relations about openrecord

[PhilWaldmann]

I'm currently working on getting the docs complete.

You could do the following:

Model.join('athlete') //for a left join - or use .leftJoin(), rightJoin(), .innerJoin() or .outerJoin()

if you just want to prefetch relational data, use .include().

The arguments for .join() and .include() could be a:

• String (relation name)
• Array with relation names
• Object where the key is the relation name. The value could by anything the .include() method accepts (String, Array, Object) - sub relations!

See includes-test.js

so there's no method to fetch an association after the parent is loaded?

e.g. the example above model is 'Account' in the following (obviously unnecessary as is, but shows more of what i'm looking at) example:

Account.get(MY_ID).exec().then((account) => account.athlete.load())

or

Account.get(MY_ID).exec().then((account) => account.relations.athlete.load())

[PhilWaldmann]

With a has_many relation, you could do the following:

Account.get(MY_ID).exec()
.then((account) => account.athletes.exec())
.then(athletes => console.log(athletes))

This currently only works with has_many and belongsToMany, because the relation object (empty array) has all conditions at hand. It's a preconfigured query like Athlete.where({account_id: 1234}).
belongs_to relations return null for a record that isn't prefetched.

I've some ideas to solve this problem. But this is a breaking change, so another thing to address in v2
