问题 I have a HABTM relationship between a books table and an authors table, joined with an authors_books table. However, I can't find a solution to display the fields firstname, lastname and fullname in my view. book-model: class Book extends AppModel { var $name = 'Book'; var $hasAndBelongsToMany = array( 'Author' => array( 'className' => 'Author', 'joinTable' => 'authors_books', 'foreignkey' => 'book_id', 'associatioanForeignKey' => 'author_id' ) ); author-model: class Author extends AppModel {

Note: The registration and update of the join is correct, only the additional attribute that is not being passed to the table.

问题 I have two models, Clinician and Patient . A clinician has_many: patients and a patient belongs_to :clinician . A third model, SharedPatient is meant to store additional assosiactions between patients and clinicians as a patient can be shared by many other clinicians besides the one it belongs_to . This is done using a has_and_belongs_to_many relationship. See models: class Clinician < ActiveRecord::Base has_many :patients has_and_belongs_to_many :shared_patients, join_table: 'shared_patients
