Many 'tags' relations

[Alex Bern]

Is this possible to attach behavior twice or more? For example imagine that base model "post" has more than one 'tags' relation. It can be "tags", "materials", "locations", "dates" etc.

[Alexander Kochetov]

Yes, its possible.

@creocoder how to pls?

[Alexander Kochetov]

@usualdesigner Just set up behavior twice with different ids, like:

public function behaviors() {
    return [
        'taggable1' => [
            'class' => TaggableBehavior::className(),
        ],
        'taggable2' => [
            'class' => TaggableBehavior::className(),
        ],
    ]
}

[Alex Bern]

In this case there should be ability to overwrite $_tagValues property, isn't it? In my I have two similar relations: tags and materials. They have similar functionality (should works the same). So I need methods like 'getMaterialValues()', 'setMaterialValues()' etc. Is this possible to resolve my objective?

[Alexander Kochetov]

@usualdesigner When you attach same behavior twice it work independently. So you do not need override anything, etc. It will work as it is.

[Alex Bern]

Okay. I've defined two relation:

    public function behaviors()
    {
        return [
            'taggable' => [
                'class' => TaggableBehavior::className(),
                'tagRelation' => 'tags',
                'tagValueAttribute' => 'title',
            ],
            'materialable' => [
                'class' => TaggableBehavior::className(),
                'tagRelation' => 'materials',
                'tagValueAttribute' => 'title',
            ],
        ];
    }

Likewise my model has the relations below:

public function getTags()
    {
        return $this->hasMany(Tag::className(), ['tag_id' => 'tag_id'])
            ->viaTable('{{%items_tags}}', ['item_id' => 'item_id']);
    }

    public function getMaterials()
    {
        return $this->hasMany(Material::className(), ['material_id' => 'material_id'])
            ->viaTable('{{%items_materials}}', ['item_id' => 'item_id']);
    }

How in this case I can define tags and materials? I can define tags like this:

$item = new Item();
$item->tagValues = 'one, two, three';

But I can't define materials.

[Alexander Kochetov]

@usualdesigner Example:

$item = new Item();
$item->getBehavior('taggable')->tagValues = 'one, two, three';

$item = new Item();
$item->getBehavior('materialable')->tagValues = 'one, two, three';

[Alex Bern]

Many thanks. That's works.

Another question related to other:

if I have two 'taggable' behaviors in my model - how to use 'relatedByTagValues()' and others similar functions? What if I need to filter by tags and by materials in my own case?

[Zareh]

how can access multi behavior in view ?
i use selectize widget and it is worked but when want to add another widget dont know how access it becuse tagValues is uniqe
`

field($model, 'tagValues')->widget(dosamigos\selectize\SelectizeTextInput::classname(), [ 'loadUrl' => '/tag/list', 'options' => [ 'placeholder' => Yii::t('app', 'Add Tags'), 'class' => 'form-control', ], 'clientOptions' => [ 'persist' => false, 'plugins' => ['remove_button'], 'create' => true, 'maxItems' => 3, 'valueField' => 'name', 'labelField' => 'name', 'searchField' => ['name'], ], ])->hint('Use commas to delimit zip codes')->label(Yii::t('app', 'Category')); ?>
