beego mysql如何时间筛选当日、本周、本月数据？采用高级查询
num, err := o.QueryTable("Fruits").Filter("Shi","2021").Limit(page_size, tebs).All(&posts)
你好,请问beego获取的时间为空怎么办，其他字段都可以获取到，数据库中也有时间字段，就是获取不到
我的写法
数据库连接
麻烦帮我看看，到底是哪里出了问题
Beego框架 get请求编写
目录
根据业务需求，就是需要查询两表的数据，我用了一个笨方法。直接上代码
代码

限制页码查询
current 代表页数
pageSize 代表每页显示几个

m2m
后面同事跟我说有个多对多模型定义，我摸了半天没摸懂，看了go - 在beego orm中插入具有m2m的模型文章仿写了下
开始我一直折腾模型定义的rel_table和rel_through，以及参考文章后面发现没有调用m2m，我也不知道啥问题
func M2mTest()
o := orm.NewOrm()
var data TestData
data.DataTestData = "CoolDude"
id, err := o.Insert(&data)
if err != nil
log.Printf(err.Error())
else
log.Printf("Player ID: %v", id)
var device TestDevice
id, err = o.Insert(&device)
if err != nil
log.Printf(err.Error())
else
log.Printf("Game ID: %v", id)
m2m := o.QueryM2M(&device, "DevGetJsonData")
num, err := m2m.Add(data)
fmt.Println(m2m.Add(data))
if err == nil
log.Printf("Added nums: %v", num)
// m2m.Remove(63)
