Using a string as a RID with SQL Commands - orientdb

Using the Java api on an Orient-DB 2.0 rc1. Is it possible to use a string as a RID?
Documentation : https://github.com/orientechnologies/orientdb/wiki/SQL-Update#example-3-add-a-value-into-a-collection
more specifiaclly the section SQL Commands
JSON received:
{
userRID:"#100:100",
group:"someCode"
}
JAVA CODE (xtend script):
def addUserInGroup(Message<JsonObject> message){
val params = new JsonObject() => [
putString("userId", message.body().getString("userRID"));
putString("code", message.body().getString("group"));
]
var queryCommand= "update Table add users=:userId where code=:code";
Map<String, Object> paramsFormatted = params.toMap();
database.command( new OCommandSQL(queryCommand) ).execute(paramsFormatted);
}
Table structure :
users : linklist (user object)
code : string
When I run the following commands in the studio they all work :
update Table add users=(Select #rid from User where #rid=#100:100) where code='someCode'
update Table add users=#100:100 where code='someCode'
But none of these command work in the API. I'm guessing there is something wrong in way I'm using the RID.

I think You should try something like :
putString("userId", new ORecordId(message.body().getString("userRID")));

Asterisk-Java Unable to load Properties file

I'm developing a very simple Asterisk-Java IVR based program that greets the caller, retrieves some information from a web service, reads up the retrieved data to the caller, and finally hangs up.
What steps I followed:
Added the following line is entered on extensions_custom.conf:
exten => 1000,n,Agi(agi://192.168.0.8/ivryobi.agi)
Created the following file structure inside C:\Project\target\classes\
Runnable.java
IvrYobi.java
Runnable.class
IvrYobi.class
fastagi-mapping.properties
Inside fastagi-mapping.properties I have:
ivryobi.agi = main.IvrYobi
The contens of IvrYoby are:
public class IvrYobi extends BaseAgiScript {
public void service(AgiRequest request, AgiChannel channel) throws AgiException {
String callerMsisdn = request.getCallerIdNumber();
}
When it works normally
Running the following command in the console
C:\Project\target\classes>java -cp
asterisk-java.jar;commons-lang3-3.10.jar;commons-logging-1.2.jar;httpclient-4.5.12.jar;httpcore-4.4.13.jar;mysql-connector-java-8.0.20.jar;.
org.asteriskjava.fastagi.DefaultAgiServer
As you can see on the following console output, works perfectly
jun 30, 2020 6:09:04 PM org.asteriskjava.fastagi.DefaultAgiServer
startup INFORMACIËN: Listening on *:4573. jun 30, 2020 6:09:09 PM

org.asteriskjava.fastagi.ResourceBundleMappingStrategy
loadResourceBundle INFORMACIËN: Added mapping for 'ivryobi.agi' to
class IvrYobi ...
When the problem appears
When I run the very same code, but insted of the console I use Runnable.java
Here are the contents of Runnable.java:
DefaultAgiServer server = new DefaultAgiServer();
public MyRunnable() {
ClassNameMappingStrategy strategy = new ClassNameMappingStrategy(false);
server.setMappingStrategy(strategy);
}
public void run() {
try {
server.startup();
} catch (IllegalStateException | IOException e) {
e.printStackTrace();
server.shutdown();
}
}
public void stop() {
server.shutdown();
}
We can observe the following error on Eclipse's console:
0 [main] DEBUG org.asteriskjava.fastagi.DefaultAgiServer - Using

Attempted troubleshooting
I already made sure that fastagi-mapping.properties is on the CLASSPATH.
Tried different name and case
Copied the .properties file on the java Execution Path
Compiled the project as an executable jar
Added / removed packages inside eclipse (ex: com.test.IvrYobi) and also applied the changes on the .properties file.
I checked the code inside asterisk-java-3.5.0.jar, looks like that in case that the configuration file is not found, it just continues without throwing any warning. Since is packed inside the jar I'm unable to modify that code.
Please, do you have any other ideas I can try?
Finally found the solution by myself
I had to recompile asterisk-java.jar using the project's source code
On DefaultAgiServer.java change the line:
resourceBundle = ResourceBundle.getBundle(configResourceBundleName);
With:
FileInputStream fis = new FileInputStream("myivr.properties");
resourceBundle = new PropertyResourceBundle(fis);
logger.info("resourceBundle cargado ok!");
On the catch, replace the
return;
with a more decent response, so you will know if the resource could not be loaded
logger.info("resourceBundle cargado ok!");
}
catch (MissingResourceException | IOException e)
{
logger.error("No existe el recurso invocado: " + e.getMessage());
return;
}

