我的用例很简单，在一个名为dashboard/incomesI display a form to update a record of type的页面中IncomeSetting。

#income-setting-form
  h4 Income Settings
  p Please set your Income Settings using the form below.

  = render 'income_settings/form'

这将生成用于编辑此类对象的表单：

= simple_form_for @income_setting do |f|

  = f.hidden_field :user_id

  = f.error_notification

  .form-group
    = f.label :amount
    = f.input_field :amount, required: true, class: 'form-control'
    = f.error :amount, id: 'amount_error'

  = f.association :income_frequency_type, label: 'Frequency:', collection: IncomeFrequencyType.order('id ASC'), include_blank: false, wrapper_html: { class: 'form-group' }, input_html: { class: 'form-control' }

  .form-group
    = f.label :start_date
    = f.input_field :start_date, required: true, as: :string, class: 'form-control datepicker'
    = f.error :start_date, id: 'start_date_error'

  = f.association :savings_rate_type, label: 'Savings Rate:', collection: SavingsRateType.order('name ASC'), include_blank: false, wrapper_html: { class: 'form-group' }, input_html: { class: 'form-control' }

  .form-group
    = f.label :description
    = f.input_field :description, required: true, class: 'form-control'
    = f.error :description, id: 'amount_error'

  button.btn.btn-primary.btn-block type='submit' Save

为了保持 RESTful 和易于维护，我决定将IncomeSetting对象的所有操作都保存在income_settings_controller.rb文件中。

  def update
    if @income_setting.update(income_setting_params)
      redirect_to dashboard_income_path, notice: 'Your Income Setting was saved successfully updated.'
    else
      redirect_to controller: 'dashboard', action: 'income'
    end
  end

您是否看到验证失败的地方，我重定向到仪表板？如果我在那里放置一个断点，我可以看到模型@income_setting 确实存在验证错误 - 但就像控制器重定向模型错误一样丢失？

关于如何持久化这些错误以便它们在render 'income_settings/form调用时实际显示的任何建议？

您需要dashboard/income在错误条件下呈现而不是重定向。由于您将表单请求发送到单独的控制器，因此您可能必须重复/共享设置逻辑以呈现该页面：

def update
  if @income_setting.update(income_setting_params)
    redirect_to dashboard_income_path, notice: 'Your Income Setting was saved successfully updated.'
  else
    # additional setup may be necessary
    render 'dashboard/income'
  end
end
