【暇つぶし】grovvyでblog作ってみたｗ
||
最近流行のgrovvyでお試しにBlogを作ってみた編～＾＾var vglnk = {api_url: '//api.viglink.com/api', key: '0dff9ade2d1125af6c910069b6d6e155'};
意外と簡単！ groovyってすごいな（ってか基本Javaだしｗ）
domain~~
Entry.groovy
package jp.co.test
class Entry {
Date dateCreated
String title
String text
byte[] imageData
static hasMany=[comments:Comment]
static mapping={
comments(sort:"id",order:"asc")
imageData(type:'materialized_blob')
}
static constraints = {
title(blank:false)
text(blank:false,maxSize:1024)
dateCreated()
imageData(nullable:true)
}
}
Comment.groovy
package jp.co.test
class Comment {
String text
static belongsTo=[entry:Entry]
static constraints = {}
}
controller~~~

Viewは長いんで割愛～～
次はPJでも使えそうなTodoリスト作ってみよう～
