GridView中的ActionColumn的template可以根据状态显示不同 [ 2.0 版本 ]

最终想实现上图效果。
根据状态的不同，可选的操作不同。
我写的逻辑如下图，但是总报错。说是object 转化string 有问题，但是这样写的template的类型是 string

'template' => function ($model) {
                    $temp = [
                        '0' => '{view:view} {update:update} {delete:delete} {show:show}',
                        '1' => '{view:view} {update:update} {delete:delete} {hide:hide}',
                        '2' => '{view:view} {delete:delete}'
                    ];
                    return $temp[$model->state];
                },

我在接口上看template的定义

The template used for composing each cell in the action column. Tokens enclosed within curly brackets are treated as controller action IDs (also called button names in the context of action column). They will be replaced by the corresponding button rendering callbacks specified in $buttons. For example, the token {view} will be replaced by the result of the callback buttons['view']. If a callback cannot be found, the token will be replaced with an empty string.

As an example, to only have the view, and update button you can add the ActionColumn to your GridView columns as follows:

写的问题在那哪里呢，还是不可以实现的啊
