Constant REFERENCES 

pub const REFERENCES: ColumnMarker;

Adds a foreign key that references a column of another table.

Examples

#[column(references = User::id)]
user_id: i32,

With the query feature this also generates relation accessors: a forward one on this table, named after the column without its _id suffix (user_id gives .user()), and a reverse one on the referenced table (see RELATION).
