I am still new to cache objectscript and am trying to figure out how I would go about removing the escape characters from my JSON below. When I call the $toJSON method it's adding the "\" character in the file path.

 

{"FileStatus":"P","Path":"\/somepath\/test\/test123\/filename.txt","InterchangeOID":"100458"}

I have a process that takes data from a CSV file (actually a record mapper object) and creates a nicely formatted JSON string I would love to send this along to a RESTful business operation.  However no matter what I try, I continually get <INVALID OREF> errors when trying to populate the object that extends Ens.Request to give it the JSON string.

I can add strings, other objects, you name it - but stuffing a JSON formatted variable/object into another object I want to send someplace is proving to be an impossibility.

Does anyone have an example of sending an Ens.Request or other object (not an HTTPRequest object - but some other custom object) containing a JSON string to an Operation where the operation ultimately pulls the JSON from the object that was sent to it, makes the REST POST call and sends the response back

Class ICT.Experiments.A Extends %Persistent
{
Property Name As %String;
Property Collection As list Of ICT.Experiments.B;
Property Collection2 As array Of ICT.Experiments.C;
}

Class ICT.Experiments.B Extends %Persistent
{
Property Name As %String;
}

Class ICT.Experiments.C Extends %Persistent
{
Property Name As %String;
}

I have the classes above and I can select columns from the array collection by using two joins as follows:

SELECT 
mainTable.ID, mainTable.Name, c.Name
FROM ICT_Experiments.A mainTable
LEFT JOIN ICT_Experiments.A_Collection2 arrayTable ON arrayTable.A = mainTable.%ID
LEFT JOIN ICT_Experiments.C c ON c.%ID = arrayTable.Collection

Terminal scripts can be used to run pre-designed commands on the terminal, like a batch file.  You can write anything that can be executed on terminal, like for loop, if else and so on,  inside Terminal scripts. In this article, I will show you how to call Terminal scripts, how to use parameters in Terminal scripts and how to avoid session disconnected when running Terminal scripts. If you have any information about how to use Terminal scripts or you have any feedback, please feel free to leave a comment

Dear team,

I am trying to experiment the Docker container in our development environment. I have successfully build an image and running the container. When I access the CSP portal home page ( http://<host-ip>:57772/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS), I am getting the following error:

Caché Server Pages Version 2017.1.1.111.0.17521
 
Server Availability Error
Server is currently unavailable

 

I logged in to the running container (docker exec -it <container-id> sh), issued the command, 'ccontrol list' where the state says 'warn'

Hello,

1)

I am trying to have a ZEN datacombo to display list of Namespaces column using a Class Query.

<dataCombo id="NamespaceId" queryClass="%SYS.NamespacequeryName="List" showQuery="true" />
This Classquery works fine in <tablepane> and also from terminal.

But the datacombo is not displaying the "Namespace" column but only the last two columns. I have tried property displaycolumn="1". But this is not working

Hi,

I have a global that holds users name and date of birth.

I would like to loop through them and check if the date of birth is more than 2 years based on todays date

so I have ^checker("under2", "Eric David", "02-05-2018")

I want to check the birthdate based on todays date to see if it is greater than 2. How do I access the birthdate in the global

Please can you advice

I tried :

set values = $order(^checker("under2"))
set td = $zdate($horolog, 3)
set ol = $p(^checker("under2"), ",", 3) // this does not work
while (values ' = "")
{
set difdays = $system.SQL.DateDiff("d", ol, td)
if difdays > 730
{    
set ^value("greater than 2")
}
}

InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time

Hi guys,

I'm curious about the development processes of those of you using Angular. 

The starting point is that, somewhere, there lives an Angular project full of (mostly) typescript files.  Eventually, those files need to be built, and the resulting built files served up to a browser.

Given that, let's say I want to go change one of the typescript files.  What are some clean ways to, during development, see that change reflected on the active webpage in the development environment.  For something like a .cls or .csp file, after you save and compile a changed file in Studio/Atelier, the IDE handles that entire build process for you, and from the developer's perspective it's just: compile, reload the webpage, and your changes are there

We at George James Software are pleased to announce that our acclaimed code debugger and editor Serenji is now available as a Visual Studio Code extension.

