Laravel: how can I loop through the fields and relations of an ORM
提问by jaget
In Laravel if I create an ORM for a table, lets say pages
在 Laravel 中，如果我为表创建 ORM，可以说页面
Is there a way to list/loop through all the tables fields and their values (from the database), and on top of that is there a way to list/loop through all the relationships.
有没有办法列出/循环遍历所有表字段及其值（来自数据库），最重要的是有一种方法列出/循环遍历所有关系。
Is there a way to access the attributes/fields of an orm object such as:
有没有办法访问 orm 对象的属性/字段，例如：
foreach($pages->fields_array as $f){
//do something with field
}
What I'm trying to do is get a dynamic list of fields and their values so I can auto build a form.
我想要做的是获取字段及其值的动态列表，以便我可以自动构建表单。
As for the relations I am trying to loop through all related tables to create a dropdown list of linked tables.
至于关系，我试图遍历所有相关表以创建链接表的下拉列表。

in Laravel 3 you can loop with $page->attributes
在 Laravel 3 中，您可以使用 $page->attributes 循环
But not in Laravel 4.
但不是在 Laravel 4 中。
Just do this instead and do for each after.
只需执行此操作，然后为每个执行此操作。
$page->toArray(); // it will convert the model object into an array :)

Here's how i loop through an object and it's relations (images is the relation for this example)
这是我如何遍历对象及其关系（图像是此示例的关系）
$page = Page::with('images')->first();
// Laravel 4
foreach($page->attributes as $attr)
{
dd($attr);
}
// Laravel 5
foreach($page->getAttributes() as $attr)
{
dd($attr);
}
