Add associations

[seancribbs]

Types:

• Simple links
• Embedded
• Complex/custom links (?)

[MarkBennett]

How would you imagine this working? Would you use links between the associated objects?

[seancribbs]

Yes, they will be links, in both directions.

I finished the proxy stuff and sent you a pull request, I might add some basic stuff later.

[Tuxie]

Will you be able to add all association types of ActiveRecord (has_one, has_many, has_many :through, belongs_to and has_and_belongs_to_many) or are some of them not possible?

[bbhoss]

Feature parity with activerecord is not one of the goals of ripple. Riak is quite different from relational databases so we shouldn't try to use old ideas on a new product. We will add relationships/associations where it makes sense.

[seancribbs]

To be clear, there are 2 types and 2 cardinalities of relationships possible, making 4 total classes of relationships:

• One, embedded
• Many, embedded
• One, linked
• Many, linked

There are also some slight variations on these, like "polymorphic" relationships, but the difference is minor.

There are other things to be added to associations, but the basics are there. Let's open more detailed issues for those features.
