New on the blog: Associations Deep-Dive — hasMany, belongsTo, Nested Properties, and Eager Loading. <https://blog.wheels.dev/posts/associations-deep-dive-wheels-4/ > What it covers: • The three association types (belongsTo / hasMany / hasOne), how Wheels deduces modelName + foreignKey + joinKey from one

name

arg, and when to override them • The exact dynamic methods each one generates —

author.posts()

,

author.postCount()

,

author.addPost()

,

author.deleteAllPosts()

, and the rest — with a table per type •

dependent=

and its five legal values (delete / deleteAll / remove / removeAll / false). There is NO `nullify`; FK-nulling is

remove

/

removeAll

.

belongsTo

has no

dependent

at all. •

nestedProperties

— save a parent and its children from one form submit;

autoSave

defaults true,

allowDelete

defaults false • Eager loading with

include=

to kill the N+1, why nested

include="artist(genre)"

is query-only, has-many-through via

shortcut

, and why a polymorphic belongsTo can't be eager-loaded Plus a Sharp Edges section: getters return QUERIES not arrays, join-type defaults differ by association (belongsTo inner-joins and silently drops parentless rows), and mixed positional+named args error every time.