ReactiveMongo/Play: `LastError: DatabaseException['<none>']`, while db still updates

weird problem: While my play application tries to insert/update records from some mongoDB collections while using reactivemongo, the operation seems to fail with a mysterious message, but the record does, actually, gets inserted/updated.
More info:
Insert to problematic collections from the mongo console works well
reading from all collections works well
reading and writing to other collections in the same db works well
writing to the problematic collections used to work.
Error message is:

Thanks!
UPDATE - The mystery thickens!
Based on #Yaroslav_Derman's answer, I added a .recover clause, like so:
collectionRef.flatMap( c =>
c.update( BSONDocument("_id" -> publicationWithId.id.get), publicationWithId.asInstanceOf[PublicationItem], upsert=true))
.map(wr => {
Logger.warn("Write Result: " + wr )
Logger.warn("wr.inError: " + wr.inError)
Logger.warn("*************")
publicationWithId
}).recover({
case de:DatabaseException => {
Logger.warn("DatabaseException: " + de.getMessage())
Logger.warn("Cause: " + de.getCause())
Logger.warn("Code: " + de.code)
publicationWithId
}
})
The recover clause does get called. Here's the log:
[info] application - Saving pub t3
[warn] application - *************
[warn] application - Saving publication Publication(Some(BSONObjectID("5848101d7263468d01ff390d")),t3,2016-12-07,desc,auth,filename,None)
[info] application - Resolving database...
[info] application - Resolving database...
[warn] application - DatabaseException: DatabaseException['<none>']
[warn] application - Cause: null
[warn] application - Code: None
So no cause, no code, message is "'<none>'", but still an error. What gives?
I tried to move to 0.12, but that caused some compilation errors across the app, plus I'm not sure that would solve the problem. So I'd like to understand what's wrong first.
UPDATE #2:
Migrated to reactive-mongo 0.12.0. Problem persists.
Problem solved by downgrading to MongoDB 3.2.8. Turns out reactiveMongo 0.12.0 is not compatible with mongoDB 3.4.
Thanks everyone who looked into this.
For play reactivemongo 0.12.0 you can do like this
def appsDb = reactiveMongoApi.database.map(_.collection[JSONCollection](DesktopApp.COLLECTION_NAME))
def save(id: String, user: User, body: JsValue) = {
val version = (body \ "version").as[String]
val app = DesktopApp(id, version, user)
appsDb.flatMap(
_.insert(app)
.map(_ => app)
.recover(processError)
)
}
def processError[T]: PartialFunction[Throwable, T] = {
case ex: DatabaseException if ex.code.contains(10054 | 10056 | 10058 | 10107 | 13435 | 13436) =>
//Custom exception which processed in Error Handler
throw new AppException(ResponseCode.ALREADY_EXISTS, "Entity already exists")
case ex: DatabaseException if ex.code.contains(10057 | 15845 | 16550) =>
//Custom exception which processed in Error Handler
throw new AppException(ResponseCode.ENTITY_NOT_FOUND, "Entity not found")
case ex: Exception =>
//Custom exception which processed in Error Handler
throw new InternalServerErrorException(ex.getMessage)
}
Also you can add logs in processError method
LastError was deprecated in 0.11, replaced by WriteResult.
LastError does not, actually, means error, it could mean successful result, you need to check inError property of the LastError object to detect if it's real error. As I see, the '<none>' error message give a good chance that this is not error.
Here is the example "how it was in 0.10": http://reactivemongo.org/releases/0.10/documentation/tutorial/write-documents.html

How to pass an object dynamically in the define function of Ext object in Sencha ExtJS 6.0.2?

