ruby-on-rails – 尝试在Rails 4中通过ActiveAdmin创建新用户时,

我的设置 – Rails 4,ActiveAdmin,Devise生成的用户模型.用户使用用户名进行身份验证,但没有email属性.我提到了最后一个,因为Devise严重依赖于email属性,所以这可能与问题有关.我的确切设置和代码描述为 in this blog post.

在ActiveAdmin后端,我转到用户 – >新用户 – >填写用户名,密码,密码确认 – >创建用户.新用户表单被删除而不是创建新用户,而在密码字段下我得到的错误不能为空.当我转到Rails控制台并手动创建一个新用户User.create(用户名：’Joe’,密码：’password’,password_confirmation：’password’)一切正常,用户可以登录localhost：3000 /用户/ sign_in.

我看到了这个SO question.如果我添加到我的用户模型：

def password_required?
  new_record? ? false : super
end

我可以创建一个新用户,但所有字段(包括用户名,加密密码)都是空白的.

更新正如Leger建议的那样,我发布了我的代码.当我使用Devise和Activeadmin的内置控制器时,我认为在Activeadmin和我的数据库模式中发布我的用户资源的代码是有意义的：

Activeadmin中的用户资源：

ActiveAdmin.register User do
  # This determines which attributes of the User model will be displayed in the index page. I have left only username,but feel free to uncomment the rest of the lines or add any other of the User attributes.
  index do
    column :username
    # column :current_sign_in_at
    # column :last_sign_in_at
    # column :sign_in_count
    default_actions
  end

  # Default is :email,but we need to replace this with :username
  filter :username

  # This is the form for creating a new user using the Admin backend. If you have added additional attributes to the User model,you need to include them here.
  form do |f|
    f.inputs "User Details" do
      f.input :username
      f.input :password
      f.input :password_confirmation
    end
    f.actions
  end

  # This is related to Rails 4 and the changes it introduced in handling strong parameters. Here we replace :email with :username.
  controller do
    def permitted_params
      params.permit admin_user: [:username,:password,:password_confirmation]
    end
  end
end

schema.rb：

ctiveRecord::Schema.define(version: 20131031102826) do

  create_table "active_admin_comments",force: true do |t|
    t.string   "namespace"
    t.text     "body"

    t.datetime "updated_at"
  end

  add_index "admin_users",["email"],name: "index_admin_users_on_email",unique: true
  add_index "admin_users",["reset_password_token"],name: "index_admin_users_on_reset_password_token",unique: true

  create_table "users",force: true do |t|
    t.string   "username",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"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

  add_index "users",name: "index_users_on_reset_password_token",unique: true
  add_index "users",["username"],name: "index_users_on_username",unique: true

end
