在mongodb中的嵌套数组中插入数据 [英] Insert data in nested array in mongodb
问题描述
可能重复:
MongoDB更新嵌套数组中的字段
Possible Duplicate:
MongoDB updating fields in nested array
我有类似的数据:
{
"_id" : ObjectId("4f855061dd53351011000b42"),
"act_mgr" : [{ "sales" : {"agent" : ["rohan@walkover.in" ], "last_interacted" : "rohan@walkover.in" } } ],
"email" : "aman@asasas.com", "name" : "Aman",
"sales" : [{"sno" : 1, "message" : "description","status" : "open"},{"sno" : 12,"message" : "assad","status" :"open"}]
}
我想添加新代理并更新act_mgr中的last_interacted:销售类似的东西
I want to add new agent and update last_interacted in act_mgr:sales something like that
"act_mgr" : [{ "sales" : {"agent" : ["rohan@walkover.in","abc@walkover.in" ],
"last_interacted" : "abc@walkover.in" } } ]
另外，如果我像开发人员一样添加新的act_mgr，那就就像
Also if I add new act_mgr like developer then it would be like
"act_mgr" : [{ "sales" : {"agent" : ["rohan@walkover.in","abc@walkover.in" ], "last_interacted" : "abc@walkover.in" } },
{ "developer" : {"agent" : ["newdeveloper@walkover.in" ], "last_interacted" : "newdeveloper@walkover.in" } } ]
我不知道如何添加这些字段
I dont know how to add these fields
推荐答案
您可以使用以下更新语句来更新"act_mgr"数组内的嵌入式"sales"文档:
You can update the embedded "sales" document inside of the "act_mgr" array with the following update statement:
> db.sales.update({"act_mgr.sales.last_interacted":"rohan@walkover.in"}, {$push:{"act_mgr.$.sales.agent":"abc@walkover.in"}, $set:{"act_mgr.$.sales.last_interacted":"abc@walkover.in"}})
> db.sales.find().pretty()
{
"_id" : ObjectId("4f855061dd53351011000b42"),
"act_mgr" : [
{
"sales" : {
"agent" : [
"rohan@walkover.in",
"abc@walkover.in"
],
"last_interacted" : "abc@walkover.in"
}
}
],
"email" : "aman@asasas.com",
"name" : "Aman",
"sales" : [
{
"sno" : 1,
"message" : "description",
"status" : "open"
},
{
"sno" : 12,
"message" : "assad",
"status" : "open"
}
]
}

您可以将包含开发人员"信息的嵌入式文档添加到数组中，如下所示:
You can add the embedded document containing the "developer" information to the array like so:
> db.sales.update({"_id" : ObjectId("4f855061dd53351011000b42")}, {$push:{"act_mgr":{ "developer" : {"agent" : ["newdeveloper@walkover.in" ], "last_interacted" : "newdeveloper@walkover.in" } }}})
> db.sales.find().pretty()
{
"_id" : ObjectId("4f855061dd53351011000b42"),
"act_mgr" : [
{
"sales" : {
"agent" : [
"rohan@walkover.in",
"abc@walkover.in"
],
"last_interacted" : "abc@walkover.in"
}
},
{
"developer" : {
"agent" : [
"newdeveloper@walkover.in"
],
"last_interacted" : "newdeveloper@walkover.in"
}
}
],
"email" : "aman@asasas.com",
"name" : "Aman",
"sales" : [
{
"sno" : 1,
"message" : "description",
"status" : "open"
},
{
"sno" : 12,
"message" : "assad",
"status" : "open"
}
]
}

可以在更新"文档中找到有关$ push和$ set修饰符的文档: http://www.mongodb.org/display/DOCS/Updating
The documentation on the $push and $set modifiers may be found in the "Updating" documentation: http://www.mongodb.org/display/DOCS/Updating
有关使用Mongo db创建和更新嵌入式文档的更多信息，请参见标题为点表示法(到达对象)"的文档. http://www.mongodb.org/display/DOCS/Dot+Notation+% 28Reaching + into + Objects％29
More information on creating and updating embedded documents with Mongo db may be found in the documentation titled "Dot Notation (Reaching into Objects)" http://www.mongodb.org/display/DOCS/Dot+Notation+%28Reaching+into+Objects%29
有关使用"$"位置运算符更新嵌入文档的信息，可在更新"文档的"$位置运算符"部分中找到.
http://www.mongodb.org/display/DOCS/Updating#Updating-The%24positionaloperator
Information on updating embedded documents using the "$" positional operator may be found in the "The $ positional operator" section of the "Updating" documentation.
http://www.mongodb.org/display/DOCS/Updating#Updating-The%24positionaloperator
警告:通常，嵌入文档都匹配相同的结构是更常见的，因此可以更轻松地引用各个嵌入文档.您的销售"数组就是一个很好的例子.每个嵌入的文档包含相同的键"sno"，"message"和"status"
A word of caution: It is generally more common to have embedded documents all match the same structure, so that individual embedded documents may be referenced more easily. Your "sales" array is a good example of this; each embedded document contains the same keys, "sno", "message", and"status"
但是，"act_mgr"数组中的嵌入式文档包含不同的密钥.第一个包含销售"，第二个包含开发人员".相反，请考虑以下结构:
However, the embedded documents inside your "act_mgr" array contain different keys; the first contains "sales", and the second contains "developer". Instead, maybe consider the following structure:
"act_mgr" : [
{
"title" : "sales",
"agent" : [
"rohan@walkover.in",
"abc@walkover.in"
],
"last_interacted" : "abc@walkover.in"
},
{
"title": "developer",
"agent" : [
"newdeveloper@walkover.in"
],
"last_interacted" : "newdeveloper@walkover.in"
}
]
现在，每个嵌入式文档都包含相同的键，即标题"，代理"和"last_interacted".
Now, each embedded documents contain the same keys, "title", "agent", and "last_interacted".
您可以使用以下命令更新子文档.
You could update sub-documents with the following command.
> db.sales.update({"act_mgr.title":"sales"}, {$push:{"act_mgr.$.agent":"abc@walkover.in"}, $set:{"act_mgr.$.last_interacted":"abc@walkover.in"}})
希望这将使您能够进行所需的更新，并可能为您提供有关架构设计的一些思考.祝你好运！
Hopefully this will allow you to make the updates that you need to, and perhaps give you some food for thought regarding schema design. Good luck!
