Calling web API from report

February 17, 2016, 9:21 am
$

Hello, hoping someone can answer a question as I'm very new to javascript and even programming in general. Our company has a web api that is used in other reporting tools to figure out the number of business days between two dates. I am able to call this in a Pentaho Dashboard already, but I would like to use it in a report also but don't know how. Here's the function that is used in our Pentaho dashboard, normally in the post-fetch of some query object to manipulate the data...

function getBusinessDays(startDate, endDate) {

var startDateNew = startDate.replace(/\//g, ".");
var endDateNew = endDate.replace(/\//g, ".");
var result = 0;
var url = 'http://mycompany/api/totbusinessdays/' + startDateNew + '/' + endDateNew;
$.getJSON(url, function(data){
result = data[0].BusinessDays;
});
return result;
}

But now I would like to use this functionality in a Pentaho Report, but I have no idea how to do any type of custom coding in Report Designer. Any suggestions or advise? Is this even possible in Report Designer? Ideally users would enter the start and end dates for each report before running, and the business days would be used in a parameter-like fashion in various expressions. I hope this can be done as I would very much like to use Pentaho for both dashboards and reports, I'm just not very knowledgeable about how to get this working in a report though. Any help would be greatly appreciated!

Hi, all.

I'm having problems with Set variables step. It is writing the values asigned in the log, and one of them is a password. I've try disabling logging in the transformation, but it is writing in the log anyway.

Does anyone know how to avoid that this step writes in the log?

Thank you in advance.

Rest Client truncating result

I have developed the following transformation:

wholeProcess.jpg

It almost works perfectly, however the result of the Rest Client is being truncated.
I created a simple Web Service to test this process and it returns the following JSON:

browserOut.png

When the previewed the Rest Client shows that field9 and the closing bracket are missing.

I output the result of the Web Service to a field called result.

restClientEdit.jpg

Is there a size limit to the output field? Is there a way to change the size of the field? Is there a better way of handling this?

Copy table(s) wizard does not allow to specify a schema?

Greetings all,

I am new to Kettle, I am exploring its use to do an Oracle to Postgres migration. I was able to copy a large table using a dummy schema and database on the target and source. But when I went to run a more real world test using the real application schemas, I discovered on the target (Postgres) side I'm not able to specifiy the correct schema and it looks for everything in public.

So my question is can we provide a target schema in a database somehow? One the source (Oracle) side, I have no problems.

Thanks.

New Ctools Releases - 16.01.22: Commencing Countdown, Engines on

Commencing countdown, engines on

Can you imagine something more absolutely and completely boring than a product changelog? An endless list of jira numbers, bug fixes, features and improvements whose sight alone makes the brain cringe?


Well, think again. This is Pentaho.
Even when the task at hand seems completely disheartening, with some sleight of hand, irreverence and imagination it's possible to bring color into the otherwise black and white scene of technology.




This was exactly what the Pentaho UX team did with the latest Ctools release changelog. If you take a look, you'll find this:




Now, this is undoubtedly a really cool site. But as we all know, the devil is in the details. And there's a tiny, tiny detail here that, at least for me, turned an informative navigation into an emotional experience.
While browsing the site, make sure to pay attention to the fact that there's a star waiting in the sky. And I'm willing to bet that at least some of you won't be able to hold back a genuine smile when clicking there.




So simple. So easy. So impactful. Hats off to them.
Now, what if the rest of us could bring some of this type of magic to what we do on a daily basis? Can you just imagine what we could all achieve regardless of the task at hand? Yes?


So let's do it.

Hi All,I

am working on a sunburst chart.
I need to know is there any options to set the background color of the values font. because some slices in the chart has black font & some are having white.
I want it to be uniform & able to set/change by developer.
I have tried extension points, valuesFont, valuesLabelFillStyle but nothing worked out.

Also is the any property in sunburst chart to link the labels outside of the slice? if so, how to do it? I have tried 'valuesLabelStyle' from pie chart but it is not working.

Thanks,

MetaData Injection and variables

February 18, 2016, 1:07 am
$

0
We regularly use the metaData Injection step in our ETL programming and i have some issues when we use variables as database connections.
It seems that the variables are kept in-memory somewhere when using the injection step.

I thought that when using the injection step, a temporary file is made and that is executed. Is it possible that that temp file is not deleted when the job is run again from spoon?

The problem was that the database (sqlite file) wasn't found. When testing the variable is getting injected but not used in the connection part.
To resolve this, i need to restart spoon.

Can anyone explain this behaviour?

Hi there,

has anybody made experiences using the Dimension lookup/update step with columnar databases like Exasol, Vertica ...
I wonder whether the databases like ( in respect of performance ) the row-wise handling or not.

In case they don't - is there any known attempt to implement generic jobs using batch-sql to do that sort of stuff ?

Run multiple versions of PDI and Java

We are wanting to migrate our current environment PDI 4.4.x to 6.x. We want to keep our current environment 4.4 running while we port each Job/transformation to 6.x. The 4.4.x is using an older version of Java and the 6.x will be using the latest version of java. This will be happening on the same box (Windows).

The only gotcha that we can see is there are two hidden folders in windows called .Pentaho and .Kitchen that hold specifics to pentaho.

If anyone has done this or has recommendations on how to implement this it would be greatly appreciated.

Help on Line Chart no data available only first time

Hi everyone!! I need your help, I'm working on biserver 5.4 and CDE up to date.
My dashboard has a table which datasource gets changed depending on which button the user clicks, taking int 2 params. That's working nice.
From that table, i've defined a clickAction which alters a chart definition, taking the same 2 int params plus the table series selected.
The thing is, the first time a user clicks on that table i've got a "no data available" message, only the fist time, then if the table is show again and clicks on any series, the chart is displayed nice.

What am i doing wrong??

Table clickAction:
function g(a){
Dashboards.fireChange('PARAM1',a.series);
}
The chart listens to PARAM1
chart preExecution partial:
function a() {
render_Depto_x_Periodo.chartDefinition.title = Dashboards.getParameterValue("PARAM1");
render_Depto_x_Periodo.chartDefinition.titleFont = "bold 16px Verdana, Geneva, sans-serif";
render_Depto_x_Periodo.chartDefinition.path = "/public/Indicadores.cda";

render_Depto_x_Periodo.chartDefinition.orthoAxisTitle='Porcentaje';
render_Depto_x_Periodo.chartDefinition.orthoAxisFixedMax=100;

render_Depto_x_Periodo.chartDefinition.ortho2AxisPosition='right';
render_Depto_x_Periodo.chartDefinition.plot2=true;
render_Depto_x_Periodo.chartDefinition.plot2OrthoAxis=2;

switch (Dashboards.getParameterValue("Indicador")){
case "C" :
render_Depto_x_Periodo.chartDefinition.dataAccessId = "dsKettle_C";
render_Depto_x_Periodo.chartDefinition.plot2Series=['TOTAL'];
render_Depto_x_Periodo.chartDefinition.dimensions= {
series: {
formatter: function(v) {
switch(v) {
// a few case for names display

I'm at a loss here, the exact same setup works fine on other servers, so I believe it may be an environment issue. Does anybody have any ideas for me to try?
