1、在IBLL
在InterfaceCommonModelService接口中添加获取公共模型列表的方法
首先排序方法

在CommonModelService写方法实现代码，内容都很简单主要是思路，直接上代码
public IQueryable<CommonModel> FindPageList(out int totalRecord, int pageIndex, int pageSize, string model, string title, int categoryID, string inputer, Nullable<DateTime> fromDate, Nullable<DateTime> toDate, int orderCode)
{
//获取实体列表
IQueryable<CommonModel> _commonModels = CurrentRepository.Entities;
if (model == null || model != "All") _commonModels = _commonModels.Where(cm => cm.Model == model);
if (!string.IsNullOrEmpty(title)) _commonModels = _commonModels.Where(cm => cm.Title.Contains(title));
if (categoryID > 0) _commonModels = _commonModels.Where(cm => cm.CategoryID == categoryID);
if (!string.IsNullOrEmpty(inputer)) _commonModels = _commonModels.Where(cm => cm.Inputer == inputer);
if (fromDate != null) _commonModels = _commonModels.Where(cm => cm.ReleaseDate >= fromDate);
if (toDate != null) _commonModels = _commonModels.Where(cm => cm.ReleaseDate <= toDate);
_commonModels = Order(_commonModels, orderCode);
totalRecord = _commonModels.Count();
return PageList(_commonModels, pageIndex, pageSize).AsQueryable();
}
public IQueryable<CommonModel> Order(IQueryable<CommonModel> entitys, int orderCode)
{
switch(orderCode)
{
//默认排序
default:
entitys = entitys.OrderByDescending(cm => cm.ReleaseDate);
break;
}
return entitys;
}
|
3、web
由于CommonModel跟我们前台显示的数据并不一致，为了照顾datagrid中的数据显示再在Ninesky.Web.Models中再构造一个视图模型CommonModelViewModel

public ActionResult JsonList(string title, string input, Nullable<int> category, Nullable<DateTime> fromDate, Nullable<DateTime> toDate, int pageIndex = 1, int pageSize = 20)
{
if (category == null) category = 0;
int _total;
var _rows = commonModelService.FindPageList(out _total, pageIndex, pageSize, "Article", title, (int)category, input, fromDate, toDate, 0).Select(
cm => new Ninesky.Web.Models.CommonModelViewModel()
{
CategoryID = cm.CategoryID,
CategoryName = cm.Category.Name,
DefaultPicUrl = cm.DefaultPicUrl,
Hits = cm.Hits,
Inputer = cm.Inputer,
Model = cm.Model,
ModelID = cm.ModelID,
ReleaseDate = cm.ReleaseDate,
Status = cm.Status,
Title = cm.Title
});
return Json(new { total = _total, rows = _rows.ToList() });
}

下面是做界面了，在添加 List方法，这里不提供任何数据，数据在JsonList 中获得

上面都是easyui-datagrid的内容。
总体思路是BLL中实现查询公共模型列表，web中添加一个JsonList方法调用BLL中的方法并返回列表的Json类型。然后再添加一个List调用JsonList用来显示。下篇文章做删除和修改操作，希望大家会持续关注。
