I have this structure:
{
"user" => "xxxx",
"position" =>
{
"A1" => { "state" => 'It', region=>"LOM" etc etc..},
"A2" => { .... },
"A3" => { .... },
....
"An" => { .. }
}
}
insert is ok. but update return this error:
not a reference at /usr/local/lib/perl/5.12.4/MongoDB/Collection.pm line 376
My update is:
$tbl->update({
{ _id => MongoDB::OID->new(value => "$id") },
{ '$set' =>
{
"position" =>
{
"A1" => { "state" => "En" }
}
}
}
});
Where I wrong?
Thks!
I check syntax of update source of MongoDB::Collection
syntax update
update (\%criteria, \%object, \%options?)
inside MongoDB::Collection method update
sub update {
my ($self, $query, $object, $opts) = #_;
...
}
but you pass only 1 parameter.
$tbl->update(
{ # 1st anonymous hash
{ _id => MongoDB::OID->new(value => "$id") },
{ '$set' => {
"position" => {
"A1" => { "state" => "En" }
}
}
}
});
So I advice you figure out with passed parameters to method update.

I am trying to push values into hash. I want to add the values under 'par3'.
e.g.
$VAR1 = { 'obj1' => ['par1',
'par2',
'par3' => ['par4','par5','par6',....]]}
I should also be able to add elements into 'par3' in case 'obj1'-'par1'-'par2'-'par3' matches.
So far I have this, but I can't figure out how can I add "the second level" under 'par3':
push #{$a{$obj}},$par1,$par2,$par3
[ ... ] is a reference to an array. Array elements are scalars. So it is not possible to directly have the structure you seem to be requesting (ie. the par3 => [ ... ] pseudocode from your question). See perldsc
It's not obvious what you are trying to do but a couple of possible ideas might be to use a reference to a hash, or to replace the array with a hash:
use Data::Dumper;
$Var2a = {
'obj1' => [
'par1',
'par2',
{ 'par3' => undef, }
],
};
push #{ $Var2a->{obj1}[2]{par3} }, 'par4', 'par5', 'par6';
print Dumper $Var2a;
$Var2b = {
'obj1' => {
'par1' => undef,
'par2' => undef,
'par3' => undef,
},
};
push #{ $Var2b->{obj1}{par3} }, 'par4', 'par5', 'par6';
print Dumper $Var2b;
I think you want to add children to par3. As such, I think you want pars to have children. If so, you need a different data structure.
# Ordered
my $obj1 = [
{ name => 'par1', children => [ ] },
{ name => 'par2', children => [ ] },
{ name => 'par3', children => [
{ name => 'par4', children => [ ] },
{ name => 'par5', children => [ ] },
{ name => 'par6', children => [ ] },
] },
];
or
# Unordered
my $obj1 = {
par1 => { },
par2 => { },
par3 => {
par4 => { },
par5 => { },
par6 => { },
},
};
To append par7 to par3's children, you would use
# Ordered
use List::Util qw( first );
my $par7 = { name => 'par7', children => [ ] };
my $par3 = first { $_->{ name } eq 'par3' } #$obj1
or die( "par3 not found" );
push #{ $par3->{ children } }, $par7;
or
# Unordered
$obj1->{ par3 }{ par7 } = { };
db.getCollection('Subscriber').find({$and:[{"registerFrom":{$exists:false}},{"googleRegistrationId":{$exists:true}},{"isGuest":"false"}]})
how to write the above query in Perl please help this.I am getting different results on this when execute on perl
i have written like this in perl
my $Subscriber2 = $Subscriber->find({'$and' =>[{dateOfJoining => {'$gt' => $date}},{registerFrom => { '$exists' => 'false'}},{googleRegistrationId => {'$exists' => 'true'}},{isGuest => 'false'}]})->fields({ _id => 1,streamzCampaigns => 1});
I am not getting the same results as when executing in perl.How to use $exits of mongoDB in Perl.Please help on this one.
The two suspicious bits I see are that you've quoted "true" and "false" -- which make those strings, not boolean values -- and I wonder what you're using for $date, since you don't have that in your shell example.
