Inside ScheduleController I call ScheduleTransformer including GroupTransformer. Inside StudentController I call StudentTransformer including GroupTransformer. GroupTransformer availableInclude schedule and students
Once started the server, in postman, I execute:
1-call schedule, return OK, then call student, return error 500.
2-restart server
3-call student, return OK, then call schedule, return error 500.
4-restant server
5-...
error 500: A transformer must be a function or a class extending TransformerAbstract
removing the include in both, no error is shown
Is this error related to some sort of "cross include"?
Windows 10.
I figured out.
A problem or not, here what happens
If transformer A includes B and B includes A, whenever I call one of them, the second start bringing error 500 and the first continue working normally.
the simplest solution is put the importation inside the import, like this:
includeStudents(model) {
const StudentTransformer = use('App/Transformers/StudentTransformer')
return this.collection(model.getRelated('students'), StudentTransformer)
}
instead of up in the top of, as it is usual.

I'm running into issues with allowing a Laravel job to interact with the console output.
At the moment I am passing in the OutputStyle from a Command to the Job constructor and assigning it.
I have seen the InteractsWithIO trait but if I use that by itself without assigning the OutputStyle from the command then it says it is null.
Call to a member function title() on null
I have also tried setting $this->output from the container using
$this->output = resolve(OutputStyle::class);
This fails with a
Target [Symfony\Component\Console\Input\InputInterface] is not instantiable while building [Illuminate\Console\OutputStyle].
I've also ran into issues with PHPUnit tests that run through this job. The output from the class is displayed in the test output.
.......................Processing element 1 for "Section"
.......
What's the best way to handle outputting to the console within Laravel that also works with PHPUnit?
Putting the following code in a Service Provider works:
$this->app->bind('console.output', function () {
return new OutputStyle(
new StringInput(''),
new StreamOutput(fopen('php://stdout', 'w'))
);
});
I am then able to say, in my Job,
$this->output = resolve('console.output');
Which gives access to all the methods such as title, section, and table.
I'm trying to create a program which generates event dates for the whole year. The program works if the user select few events but if the user select 100+ events and assigned them every week it reaches the Maximum execution time error.
In order to fix this, my idea is to run the program in the background.
I'm using Laravel 5.4, running the script below will call the function
$process = new Process('php -f '.$path.' generate_evnt_prepared ' . $content['evntid']);
$process->run();
Function Script
namespace App\Library\shellexec;
use App\Model\V1\EvntPlanDtl;
use App\Model\V1\EvntPlanDtlPrePo;
use Carbon\Carbon;
class RoutePlan {
//put your code here
public function process($method = null, $param = 0)
{
$this->$method($param);
}
I'm pretty sure that the function is called as I'm getting an error in error_logs that the Models are not found
PHP Fatal error: Class 'App\Model\V1\EvntPlanDtl' not found in C:\xampp\htdocs\rdmsoffice\app\Library\shellexec\EventPlan.php on line 30
PHP Stack trace:

PHP 3. App\Library\shellexec\EventPlan->generate_evnt_prepared ()
Anyone knows how to fix this? I'm open to suggestions if this is the wrong way.
Big thanks!
Sounds like a more scalable way is to create a "chunked" version and fire them into a queue for processing. For example, based off some assumptions about the example you provided, I might suggest one firing one queued message for each Event the user selects.
That adds some overhead to manage, but honestly I've always found it's more effective to take some of that cost up front and do it right, rather than finding workarounds like increasing settings or (shudder) shelling out to sub processes.
I made a custom report in AX2012, to replace the WHS Shipping pick list. The custom report is RDP based. I have no trouble running it directly (with the parameters dialog), but when I try to use the controller (WHSPickListShippingController), I get an error saying "Pre-Processed RecId not found. Cannot process report. Indicates a development error."
