如何在不显示 ID 号的情况下使用 Yii2 Sluggable Behavior？

Question

I have read the question on using SluggableBehavior in Yii2

and in my trial case I can generate url like article/1/First-Article using the rule in urlManager

'article/<id:\d+>/<slug>' => 'article/view',

and using

\yii\helpers\Url::to(['article/view', 'id'=>$model->id, 'slug'=>$model->slug])

to create url.

In my real case, I use ['article/view', 'hash'=> $model->hash, 'slug'=>$model->slug] to generate url. My rule is

'article/<hash:[\d-\w]+>/<slug>'=>'article/view'

My url is like article/1e482d69129d760e9494b2c6e86eba2b/First-Article.

I want to only show url like article/First-Article, ie not showing the hash code in the url. Is there a way to achieve this? Thanks a lot!

According to Yii docs , if your specify SluggableBehavior 's attribute property with an array of model attributes, it will implode (concatenate) them in order to generate uniqueness for the slug. In your case, this implementation perfectly satisfies your desired slug concatenated composition (eg First-Article-1 );

Internally SluggableBehavior will perform it's generateSlug method to generate unique slug from your attributes composition defined in attribute property.

Since generateSlug uses - delimiter by default, it perfectly fits your requirements in order to generate desired url slug.

Take a look into this:

public function behaviors() 
{   
     return [
         [
             'class' => SluggableBehavior::className(),
             'attribute' => ['slug', 'id'],
             ...
         ]
     ];
}

EDIT:

This is your URL Rule: 'article/<slug>' => 'article/view'

and

Generating appropriate link: Url::to(['article', 'slug' => $model->slug. '-'. $model->id])