As well as supporting the latest InterSystems IRIS platform Serenji also works with earlier platforms, including versions lacking the server-side Atelier API support required by other VS Code extensions.

Serenji connects you directly to the code in your namespaces, resulting in an experience more familiar to existing Studio users. No need to export and import classes and routines.

We believe Serenji is the first extension to bring VS Code's powerful debugging features to ObjectScript developers.

What is the process in importing a role from one server to another server?

Let's say Server A is our main server that we maintain all of our resources / roles / users. We would like to get these over to Server B, Server C, Server D, etc.

It looks like when we import, there are tables and resources left in the destination servers that are not in the source server. It looks like whatever was in the destination server that was not part of the source server was not deleted from the import.

What is the proper way of exporting/importing a role so that this does not happen?

I'm using callin to get global values.

Here's a simple function to get string value from global and return it:

int GetGlobalStr(char *global, CACHE_EXSTRP result)
{
    int push = CACHEPUSHGLOBAL(strlen(global), global);

    // narg Number of subscript expressions pushed onto the argument stack.
    int narg = 0;

    // flag - Indicates behavior when global reference is undefined:
    // 0 — returns CACHE_ERUNDEF
    // 1 — returns CACHE_SUCCESS but the return value is an empty string.
    int flag = 1;

    int get = CACHEGLOBALGET(narg, flag);

    int pop = CACHEPOPEXSTR(result);

    return ZF_SUCCESS;
}

I get global value in result successfully. However I need to iterate over $lb. How can I do that?

Hello everyone,

I was first introduced to TDD almost 9 year ago, and I immediately fell in love with it. 
Nowadays it's become very popular but, unfortunately, I see that many companies don't use it. Moreover, many developers don't even know what it is exactly or how to use it, mainly beginners.

 

 

Overview

My goal with this article is to show how to use TDD with %UnitTest. I will show my workflow and explain how to use cosFaker, one of my first projects, which I created using Caché and recently uploaded to OpenExchange.

So buckle up and let's go.

I have problem with Cache installed on a colleague's Windows 10 laptop.  On the laptop, Cache was automatically configured to use IIS and this has worked fine with csp applications configured in the Management Portal.

Now this seems to have stopped working, and I can't work out why.  In IIS, the web application seems to be in the correct place.

I have manually mapped the various file extensions to CSPms, as per the documentation, but any attempt to navigate to a csp page produces an 500 error, which tells me precisely nothing about why this is happening.

For example,

http://localhost/csp/myapp/login.csp -> 500 error

 

 

 

I have re-installed Cache, with the repair option in the hope that this would reset any mappings or config settings to do with IIS, but it, too, has achieved nothing.

I am not a webserver guru, and this is the first time I have mucked around with IIS in literally years

Hi Team,

I am using Angular 7 with angular material for my client application that connects and obtains Access token from IRIS Authorization Server (OAUTH 2.0).  The problem that I am facing right now is regarding this access token being exposed to browser and stores in the local storage of the browser.

Hi guys!

Portrait of  Madame X, Gustave Caillebotte.

One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.

Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.

The trick is how you transfer an array to work with into a function. 

One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator. 

Below you can find a very simple example which illustrates the thing.

Hi,
We recover a large amount of data from an external database (SQLServer, about 1 million rows in JDBC).
However, we have treatment time issue.
This process takes more than 30 minutes whereas on a "classic" SQL Server Management Studio type request takes less than a minute.

While searching on the internet, I came across this article: http://makejavafaster.blogspot.com/2015/06/jdbc-fetch-size-performance.html
It explains how in Java, we can tweak the FetchSize parameter of the JDBC driver to optimize this kind of process.

Is there a way to access this JDBC parameter through the EnsLib.SQL.OutboundAdapter adapter?

If not, how do you deal with this kind of situation of large volumetry
