PHP:Laravel如何急于加​​载查找方法 [英] PHP: Laravel how to eager load find method

问题描述

我有一个模型Users，其中有很多Pages，我想急于加载下面的方法，以便它仅返回一个渴望加载所有页面的用户，我该如何处理.

I have a model Users which has-many Pages, I want to eager load the method below so that it returns only a single user with all the pages eager loaded, how do I go about it.

$user = User::find(1);
$pages = $user->pages();
foreach($pages as $page) {
  var_dump($page->name);
}

我尝试但不起作用的内容，而是加载了所有内容:

What I tried but doesnt work, it loads everything instead:

$user = User::with('Pages')->get();
$pages = $user->pages();

推荐答案

删除括号.

$user = User::find(1);
$pages = $user->pages;
foreach($pages as $page) {
    var_dump($page->name);
}

如果您希望加载它，请使用with方法并传递正确的参数，该参数将是您的关系方法的名称:

If you want to eager load it, then use the with method and pass the correct parameter, which would be the name of your relationship methods:

$user = User::with('pages')->find(1);
foreach($user->pages as $page) {
    var_dump($page->name);
}
