Manipulation all model-attributes before the view

Question

Before issuing the "Content" model, I want to search and replace all attributes for placeholders.

I use "tylercd100/laravel-placeholders" to search the placeholders and that works too!

public function processVariables()
    {
        Placeholders::setThorough(false);

        $content = \Route::current()->parameter('id');
        $arrContent = Content::findOrFail($content->id);

        $arrPlaceholders = PlaceholdersTraits::setPlaceholders($arrContent);        
        $variables = Placeholders::parse($arrContent, $arrPlaceholders);

        return $variables;
    }

Unfortunately it does not work for the output and I can not get any further.

here the error message in the ausag:

Trying to get property of non-object

Answer 1

我相信\\ Route :: current（）-> parameter（'id'）返回字符串或整数。

Answer 2

With "Placeholders::parse($arrContent, $arrPlaceholders)" i get a string!

How do I convert the string to the Content-Instance (Content::findOrFail($content->id))?
