Is it possible to send data contained in postgres to dashing dashboard? I have found mysql example here and same question here.
I edited my job in jobs folder. I have also included pg gem.
require 'pg'
conn = PGconn.new(:host => "10.10.8.10", :port => "5432",:dbname => "db1",:login => "test",:password => "test")
results = conn.exec("select partner,sitetype from test")
# Sending to List widget, so map to :label and :value
acctitems = results.map do |row|
row = {
:label => row['partner'],
:value => row['sitetype']
}
end
# Update the List widget
send_event('account_count', { items: acctitems } )
end
Include in Gemfile :
gem 'pg'
In your jobs.rb file:
require 'pg'
SCHEDULER.every '3m', :first_in => 0 do |job|
conn = PGconn.new(:host => "localhost", :port => "5432",:dbname => "dbname",:user => "test",:password => "test")
results = conn.exec("select partner,sitetype from test")
# Sending to List widget, so map to :label and :value
acctitems = results.map do |row|
row = {
:label => row['partner'],
:value => row['sitetype']
}
end
# Update the List widget
send_event('account_count', { items: acctitems } )
end

In my program, I have a section of code that updates a list box depending on the value of another list box.
The code that does this looks a little like this.
$listBox1->bind('<<ListboxSelect>>' => sub {
$listBox2->delete(0, 'end');
for(#{$hashOfArraysOfStruct{$listBox1->get($listBox1->curselection)}}) {
$listBox2->insert('end', $_->name);
}
});
This works fine. However, I have found it easier to simply use a list and manipulate the list on the <<ListboxSelect>>. I have bound this list to the list box using -listvariable.
The code to do this looks a bit like
$listBox1->bind('<<ListboxSelect>>' => sub {
#updateableList = #{$hashOfArraysOfStruct{$listBox1->get($listBox1->curselection)}};
});
The problem with this approach is, as hashOfArraysOfStruct, contains structures, the list box contains values such as MyStruct=HASH(0x31d7e3c).
Is there any way to display the name variable of the struct MyStruct without looping through the whole array and individually inserting each result into the list box?

I have already created a course using moodle RestAPI(function name : core_course_create_courses). then i want to upload a scorm package in moodle course module/activity.
i have write some code for that,this code will create a module in that course. i don't know how to upload scorm package in that course module.
here is my code
Add function core_course_create_modules in lib/db/services.php at line no : 327
'core_course_create_modules' => array(
'classname' => 'core_course_external',

'classpath' => 'course/externallib.php',
'description' => 'Creates modules in a course',
'type' => 'write',
'capabilities' => 'moodle/course:manageactivities',
)
Add 3 method in Courses/externallib.php file
2.1)create_modules_parameters
=> `public static function create_modules_parameters() {
$courseconfig = get_config('moodlecourse'); //needed for many default values

as per above code ,
its take name field as a scorm packages, in the admin side its display name as a scorm, when i was click on that its display errors:
screenshot for error
so, i don't know how to upload scorm package in course module using moodle Rest api, how can i do ?
Thank you.
I have a search form for searching "documents", that have a small dozen of search criterions, including "entire_text", "keywords" and "description".
I'm using pg_search_scope, but I have 2 different scopes.
This is in my document.rb:
pg_search_scope :search_entire_text,
:against => :entire_text,
:using => {
:tsearch => {
:prefix => true,
:dictionary => "french"
}
}
pg_search_scope :search_keywords,
:associated_against => {
:keywords => [:keyword]
},
:using => {
:tsearch => {
:any_word => true
}
}
Each separately works fine. But I can't do this:
#resultats = Document.search_keywords(params[:ch_document][:keywords]).search_entire_text(params[:ch_document][:entire_text])
Is there any way to work around this?
Thanks
I've never used pg_search_scope but it looks like you indeed can't combine two pg_search_scope's.
What you could do is use :search_entire_text with a pg_search_scope and use the resulting id's in a Document.where([1,2,3]) that way you can use standard rails scope's for the remaining keyword searches.
Example:
# If pluck doesn't work you can also use map(&:id)
txt_res_ids = Document.search_entire_text(params[:ch_document][:entire_text]).pluck(:id)
final_results = Document.where(id: txt_res_ids).some_keyword_scope.all
It works. Here's the entire code ... if ever this could help someone :
Acte.rb (I didn't translate to english, the explanations are commented to correspond to the question above)
pg_search_scope :cherche_texte_complet, #i.e. find entire text
:against => :texte_complet,
:using => {
:tsearch => {
:prefix => true,
:dictionary => "french"
}
}
pg_search_scope :cherche_mots_clefs, #find keywords
:associated_against => {
:motclefs => [:motcle]
},
:using => {
:tsearch => {
:any_word => true
}
}
def self.cherche_date(debut, fin) #find date between
where("acte_date BETWEEN :date_debut AND :date_fin", {date_debut: debut, date_fin: fin})
end
def self.cherche_mots(mots)
if mots.present? #the if ... else is necessary, see controller.rb
cherche_mots_clefs(mots)
else
order("id DESC")
end
end
def self.ids_texte_compl(ids)
if ids.any?
where("id = any (array #{ids})")
else
where("id IS NOT NULL")
end
end
and actes_controller.rb
ids = Acte.cherche_texte_complet(params[:ch_acte][:texte_complet]).pluck(:id)
#resultats = Acte.cherche_date(params[:ch_acte][:date_debut],params[:ch_acte][:date_fin])
.ids_texte_compl(ids)
.cherche_mots(params[:ch_acte][:mots])
Thanks !
chaining works in pg_search 2.3.2 at least
SomeModel.pg_search_based_scope("abc").pg_search_based_scope("xyz")
I'm using Search::Elasticsearch to query MetaCPAN.
my $es = Search::Elasticsearch->new(
cxn_pool => 'Static::NoPing',
nodes => 'api.metacpan.org:80',
);
my $scroller = $es->scroll_helper(
index => 'v0',
type => 'release',
search_type => 'scan',
scroll => '2m',
size => $size,
body => {
fields => [qw(author archive date)],
query => { range => { date => { gte => $date } } },
},
);
This works ok, but I'd like to set the HTTP User-Agent header to a custom value so my requests can be identified if there's a problem. How do I do that with Search::Elasticsearch?
You can pass arguments to the handle constructor using handle_args. So for the default HTTP::Tiny you would use agent:
my $es = Search::Elasticsearch->new(
cxn_pool => 'Static::NoPing',
nodes => 'api.metacpan.org:80',
handle_args => { agent => "youragent/0.1" },
);
I want to check for an existing record by matching either title or url fields. If either one matches, update that record. Otherwise, insert.
How do write the following properly (using Mongoid in Ruby):
articles.update(
{ **:title => story.title OR :url => story.url** },
{ :title => story.title, :url => story.url, :source => story.source, :last_updated => Time.now },
{ :upsert => true } )
Thanks!
You need do the request and update it like :
'''
articles.any_of({:title => xxx}, {:url => yyyy}).update( :foo => 'bar')
'''
