从数据库获取最新版本的帖子

Question

I am creating a blog where users can post and other users can edit there posts.

When someone edits a post the version should be updated and saved, this works.

Now I want to display only the latest version to the readers.

Not 100% sure how this should work.

I created a function within the model that would select the version based on a simple MAX query. Here is the model:

public function getlatestversion(){
        $lastest = DB::table('contentPost')->max('version');

        return $this->$lastest;
    }

My Blade View:

Partial:

 {{ Str::limit($post->content_posts()->getlatestversion()['content'], 140) }} 

Can I use this directly in my blade view? Or should it also be in my controller? The error that I get is:

"Call to undefined method... getlatestversion()"

Does it have something to do that it is not in my controller, or am I passing it the wrong way?

Thanks

Answer 1

You are obviously in a context, where your method content_posts() does not retrieve a working reference to an object featuring the getlatestverison() method.

Try printr()-ing the result of $post->content_posts() - this might give you a precise hint why you cannot access your method.
