ruby-on-rails - 无法刷新错误数组

Question

我在刷新错误数组时遇到问题。目前，我正在调用notice: errors，但这返回的数组看起来像这样

[“请输入分数范围一。”，“请输入分数范围二。”，“请为分数之一输入1至100之间的范围。”，“请为分数二输入1至100之间的范围。”]

如果我调用flash: errors，则会收到此错误
undefined method 'keys' for #<Array:0x0000010f196198>
有什么更好的方法呢？我的代码如下

if beg_score.present? && end_score.present? && beg_score.to_i.between?(1, 100) && end_score.to_i.between?(1, 100)
  CallLogByScoreWorker.perform_async(beg_score, end_score, query)
  redirect_to call_logs_path, notice: 'Calls were successfully made.'
else
  errors = []
  unless beg_score.present?
    errors << 'Please enter score range one.'
  end
  unless end_score.present?
    errors << 'Please enter score range two.'
  end
  unless beg_score.to_i.between?(1, 100)
    errors << 'Please enter range between 1 and 100 for score one.'
  end
  unless end_score.to_i.between?(1, 100)
    errors << 'Please enter range between 1 and 100 for score two.'
  end
redirect_to call_logs_path, flash: errors

Answer 1

代替:

redirect_to call_logs_path, flash: errors

做:

redirect_to call_logs_path, notice: errors.join(' ')

这样，它将返回类似以下的字符串:

'Please enter score range one. Please enter score range two. Please enter range between 1 and 100 for score one. Please enter range between 1 and 100 for score two.'
