I'm struggling to update a document and add new elements (fields) into it's existing array without losing the array elements on update.
This is my code which inserts a new document into the collection if it doesn't already exist (upsert):
$updateResult = $collection->findOneAndUpdate(
[
'recording-id' => $out['recording']->id
],
['$set' => [
'release' => [
'id' => $out['release']->id,
'title' => $out['release']->title,
'date' => $out['release']->date,
'country' => $out['release']->country
],
'artist' => [
'id' => $out['artist']->id,
'name' => $out['artist']->name,
],
'recording' => [
'id' => $out['recording']->id,
'title' => $out['recording']->title,
'score' => $out['recording']->score,
'length' => $out['recording']->length,
'release-count' => count($out['recording']->releases),
],
'release-group' => [
'id' => $out['release-group']['id'],
'title' => $out['release-group']['title'],
'first-release-date'=>$out['release-group']['first-release-date'],
'primary-type' => $out['release-group']['primary-type'],
'musicbrainz' => $out['release-group']['musicbrainz'],
'url-rels' => $out['release-group']['url-rels'],
'coverart' => $out['release-group']['coverart']
],
'execution' => [
'firstfind' => $out['execution']->time
]
]
],
['upsert' => true,
'projection' =>
[
'_id' => 0,
'release' => 1,
'artist' => 1,
'recording' => 1,
'release-group' => 1,
'execution' => 1
],
'returnDocument' => MongoDB\Operation\FindOneAndUpdate::RETURN_DOCUMENT_AFTER,
]
);
So now I have an existing document in a collection:
{
"_id" : ObjectId("5d1a6aaf5ecc8001ee858f6c"),
"recording-id" : "d0d439f9-5324-4728-8706-2da39adb89c5",
"artist" : {
"id" : "9d97b077-b28d-4ba8-a3d9-c71926e3b2b6",
"name" : "Gordon Lightfoot"
},
"recording" : {
"id" : "d0d439f9-5324-4728-8706-2da39adb89c5",
"title" : "Sundown",
"score" : 100,
"length" : 184000,
"release-count" : 2
},
"release" : {
"id" : "0c008d76-2bc9-44a3-854b-0a08cde89337",
"title" : "All Live",
"date" : "2012-04-24",
"country" : "CA"
},
"release-group" : {
"id" : "0a5d5f33-8e9d-4fa4-b622-a95e4218a3c4",
"title" : "All Live",
"first-release-date" : "2012-04-24",
"primary-type" : "Album",
"musicbrainz" : "https://musicbrainz.org/release-group/0a5d5f33-8e9d-4fa4-b622-a95e4218a3c4",
"url-rels" : "https://musicbrainz.org/ws/2/release-group/0a5d5f33-8e9d-4fa4-b622-a95e4218a3c4?inc=url-rels&fmt=json",
"coverart" : null
}
}
Now, I would like to update this document, and add new fields into the arrays. The new fields are to be added to certain fields.
Here is the code doing that:
$collection = (new MongoDB\Client)->stream->musicbrainz;
$updateResult = $collection->updateOne(
[
'recording-id' => $out['recording']['id']
],
['$addToSet' => [
'artist' => [
'wikiQiD' => $out['artist']['qid'],
'wiki-extract' => $out['artist']['wiki-extract'],
'wiki-pageid' => $out['artist']['pageid'],
],
'release-group' => [
'wikiQiD' => $out['release-group']['qid'],
'wiki-extract' => $out['release-group']['wiki-extract']
]
]
],
[
'upsert' => true,
'returnDocument' => MongoDB\Operation\FindOneAndUpdate::RETURN_DOCUMENT_AFTER,
]
);
I've noticed there's "$addToSet" and "$push" commands, and could use assistance with what the difference is between these two commands.
If the field is absent in the document to update, $push adds the array
field with the value as its element.
The $addToSet operator adds a value to an array unless the value is
already present, in which case $addToSet does nothing to that array.
I did some googling, and reading of the MongoDB/Client UpdateOne function, but can't seem to find a way to append these fields to the existing arrays.
The error I'm getting is:
Fatal error: Uncaught MongoDB\Driver\Exception\BulkWriteException: The field 'artist' must be an array but is of type object in document {_id: ObjectId('5d1a6aaf5ecc8001ee858f6c')} in ...
