Re: [SMW-devel] Set a SMW property programmatically in PHP?

2015-06-29 Thread Jason Ji 
Hi Nischay, Markus, and Yaron,

Thanks for your feedback. I replied to Yaron but neglected to reply-all to
the list: I did indeed ended up going with just manually embedding a
{{#set:}} in the page programmatically because it seemed overall safer and
easier to manage. Cindy Cicalese actually gave me the same warning about
having to re-set the data on page refreshes. :)

Re: [SMW-devel] Set a SMW property programmatically in PHP?

Hi Jason,

As both the SMW gurus said it can be dangerous but I think there is a way
to do it, I have a small implementation where I am already using it.

For this to work you need to have the information stored in a second source
as well to be able to update the information on page refreshes (I use a
separate db table). The way to update this property-value is to use
the updateDataBefore hook and update the value by fetching it from the
alternate source - of course there is some redundancy here but I guess you
already knew that by now.

Nischay Nahata

Indeed, one has to be very careful here. The key is to make the change 
at the correct place to ensure that the data is not lost on updates or 
refreshs, which may not always trigger all MediaWiki hooks that you 
would use during normal parsing. In particular, semantic data is always 
secondary data which comes (mostly) from the content of the page and (in 
rare cases) from other metadata of the page (as for SMW's Modification 
date property).

There are safe ways for setting properties from PHP, especially from 
within own parser functions. SMW's own #set parser function has examples 
on how to do this. Setting special properties like Modification date is 
more tricky.

What you are trying to do sounds dangerous though, since it seems that 
you are trying to set the value of something that is controlled by 
another extension. If this is the case, you should let the other 
extension control it and insert into the page text whatever is necessary 
to get the value that you want. You cannot change SMW data to be 
different from what is actually given in the page -- doing so will only 
cause a temporary inconsistency in the database that will be "fixed" as 
soon as the page is stored/refreshed again. SMW data does not have an 
independent existence or history. It must be regenerated reliably on 
every refresh of the page.

Hi Jason,

If you're talking about making a change to the semantic data of a page that
is not reflected in that page's wikitext, that sounds like a bad idea - the
new data would be removed as soon as the page was edited and saved again.
