我正在使用rails 3.2.22和ruby 2.2。
我正在创建一个文本文件,我想使用send_to发送下载文件。我的代码按预期工作,但每次我点击该操作时,都会在我的应用程序根文件夹中创建该文件的本地副本。我不想要这个,文件应该直接去下载文件夹。我做错了吗?
def save_trunk_logs
data = ""
file = "test.txt"
trunk_logs = some data
File.open(file, "w") do |aFile|
aFile.write("Trunk Name : #{trunk_name}\n")
aFile.write("*"*100)
aFile.write("\n")
aFile.write("Time Stamp"+"\t"+"Log Message\n")
trunk_logs.each do |msg|
text =format_log_messages msg
data << "#{data}\n"
end
end
send_file file, :type => 'application/text; charset=UTF-8', :disposition => 'attachment'
end
感谢任何帮助。

试试这个。
def save_trunk_logs
data = ""
io = StringIO.new
trunk_logs = some data
io.write("Trunk Name : #{trunk_name}\n")
io.write("*"*100)
io.write("\n")
io.write("Time Stamp"+"\t"+"Log Message\n")
trunk_logs.each do |msg|
text =format_log_messages msg
data << "#{data}\n"
end
send_data io.string, :type => 'application/text; charset=UTF-8', :disposition => 'attachment'
end
