Question

我有一个控制器资源包tachemanagement

import org.springframework.dao.DataIntegrityViolationException

import tachemanagement.secu.Role

class RessourceeeController {

static allowedMethods = [save: "POST", update: "POST", delete: "POST"]

def index() {
    redirect(action: "list", params: params)
}

def list(Integer max) {
    params.max = Math.min(max ?: 10, 100)
    [ressourceeeInstanceList: Ressourceee.list(params), ressourceeeInstanceTotal: Ressourceee.count()]
    [ roleInstanceList: Role.list( params ), roleInstanceTotal: Role.count() ]
}

def create() {
    [ressourceeeInstance: new Ressourceee(params)]
    [roleInstance: new Role(params)]



}


def save() {
    def ressourceeeInstance = new Ressourceee(params)
    def roleInstance = new Role(params)

    if (!ressourceeeInstance.save(flush: true)) {
        render(view: "create", model: [ressourceeeInstance: ressourceeeInstance])
        return
    }

    if (!roleInstance.save(flush: true)) {
        render(view: "create", model: [roleInstance: roleInstance])
        return
    }

    flash.message = message(code: 'default.created.message', args: [message(code: 'ressourceee.label', default: 'Ressourceee'), ressourceeeInstance.id])

    catch (DataIntegrityViolationException e) {
        flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'role.label', default: 'Role'), id])
        redirect(action: "show", id: id)
    }
}

} 我已经为我的控制器添加了一个获取角色ID的代码但它产生了一个问题 URI：/ tachemanagement / ressourceee / listClass：org.codehaus.groovy.grails.web.taglib.exceptions.GrailsTagExceptionMessage：Tag [paginate]缺少必需属性[total]

Answer 1

我想你忘了返回“total”变量。例如，在您的某个控制器中，您应该返回：

render(view: "create", model: [roleInstance: roleInstance, max: your_max_variable])

您的信息不清楚哪种操作会产生此类错误以及您如何输入g：pagination taglib

标签[paginate]缺少grails中必需的属性[total]
