在 Yii 中变得未知属性

Question

在那儿的课程内容下，我想让活动栏显示“是”或**“否” **起初它显示“1”或“0”，但这不是我想要显示的。这些是我尝试的代码，我收到了这个错误。如果有人能指导我，我将不胜感激。

Answer 1

必须对您的代码进行 2 处更改。

将所有 $model->isActive 更改为 $model->active。
Return“是”或“否”取决于 $model->active 值。

更新DetailView：

[
    'attribute' => 'active',
    'value' => function ($model) {
        return $model->active ? "Yes" : "No";
    },
    'contentOptions' => ['style' => $model->active ? 'color:green' :'color:red']
],

更新GridView：

[
    'attribute' => 'active',
    'value' => function ($model) {
        return $model->active ? "Yes" : "No";
    },
    'contentOptions' => function ($model, $key, $index, $column) { 
        return $model->active ? ['style' => 'color:green'] : ['style' => 'color:red']; 
    }
],
