从Register.gsp
页面当我提交表单时,它呈现良好并进入列表页面。但问题是它不保存任何数据。如果我通过dbconsole
添加数据,则list.gsp
显示数据。可能是愚蠢的问题,但我在Grails中很初学。提前致谢。无法手动将数据保存到Grails中的数据库中,但使用dbconsole时效果不错
域类:
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]
}
}