I know the following:
It could be my document, as it's not a proper array that Fatal error is complaining about.
It could be my `findOneAndUpdate' formatting, and I'm not doing that correctly.
It could be both and I have it all wrong from the very start.
Any insight or constructive criticism is appreciated, just refrain from flames, pls.
Here's the working code I finally use to get it do what I want it to.
It's a simple matter of just setting your field names and values and mongo will update the found record replacing it with the array sent to it. No need to push or anything.
function firstFindMongoUpdate($out) {
$collection = (new MongoDB\Client)->stream->musicbrainz;
$updateResult = $collection->findOneAndUpdate(
[
'recording-id' => $out['recording']->id
],
['$set' => [
'query' => $out['query'],
'release' => [
'id' => $out['release']->id,
'title' => $out['release']->title,
'date' => $out['release']->date,
'country' => $out['release']->country,
'label' => $out['release']->label,
],
'artist' => [
'id' => $out['artist']->id,
'name' => $out['artist']->name,
'wiki' => $out['artist']->wiki,
],
'recording' => [
'id' => $out['recording']->id,
'title' => $out['recording']->title, // sometimes contains apostophe ie; Bill‘s Love (option ] key)
'score' => $out['recording']->score,
'length' => $out['recording']->length,
'release-count' => count($out['recording']->releases)
],
'release-group' => [
'id' => $out['release-group']['id'],
'title' => $out['release-group']['title'],
'first-release-date'=>$out['release-group']['first-release-date'],
'primary-type' => $out['release-group']['primary-type'],
'musicbrainz' => $out['release-group']['musicbrainz'],
'url-rels' => $out['release-group']['url-rels'],
'coverart' => $out['release-group']['coverart'],
'wiki' => $out['release-group']['wiki']
],
'execution' => [
'artistQuery' => $out['execution']->artistQuery,
'recordingQuery'=> $out['execution']->recordingQuery,
'time' => $out['execution']->time
]
]
],
['upsert' => true,
'projection' =>
[
'_id' => 1,
'query' => 1,
'release' => 1,
'artist' => 1,

);
I am trying to implement the suggest function of elasticsearch-php client in my API to suggest people some already existing problems.
I have made index for my problems
'index' => 'newproblemindex',
'body' => [
'settings' => [
'number_of_shards' => 3,
'number_of_replicas' => 2
],
'mappings' => [
'newproblems' => [ // type of index
'_source' => [
'enabled' => true
],
'properties' => [
'title' => [
'type' => 'text',
'analyzer' => 'standard'
],
'description' => [
'type' => 'text',
'analyzer' => 'standard'
], 'suggest' => [
'type' => 'completion'
]
]
]
]
]
But I am unable to find which param fields to use to implement suggest function
'index' => 'newproblemindex',
'body' => [
'try' => [
'text' => $request->search_key,
'completion' => [ 'text' => 'suggest' ]
]
],
I am using laravel and taking search_key as request param but I am getting "invalid_type_name_exception" and when I tried to give the type name, it is again giving me some error.
"suggest" => [
"song-suggest" => [
"prefix" => $request->search_key,
"completion" => ["field" => "suggest"]
]
]
I am getting error "suggest is not a valid param ". Please help
and Thanks in advance.
I am using ES php library. Here is what i have tried...
$params = [
'index' => 'tasks',
'body' => [
'settings' => [
'number_of_shards' => 3,
'number_of_replicas' => 2
],
'mappings' => [
'all' => [
'_source' => [
'enabled' => true
],
'properties' => [
'task' => [
'type' => 'string',
'analyzer' => 'standard'
],
'to' => [
'type' => 'string',
'analyzer' => 'standard'
],
'category' => [
'type' => 'integer',
'analyzer' => 'keyword'
]
]
]
]
]
];
// Create the index with mappings and settings now
$response = $client->indices()->create($params);
It returns success.
Now when i try to index a document...
$params = [
'index' => 'tasks',
'type' => 'all',
'id' => 'some_id',
'body' => [ 'task' => 'some test', 'to' => 'name', 'category' => 1]
];
$response = $client->index($params);
This throws error and does not work, however it works If i try this without creating index and mapping first.
