Getting number of records in data attached to document

[ashleyw42715064]

Hi

Could anyone tell me how to get the number of records in the data attached to a document?

I've been trying to write a script which needs this to work. I've been looking through the data model at DataMerge options and preferences but I can't seem to find anything that stores the data count.

Thanks!

doc.dataMergeProperties.dataMergePreferences.recordNumber;

[ashleyw42715064]

Hmm - that just reads 1, so it's just the record I'm on at the moment?

I tried going to the last record before running the script and it still came out as 1.

Do I need to do something else?

I'm using var doc = app.activeDocument;

Cheers

Hi Ashley,

see into other properties of dataMergePreferences as well:

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#DataMergePreference.html

Set recordSelection to RecordSelection.RANGE

And exploit property recordRange that returns a string.

var doc = app.documents[0];
doc.dataMergeProperties.dataMergePreferences.recordSelection = RecordSelection.RANGE;
var rangeString = doc.dataMergeProperties.dataMergePreferences.recordRange;
var lastNumberString = rangeString.split("-")[1];
var lastNumberAsInteger = parseInt( lastNumberString , 10 );

alert( lastNumberAsInteger );

Hi

That looks promising, but currently returns 500 instead of the actual 1500 records - that's because the last time I exported I only selected records 1-500.

I guess it should be possible to tweak this to get all the records all the time - I'll have a look!

Hi Brian,

property recordNumber is something else. From my German InDesign on Windows 10:

Hi Ashley,

then I suggest you set recordSelection first to RecordSelection.ALL_RECORDS.

Did not test this, but I hope that the range will adapt.

Hm…

If this does not help you may load the data source again.

Hi

Unfortunately it 'remembers' the previous range, so I'd need some way to change the range to specify the full range of records (and I guess if I could do that I would already have the total number of records!)

I'll tinker with it some more.

[Colin Flashman]

Yes. It's a bug. I usually create a variable for the total amount of records by doing a line-count of data within the text file being referenced.

csvFile.open('r'); 
var maxRange = csvFile.read().split(/\n/).length - 1;  //total length of actual records (not including the header)
csvFile.close();

Hi Colin

EDIT - Just tried it and I'm getting a 'csvFile is undefined' message. I can set up the var, but how do I tell it to look at the current data source?

Thanks

[brian_p_dts]

You need to define and open the CSV file first. 

var csvFile = File("path/to/file/thedata.csv");

For example, if the file is on your desktop and called data.csv, then you would do: 

var csvFile = "~/Desktop/data.csv";

csvFile.open('r');

Hello, old post but i'm in the same situation, i need to get the total of reccords. But i don't want to upload a news db file, i would like to get the one is in link. it's a txt can you help me ?

[Laubender]

Hi @Morgane33604108ep9w ,

see into this workaround:

Load the data source to a new document and get the range from there.

Hi Ashley,

it seems you cannot reply to this thread for unknown reason:

https://community.adobe.com/t5/indesign/cannot-reply-to-post/td-p/10947947

So I am trying a reply to see if something's wrong on the thread in the forum.

Just answered in the other thread, but I'll repeat it here.

Question was:
How can I know the data source file of a document template that is prepared for data merge?

It seems there is no property in the scripting DOM for this. I'd expect this perhaps with documentPreferences or dataMergePreferences. But no, it's missing.

The solution:

Export your document to IDML and look into Preferences.xml of the IDML container.

In the third line you should find the DataSourceFile attribute:

<DataMerge DataSourceFile="C:\folderName\fileName.txt" />
