Question

我有以下引导类

import shoppingsolutionproject.Category;
import shoppingsolutionproject.Item

class BootStrap {

    def dataSource

    def init = { servletContext ->
        new Category(description: 'Car').save()
        new Category(description: 'Truck').save()
        new Item(productNumber:1, name:"First Product", description: "This is the first product I'm adding for testing",
                 shippingCost: 4.99, url: '/first', retailPrice: 19.99, salePrice: 16.99, category: 'Car').save()
        new Item(productNumber:2, name:"Second Product", description: "This is the second product I'm adding for testing",
                shippingCost: 4.99, url: '/second', retailPrice: 19.99, category: 'Truck').save()
        new Item(productNumber:3, name:"First/Second Product", description: "This is the first/second(so third) product I'm adding for testing",
                shippingCost: 4.99, url: '/second', retailPrice: 17.99, category: 'Truck').save()
    }
    def destroy = {
    }
}

当我启动grails时，我没有预先填充的类别或项目...任何想法为什么？

Answer 1

您很可能有验证错误。

验证这一点的最快方法是向failOnError: true添加.save()，如下所示：.save(failOnError: true)。

这应该会显示许多因验证错误而失败的事情。

为什么grails没有通过bootstrap填充数据
