從Register.gsp
頁面當我提交表單時,它呈現良好並進入列表頁面。但問題是它不保存任何數據。如果我通過dbconsole
添加數據,則list.gsp
顯示數據。可能是愚蠢的問題,但我在Grails中很初學。提前致謝。無法手動將數據保存到Grails中的數據庫中,但使用dbconsole時效果不錯
域類:
package userreg
class Customer {
String name
Date birthday
String gender
String email
static constraints = {
name blank: false
email blank: false,unique:true
}
}
控制器:
package userreg
class CustomerController {
static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]
def index ={
render(view:'register')
}
def register()
{
}
def save ={
def customer=new Customer(params)
customer.save flush:true
redirect action:"list"
}
def list()
{
def customers=Customer.list()
[customers:customers]
}
}
