我有一些像这样的代码users_controller.rb,我需要打印线30号在development.log是否可以在开发记录器中打印一行?
line#29 def selectrole
line#30 @userrole = RolesUser.find(:all, :conditions =>["p.user_id = ? and p.status = ? ",session[:user_id], params['status']])
line#31 logger.debug print_line(30)
line#32 end
我可以看到30日线在我development.log这样
@userrole = RoleUser.find(:all, :conditions => ["p.user_id = ? and p.status = ? ", 1234, 'Active'])
写“print_line”函数的方法是什么?这是我的print_line代码?
def print_line(file_name, line)
counter = 1
printline = "-------- NO SUCH LINE --------"
File.open(file_name, "r") do |infile|
while (line_text = infile.gets)
if counter == line
printline = "#{counter} :: " + line_text
break
end
counter += 1
end
end
printline
end
从这个功能我越来越喜欢这个
@userrole = RolesUser.find(:all, :conditions =>["p.user_id = ? and p.status = ? ",session[:user_id], params['status']])
是他们没有办法找到与它们各自的值替换变量?
logger.debug “富:#{} FOO”。我建议你使用调试器进行那种测试。它可以完全访问所有变量。 – apneadiving 2011-01-25 07:09:48