Please suggest. Thanks
It's wrong to define analyzer in a field of type 'integer'.
Trying to create this mapping through Elasticsearch-PHP gives me a bad request:
... "reason":"Mapping definition for [category] has unsupported parameters: [analyzer : keyword]"}},"status":400}
Trying to create this mapping directly via PUT to ES gives me same error
I'm using ES version 2.2.0 and Elasticsearch-PHP 2.0
I am trying to find a document using ElasticSearch and update a field in it. The code is:
require_once 'vendor/autoload.php';
$client = Elasticsearch\ClientBuilder::create()->build();
$params = [
'index' => 'myIndex',
'type' => 'myCollection',
'body' => [
'query'=> [
'match'=> [
'accessToken' => $accessToken
]
] ,
'script' => 'ctx._source.deviceId= deviceId',
'params' => [
'deviceId' => $deviceId
],
'upsert' => [
'counter' => 1
]
]
];
The code is giving 500 Internal Error. Any idea what am I missing?
If you want to increase the value of deviceid by 1 (mean if value of deviceid is 4 then u can increase it to 5 by adding 1 to it ),then follow below code
'script' => 'ctx._source.deviceId= deviceId',
replace with
'script' => 'ctx._source.counter += deviceId',
Example:
$params = [
'index' => 'my_index',
'type' => 'my_type',
'id' => 'my_id',
'body' => [
'script' => 'ctx._source.counter += count',
'params' => [
'count' => 4
],
'upsert' => [
'counter' => 1
]
]
];
$response = $client->update($params);
Check i Elasticsearch php
I have a CollectionSet<UDT> where UDT contains a CollectionMap<int,boolean>. I have not been able to find any documentation or example of how to define this when creating a new Cassandra\Type\CollectionSet for inserting into the table. There is a great example with a CollectionList (found here) which is like this:
// CollectionSet<UDT>, where UDT contains: Int, Text, Boolean,
// CollectionList<Text>, CollectionList<UDT>
new Cassandra\Type\CollectionSet([
[
'id' => 1,
'name' => 'string',
'active' => true,
'friends' => ['string1', 'string2', 'string3'],
'drinks' => [['qty' => 5, 'brand' => 'Pepsi'], ['qty' => 3, 'brand' => 'Coke']]
],[
'id' => 2,
'name' => 'string',
'active' => false,
'friends' => ['string4', 'string5', 'string6'],
'drinks' => []
]
], [
[
'type' => Cassandra\Type\Base::UDT,
'definition' => [
'id' => Cassandra\Type\Base::INT,
'name' => Cassandra\Type\Base::VARCHAR,
'active' => Cassandra\Type\Base::BOOLEAN,
'friends' => [
'type' => Cassandra\Type\Base::COLLECTION_LIST,
'value' => Cassandra\Type\Base::VARCHAR
],
'drinks' => [
'type' => Cassandra\Type\Base::COLLECTION_LIST,
'value' => [
'type' => Cassandra\Type\Base::UDT,
'typeMap' => [
'qty' => Cassandra\Type\Base::INT,
'brand' => Cassandra\Type\Base::VARCHAR
]
]
]
]
]
]);
I've tried using the above example with several variations to accommodate the CollectionMap but nothing is working. My last attempt was this
new Cassandra\Type\CollectionSet($udt_array, [[
'type'=>Cassandra\Type\Base::UDT,
'definition' => [
'map_name' => [
'type' => Cassandra\Type\Base::COLLECTION_MAP,
'value' => [
Cassandra\Type\Base::INT,
Cassandra\Type\Base::BOOLEAN
]
]
]
]])
which gives the error Caught exception: Since v0.7, collection types should have \"definition\" directive. I've also tried using 'definition' instead of 'value'. I'm running out of ideas, any help would be greatly appreciated.
Use "definition" instead of "value". I tried this before but apparently I was doing something else wrong because this worked.
new Cassandra\Type\CollectionSet($udt_array, [[
'type'=>Cassandra\Type\Base::UDT,
'definition' => [
'map_name' => [
'type' => Cassandra\Type\Base::COLLECTION_MAP,
'definition' => [
Cassandra\Type\Base::INT,
Cassandra\Type\Base::BOOLEAN
]
]
]
]])