Taking a look at the following segment of code you will see two cases where the sencha cmd return an error and one case that it doesn't
var memoryStore = new MemoryStore<Individual>("personnel", [
'name', 'email', 'phone'
], [
new Individual("Batman", "etsigoustaro#thefirm.com", "+306969696969"),
new Individual("Jean Luc", "jeanluc.picard#enterprise.com", "555-111-1111"),
new Individual("Worf", "worf.moghsson#enterprise.com", "+30 696 969 6969"),
new Individual("Deanna", "mr.data#enterprise.com", "+30 6969696969"),
new Individual("Data", "deanna.troi#enterprise.com", "+30-6969696969"),
])
//memoryStore.toExtJS()
Ext.define('extTestTs.store.Personnel', (function(){
//return JSON.stringify(memoryStore.toExtJS()) //fails
//return Ext.Object.merge({},{}) //fails
return {} //succeeds
})());
As you see we have removed everything, even extends is missing but as long as you are typing an object by hand it works. When this object is returned from a function it stops to work!
What does the sencha cmd does behind the scenes? Is it parsing the plain javascript as a text file?..
Because if it was javascript it would run without an issue.
This is the error from sencha cmd console output:
[ERR] C2008: Requirement had no matching files (extTestTs.store.Personnel) -- /home/student/Desktop/Typescript/extTestTs/classic/src/view/main/List.js:8:10
[ERR]
[ERR] BUILD FAILED

How could we overcome this restriction of explicitly defining the object and rather define it more dynamically?
The goal is to make typescript work with ExtJS but not with the extreme unconventional solutions others propose, like forking typescript itself
Found a workaround
First allow unreachable code in typescript
Here is a screenshot from the IntelliJ settings:
And the code in the questions transforms into that
var memoryStore = new MemoryStore<Individual>("personnel", [
'name', 'email', 'phone'
], [
new Individual("Batman", "etsigoustaro#thefirm.com", "+306969696969"),
new Individual("Jean Luc", "jeanluc.picard#enterprise.com", "555-111-1111"),
new Individual("Worf", "worf.moghsson#enterprise.com", "+30 696 969 6969"),
new Individual("Deanna", "mr.data#enterprise.com", "+30 6969696969"),
new Individual("Data", "deanna.troi#enterprise.com", "+30-6969696969"),
])
//memoryStore.toExtJS()
Ext.define('extTestTs.store.Personnel', function (Personnel) {
return memoryStore.toExtJS()
return {} //do not erase this line
});
Yeah the line return {} might seem totally redundant but (obviously) the sencha cmd is trying to parse the file before it includes it in the requires
Now sencha cmd gives a success and executing sencha app web start the sample app works ok

org.postgresql.util.PSQLException: No results returned by the query

hey everyone am trying to insert data in a table using #Query annotation in my spring boot app am getting a postgres Exception :
org.postgresql.util.PSQLException: No results returned by the query
this is my code :
this is the repository
#Query(value="INSERT INTO \"FCT_BY_DEV\"(\"IdDev\", \"IdFonction\") VALUES (?, ?) ",nativeQuery=true)
public String isertfonctionstodev(int dev,int fonction);
this is the controller :
#RequestMapping(value="/function/insert", method = RequestMethod.POST)
public String insererfonctions (int dev,int fonction){
System.out.println("dev="+dev+"fonction="+fonction);
fonctionRepository.isertfonctionstodev(dev, fonction);
System.out.println("********");
return "aaa";
}
am using this service by $http in angularJs
$http.post("/function/insert?dev="+$scope.id+"&fonction="+$scope.idf);
and finaly this is the server log
dev=16006fonction=14
Hibernate: INSERT INTO "FCT_BY_DEV"("IdDev", "IdFonction") VALUES (?, ?)

