Rails和jQuery产生406错误

我在使用jQuery提交表单时遇到了406 Not Acceptable错误。我尝试了在网上找到的常见修复程序：Rails和jQuery产生406错误

jQuery.ajaxSetup({ 
    'beforeSend': function(xhr) { 
    xhr.setRequestHeader("Accept", "text/javascript"); 
    } 
})

这并没有解决问题。 request.format输出text/html。我一整天都在试图解决这个问题。 Rails 2.3.4，jQuery 1.3.2和jQTouch。

这里是我的jQuery代码：

jQuery(function() { 
    $("#search").submit(function (e) { 
    var $form = $(this); 
    return app.search($form); 
    }); 
}); 

var app = { 
    search:function ($form) { 
    $.ajax({ 

     type:$form.attr("method"), url:$form.attr("action"), 
     dataType:"script", data:$form.serialize(), 
     complete:function (req) { 
     if (req.status === 200 || req.status === 304) { 
     } else { 
      alert("There was an error searching. Try again."); 
      console.log(this); 
     } 
     } 
    });  
    return false; 
    } 
};

形式：

%form{:action => "/search", :method => "post", :id => "search", "accept-charset" => "utf-8"} 
    %div{:style =>"margin:0;padding:0;display:inline" } 
     %input{:name => "_method", :type => "hidden", :value => "put"} 
     %input{:name => "authenticity_token", :type => "hidden", :value => "#{form_authenticity_token}"} 
    %ul.rounded 
     %li 
     %input{:name => 'query', :value => '', :type => 'text', :placeholder => "Search"}

控制器代码：

def show 
    query = params[:query] 
    @results = Person.search(query) 
    respond_to do |wants| 
     wants.html { } 
     wants.js 
    end 
    end

展示动作是一个叫。我已经验证，这里是日志

正确的方法是编辑（或新增）config/initializers/mime_types.rb接受:iphone请求。

Mime::Type.register_alias "text/javascript", :iphone

好吧，我发现我的问题。我正在使用rails的jqtouch插件，它会自动为开发模式中的请求分配一个：iphone格式，这会迫使我没有的format.iphone。我用这个代码重写：

if request.xhr? && request.format == :iphone 
    request.format = :js 
end
