Question

我想在devise registration view中添加自定义字段标记，但该字段在users表中不存在。我只是希望用户在该字段中选择一些值，并在注册时获得有关params中所选值的信息。谁能建议我怎么做？

Devise_registration_view:

<h2>Sign up</h2>

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

  <div class="field">
    <%= f.label :email %><br />
    <%= f.email_field :email, autofocus: true, autocomplete: "email" %>
  </div>

  <div class="field">
    <%= f.label :password %>
    <% if @minimum_password_length %>
    <em>(<%= @minimum_password_length %> characters minimum)</em>
    <% end %><br />
    <%= f.password_field :password, autocomplete: "off" %>
  </div>

  <div class="field">
    <%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation, autocomplete: "off" %>
  </div>

  <div class="field">
    <%= f.label :type, 'Role' %>
    <%= f.select :type, %w{Admin Teacher Student Guardian}, :prompt => 'Select', required: true, placeholder: 'Roles' %>
  </div>

  <div class="actions">
    <%= f.submit "Sign up" %>
  </div>
<% end %>

<%= render "devise/shared/links" %>

您可以将attr_accessor用于User模型，它将帮助您获取和设置表中不存在的属性值，请参阅此链接。 attr_accessor_details

更新为attr_accessor

创建的属性添加自定义验证的答案

attr_accessor :test_attribute
validate :check_test_attribute
def check_test_attribute
  errors.add(:test_attribute, "is missing") if test_attribute.blank?
end
