Question

我想用Yii2 Framework制作一个todo应用程序。我使用了Gii插件并创建了模型，控制器和视图。但是当我在地址栏中键入地址索引的地址时 错误404 发生。

我尝试了所有网址组合，但仍然是同样的错误。所有文件都已正确创建，但我仍无法找到它们。

Answer 1

如果您还没有使用prettyUrl，则应该访问http://localhost/basic/web/index.php?r=gii

Answer 2

确保在web.php中没有注释开发环境。

    //DEVELOPMENT ENVIRONMENT
if (YII_ENV_DEV) {
    // configuration adjustments for 'dev' environment
    $config['bootstrap'][] = 'debug';
    $config['modules']['debug'] = [
        'class' => 'yii\debug\Module',
    ];

    $config['bootstrap'][] = 'gii';
    $config['modules']['gii'] = [
        'class' => 'yii\gii\Module',
    ];
}

return $config;

然后尝试使用： http://localhost/basic/web/index.php?r=gii

Answer 3

填写controller class字段时，您应该小心，因为区分大小写。写app\controllers\...而不是app\Controllers\...。

我认为CRUD Generator表单中的所有字段都区分大小写。

无法访问通过网址从gii创建的CRUD
