Idiorm / Paris - 访问交汇处的列

Question

I'm using Paris for my new project...

Let's say I have 3 tables: users, books and borrows:

users: id/name

books: id/title

borrows: users_id/books_id/borrow_date/return_date

---

In Books class:

function users()
{
    return $this->has_many_through('Users', 'Borrows');
}

In Users class:

function books()
{
    return $this->has_many_through('User', 'Borrows');
}

Everything is fine, I can access to borrowed books by each user and list of users who borrowed a single book before, but I'm wondering that how can I access to borrow_date and return_date column/property of Borrows table/class?

Answer 1

You can do it using Idiorm (the Paris brother).

User model:

<?php
class User extends Model {
    public static $_table = 'Users';
    public static $_id_column = 'id';

    function books()
    {
        return $this->has_many_through('User', 'Borrow');
    }

    public static function findBooksAndBorrows($id) {
        return ORM::for_table('Users')
            ->join('Borrows', array('Users.id', '=', 'Borrows.users_id'))
            ->join('Books', array('Borrows.books_id', '=', 'Books.id'));
    } 
}

In your code:

$booksAndBorrows = User::findBooksAndBorrows(1)->find_array();
echo json_encode($booksAndBorrows);
