Assoc table, composite pk and fk at same time

[suncica2222]

I have association table in mysql that I want to translate into doctrine yaml mappings. List_id and user_id are at the same time composite primary and foreign keys. I'm confused weather I should have in listUserTb entity class both $userId and $user ($listId, $list) fields? Or can id_str from users_tb be automaticaly resolved to user_id in list_user_tb using just $user field in entity class? I've read this article http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/tutorials/composite-primary-keys.html#identity-through-foreign-entities

Basicaly I want to trannslate this sql, I'm also not sure do I need bidirectional association (oneToMany from users_tb and list_tb to list_user_tb) or just manyToOne from ListUserTb is enough?

sql

CREATE TABLE IF NOT EXISTS list_tb (
    list_id               VARCHAR(255) PRIMARY KEY, 
    country               VARCHAR(255) NOT NULL
);

CREATE TABLE IF NOT EXISTS users_tb (           
    id_str          VARCHAR(255) PRIMARY KEY,             
    name            VARCHAR(255) NOT NULL,
    statuses_count  INT(10)      NOT NULL   
);

CREATE TABLE IF NOT EXISTS list_user_tb (
    list_id         VARCHAR(255),
    user_id         VARCHAR(255),
    priority        INT(10)  NOT NULL
    PRIMARY KEY (list_id, user_id)
);

ALTER TABLE list_user_tb 
    ADD CONSTRAINT fk_list_user_tb_list_tb FOREIGN KEY (list_id) REFERENCES list_tb(list_id);

ALTER TABLE list_user_tb 
    ADD CONSTRAINT fk_list_user_tb_users_tb FOREIGN KEY (user_id) REFERENCES users_tb(id_str);

ListUser.yml
