type Company struct {
Id string db:"id" form:"id" json:"id"
ComDesc string db:"com_desc" form:"com_desc" json:"com_desc"
ComName string db:"com_name" form:"com_name" json:"com_name"
}
func (b *Company) Store(sess db.Session) db.Store {
return sess.Collection("sys_company_t")
}

this is my model , i use .Save(record) method , the log show insert success , but the database is none.

Transaction ID: 00004
Query: INSERT INTO sys_company_t (com_desc, com_name, id) VALUES (?, ?, ?)
