This article will explain in detail how Laravel Eloquent returns to the default model object one-to-many. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.

One-to-many returns default model objects

Suppose there is a situation where you want to show the author of an article, and the template code is:

{{ $post->author->name }}

But if the author's information is deleted or not set for some reason. The code returns an error such as "property of non-object."

Of course you can do this:

{{ $post->author->name ?? '' }}

You can do this through Eloquent relationships:

public function author(){ return $this->belongsTo('App\Author')->withDefault();}

In this example, if the text has no author information, author() returns an empty App\Author model object.

Furthermore, we can also assign default values to attributes in default model objects.

public function author(){ return $this->belongsTo('App\Author')->withDefault([ 'name' => 'Guest Author' ]);} About "Laravel Eloquent how to return the default model object one-to-many" This article is shared here, I hope the above content can be of some help to everyone, so that you can learn more knowledge, if you think the article is good, please share it to let more people see.
