我有两个模型：<head>
...
<!-- Google Tag Manager --> <script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src= 'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f); })(window,document,'script','dataLayer','GTM-PRMQXXX');</script> <!-- End Google Tag Manager -->
<!-- Page-hiding snippet (recommended) -->
<style>.async-hide { opacity: 0 !important} </style>
<script>(function(a,s,y,n,c,h,i,d,e){s.className+=' '+y;h.start=1*new Date;
h.end=i=function(){s.className=s.className.replace(RegExp(' ?'+y),'')};
(a[n]=a[n]||[]).hide=h;setTimeout(function(){i();h.end=null},c);h.timeout=c;
})(window,document.documentElement,'async-hide','dataLayer',4000,
{'GTM-KL7XXXX':true});</script>
<!-- Modified Analytics tracking code with Optimize plugin -->
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-99999999-1', 'auto');
ga('require', 'GTM-KL7XXXX');
ga('send', 'pageview');
</script>
...
</head>
和Account。在Profile中，我有Account列。我需要将role列添加到role表中。
我将包含在profiles Profile关联中，并将has_one :account包含在belongs_to :profile模型中。我认为解决方案就在那附近。
Accountclass Profile < ApplicationRecord
has_one :account
end
class Account < ApplicationRecord
devise :registerable, :database_authenticatable, :rememberable,
:trackable, :confirmable, :lockable, :recoverable, :validatable
belongs_to :profile, foreign_key: 'profile_id'
enum role: %i[user admin]
end
我要在 create_table "accounts", 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.string "remember_token"
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.string "confirmation_token"
t.datetime "confirmed_at"
t.datetime "confirmation_sent_at"
t.string "unconfirmed_email"
t.integer "failed_attempts", default: 0, null: false
t.string "unlock_token"
t.datetime "locked_at"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.bigint "profile_id", null: false
t.integer "role", default: 0
t.index ["profile_id"], name: "index_accounts_on_profile_id"
end
create_table "profiles", force: :cascade do |t|
t.string "last_name", null: false
t.string "first_name", null: false
t.string "middle_name"
t.string "email", null: false
t.text "about"
t.date "hire_date", null: false
end
列中添加到profiles表中的哪个对象。
答案 0 :(得分：0)
仅使用从role访问accounts数据的函数
class Profile < ApplicationRecord
def role
return account.role unless account.nil?
end
end
