我有一个名为 bikes 的集合,如下所示:
{
"fname": "foo",
"indian":"hero-corps"
"brands": [
{
"region": "asia",
"type": "terrain"
}
]
}
通过这样的帖子获取json(我们将其命名为 jsonBody ):
{
"indian": "hero-corps",
"someKeyA": "someValueA",
}
我正在使用以下mongo更新查询:
db.collection(bikes).update({"indian":"hero-corps"},{$set:jsonBody}, {upsert:true});
问题在于它在主对象内部进行插入,我只想在嵌套对象品牌中使用 jsonBody 进行插入。我如何实现这一目标?
实际结果:
{
"fname": "foo",
"indian": "hero-corps",
"brands": [
{
"region": "asia",
"type": "terrain"
}
],
"indian": "hero-corps",
"someKeyA": "someValueA",
}
预期结果:
{
"fname": "foo",
"indian": "hero-corps",
"brands": [
{
"region": "asia",
"type": "terrain",
"someKeyA": "someValueA",
}
]
}

我不确定这是否是您要执行的操作,但我确定它将提供您想要的格式。
db.collection(bikes).update({“ indian”:“ hero-corps”},{$ push:{“ brands”:jsonBody}},{upsert:true});
