php// Print the SQL statement you are querying to see public function article () {return $ this-> hasexample ('app \ avatar ', 'id ', 'avatars _ id');} public function avatar () {return $ this-> belonsto ('app \ App \ article', 'avatars _ id ', 'id ');}

You can check dd ($ articles). I believe it will be null on relations. It always feels strange to your relationship statement.

Check which variable is output in row 15th, and then print the variable in dd. Solve the problem gradually.

The call Association is incorrect.

avatars_id->url}}" alt="" width="180px">

Use

{{$page->avatar->url}}

Because you are using

$articles = Article::with('avatar')->latest()->paginate(8);

If you want to change the ing name, you must

$ Articles = Article: with (array ('avatars _ id' => function () {/* ing relationship */})-> latest () -> paginate (8 );

After that, you have to change a lot.

Thank you for your answers, but I did it myself.
My solution and the answer I selected are one method.
On
Acticle.phpChanged the content

    public function avatar()    {        return $this -> belongsTo('App\Avatar','avatars_id');    }

That's it. The content associated with the template is
{$ Page-> avatar-> url}
Fields of the model Association Method

Thank you very much. I have also posted a correct solution to my problem.
I hope to provide a solution for my friends who encounter such problems in the future.

In fact, you only need to build tables along the way with convention.avatar_idThis will not cause these problems.

In addition, we recommend that you use the plural value when using the hasMany () relationship.

public function articles() {    return $this->hasMany('App\Article');}

I am also clear about this writing ~
