thinkphp6使用MongoDB多个数据，聚合查询的坑

我使用的是thinkphp6,mongodb4.0实际业务查询

复制代码

  $list = Db::connect('tstd_mongo')
            ->table("$table_time.Item")
            ->where($where)
            ->order("Cause","asc")
            ->field('_id,DBID,Data,GSID,MainKind,ManID,DISTINCT(Serial) Serial,SubKind,Time')

            ->paginate($limit);

->table("$table_time.Item")

我是根据数据，要去不同的数据库查询，需要修改源码

topthink\think-orm\src\db\connector\Mogo.php function command()下，

复制代码

$dbName = $dbName ?: $this->dbName;

修改成

复制代码

if (!empty($this->builder->dbName)){
    $dbName = $dbName ?: $this->builder->dbName;
    $this->dbName=$dbName;
}else{
    $dbName = $dbName ?: $this->dbName;
}

如果使用paginate count 就要修改

topthink\think-orm\src\db\builder\Mongo.php

复制代码

if (strstr($options['table'], '.')!== false) {
    $parts = explode('.',$options['table']);
    $count_db = !empty($parts[0])?$parts[0]:'';
    $count_table = !empty($parts[1])?$parts[1]:'';
    
    
    
    if (!empty($count_table)){
        $options['table']=$count_table;
    }
    if (!empty($count_db)){
        $this->dbName = $count_db;
    }
}

如果用其他，aggregate，select 方法也要加这段代码
