在rails中,如何在验证消息“更正以下错误”之前更改文本?

例如1

  validates :name,
            presence: true,
            length: { maximum: 70 },
            format: { message: 'Please Correct the following errors' }

例如2

   validate :custom_validation

   def custom_validation
     #validation stuffs
     errors.add(:base, 'Please Correct the following errors')
   end

这个问题是 不合理 因为rails本身就是这样工作的。

lib/rails/generators/erb/scaffold/templates/_form.html.erb.tt:
  1  <%%= form_with(model: <%= model_resource_name %>, local: true) do |form| %>
  2    <%% if <%= singular_table_name %>.errors.any? %>
  3      <div id="error_explanation">
  4        <h2><%%= pluralize(<%= singular_table_name %>.errors.count, "error") %>
            prohibited this <%= singular_table_name %> from being saved:</h2>
