Question

尝试使用https://github.com/RallyTools/Rally-User-Management处的user_permissions_summary.rb脚本同时提取项目层次结构以及用户权限。以下代码添加在 go_user_permissions_summary.rb 中以包含ProjectPath：

def find_path(name,rally,workspaceRef)
  puts "Finding Path... -> #{name}"
  query = RallyAPI::RallyQuery.new()
  query.workspace = {"_ref" => workspaceRef}
  query.fetch = "Parent"
  query.type = :project
  query.query_string = "(Name = \"#{name}\")"   
  results = rally.find(query)

  if results[0].Parent == nil
    path = name
  else
    path = [ find_path(results[0].Parent,rally,workspaceRef), name ].join('/')
  end

  return path
end

使用以下行将ProjectPath列添加到输出：

project_path = find_path(strip_role_from_permission(this_permission.Name),@rally,workspace_obj._ref)

user_permissions_summary.rb运行正常一段时间，然后失败并出现以下错误：

有关解决此问题的任何提示吗？

Ramaprakash，

查询可能无法返回任何结果。由于此情况没有错误检查，因此失败并显示<main> ' undefined method []' for nil:NilClass错误。

有必要进行一些进一步的错误检查或处理其他情况。

类似的东西：

if results.length > 0 && results[0].Parent == nil
    path = name
elsif results.length > 0  
    path = [ find_path(results[0].Parent,rally,workspaceRef), name ].join('/')
else
    path = "Unknown"
end

应该有所帮助。
