Doc:
{
_id: 5150a1199fac0e6910000002,
name: 'some name,
items: [{
id: 23,
name: 'item name 23'
},{
id: 24,
name: 'item name 24'
}]
}
Is there a way to pull a specific object from an array? I.E. how do I pull the entire item object with id 23 from the items array.
I have tried:
db.mycollection.update({'_id': ObjectId("5150a1199fac0e6910000002")}, {$pull: {id: 23}});
However I am pretty sure that I am not using 'pull' correctly. From what I understand pull will pull a field from an array but not an object.
Any ideas how to pull the entire object out of the array.
As a bonus I am trying to do this in mongoose/nodejs, as well not sure if this type of thing is in the mongoose API but I could not find it.
try..
db.mycollection.update(
{'_id': ObjectId("5150a1199fac0e6910000002")},
{ $pull: { "items" : { id: 23 } } },
false,
true
);
I have a document like
I have to delete address from address array
After searching lots on internet I found the solution
Customer.findOneAndUpdate(query, {$pull: {address: addressId}}, function(err, data){
if(err) {
return res.status(500).json({'error' : 'error in deleting address'});
}
res.json(data);
});
my database:->
{
"_id" : ObjectId("5806056dce046557874d3ab18"),
"data" : [
{
"id" : 1
},
{
"id" : 2
},
{
"id" : 3
}
]
}
MY QUERY:->
db.getCollection('play_table').update({},{$pull:{"data":{"id":3}}},{multi:true}
OutPut:->
{
"_id" : ObjectId("5806056dce046557874d3ab18"),
"data" : [
{
"id" : 1
},
{
"id" : 2
}
]
}
You can try it also:
db.getCollection('docs').update({ },{'$pull':{ 'items':{'id': 3 }}},{multi:true})
Use $pull
to remove the data
return this.mobiledashboardModel
.update({"_id": args.dashboardId}, { $pull: {"viewData": { "_id": widgetId}}})
.exec()
.then(dashboardDoc => {
return {
result: dashboardDoc
}
});
The $pull operator removes from an existing array all instances of a value or values that match a specified condition.
The $pull operator has the form:
{ $pull: { <field1>: <value|condition>, <field2>:
<value|condition>, ... } }
To specify a in an embedded document or in an array, use dot notation.
db.stores.update(
{ },
{ $pull: { fruits: { $in: [ "apples", "oranges" ] }, vegetables:
"carrots" } },
{ multi: true }
)
For a single record in array:
db.getCollection('documents').update(
{ },
{'$pull':{ 'items':{'mobile': 1234567890 }}},
{new:true}
);
For a multiple records with same mobile number in array:
db.getCollection('documents').update(
{ },
{'$pull':{ 'items':{'mobile': 1234567890 }}},
{new:true,multi:true}
)
