Question

我需要在rails视图中的form_for中为两个输入设置相同的值

         .form-box
          = form_for(resource, as: resource_name, url: registration_path(:user), html: { class: "guest-form", autocomplete: "off" }) do |f|

            = f.text_field :username, placeholder: "Username", class: "input"
            = f.password_field :password, class: "input", style: 'visibility: hidden'
            = f.submit "Enter", class: "signup"

我需要设置：密码相同的值：username。是否可以在不使用jquery或overriding devise的情况下完成它？例如，使用value：attribute？

Answer 1

在您的用户模型中，您可以：

class User
  ...
  before_validation :init_password, on: :create

  private

    def init_password
      self.password = username
    end
end

删除表单的字段。

这必须做到这一点。

Answer 2

您只需传递value属性：

即可设置输入值

     .form-box
      = form_for(resource, as: resource_name, url: registration_path(:user), html: { class: "guest-form", autocomplete: "off" }) do |f|

        = f.text_field :username, placeholder: "Username", class: "input"
        = f.password_field :password, class: "input", style: 'visibility: hidden', value: f.object.username
        = f.submit "Enter", class: "signup"
