Rails 5模型对象未显示所有Devise属性 [英] Rails 5 model objects not showing all Devise attributes

问题描述

我正在使用devise的Rails 5 API。我有一个 User 模型。架构看起来像这样。

I am using Rails 5 API with devise. I have a User model. Schema looks like this.

create_table "users", force: :cascade do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0,  null: false
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.inet     "current_sign_in_ip"
    t.inet     "last_sign_in_ip"
    t.datetime "created_at",                          null: false
    t.datetime "updated_at",                          null: false
    t.index ["email"], name: "index_users_on_email", unique: true, using: :btree
    t.index ["reset_password_token"], name: "index_users_on_reset_password_token",    unique: true, using: :btree
  end

但是我遇到的问题是Rails只显示：id，：email，：created_at，：updated_at attri作为模型的一部分。例如，在Rails控制台中

But the issue I am having is Rails only showing :id , :email , :created_at , :updated_at attributes as part of model. For example, in rails console

 User.new
 => #<User id: nil, email: "", created_at: nil, updated_at: nil> 

 User.first
  User Load (0.5ms)  SELECT  "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT $1  [["LIMIT", 1]]
 => #<User id: 2, email: "[e-mail]", created_at: "2016-09-22 03:58:04", updated_at: "2016-09-22 04:54:41"> 

但是这些属性存在于数据库中。前面已经提到了这个问题。 带导轨5的设计。

But these attributes exist in database.This problem is mentioned earlier . Devise with rails 5 . But no answers there .Please help.

推荐答案

Devise限制诸如 encrypted_pa​​ssword ，这样关键信息就不会在API调用中公开。因此，要覆盖此方法，您需要覆盖 serializable_hash 方法。

Devise restricts attributes like encrypted_password so that the critical information doesn't get exposed in API calls. So to override this, you need to override serializable_hash method.

def serializable_hash(options = nil) 
  super(options).merge(encrypted_password: encrypted_password) 
end

这不是特定于Rails 5的功能，而是旨在保护您的属性的设计功能。

This is not a Rails 5 specific feature but a Devise feature to protect your attributes.
