How to retrieve all model data from a view in Laravel?
提问by Rajat Saxena
I'm trying to build a widget designing system where a user can submit the title and html of the widget.Now when I try query the Widget model in a view and pass the data to @foreachloop,I get the error as @foreachis not able to iterate over the queryset returned by Widget::all().How can I display all the data from Widget model on my webpage?
我正在尝试构建一个小部件设计系统，用户可以在其中提交小部件的标题和 html。现在，当我尝试在视图中查询小部件模型并将数据传递给@foreach循环时，我收到错误，因为@foreach无法迭代返回的查询集。Widget::all()如何在我的网页上显示来自 Widget 模型的所有数据？
Btw my Widget model has only two fields(i.e title and html).
顺便说一句，我的 Widget 模型只有两个字段（即标题和 html）。
EDIT:Following is the var_dumpof what I get in return when I do Widget::all()
编辑：以下是var_dump我得到的回报Widget::all()
array(2) { [0]=> object(Widget)#42 (5) { ["attributes"]=> array(3) { ["id"]=> string(1) "1" ["title"]=> string(24) "Join Demo classes today!" ["html"]=> string(47) "
This is just the great demo of widgets.
" } ["original"]=> array(3) { ["id"]=> string(1) "1" ["title"]=> string(24) "Join Demo classes today!" ["html"]=> string(47) "
This is just the great demo of widgets.
" } ["relationships"]=> array(0) { } ["exists"]=> bool(true) ["includes"]=> array(0) { } } [1]=> object(Widget)#45 (5) { ["attributes"]=> array(3) { ["id"]=> string(1) "2" ["title"]=> string(12) "About Google" ["html"]=> string(66) "Google is the best site in the world." } ["original"]=> array(3) { ["id"]=> string(1) "2" ["title"]=> string(12) "About Google" ["html"]=> string(66) "Google is the best site in the world." } ["relationships"]=> array(0) { } ["exists"]=> bool(true) ["includes"]=> array(0) { } } }

It's hard to solve your problem without any code. Here's what I would do:
没有任何代码很难解决您的问题。这是我会做的：
controller:
控制器：
$widgets = Widget::all();
View::make('html.widgets')->with('widgets', $widgets);
view (blade):
视图（刀片）：
@foreach($widgets as $widget)
{{ $widget->title }}
{{ $widget->html }}
@endforeach
In the question you're mentioning query the widget in a view. As this is clearly against MVC principles but demonstrates the flexibility of laravel, I will also give you a snippet how one can do that without a controller. I do notrecommend this:
在您提到的问题中，在视图中查询小部件。由于这显然违反了 MVC 原则，但展示了 laravel 的灵活性，我还将给你一个片段，如何在没有控制器的情况下做到这一点。我不建议这样做：
@foreach(Widget::all() as $widget)
{{ $widget->title }}
{{ $widget->html }}
@endforeach