the data is correct and i tried the same query with the same value and it worked why posgres is generating this exception and how can i fixed , thanks to any help
I think modifying queries must be annotared with an extra
#Modifying
This should solve your issue:
#Transactional
#Modifying(clearAutomatically = true)
#Query(value="update policy.tbl_policy set ac_status = 'INACTIVE' where pol_id = :policyId and version_no = :version_no and ac_status = 'ACTIVE'", nativeQuery=true)
public void updateExistingRowbyId(#Param("policyId") Long pol_id, #Param("version_no") Long version_no);
Without #Transactional annotation, following errors may occur:
javax.persistence.TransactionRequiredException: Executing an update/delete query

Errors in codeigniter-restserver library

I want to use restful in my ci 3.03 application:
I found this tutplus tutorial
I downloaded codeigniter-restserver-master.zip file and copied Format.php and REST_Controller.php(#version 3.0.0) files into /application/libraries/REST directory
I created control application/controllers/api/Users.php :
require_once("application/libraries/REST/REST_Controller.php");
require_once("application/libraries/REST/Format.php");
class Users extends REST_Controller
{
//protected $rest_format = 'json';
function users_get()
{
//$users = $this->user_model->get_all();
$filter_username= $this->get('filter_username');
$filter_user_group= $this->get('filter_user_group');
$filter_active= $this->get('filter_active');
$sort= $this->get('sort');
$sort_direction= $this->get('sort_direction');
//, $filter_user_group, $filter_active, $sort, $sort_direction
$users_list = $this->muser->getUsersList(false, ''/*, $filter_username, $filter_user_group, $filter_active, $sort, $sort_direction, ''*/);
echo '<pre>'.count($users_list).'::$users_lists::'.print_r($users_list,true).'</pre>';
if($users_list)
{
$this->response($users, 200);
}
else
{
$this->response(NULL, 404);
}
}
AND RUNNING URL http://local-ci3.com/api/users I got many errors:

Actually I wanted to get some workable library to help me with REST api creation. I think that is preferable way istead of making from zero.
But is this library not workable or does it needs for some fixing? Sorry, what I missed is if this library only for ci 2?
I made search on this forum and found such hint :
I have the same problem when I load both Format.php and
Rest_Controller.php into a controller. After have a quick glance at
Format.php, it appears to be a standalone format conversion helper.
Try to just load Rest_Controller.php and see if your problem goes
away.
I commented line
//require_once("application/libraries/REST/Format.php");
in my controller, but I still get errors like :
Message: Undefined property: Users::$format.
I tried to review code of this library and see that invalid block when data are converted to json format, line 731-757 :
elseif ($data !== NULL)
{
// If the format method exists, call and return the output in that format
if (method_exists($this->format, 'to_' . $this->response->format))
{
// Set the format header
$this->output->set_content_type($this->_supported_formats[$this->response->format], strtolower($this->config->item('charset')));
$output = $this->format->factory($data)->{'to_' . $this->response->format}();
// An array must be parsed as a string, so as not to cause an array to string error
// Json is the most appropriate form for such a datatype
if ($this->response->format === 'array')
{
$output = $this->format->factory($output)->{'to_json'}();
}
}
else
{
// If an array or object, then parse as a json, so as to be a 'string'
if (is_array($data) || is_object($data))
{
$data = $this->format->factory($data)->{'to_json'}();
}
// Format is not supported, so output the raw data as a string
$output = $data;
}
}
If I tried to commented this block, but get error
Message: Array to string conversion
Looks like data are not converted in this case...
Is is possible to fix these errors?
Or can you, please, to tell me advice some codeigniter 3 REST api workable library with similar interface like library above?
Thanks!
I use that lib, work just fine. My suggestion is follow the more relevant installation instruction on github .
you also wrong place the lib file :
Tutorial say :
require(APPPATH'.libraries/REST_Controller.php');
You try :
require_once("application/libraries/REST/REST_Controller.php");
require_once("application/libraries/REST/Format.php");
No need to include the format because on line 407 the lib will load it. And also good to know on line 404 it will load the configuration (application/config/rest.php) it will be your default configuration, and also you can change it to suit your need.
Please let me know if you still got error using my answer :)
