### 快速开始
|
|
|
|
初始化mongo数据库连接
|
|
|
|
```go
|
|
client, err := mongodb.ConnInit("mongodb://admin:admin@10.0.0.135:27017/admin")
|
|
if err != nil {
|
|
logrus.Fatalf("get err: %+v", err)
|
|
}
|
|
mdbc.InitDB(client.Database("mdbc"))
|
|
```
|
|
|
|
声明 model
|
|
|
|
```go
|
|
var m = mdbc.NewModel(&ModelSchedTask{})
|
|
```
|
|
|
|
然后就可以使用 m 进行链式操作
|
|
|
|
### 注册全局对象
|
|
|
|
可以将model注册成一个全局变量
|
|
```go
|
|
type WsConnectRecordScope struct {
|
|
*mdbc.Scope
|
|
}
|
|
|
|
var WsConnectRecord *WsConnectRecordScope
|
|
|
|
func NewWsConnectRecord() {
|
|
WsConnectRecord = new(WsConnectRecordScope)
|
|
WsConnectRecord.Scope = mdbc.NewModel(&model.ModelWsConnectRecord{})
|
|
}
|
|
```
|
|
|
|
使用：
|
|
|
|
```go
|
|
func beforeRemoveWs(ctx context.Context, recordID, key string) {
|
|
if WsConnectRecord == nil {
|
|
NewWsConnectRecord()
|
|
}
|
|
tm := time.Now().UnixNano() / 1e6
|
|
if message_common.GetEtcdWatcher().RemoveWatch(key) {
|
|
// 已经移除 变更最近的一条消息
|
|
err := WsConnectRecord.SetContext(ctx).FindOne().SetFilter(bson.M{
|
|
model.ModelWsConnectRecordField_Id.DbFieldName: recordID,
|
|
}).Update(bson.M{
|
|
"$set": bson.M{
|
|
model.ModelWsConnectRecordField_LogoutAt.DbFieldName: tm,
|
|
},
|
|
})
|
|
if err != nil {
|
|
log.Errorf("update ws conn record err: %+v", err)
|
|
common.Logger.Error(ctx, "WsConn", log2.String("error", err.Error()))
|
|
}
|
|
}
|
|
}
|
|
```
