我只是按照教程 ”https://github.com/EppO/rolify/wiki/Tutorial“ 它非常好，工作正常。但是我的问题是我们不能通过表单添加角色而不使用Rails控制台吗？

<%= f.fields_for :users do |user_form| %>
    <div class="field"><%= user_form.label :email %><br />
    <%= user_form.email_field :email %></div>
    <div class="field"><%= user_form.label :password %><br />
    <%= user_form.password_field :password %></div>
    <div class="field"><%= user_form.label :password_confirmation %><br />
    <%= user_form.password_field :password_confirmation %></div>
    <div class="field">
      <%= f.label :roles %>
      <div class="controls">
        <% Role.all.each do |role| %>
          <%= check_box_tag "user[role_ids][]", role.id, @user.role_ids.include?(role.id) %>
          <%= role.name %><br />
        <% end %>
      </div>
    </div>
<% end %>

字符串
角色列连接到角色表（Rolify Roles）

这是我的role.rb

class Role < ActiveRecord::Base

  has_and_belongs_to_many :users, :join_table => :users_roles

  belongs_to :resource, :polymorphic => true

型

• User.rb*

class User < ActiveRecord::Base

  belongs_to :account, :inverse_of => :users

  validates :account, :presence => true

  rolify

   attr_accessible :role_ids
   
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable

  devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model

  attr_accessible :email, :password, :password_confirmation, :remember_me, :role_ids

  # attr_accessible :title, :body

  has_many :auditinits
end

型
