Rails路由与IE一样糟糕 [英] Rails routing is being wonky with IE

问题描述

想要使用jQuery，Orbited和FasterCSV，我制作了一个Rails聊天应用程序。

Wanting to play with jQuery, Orbited, and FasterCSV, I made a Rails chat application.

您可以浏览到一个URL，并且有一个类似于IRC的聊天窗口。您还可以通过访问相同的URL导出聊天窗口的内容，但为URL添加.csv扩展名。

You can browse to a URL and there is a chat window that is similar to IRC. You can also export the contents of the chat window by visiting the same URL but adding a ".csv" extension to the URL.

HTML版本： http://host.name/channel/sweetchatroom

CSV版本： http://host.name /channel/sweetchatroom.csv

在Firefox，Safari和Chrome中，它正常工作。在IE中，如果我访问HTMLURL，则会获得该页面的CSV版本。我必须手动将.html添加到URL中，如下所示：

In Firefox, Safari, and Chrome it works normal. In IE, If I visit the "HTML" URL, I get the CSV version of the page. I have to manually add ".html" to the URL like so:

http://host.name/channel/sweetchatroom.html

我的路线目前看起来像这样：

My route currently looks like this:

map.chat '/channel/:name.:format', :controller => 'channels', :action => 'show'

我用Google搜索并尝试了以下建议：

I Googled a bit and tried the following suggestions:

map.slug '/channel/:slug.:format', :controller => 'channels', :action => 'show', :defaults => {:format => 'html'}

- 和 -

map.slug '/channel/:slug.:format', :controller => 'channels', :action => 'show', :format => 'html'

它们都没有奏效。显然，如果您在未指定格式的情况下访问URL，则Rails不会将 params [：format] 设置为任何内容。原则上我更喜欢这个，但是文档很清楚，你可以设置一个默认格式，我不知道为什么它不尊重这个。 ：defaults => ...建议就是Rails文档中的内容。

Neither of them worked. Apparently, if you visit a URL without specifying the format, Rails does not set params[:format] to anything. Which in principle I prefer, but the docs are pretty clear that you can set a default format and I'm not sure why it doesn't honor this. The ":defaults => ..." suggestion is what is in the Rails docs.

为了让它工作，我不得不改变我的部分渠道控制器：

In order to get it to work I had to change this part of my channels controller:

respond_to do |format|
  format.csv { 
    send_data channel_to_csv(@channel),
      :type => "text/plain",
      :filename => "#{@channel.slug}.csv",
      :disposition => 'inline'
  } 
  format.html # show.html.erb
  format.xml  { render :xml => @channel }
end

到此：

respond_to do |format|
  format.csv { 
    send_data channel_to_csv(@channel),
      :type => "text/plain",
      :filename => "#{@channel.slug}.csv",
      :disposition => 'inline'
  } if params[:format] == 'csv' # <-- Here is the change
  format.html # show.html.erb
  format.xml  { render :xml => @channel }
end

它运作完美但看起来真的很乱。必须有更好的，更红宝石的方式。我的路线条目上的语法有误吗？似乎路线应该是这样的。

It works perfectly but seems really hackish. There has to be a better, more "Ruby" way. Do I have the syntax wrong on my routes entry? It seems like routes is where this should be.

我知道我必须遗漏一些东西。我无法在Google或StackOverflow上找到有关此问题的良好信息。这通常意味着我已经走出了杂草。

I know I have to be missing something. I couldn't find good information on this problem on Google or on StackOverflow. That generally means I'm way out in the weeds.

推荐答案

我通常只把format.html放在第一位。这样，当IE发送一个奇怪的接受标题（如 * / * ）时，它不会被搞砸。基本上，如果IE说它接受了所有内容（比如URL上没有扩展名），Rails会发送第一个匹配的东西。

I usually just put the format.html first. That way, when IE sends a weird accepts header (like */*), it doesn't get fouled up. Basically, if IE says it accepts everything (like when there is no extension on the URL) Rails will send it the first thing that matches.
