Calling Model->Method() within blade templates
提问by Mcg1978
I asked this on the Laravel 4.x forum and tried to find the answer on Google without any luck.
我在 Laravel 4.x 论坛上问过这个问题，并试图在没有任何运气的情况下在 Google 上找到答案。
I'm using Eloquent to load a bunch of user objects that have a created_atproperty. The default MySQL timestamp isn't very readable, so I thought it would be neat to add a readableDate()method to my User model which would output the value as "1 minute ago", "2 days ago" instead.
我正在使用 Eloquent 加载一堆具有created_at属性的用户对象。默认的 MySQL 时间戳不是很易读，所以我认为readableDate()向我的 User 模型添加一个方法会很好，该方法将输出值作为“1 分钟前”、“2 天前”。
When I call on the method in my blade templates like: $user->readableDate()I get the desired output but my whole layout is broken.
当我调用刀片模板中的方法时，例如：$user->readableDate()我得到了所需的输出，但我的整个布局已损坏。
Is it, or should it be possible to call on a model method from within a template?
是还是应该可以从模板中调用模型方法？

If you're using Laravel's Eloquent models, you do not need to add custom methods for handling dates. By default, date fields such as created_atand updated_atare handled as a Carbon objects, which allows you to display the date in a human readable format:
如果您使用 Laravel 的 Eloquent 模型，则无需添加自定义方法来处理日期。默认情况下，诸如created_at和 之updated_at类的日期字段作为Carbon 对象处理，这允许您以人类可读的格式显示日期：
{{ $user->created_at->diffForHumans() }}
You can add additional date fieldsto your Eloquent model with the getDates()method.
您可以使用该方法向 Eloquent 模型添加额外的日期字段getDates()。

Yes, blade is compiled to PHP. :)
是的，blade 已编译为 PHP。:)
You just have to:
你只需要：
Pass your user to your view:
将您的用户传递给您的视图：
return View::make('showUser')->with('user', $user);
And then use it:
然后使用它：
<hml><body>
Last update: {{ $user->readableDate() }}
</body></hml>

ok, I figured this out. What I was trying to do is possible but it was throwing an error that I couldn't see. When I viewed the source of the page the usual laravel error HTML was below my output. The error was being thrown by default values in the created_at field.
好的，我想通了。我试图做的事情是可能的，但它抛出了一个我看不到的错误。当我查看页面的源代码时，通常的 Laravel 错误 HTML 低于我的输出。该错误是由 created_at 字段中的默认值引发的。

Can I assume you are wrapping it inside blade tags {{ code here }}, or did you miss that part?
我可以假设您将它包裹在刀片标签 {{ 此处为代码 }} 中，还是您错过了那部分？
Also, your model should be called using the static approach like this:
此外，您的模型应该使用静态方法调用，如下所示：
{{ User::readableDate() }}