The error is because in the class SrsReportProviderQueryBuilder (setArgs method), the map variable reportProviderParameters is empty. I have no idea why that is. The code in my Data provider runs okay. Here is my code for running the report :
WHSWorkId id = 'LAM-000052';
WHSPickListShippingController controller;
Args args;
WHSShipmentTable whsShipmentTable;
WHSWorkTable whsWorkTable;
clWHSPickListShippingContract contract; //My custom RDP Contract
whsShipmentTable = WHSShipmentTable::find(whsWorkTable.ShipmentId);
args = new Args(ssrsReportStr(WHSPickListShipping, Report));
args.record(whsShipmentTable);
args.parm(whsShipmentTable.LoadId);
contract = new clWHSPickListShippingContract();
controller = new WHSPickListShippingController();
controller.parmReportName(ssrsReportStr(WHSPickListShipping, Report));
controller.parmShowDialog(false);
controller.parmLoadFromSysLastValue(false);
controller.parmReportContract().parmRdpContract(contract);
controller.parmReportContract().parmRdpName(classStr(clWHSPickListShippingDP));
controller.parmReportContract().parmRdlContract().parmLanguageId(CompanyInfo::languageId());
controller.parmArgs(args);
controller.startOperation();
I don't know if I'm clear enough... But I've been looking for a fix for hours without success, so I thought I'd ask here. Is there a reason why this variable (which comes from the method parameter AifQueryBuilderArgs) would be empty?
I'm thinking your issue is with these lines (try removing):
controller.parmReportContract().parmRdpContract(contract);
controller.parmReportContract().parmRdpName(classStr(clWHSPickListShippingDP));
controller.parmReportContract().parmRdlContract().parmLanguageId(CompanyInfo::languageId());
The style I'd expect to see with your contract would be like this:
controller = new WHSPickListShippingController();
contract = controller.getDataContractObject();
contract.parmWhatever('ParametersHere');
controller.parmArgs(args);
And for the DataProvider clWHSPickListShippingDP, usually if a report is using a DataProvider, you don't manually set it, but the DP extends SRSReportDataProviderBase and has an attribute SRSReportParameterAttribute(...) decorating the class declaration in this style:
[SRSReportParameterAttribute(classstr(MyCustomContract))]
class MyCustomDP extends SRSReportDataProviderBase
{
// Vars
}
You are using controller.parmReportContract().parmRdpContract(contract); wrong, as this is more for run-time modifications. It's typically used for accessing the contract for preRunModifyContract overloads.
Build your CrossReference in a development environment then right click on \Classes\SrsReportDataContract\parmRdpContract and click Add-Ins>Cross-reference>Used By to see how that is generally used.
Ok, so now I feel very stupid for spending so much time on that error, when it's such a tiny thing...
The erronous line is that one :
controller.parmReportName(ssrsReportStr(WHSPickListShipping, Report));
Because WHSPickListShipping is the name of the AX report, but I renamed my custom report clWHSPickListShipping. What confused me was that my DataProvider class was executing as wanted.
So, I was attempting to do something like the following:
if(Meteor.isServer){
Meteor.methods({connect_to_api: function(vars){
// get data from remote API
return data;
}});
}
if(Meteor.isClient){
Template.myTpl.content = function(){
Meteor.call('connect_to_api', vars, function(err,data){
Session.set('placeholder', data);
});
return Session.get('placeholder');
};
}
This seemed to be working fine, but, of course, now breaks in 0.5.9 as the Session object has been removed from the server. How in the world do you now create a reactive Template that uses a server-only (stuff we don't want loading on the client) method call and get data back from that Method call. You can't put any Session references in the callback function because it doesn't exist on the server, and I don't know of any other reactive data sources available for this scenario.
I'm pretty new to Meteor, so I'm really trying to pin down best-practices stuff that has the best chance of being future-proof. Apparently the above implementation was not it.
EDIT: To clarify, this is not a problem of when I'm returning from the Template function. This is a problem of Session existing on the server. The above code will generate the following error message on the server:
Exception while invoking method 'connect_to_api' ReferenceError: Session is not defined
at Meteor.methods.connect_to_api (path/to/file.js:#:#)
at _.extend.protocol_handlers.method.exception ... etc etc
Setting the session in the callback seems to work fine, see this project I created on github: https://github.com/jtblin/meteor_session_test. In this example, I return data in a server method, and set it in the session in the callback.
