Many to many relation in one model

Rails
1

Hi you all,

I have a model called Property where a property is related with many
properties.
I was gonna deal with this by having a has-and-belongs-to-many relation
but… what should I write in the SQL database? Would it be a
“properties_properties” table? And the attributes? :S

Thanks.

This is called a self-referential association. If you Google for “rails
self-referential” you’ll get a lot of useful stuff.
