```ruby

super {|user|
|

user.update(id100: user.id*100)

end

rails serverから新規登録を行うと、id100にuser.id*100の値が書き込まれる。
|
|
106
|
+
rails consoleで確認すると
|
|
107
|
+
```
|
|
108
|
+
user = User.find(102)
|
|
109
|

user.id100

|
110
|
+
=> 10200
|
|
111
|

```
|
|
112
|
+
rails consoleでcreateを実行すると、id100はnilとなる。
|
|
113
|
+
```
|
|
114
|
+
user = User.create(email:"test4@example.com", password:"test0101")
