我需要在 URL 中使用 slugs 而不是文章 ID，所以我在 meanjs 给出的文章示例中更改了一些内容，但我有一个问题，我可以列出、查看和编辑，但我无法创建新的。我不熟悉 MEAN 堆栈，所以我的修改很可能有一些非常错误的地方，但我可以想办法让它工作。
slug 是在创建文章时从标题生成的。我也想被编辑，但如果我把 slug 字段也编辑，编辑功能也会停止工作......
代码来自使用垂直模块的 meanjs 的 0.4 分支。
如果我更改，在文章.client.service.js 中：
angular.module('articles').factory('Articles', ['$resource',
function($resource) {
return $resource('api/articles/:articleSlug', {
articleSlug: '@slug'
}, {
update: {
method: 'PUT'
}
});
}
]);
为了：
angular.module('articles').factory('Articles', ['$resource',
function($resource) {
return $resource('api/articles/:articleSlug', {
articleSlug: '@_id'
}, {
update: {
method: 'PUT'
}
});
}
]);
创建功能开始工作，但编辑功能停止... -.-
任何帮助将不胜感激。谢谢
