You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: associations.rs
    path of file: ./repos/diesel/diesel_tests/tests
    
    the code of the file until where you have to start completion: use crate::schema::*;
use diesel::*;

#[test]
fn one_to_many_returns_query_source_for_association() {
    let (mut connection, sean, tess, _) = conn_with_test_data();

    let seans_posts = posts::table
        .filter(posts::user_id.eq(sean.id))
        .load::<Post>(&mut connection)
        .unwrap();
    let tess_posts = posts::table
        .filter(posts::user_id.eq(tess.id))
        .load::<Post>(&mut connection)
        .unwrap();

    let found_posts: Vec<_> = Post::belong
    
fn one_to_many_returns_query_source_for_association() {
    let (mut connection, sean, tess, _) = conn_with_test_data();

    let seans_posts = posts::table
        .filter(posts::user_id.eq(sean.id))
        .load::<Post>(&mut connection)
        .unwrap();
    let tess_posts = posts::table
        .filter(posts::user_id.eq(tess.id))
        .load::<Post>(&mut connection)
        .unwrap();

    let found_posts: Vec<_> = Post::belonging_to(&sean).load(&mut connection).unwrap();
    assert_eq!(seans_posts, found_posts);

    let found_posts: Vec<_> = Post::belonging_to(&tess).load(&mut connection).unwrap();
