i have three collection one is User, Store, Map
Map: Collection :
{
"_id" : ObjectId("5fc91244c99e953e48b3f1fc"),
"serviceProviderAdminId" : "5fc91242c99e953e48b3f1fa",
"storeId" : "5f59cbceefca3f304c81e042",
"createdAt" : ISODate("2020-12-03T16:28:52.164Z"),
"role" : "spadmin",
"__v" : 0
}
User Collection:
{
"_id" : ObjectId("5fc91242c99e953e48b3f1fa"),
"mNumber" : 98917,
"area" : "Noida",
"email" : "bhuraspadmin@gmail.com",
"name" : "bhurasuar sp admin",
"role" : "spadmin",
"__v" : 0
}
Store Collection:
{
"_id" : ObjectId("5f59cbceefca3f304c81e042"),
"title" : "bhura suar",
"storeCommunicationEmailId" : ""
}
I want to update storeCommunicationEmailId field of document in collection Store. where Updating criteria is that I have to find user from User collection where the _id of User and serviceProviderAdminId of Map collection is same and get the email value of matching result from user collection and update the email into the document of Store collection where the _id in a document of Store Collection and storeId of the document of Map collection is same.
basically the result of query should be Store collection
{
"_id" : ObjectId("5f59cbceefca3f304c81e042"),
"title" : "bhura suar",
"storeCommunicationEmailId" : "bhuraspadmin@gmail.com"
}
