Hi All

It's been 6 weeks since my original article 
- - - - -but I have been busy on this project 

I have been looking at/thinking about a replacement for ZEN for around 12 months but only really started in depth 4 months ago.
Also been in IT for long enough that I can "get a feel" for a product/technology and make decisions accordingly without going into great detail. 
Any new technology has a learning curve and I don't want to waste time and effort on something that won't fly. 
And, as always, I am looking to minimise the learning curve as I want to concentrate on delivering business benefit. 

Hi Community

I have created a simple package that allows the use of Cache with the Laravel Framework.

From my initial testing everything seems to be operating smoothly but I would like to appeal to the PHP users in the community to help me improve this package.

For those of you out there who have time and would be interested in this, please visit the repo at https://github.com/jeandormehl/laracache

Thanks in advance

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

The following class contains 1 class method "test" that creates a Zen Application and Page:

Working on a proyect with :

Cache Object Script, Jquery and Bootstrap :

I have a big problem to do pagination with parameter, to query filter and registry limitation, but i find a solution using session and global:

This code snippet provides a ZEN page that downloads a stream from its database directly:

/// We assume that you have stored your data within this schema:
/// MyApp.Model.Storage: Filename,FileSize,Content,ContentType
Class zen.downloadStream Extends (%ZEN.Component.page,%CSP.StreamServer)
{
 
    /// Wrapper to get the id of the download, we assume that the id is passed to this zen page
    /// as a URI parameter, i.e.: MyApp.Downloads.cls?OID=1234
    ClassMethod GetId()
    {
        Quit $Get(%request.Data("OID",1))
    }
     
    /// Set the appropriate header for the file.
    ClassMethod OnPreHTTP() As %Boolean
    {
        Set tId = ..GetId()
     
        If ##Class(MyApp.Model.Storage).%ExistsId(tId) {
            Set tStream = ##Class(MyApp.Model.Storage).%OpenId(tId)
            // You could "guess" the content type by its file extension
            // or you can store it (before) in the database separately (like in this example).
            // Set Extension = $Piece(tStream.Filename,".",$Length(tStream.Filename,"."))
            // Set ContentType = ..FileClassify(Extension)
     
            Set %response.ContentType = tStream.ContentType
            Do %response.SetHeader("content-disposition","attachment; filename="_tStream.Filename)
            Do %response.SetHeader("Content-Length",tStream.FileSize)
        }
        Else {
            Set %response.Status="404 File Not Found"
            Quit 0
        }
        Quit $$$OK
    }
     
    ClassMethod OnPage() As %Status
    {
        Set Download = ##Class(MyApp.Model.Storage).%OpenId(..GetId())
        Do Download.Content.OutputToDevice()
        Quit $$$OK
    }
 
}

404 Not Found

{
"error": {
 "errors": [
  {
   "domain": "global",
   "reason": "notFound",
   "message": "Not Found"
  }
 ],
 "code": 404,
 "message": "Not Found"
 }
}

I want to do something like the above sample from a Google Storage JSON API. I have a call to Write obj.%ToJSON() followed by return ..ReportHttpStatusCode(..#HTTP404NOTFOUND) however the HTTP Status code is always 200.  If I remove the Write obj.%ToJSON() statement it returns a 404 status with no body. How do I return both?

I faced with the issue when WebSocket connection just fails without any errors if I send data with size 384 bytes and more (In binary mode the same). As I know by standard WebSockets frame does not have such limitation. Is there any way how to decrease it? This limitation too small, it is too difficult to fit this size and needs to send data much more often than I expected. Tested with Caché 2016.2, 2017.2 and IRIS 2018.1.

Good afternoon everyone,

I hope you are well,

I am currently working on the below opportunity and if anyone here would like to hear more details please feel free to contact me on 01908 886 030 or teo.rusu@identifiglobal.com

Hi All

I am an avid user of ZEN for over 10 years now and it works for me.
But it seems that Intersystems are no longer actively developing it (or ZEN Mojo), the only published reference to this  is here

Does developing a RESTful API in Caché remove the requirement to use the InterSystems.Data.CacheClient.dll and generate proxy classes using the Caché Object Binding Wizard for .NET web development? If anyone has links to sample applications using .NET with Caché and REST Services, I would be grateful if you could share them.

Hi guys,

I am using the %Net.HttpRequest method to get data from a server.

The server will continuously send data. Is there any way that i can able to read the HttpResponse data line by line so that if at a particular line i may terminate the request.

Please advice.

Thanks,

Arya

Hi All,

Does anybody has experience with Angular application and have implemented some solution in order to track and record pageviews?

We are interested in to know how to capture those pageviews information and call a Caché REST Api in order to store those data.

Thanks.
