model definition suggests attributes are defined like this:

attributeName: DS.attr('number') 

...with an optional second argument as an options hash. I've looked at the code but my code-reading skills aren't up to figuring out what attributes I can put in the options hash. Is it possible to do something like this?

attributeName: DS.attr('number', { default: 0 }) 

or

attributeName: DS.attr('boolean', { default: false }) 

?

Answer 1

You were close, it's defaultValue, see attributes.js#L63-65.

Answer 2

defaultValue doesn't work if the property is null. It only works for 'undefined' attributes. See this