There are 2 issues with your code:
1) Missing closing brace placement in Meteor.methods. The code should be:
Meteor.methods({
connect_to_api: function(vars) {
// get data from remote API
return data;
}
});
2) As explained above, you return the value in the session, before the callback is completed, i.e. before the callback method had the time to set the session variable. I guess this is why you don't see any data in the session variable yet.
I feel like an idiot (not the first time, not the last). Thanks to jtblin for showing me that Session.set does indeed work in the callback, I went back and scoured my Meteor.method function. Turns out there was one spot buried in the code where I was using Session.get which was what was throwing the error. Once I passed that value in from the client rather than trying to get it in the method itself, all was right with the world.
Oh, and you can indeed order things as above without issue.
I have an ajax-enabled WCF service that returns a set of JSON objects back to the browser. The service has a simple function that calls a business layer dll. This then returns the objects to the calling method.
Below is the service implementation (minus the Imports statements):
<ServiceContract(Namespace:="")> _
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)> _
<ServiceBehavior(IncludeExceptionDetailInFaults:=True, MaxItemsInObjectGraph:=5000)> _
Public Class NoteService
<OperationContract()> _
Public Function GetAllInsuredNotes(ByVal insuredID As Integer) As List(Of NoteExport)
Dim allNotes As New List(Of NoteExport)
Using nr As New NoteRepository()
allNotes = nr.GetInsuredNotesForExport(insuredID)
If allNotes Is Nothing Then
Throw New InvalidOperationException("The operation to retrieve notes caused an error.")
End If
End Using
Return allNotes.ToList()
End Function
The Javascript to call my service is as follows:
function exportToExcel(sender, eventArgs) {
var insuredID = $('input[id*=hdnInsuredID]').val();
NoteService.GetAllInsuredNotes(insuredID, OnNoteGetSuccess, OnNoteGetFailure, null);
}
function OnNoteGetSuccess(result) {
var insuredID = $('input[id*=hdnInsuredID]').val();
OutputExcel(insuredID, result);
return true;
}
function OnNoteGetFailure(result) {
alert('There was an error retrieving notes for export. Please contact the help desk for assistance.');
return false;
}
Basically my problem is this. Everything seems to work fine from the server side function standpoint. Every time I call the function client side, the server side code executes and the result is generated. However, the success callback function only gets called periodically. I can invoke the function several times and only have the callback executed once. The problem seems to grow worse the larger the result set returned.
I could understand if it was related to the MaxObjectsInGraph setting, but the problem isn't that the result never comes back if I have a large amount of data. It will come back sometimes every forth or fifth try, sometimes 2 tries in a row, sometimes 1 in ten tries. It seems very random.
I have spent at least 2 days racking my brain on this one and can't seem to discover the solution. Does anyone have any insight on this?
Ok, I figured out what was happening and thought I'd post it here in case anyone else experiences this kind of issue. Using fiddler was the tool that put me on the right track.
Basically, the link button I was using to make the call to the javascript function was calling a full page postback, not just calling the javascript function. So if the request was small enough, the response to the web service call came quickly and the web page ran the callback function with the new JSON data it received. As the data sets got larger, sometimes the response would come back in time for the page to process the results. However, sometimes the response wouldn't come back until the full page postback was complete and the reference to the callback function was lost. So it would get back the JSON data but wouldn't know what to do with it.
So I had the javascript function called by the link button always return false to cancel the post back and the problem was solved.
I only had one other issue to deal with and that was setting the MaxObjectsInGraph setting for the service to a high enough value to account for the JSON size coming back. The only thing I still find odd is that if this setting was not high enough, I would get a challenge response box asking for a login name for the first couple of attempts, then the service would just come back with an unknown status code.
In any case, I hope this post proves helpful to someone else.
I don't think we can help you figure it out either unless we have the JavaScript definition for
NoteService.GetAllInsuredNotes(insuredId, CallBack1, CallBack2, WhatIsThisParam)
