Question

我正在为我的应用程序使用设计验证。所以我正在尝试使用单选按钮标记，但我收到错误未定义方法`permit'表示“status”：字符串在 NoMethodError in设计:: RegistrationsController #create 。在注册页面我只是添加一个单选按钮标签但是收到了该错误。
[视图/设计/注册/ new.html.erb]

<h2>Sign up</h2>

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

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

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


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

    <div >

      <%= f.label "user" %>
      <%= radio_button_tag 'user','status' %>


      </div>


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

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

[user.rb]

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  has_many :posts
  has_many :comments

  validates :status,presence:true

  def self.find_role(id)
    User.find(id).roles
  end   

end

我的用户表中还有一个状态列

Answer 1

我认为问题是radio_button_tag会覆盖传递给设计控制器的所有参数。在您的观看中尝试<%= radio_button_tag 'user[status]','1' %>，而不是现在的情况。您需要调整status类型。在这里，我只是假设它是一个字符串。

Answer 2

另外，radio_button_tag应该只是f.radio_button。标签不是必需的。

并确保config / initializers / devise.rb具有'config.scoped_views = true'以允许您编辑设计表单。

Rails使用单选按钮标记
