异常信：:Object does not match target type.检查是否使用了Include，改为Includes
|
|||
|
|
|
|||
|
|
1、主从表分合计不能groupby与tostring("f2")
|
|||
|
|
SummaryExpress = (ISugarQueryable<Demo_Order> queryable) =>
|
|||
|
|
{
|
|||
|
|
//求和这里不需要group
|
|||
|
|
return queryable.Select(x => new
|
|||
|
|
{
|
|||
|
|
//注意大小写和数据库字段大小写一样
|
|||
|
|
TotalPrice =SqlFunc.AggregateSum(x.TotalPrice),
|
|||
|
|
TotalQty = SqlFunc.AggregateSum(x.TotalQty)
|
|||
|
|
})
|
|||
|
|
.FirstOrDefault();
|
|||
|
|
};
|
|||
|
|
|
|||
|
|
2、主从表需要明细表list对上添加Navigate配置
|
|||
|
|
[Navigate(NavigateType.OneToMany, nameof(Order_Id), nameof(Order_Id))]
|
|||
|
|
public List<Demo_OrderList> Demo_OrderList { get; set; }
|
|||
|
|
|
|||
|
|
3、表需要主键属性
|
|||
|
|
[SugarColumn(IsPrimaryKey = true)]
|
|||
|
|
|
|||
|
|
4、GetDetailPage方法需要重新生成查询query
|
|||
|
|
//查询界面统计求等字段
|
|||
|
|
//这里sqlsugar会把IQueryablePage里面的排序字段也添加进去了就会导致异常2023.10.17
|
|||
|
|
queryeable = repository.DbContext.Set<Detail>().Where(whereExpression);
|
|||
|
|
gridData.summary = GetDetailSummary<Detail>(queryeable);
|
|||
|
|
|
|||
|
|
5、GetPageData方法需要重新生成查询query
|
|||
|
|
//查询界面统计求等字段
|
|||
|
|
//这里sqlsugar会把IQueryablePage里面的排序字段也添加进去了就会导致异常2023.10.17
|
|||
|
|
if (SummaryExpress != null)
|
|||
|
|
{
|
|||
|
|
options = ValidatePageOptions(options, out ISugarQueryable<T> queryableSummary);
|
|||
|
|
// queryableSummary = QueryRelativeExpression.Invoke(queryableSummary);
|
|||
|
|
pageGridData.summary = SummaryExpress.Invoke(queryableSummary);
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
6、DictionaryManager字典查询，需要将Include改为Includes
|
|||
|
|
|
|||
|
|
_dictionaries = DBServerProvider.DbContext
|
|||
|
|
.Set<Sys_Dictionary>()
|
|||
|
|
.Includes(c => c.Sys_DictionaryList)
|
|||
|
|
.Where(x => x.Enable == 1)
|
|||
|
|
.ToList();
|
|||
|
|
|
|||
|
|
7、角色控制器、Sys_WorkFlowService、 //WorkFlowManager中 dbContext.Add(workFlowTable); Sys_TableInfoService、Sys_WorkFlowController中Include改为Includes
|
|||
|
|
|
|||
|
|
8、sys_table加上 [SugarColumn(IsPrimaryKey = true,IsIdentity =true)]
|
|||
|
|
InitTable(int 里面 改为 repository.SqlSugarClient.InsertNav<Sys_TableInfo>(tableInfo).Include(x => x.TableColumns).ExecuteCommand();
|
|||
|
|
/// repository.Add(tableInfo, true);
|
|||
|
|
|
|||
|
|
9、sys_userole、Sys_RoleAuth、角色、部门表也要加上 [SugarColumn(IsPrimaryKey = true,IsIdentity =true)]
|
