这是我在这里的第一篇帖子:)我有一个CRUD模块的问题。我想在列表中添加更多过滤器,但我无法成功理解工厂模型。我有以下代码:

@With(Secure.class)
public class Contacts extends CRUD {


public static void list(int page,String search,int origine,String searchFields, String orderBy, String order) {
    ObjectType type = ObjectType.get(getControllerClass());
    notFoundIfNull(type);
    if (page < 1) {
        page = 1;
    }

    //System.out.println(type);

    List<Model> contacts = Model.Manager.factoryFor(Contact.class).fetch((page - 1) * getPageSize(), getPageSize(), orderBy, order, searchFields == null ? new ArrayList<String>() : Arrays.asList(searchFields.split("[ ]")), search, (String) request.args.get("where"));
    System.out.println(contacts);

    List<Model> objects = type.findPage(page, search, searchFields, orderBy, order, (String) request.args.get("where"));
    Long count = type.count(search, searchFields, (String) request.args.get("where"));
    Long totalCount = type.count(null, null, (String) request.args.get("where"));


     // Liste des origines
    List<Origine> origines = Origine.find("order by nom asc").fetch();
    List<Employe> employes = Employe.find("order by nom asc").fetch();

    try {
        render(type, objects, count, totalCount, page, orderBy, order, origines,employes);
    } catch (TemplateNotFoundException e) {
        render("CRUD/list.html", type, objects, count, totalCount, page, orderBy, order, origines, employes);
    }
}
@With(Secure.class)
公共类联系人扩展了CRUD{
公共静态无效列表(整型页面、字符串搜索、整型源代码、字符串搜索字段、字符串排序依据、字符串顺序){
ObjectType=ObjectType.get(getControllerClass());
notFoundIfNull(类型);
如果(第<1页){
page=1;
}
//系统输出打印项次(类型);
List contacts=Model.Manager.factoryFor(Contact.class).fetch((第1页)*getPageSize(),getPageSize(),orderBy,order,searchFields==null?新建ArrayList():Arrays.asList(searchFields.split([]),search,(String)request.args.get(“where”);
系统输出打印项次(联系人);
List objects=type.findPage(页面、搜索、搜索字段、orderBy、order、(String)request.args.get(“where”);
Long count=type.count(search,searchFields,(String)request.args.get(“where”);
Long totalCount=type.count(null,null,(String)request.args.get(“where”);
//原汁原味
List origines=Origine.find(“按nom asc排序”).fetch();
List employes=Employe.find(“按nom asc排序”).fetch();
试一试{
呈现(类型、对象、计数、总数、页面、医嘱人、医嘱、来源、雇员);
}捕获(TemplateNotFounde异常){
呈现(“CRUD/list.html”、类型、对象、计数、总数、页面、orderBy、order、origines、employes);
}
}
}


我想搜索“源代码”和“雇员”字段,我该怎么做?谢谢你的帮助。:)

我的代码有了进步!!!你的建议很有帮助!现在我创建了一个新的类Recherche,它扩展了CRUD。我想用dynamic字段更改字段“Contact”,因为我想扩展Contact和Compte以及其他类的Recherche!我测试了ObjectType宽度没有成功
