Rails - 使用复选框选择多个对象并选择要执行的操作 [英] Rails - Using checkboxes to select multiple objects and having a choice of actions to perform

问题描述

Id希望能够为对象列表创建复选框。然后向用户提供对所选对象执行的多个操作。也就是说删除，存档等。

Id like to be able to create checkboxes for a list of objects. Then offer the user a number of actions to perform on the objects selected. I.e. delete, archive etc.

我知道ryan的screencasts，但它不解释如何创建指向所选对象的多个动作的链接。

I know of ryan's screencasts but it doesnt explain how to create links to multiple actions for the selected objects. It just showed him create a form_tag with a url to one action and a submit button.

推荐答案

我认为你可以做到这一点两种方式。

I think you can do it in two ways.

首先：您可以在一个表单中添加任意数量的按钮：

First: you can add as many buttons to one form as you want:

<%= f.submit "Action 1" %>
<%= f.submit "Action 2" %>
<%= f.submit "Action 3" %>

所有这些都提交到一个操作，您可以在其中检查：

And all of them are submitted to one action in which you can check:

if params[:commit] == "Action 1"
  do some stuff for action 1
elsif params[:commit] == "Action 2"
  do other stuff
... and so on
end

另一种方法是使用一些js。例如，当用户点击按钮操作2时，它会更改表单中的操作参数并将数据提交到此操作。

Another way is to use some js. On example when user clicks on button "Action 2" it changes "action" parameter in form and submits data to this action.

编辑：
您可以这样做：

In case of translated websites, you can do it like this:

<%= f.submit (I18n.t :action_1) %>

和控制器中：

if params[:commit] == I18n.t :action_1
...
end

并在en.yml中添加：

And in en.yml add:

action_1: Action 1

在pl.yml中添加：

In pl.yml add:

action_1: Akcja 1

等等。
