设计隐藏字段 [英] Devise hidden fields

问题描述

我创建了一个设计模型

迁移是:

t.string :provider, null: false, default: "email"
t.string :uid, null: false, default: ""

## Database authenticatable
t.string :encrypted_password, null: false, default: ""

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

# etc...

当我执行 rails c 并键入 User 时，我会看到其列的巨大列表

When I do rails c and type User there I get a huge list of its columns

User(id: integer, provider: string, uid: string, encrypted_password: 
string, reset_password_token: string, reset_password_sent_at: datetime, 
remember_created_at: datetime, sign_in_count: integer,
current_sign_in_at: datetime, last_sign_in_at: datetime, 
current_sign_in_ip: string, last_sign_in_ip: string, 
confirmation_token: string, confirmed_at: datetime, 
confirmation_sent_at: datetime, unconfirmed_email: string...

但是当我键入 u = User.find(1)时.它只有一些列 id，provider，uid，created_at，updated_at .

But when I type u = User.find(1). It has only some columns id, provider, uid, created_at, updated_at.

当我执行 u.to_json 时，我得到 {"id":1，"provider":"email"，"uid":"[e-mail]"，名称:"名称，"姓:"姓，"电子邮件:" [e-mail]，" created_at:" 2016-08-07T18:27:24.186Z，" updated_at:" 2016-08-07T18:34:48.647Z} .

它会忽略诸如 confirmed_at ， confirmation_sent_at 等字段...

It ignores fields like confirmed_at, confirmation_sent_at etc...

因此，我想在模型中添加更多隐藏"列.我该怎么办?

So, I want to add some more "hidden" columns in my model. How do I do it?

谢谢！

推荐答案

Devise具有 BLACKLIST_FOR_SERIALIZATION 常量.在源中检查它: https://github.com/plataformatec/devise/blob/master/lib/devise/models/authenticatable.rb#L59

Devise has BLACKLIST_FOR_SERIALIZATION constant for it. Check it in source: https://github.com/plataformatec/devise/blob/master/lib/devise/models/authenticatable.rb#L59

您可以使用以下行在 config/initializers/devise.rb 的Devise配置中隐藏序列化列，例如:

You can hide columns from serialization in your Devise config at config/initializers/devise.rb with line like:

Devise :: Models :: Authenticatable :: BLACKLIST_FOR_SERIALIZATION.concat [:column_1，:column2]
