仅对某些资源覆盖ActiveAdmin资源控制器 [英] Override ActiveAdmin resource controller for only some resources

问题描述

在我的应用程序中，一些资源需要符合hippa规范，并且我们会做一些符合此需求的事情-使用ActiveAdmin :: Comments作为一种git注释系统，并在没有过滤的情况下隐藏索引集合已应用等.

In my app, some of the resources need to be hippa compliant and we do some things to fit in with that need - using ActiveAdmin::Comments as a sort of git commenting system, and hiding the index collection if there's no filtering applied, etc.

所有的河马资源都完全以普通的ActiveAdmin.register [资源]形式编写，因此，我希望有一种方法可以覆盖基本资源，而不是将代码多次剪切并粘贴到每个资源上.控制器，然后将这些特定资源从HippaResource而不是基础资源中提取出来?还是有一种方法可以扩展或包括所使用的通用代码?

All the hippa resources are written totally generically within the normal ActiveAdmin.register [resource] -- so rather than cutting and pasting the code multiple times to every resource, I was hoping there was a way for me to override the base resource controller elsewhere and then have these specific resources pull from the HippaResource rather than the base? Or is there a way to extend or include the generic code used?

推荐答案

好吧，我将再次回答自己的问题-坦白地说，即使我弄清楚了"，我也是确定必须有一种更简单的方法.

Well, once again I'm going to answer my own question - though to be honest, even though I 'figured it out', I'm sure there must be an easier way to do it.

基本上，我在config/initializers/active_admin.rb中编写了我想要的覆盖-通常会覆盖已经存在的资源控制器，但这不是我想要的-我想要 some hippa举足轻重的resource/resource_controllers以某些方式起作用-隐藏数据的任何索引页，仅在过滤后显示.

Basically I wrote the overriding I wanted within the config/initializers/active_admin.rb -- which would normally override already existing resource controllers, but that wasn't what I wanted - I wanted some hippa commpliant resource / resource_controllers to act in certain ways - to hide any index page of data and only display after being filtered.

当使用ActiveAdmin.dialog单击删除"链接或按钮时，我什至可以执行删除/弹出"对话框以输入注释.如果您在上方查看，我将 delete_link 类更改为 hippa_delete_link 类，该类将由以下其他JavaScript提取:

I was even able to do the delete / popup dialog box to enter in a comment when the 'delete' link or button was clicked by using the ActiveAdmin.dialog. If you look above I changed the delete_link class to a hippa_delete_link class which would be picked up by this additional javascript:

(function() {
  $(document).on('ready page:load turbolinks:load', function() {
    $('.hippa_delete_link').click(function(e) {
      var message;
      e.stopPropagation();
      e.preventDefault();
      if (message = $(this).data('confirm')) {
        return ActiveAdmin.modal_dialog(message, $(this).data('inputs'), (function(_this) {
          return function(inputs) {
            return $(_this).trigger('confirm:complete', inputs);
          };
        })(this));
      } else {
        return $(this).trigger('confirm:complete');
      }
    });
    $('.hippa_delete_link').on('confirm:complete', function(e, inputs) {

        var url = this.href;

        $.ajax({
            data: inputs,
            url: url,
            type: "DELETE"
        });
    });
  });

}).call(this);

这是通过{注释:文本输入"}哈希传递到delete方法.

What this does is pass along a {comment: "Text input"} hash to the delete method.
