Extension talk:Data Transfer

I have attempted to install the Data Transfer Extension, but when trying to go to the View XML page I get the following error: "Warning: Invalid argument supplied for foreach in C:\mediawiki\extensions\DataTransfer\specials\DT_ViewXML.php on line 189". This error is printed 7 times. The page looks fine below the errors. Is there an easy fix? Jascraig 12:17, 23 April 2008 (UTC)


 * Hi, thanks for the bug report. I think I know the problem - you have some pages that don't belong to any category, and Data Transfer wasn't expecting those. There's an easy fix, which I'll add to the next version of the extension. Yaron Koren 14:28, 23 April 2008 (UTC)


 * Yaron, Thanks, that fixed the problem. Now I'm having problems when I click Submit on the View XML page, instead of getting the XML I expect, I'm redirected back to my Wiki Main Page.  I am going to try and diagnose this locally, but if you have any ideas what could be causing this I would appreciate the information.  Thanks for the quick response.

About dt_xml_* messages
I'm a translater in translatewiki.net. dt_xml_* software messages such as dt_xml_namespace are used in xml outputs as names of elements or attributes. They are, however, translatable. When you export xml files in some wiki, they can't be imported in different language wikis because of lacking portability of xml outputs. Is this intentional? --fryed-peach 15:01, 16 April 2009 (UTC)


 * Well, Data Transfer was never meant to help with transferring pages from one wiki to another, since Special:Export and Special:Import already handle that; it's meant only for transferring data with non-wiki systems; so the tags can say anything. Yaron Koren 16:19, 16 April 2009 (UTC)


 * Thank you for your quick response. The current documentation is not clear to me around interwiki-portability. But now I understand its design. --fryed-peach 06:03, 17 April 2009 (UTC)

CSV example needed
I am unclear on how to properly format a CSV file to have it accepted by this extention. I am attempting to import a CSV file exported from Excel or Open Office.

Without the proper headers, the import generates this error: Error: the column 0 header, 'Revised: June 23, 2009', must be either 'Title', 'Free Text' or of the form 'template_name[field_name]'


 * As the documentation says, actually it's pretty easy. All you have to do is preparing the header, in one line. IE, with the following CSV:


 * George, 22, 1977, He is a good guy
 * Julian, 24, 1979, He is a bad guy


 * The proper header would be:


 * Title, People[date], People[year], Free Text


 * You also have to create the Template with the proper variable to take it. In this case, would be Template:People, and in there you should have something like this "He is year old, was born in ". And that's it.

#ask queries treated as templates
Hi... the XML output seems to treat {{#ask queries as templates, so I get:


 *  TypeUserDescription 

Is that the expected behaviour? - Borofkin 04:39, 14 January 2010 (UTC)

Call to a member function getNamespace
I have a CSV-file with 5400 rows of information created in Openoffice Calc and saved as CSV. Just titles and a short free text on each row. When I try to import the CSV I get an error saying:

Fatal error: Call to a member function getNamespace on a non-object in /home/christoffer/public_html/wiki/includes/JobQueue.php on line 277

This error seems to have something to do with non-UTF-8 encoded characters, but as far as I know I don't have any "special" character and my files are always saved with UTF-8 encoding. If I take some random rows from the file it works, but the whole file won't work. I have also tried to import a file with several non-UTF-8 characters like åäö, lots of quotation marks, commas and so on, and it also works. Is it the size of the file that is the problem (to big) or is it something else? --Squall Leonhart 22:37, 8 April 2010 (UTC)


 * Hi - if possible, could you try splitting this up into smaller files, and try importing those? At the very least, it'll help determine whether the problem is the file size, or some specific row(s); and maybe help isolate the offending rows, if any. Yaron Koren 00:47, 10 April 2010 (UTC)


 * I tried that now. I think I found the error. Some of the rows did contain characters like [], {} and ~ in the title column. When I removed them everything worked like a charm! --Squall Leonhart 13:16, 10 April 2010 (UTC)
