Rails 3 - 在 respond_to 中设置文件名 [英] Rails 3 - set the filename in a respond_to

问题描述

这看起来应该很简单，但我似乎找不到直接的答案.

This seems like it should be simple, but I can't seem to find a straight answer.

我添加了一个 csv mime 类型，以下似乎有效，除了下载的文件总是命名为report.csv".

I have added a csv mime-type, and the following seems to work, except that the downloaded file is always named "report.csv".

在我的控制器中:

def report
  respond_to do |format|
    format.html
    format.csv do
      render :template => "summary/report.csv.erb",
             :filename => "foo" #doesn't work
    end
  end
end

我认为它使用的是默认渲染器(我还没有实现替代渲染器)，但我似乎无法找到有关可用选项的完整文档.

I think it's using the default renderer (I haven't implemented an alternate renderer), but I can't seem to find complete docs on the options available.

难道没有类似文件名"选项或我可以使用的东西吗?有没有更好的方法?

Isn't there something like a "filename" option or something that I can use? Is there a better approach?

推荐答案

我明白了，感谢 this answer.

format.csv do
  response.headers['Content-Disposition'] = 'attachment; filename="' + filename + '.csv"'
  render "summary/report.csv.erb"
end

首先在响应头中设置文件名，然后调用render.

First you set the filename in the response header, then you call render.

(render 的模板参数是可选的，但在我的情况下我需要它.)

(The template param to render is optional, but in my case I needed it.)
