Updating complete embedded document in MongoDB - mongodb

Question

I am new to mongoDB, and I am stuck at a simple update operation:
Here is the document that I had stored:
{
"_id" : "xyz",
"basicinfo_showcase_components" : {
"display_name" : "ritesh",
"display_email" : "xyz#gmail.comxsa",
"international_phone_number" : "+91 .....",
},
"address_components" : {
"country" : "India",
"postal_code" : "500004",
"state" : "Telangana",
"city" : "Hyderabad",
"subLocality1" : "aaaa",
"subLocality2" : "",
"subLocality3" : "",
"route" : "",
"geometry" : {
"lat" : 17.43143576387407,
"lng" : 78.464432457672046
},
"formatted_address" : "addrr"
}
}
Now I want to updat the address_components in above document:
I tried:
db.portfolio.update({ "_id" : "xyz", "$isolated" : "true" },
{
"address_components" : {
"country" : "Nepal",
"postal_code" : "878799",
"state" : "Telangana",
"city" : "Kathmandu",
"subLocality1" : "xyz",
"subLocality2" : "",
"subLocality3" : "",
"route" : "",
"geometry" : {
"lat" : 17.43143576387407,
"lng" : 78.464432457672046
},
"formatted_address" : "kath..."
}
});
But after updating, the "basicinfo_showcase_components" is eliminated.
ie. the updated doc is:
{
"_id" : "ohris",
"address_components" : {
.......
}
}
Can you please point out the mistake?

Answer 1

In your update query you passed whole document as your update document, if you want to update just one (or more) fields of document you should use $set operator:
db.test.update({ "_id" : "xyz", "$isolated" : "true" },
{
$set : {
"address_components" : {
"country" : "Nepal",
"postal_code" : "878799",
"state" : "Telangana",
"city" : "Kathmandu",
"subLocality1" : "xyz",
"subLocality2" : "",
"subLocality3" : "",
"route" : "",
"geometry" : {
"lat" : 17.43143576387407,
"lng" : 78.464432457672046
},
"formatted_address" : "kath..."
}
}});
