Rails simple_form text_area 不显示错误

Question

我用 simple_form 创建了一个 Rails 表单，如下所示：

= simple_form_for @new_biz, url: new_business_post_path, html: {:class => "customForm1", :method => "post"} do |f|

    = f.input :business_name, label: false, :input_html => {:value => @wat.business_name, :readonly => true}
    = f.input :wat_id, :as => :hidden, :input_html => {:value => @wat.id}
    = f.input :first_name
    = f.input :last_name
    = f.input :email
    = f.input :phone, :label => "Phone number"
    = f.label "Personal Message"
    = f.text_area :message, label: false
    = f.submit "Submit"

和验证：

validates :first_name, presence: {:message => "Please enter the first name."}
validates :last_name, presence: {:message => "Please enter the last name."}
validates :phone, presence: {:message => "Please enter the phone number"}
validates :message, presence: {:message => "Please enter a personal message"}

除 text_area 字段外，所有验证均按预期显示。我似乎找不到其他遇到此问题的人。非常感谢所有建议，谢谢。

您的文本字段输入不应该写成：

= f.input :message, as: :text, label: false

?
