這是一個設計的東西？ （註冊後爲用戶設置角色）

Question

我想要2種用戶，老師和學生。現在的問題是，即使我在用戶控制器中爲教師和學生設置了角色，但我的表單顯示選項顯示了VIP和Admin。這是一個設計的東西？我是否需要向我的遷移中添加列？

以下是註冊表格的一部分。省略意味着提前跳過。

<div class="authform"> 
    <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :role => 'form'}) do |f| %> 
    ... 
    <div class="form-group"> 
     <%= f.label :password_confirmation %> 
     <%= f.password_field :password_confirmation, class: 'form-control' %> 
    </div> 
    <div> 
     <%= f.select(:role, User.roles.keys.map {|role| [role.titleize,role]}) %> 
    </div> 

    <%= f.submit 'Sign Up', :class => 'button right' %> 

    <% end %> 
</div> 

這裏是我的用戶控制器

class UsersController < ApplicationController 
    # before_action :authenticate_user! 
    before_action :logged_in_user, only: [:edit, :update] 
    before_action :correct_user, only: [:edit, :update] 
    after_action :verify_authorized 
    # before_filter :check_role 
    enum role: [:student, :teacher] 

    def show 
    @user = User.find(params[:id]) 
    authorize @user 
    @posts = @user.posts 
    end 

    def new 
    @user = User.new 
    authorize @user 
    end 

    def update 
    @user = User.find(params[:id]) 
    authorize @user 
    if @user.update_attributes(secure_params) 
     redirect_to users_path, :notice => "User updated." 
    else 
     redirect_to users_path, :alert => "Unable to update user." 
    end 
    end 

    def destroy 
    user = User.find(params[:id]) 
    # authorize @user 
    user.destroy 
    redirect_to users_path, :notice => "User deleted." 
    end 

    def create_user_type 
    end 

    private 

    def secure_params 
    params.require(:user).permit(:role) 
    end 

    def logged_in_user 
     unless logged_in? 
     flash[:danger] = "Please log in." 
     redirect_to login_url 
     end 
    end 

    def correct_user 
     @user = User.find(params[:id]) 
     redirect_to(root_url) unless @user == current_user 
    end 
end 

所有的老師和學生都有自己的遷移，控制器和輔助文件。這裏是用戶遷移。

class DeviseCreateUsers < ActiveRecord::Migration 
    def change 
    create_table :users do |t| 
     ## Database authenticatable 
     t.string :email,    null: false, default: "" 
     t.string :encrypted_password, null: false, default: "" 

     ## Recoverable 
     t.string :reset_password_token 
     t.datetime :reset_password_sent_at 

     ## Rememberable 
     t.datetime :remember_created_at 

     ## Trackable 
     t.integer :sign_in_count, default: 0, null: false 
     t.datetime :current_sign_in_at 
     t.datetime :last_sign_in_at 
     t.string :current_sign_in_ip 
     t.string :last_sign_in_ip 

     ## Confirmable 
     # t.string :confirmation_token 
     # t.datetime :confirmed_at 
     # t.datetime :confirmation_sent_at 
     # t.string :unconfirmed_email # Only if using reconfirmable 

     ## Lockable 
     # t.integer :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts 
     # t.string :unlock_token # Only if unlock strategy is :email or :both 
     # t.datetime :locked_at 


     t.timestamps null: false 
    end 

    add_index :users, :email,    unique: true 
    add_index :users, :reset_password_token, unique: true 
    # add_index :users, :confirmation_token, unique: true 
    # add_index :users, :unlock_token,   unique: true 
    end 
end 

class AddRoleToUsers < ActiveRecord::Migration 
    def change 
    add_column :users, :role, :integer 
    end 
end 

對不起，這是一個很長的帖子，我只是有點困惑，爲什麼它沒有學生和教師作爲選項，而是顯示 the following

太謝謝你了！

您正在控制器中定義角色枚舉。這應該在用戶模型中。
