Struct Association 

pub struct Association {
    pub name: String,
    pub kind: AssociationKind,
    pub foreign_key: String,
    pub table: String,
}

A resolved association: its name plus the conventional foreign key and table.

Fields

name: String

kind: AssociationKind

foreign_key: String

table: String

Implementations

impl Association

pub fn belongs_to(name: &str) -> Self

belongs_to :author — this table holds author_id; target is authors.

pub fn has_one(owner: &str, name: &str) -> Self

has_one :profile on owner — child table holds {owner}_id.

pub fn has_many(owner: &str, name: &str) -> Self

has_many :comments on owner — child table holds {owner}_id. The association name is already plural, so it is singularized before tableizing.

pub fn has_and_belongs_to_many(name: &str) -> Self

has_and_belongs_to_many :tags — target table tags, join FK tag_id.
