Rails format.xml 渲染并传递多个变量

发布于 2024-11-01 02:22:55 字数 463 浏览 3 评论 0原文

典型用法是：

respond_to do |format|
  format.html # index.html.erb
  format.xml  { render :xml => @users }
end

现在我还想传递一个名为“teststring”的字符串。

参考

:local => {:users => @users, :another => @another}

我已经看到了使用但我不知道如何将两者合并在一起的。我只是还没有看到所有的东西。没有太多文档来真正解释该行中的 :xml 。我不知道是否可以用 :teststring => 处理字符串测试字符串？

最后，既然我有多个变量，我该如何在 index.html.erb 中处理它们？它们是否从渲染命令中以相同的名称传递？

谢谢。

Typical usage is:

respond_to do |format|
  format.html # index.html.erb
  format.xml  { render :xml => @users }
end

And now I want to also pass a string named "teststring".

I've seen reference to using

:local => {:users => @users, :another => @another}

But I don't know how to merge the two together. I just haven't seen everything all together. Not much documentation to really explain the :xml in that line. And I don't know if I can deal with the string with :teststring => teststring?

And lastly, how do I deal with them in my index.html.erb now that I have multiple variables? Do they get passed with the same name from the render command?

Thanks.

如果要呈现自定义 XML，则需要在控制器的相应视图目录中创建一个 index.xml.erb 文件。它的工作方式就像您使用的任何 HTML 模板一样，然后：

app/controllers/home_controller.rb:

def index
    @users = ...
    @another = "Hello world!"

    # this `respond_to` block isn't necessary in this case -
    # Rails will detect the index.xml.erb file and render it
    # automatically for requests for XML
    respond_to do |format|
        format.html # index.html.erb
        format.xml # index.xml.erb
    end
end

app/views/home/index.xml.erb:

<?xml version="1.0" encoding="UTF-8"?>
<document>
    <%= @users.to_xml # serialize the @users variable %>
    <extra_string><%= @another %></extra_string>
</document>

(您可以在此处阅读有关 ActiveRecord 的 to_xml 方法< /a>。）

If you want to render custom XML, you'll need to create a index.xml.erb file in the corresponding view directory for the controller. It works just like any HTML template you'd use, then:

app/controllers/home_controller.rb:

def index
    @users = ...
    @another = "Hello world!"

    # this `respond_to` block isn't necessary in this case -
    # Rails will detect the index.xml.erb file and render it
    # automatically for requests for XML
    respond_to do |format|
        format.html # index.html.erb
        format.xml # index.xml.erb
    end
end

app/views/home/index.xml.erb:

<?xml version="1.0" encoding="UTF-8"?>
<document>
    <%= @users.to_xml # serialize the @users variable %>
    <extra_string><%= @another %></extra_string>
</document>

(You can read about ActiveRecord's to_xml method here.)
