使用地图时，Ruby的代码更加透明和简洁

Question

我有一个简单的2种方法，它可以从Jira项目中获取数据，并向用户分配任务，而这些任务尚待完成。现在，我从Jira API中获取了customfields（time_to_resolution和desired_time_to_resolution），但它看起来不太好，是否可以用一种更加清晰易读的方式来实现？

def assigned_task_list
  assigned_tasks.map do |issue|
    fields = issue.fields

    {
      key: issue.key,
      desired_time_to_resolution: issue.customfield_14777.dig('ongoingCycle', 'remainingTime', 'friendly'),
      time_to_resolution: issue.customfield_10031.dig('ongoingCycle', 'remainingTime', 'friendly'),
      name: fields.dig('assignee', 'name'),
      email: fields.dig('assignee', 'emailAddress'),
      status: fields.dig('status', 'name')
    }
  end
end

下面的assigned_tasks方法：

def assigned_tasks
  project.issues.select do |issue|
    issue.fields.dig('status', 'name') != 'Done' &&
      issue.fields.dig('assignee', 'name')
  end
end

您可以创建多个方法并将其隐藏在其中。

def assigned_task_list
  assigned_tasks.map do |issue|
    {
      key: issue.key,
      desired_time_to_resolution: desired_time_to_resolution(issue),
      time_to_resolution: time_to_resolution(issue),
      name: name(issue),
      email: email(issue),
      status: status(issue)
    }
  end
end

private

def desired_time_to_resolution(issue)
  issue.customfield_14777.dig('ongoingCycle', 'remainingTime', 'friendly')
end

def time_to_resolution(issue)
  issue.customfield_10031.dig('ongoingCycle', 'remainingTime', 'friendly')
end

def name(issue)
  issue.fields.dig('assignee', 'name')
end

def email(issue)
  issue.fields.dig('assignee', 'emailAddress')
end

def status(issue)
  issue.fields.dig('status', 'name')
end
