在 rails 3.2.12 中单击 simple_form 视图中的提交按钮时，有没有办法传递参数? [英] Is there a way to pass params when clicking submit button in simple_form view in rails 3.2.12?

问题描述

在 simple_form 视图中，提交按钮是这样的:

In simple_form view, the submit button is like this:

<%= f.button :submit, 'Save' %>

我们试图在点击 Save 按钮时传递参数 subaction.单击按钮后，params[:subaction] 的值应为更新".这是我们尝试过但没有奏效的方法:

We are trying to pass a params subaction when clicking the Save button. The params[:subaction] should have value of 'update' after clicking the button. Here is what we tried in view but it did not work:

<%= f.button :submit, 'Save', :subaction => 'update' %>

有没有办法在点击 Save 按钮时在 params[:subaction] 中传递一个值?

Is there a way to pass a value in params[:subaction] when clicking the Save button?

推荐答案

使用名称和值选项.

   <%= f.button  :submit , name: "subaction",value: "update"%>

在您的控制器中，您将获得值为update"的 params[:subaction]

In your controller you will get params[:subaction] with the value "update"
