Question

我在尝试使用dataTable列出表中的用户时遇到了问题。

到目前为止一切工作正常但是当我输入超过10个用户时，它仍然显示10行，并且不能查看超过10行。我一直试图通过10 25 50 100个条目来使用该节目，但仍然无法正常工作。

以下是我尝试使用的功能的屏幕截图：

Here is the screen shot of the function that i've been trying to use

这是我使用的表格：

$(document).ready(function() {
    $('table.dataTable').dataTable();

} );

这是我的域名：

class Pilot {

    String fName
    String lName

    static constraints = {
    }
}

这是控制器：

class PilotController {

    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)
        [pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
    }

    def create() {
        [pilotInstance: new Pilot(params)]
    }

    def save() {
        def pilotInstance = new Pilot(params)
        if (!pilotInstance.save(flush: true)) {
            render(view: "create", model: [pilotInstance: pilotInstance])
            return
        }

        flash.message = message(code: 'default.created.message', args: [message(code: 'pilot.label', default: 'Pilot'), pilotInstance.id])
        redirect(action: "show", id: pilotInstance.id)
    }

    def show(Long id) {
        def pilotInstance = Pilot.get(id)
        if (!pilotInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "list")
            return
        }

        [pilotInstance: pilotInstance]
    }

    def edit(Long id) {
        def pilotInstance = Pilot.get(id)
        if (!pilotInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "list")
            return
        }

        [pilotInstance: pilotInstance]
    }

    def update(Long id, Long version) {
        def pilotInstance = Pilot.get(id)
        if (!pilotInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "list")
            return
        }

        if (version != null) {
            if (pilotInstance.version > version) {
                pilotInstance.errors.rejectValue("version", "default.optimistic.locking.failure",
                          [message(code: 'pilot.label', default: 'Pilot')] as Object[],
                          "Another user has updated this Pilot while you were editing")
                render(view: "edit", model: [pilotInstance: pilotInstance])
                return
            }
        }

        pilotInstance.properties = params

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

        flash.message = message(code: 'default.updated.message', args: [message(code: 'pilot.label', default: 'Pilot'), pilotInstance.id])
        redirect(action: "show", id: pilotInstance.id)
    }

    def delete(Long id) {
        def pilotInstance = Pilot.get(id)
        if (!pilotInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "list")
            return
        }

        try {
            pilotInstance.delete(flush: true)
            flash.message = message(code: 'default.deleted.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "list")
        }
        catch (DataIntegrityViolationException e) {
            flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'pilot.label', default: 'Pilot'), id])
            redirect(action: "show", id: id)
        }
    }
}

找到解决此问题的方法，

def list(Integer max) {
        params.max = Math.min(max ?: 10, 100)
        [pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
    }

您需要做的就是删除：

Math.min(max ?: 10, 100)在控制器中，

所以你的代码应该是这样的

def list(Integer max) {
        params.max 
        [pilotInstanceList: Pilot.list(params), pilotInstanceTotal: Pilot.count()]
    }

希望如果您有任何人面临同样的问题，这将有助于您。

Answer 2

如果没有给出最大值，PilotController.list（..）会返回10个条目，但是你没有设置最大值，其他任何事情都不会发生。

你评论了分页，所以没有办法获得以下条目。

dataTable表中不能显示10行以上