Here is what you wrote, formatted nicely:
my $Subscriber2 = $Subscriber->find(
{
'$and' => [
{ dateOfJoining => { '$gt' => $date } },
{ registerFrom => { '$exists' => 'false' } },
{ googleRegistrationId => { '$exists' => 'true' } },
{ isGuest => 'false' }
]
}
)->fields( { _id => 1, streamzCampaigns => 1 } );
For the booleans, you should use the boolean.pm module:
use boolean;
my $Subscriber2 = $Subscriber->find(
{
'$and' => [
{ dateOfJoining => { '$gt' => $date } },
{ registerFrom => { '$exists' => false } },
{ googleRegistrationId => { '$exists' => true } },
{ isGuest => false }
]
}
)->fields( { _id => 1, streamzCampaigns => 1 } );
As the title suggests, I am upgrading to ES5. My original ES query looked like:
my $response = $elastic->do_request_new(
{
query => {
filtered => {
filter => {
or => [
{ term => { _type => { value => "some_val1" } } },
{ term => { _type => { value => "some_val2" } } },
]
},
query => {
query_string => {
query => $qstring,
rewrite => "scoring_boolean",
analyze_wildcard => "true",
}
}
}
},
sort => [ qw(_score) ],
size => 50,
},
);
My updated looks like:
my $response = $elastic->do_request_new(
{
query => {
bool => {
should => [
{ term => { _type => { value => "some_val1" } } },
{ term => { _type => { value => "some_val2" } } },
],
must => {
query_string => {
query => $qstring,
rewrite => "scoring_boolean",
analyze_wildcard => "true",
}
}
}
},
sort => [ qw(_score) ],
size => 50,
},
);
However, upon searching for exact strings in my elastic database, I am returning zero results:
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
Any ideas about what might be happening? My guess is I have my query structure wrong. Thanks!
Update: The following fixed query:
my $response = $elastic->do_request_new(
{
query => {
bool => {
must => [
{
query_string => {
query => $qstring,
rewrite => "scoring_boolean",
analyze_wildcard => "true",
},
}
],
filter => {
bool => {
should => [
{ term => { _type => { value => "some_val1" } } },
{ term => { _type => { value => "some_val2" } } },
],
},
},
},
},
sort => [ qw(_score) ],
size => 50,
},
);
Unfortunately, I cannot use positional operators since there is a bug that doesn't allow deeper than 1 embedded document: https://jira.mongodb.org/browse/SERVER-831
So this wont work (using the Mongodb Ruby driver):
stat_profile.update({ profile_id: profile.id, providers: { '$elemMatch' => { provider_name: 'foo', dates: { '$elemMatch' => { date: 20130911, relationships: { '$elemMatch' => { relationship_type: 'friend' } } } } } } },
{ '$set' => { 'providers.$.dates.$.relationships.$.ids' => [1,2,3] } })
Given the following collection. Relationships is embedded in dates, dates is embedded in providers.
How do I update the ids field?
{
"_id" => BSON::ObjectId('523048983858f61767000008'),
"profile_id" => 3,
"providers" => [
[0] {
"provider_name" => "foo",
"dates" => [
[0] {
"date" => 20130911,
"relationships" => [
[0] {
"relationship_type" => "acquaintance",
"count" => 0
},
[1] {
"relationship_type" => "friend",
"count" => 0,
"males_count" => 0,
"females_count" => 0,
"top_ten_countries" => [],
"ids" => []
}
]
}
]
}
]
}

You said you wanted
detailed -> doc -> params -> parameters -> name
but that's missing many indexes. Which doc, param and parameters do you want?
detailed -> doc -> ??? -> params -> ??? -> parameters -> ??? -> name
The syntax is:
$member->{detailed}->{doc}->[$i]->{params}->[$j]->{parameters}->[$k]->{name}
Or for short:
$member->{detailed}{doc}[$i]{params}[$j]{parameters}[$k]{name}
If you want to loop over every doc, params, parameter, you can use:
my $docs = $member->{detailed}{doc};
for my $doc (#$docs) {
my $params = $doc->{params};
for my $param (#$params) {
my $parameters = $param->{parameters};
for my $parameter (#$parameters) {
...
}
}
}
(Why is doc singular and params and parameters plural??? Why do params have parameters???)
