Rails：在一个表单中多次提交按钮 [英] Rails: Multi-submit buttons in one Form

问题描述

假设我有一个文章模型，并且在文章'新'视图中，我有两个按钮，发布和保存草稿。

我的问题是我怎么知道哪个按钮在控制器中被点击。

我已经有了一个解决方案，但我认为必须有更好的方法。
我目前在该视图中使用的是：

 < div class =actions> 
<％= f.submit发布％> 
 <％= f.submit保存草稿，：name => 提交％> 
< / div> 
  

所以在控制器中，我可以使用 params [：commit] 字符串来处理该动作。

  def create 
 @article = Article.new（params [：article]）
 if params [ ：commit] ==Publish
 @ article.status ='publish'
 //详细信息省略
结束
 
 @ article.save 
结束
  

但我认为使用视图相关的字符串并不好。你能告诉我另一种方法来完成这个吗？

更新：由于这些按钮的形式相同， '创造'行动，这对我来说没问题。我想要的是在创建操作中处理这些内容，例如为Article模型设置一个状态列并保留公开或草稿。 方案

这已在 Railscast第38集中介绍。使用 params 散列来检测哪个按钮被点击是正确的方法：

查看：

 <％= submit_tag'创建'％> 
 <％= submit_tag'创建并添加另一个'，名称：'create_and_add'％> 
  

控制器：

  if params [：create_and_add] 
＃例如，重定向到新表单。 
 
 else 
＃例如，重定向显示新创建的记录。 
 end 
  

Say I have an Article model, and in the article 'new' view I have two buttons, "Publish" and "Save Draft".

My question is how can I know which button is clicked in the controller.

I already have a solution but I think there must be a better way. What I currently used in the view is:

<div class="actions">
  <%= f.submit "Publish" %>
  <%= f.submit "Save Draft", :name => "commit" %>
</div>

So in the controller, I can use the params[:commit] string to handle that action.

def create
  @article = Article.new(params[:article])
  if params[:commit] == "Publish"
    @article.status = 'publish'
    // detail omitted
  end

  @article.save
end

But I think using the view related string is not good. Could you tell me another way to accomplish this?

UPDATE: Since these buttons are in the same form, they're all going to the 'create' action, and that's OK for me. What I want is to handle that within the create action, such as give the Article model a 'status' column and holds 'public' or 'draft'.

解决方案

This was covered in Railscast episode 38. Using the params hash to detect which button was clicked is the correct approach:

View:

<%= submit_tag 'Create' %>
<%= submit_tag 'Create and Add Another', name: 'create_and_add' %>

Controller:

if params[:create_and_add]
  # Redirect to new form, for example.

else
  # Redirect to show the newly created record, for example.
end
