我有一个表格，其中我正在为特定的固定装置和场地名称创建日期，我无法创建日期。我曾尝试在fixture类中将date设置为nullable:true，以测试场地创建是否有效，结果显示的是场地，但日期不可用

这是我的域名类

package cricketfixturesgrailsapp


class Fixture {

   Date date 
   String venue

   // hasMany  = [scores:Scores]

     static hasMany = [team:Team]

    static constraints = {
      date nullable: true
    }
}

这是我的FixtureController类

package cricketfixturesgrailsapp

class FixtureController {

 //def index() { }
    def fixtureService
    //def scaffold=true

    def add() {
        if (request.method == 'GET') {
            [fixtureBean: new Fixture()]
        }
        else {
            def fixture = fixtureService.createFixture(params.fixture?.date, params.fixture?.venue)
            if (!fixture.hasErrors()) {
                redirect action: 'show', id: fixture.id
                return
            }

            [fixtureBean: fixture]
        }
    }

  def show() {
        def fixture = Fixture.get(params.id)
        if (fixture) {
            [fixtureBean: fixture]
        }

    }
            def find() {
        if (request.method == 'POST') {
            def fixtures = Fixture.findAllByDate(params.date)
            if (fixtures) {
                if (fixtures.size() > 1) {
                    render view: 'selection', model: [fixtures: fixtures]
                }
                else {
                    redirect action: 'show', id: fixtures[0].id
                }
            }
            else {
                [message: 'fixtures.not.found']
            }
        }
    }
}

您的名称不匹配

如果您有：

<g:datePicker name="fixtureBean.date"/>

而不是

fixtureService.createFixture(params.fixture?.date

fixtureService.createFixture(params.fixtureBean?.date

fixtureService.createFixture(params.fixture?.date
