csv文件的send_data返回文件的文本,而不是文件

Question

美好的一天!我想下载自动生成的文件qwerty.csv,但它只返回文本"12345"(没有文件).你能帮助我吗？

UI

<script type="text/javascript">
function getCsv() {
    var ids = getSelectedRecordIds();
    $.post('/payments/form_csv.csv', { ids: ids }, function(data) {});
}
</script>

调节器

def form_csv
    csv_string = CSV.generate do |csv|
        csv << ["12345"]
    end

    respond_to do |format|
        format.csv {
            send_data csv_string, :type => 'text/csv; charset=utf-8; header=present', :disposition => "attachment; filename=qwerty.csv", :filename => "qwerty.csv"
        }
    end
end

在控制台中

Started POST "/payments/form_csv.csv" for 127.0.0.1 at 2012-06-18 18:18:11 +0400 
Processing by PaymentsController#form_csv as CSV
  Parameters: {"ids"=>["18\n\t  "]}
  Rendered text template (0.0ms)
Sent data qwerty.csv (0.4ms)
Completed 200 OK in 2ms (Views: 0.4ms | ActiveRecord: 0.0ms)

但是没有文件提示......

Ow,它没有ajax,作为表单提交工作!

该主题存在同样的问题:http: //www.ruby-forum.com/topic/111107

使表单成为非AJAX表单我尝试它...它的工作原理!

调节器

def form_csv
    csv = get_csv
    send_csv(csv)
end

def get_csv
    result = CSV.generate do |csv|
        csv << ["12345"]
    end
    return result
end

def send_csv(csv)
    send_data csv, :type => 'text/csv; charset=utf-8; header=present', :disposition => "attachment; filename=payments.csv"
end

UI

function getCsv() {
    var ids = getSelectedRecordIds();
    params = {ids: ids}
    post_to_url("/payments/form_csv", params);
}

其中post_to_url - 来自JavaScript post请求的方法, 如表单提交 主题.

毕竟

protect_from_forgery :except => :form_csv

在控制器中禁用pay_csv请求的身份验证令牌.

丑陋的决定,但它有助于我......可能有更正确的方法吗？

Viren,我会试一试,谢谢!
