Re: [Catalyst] KiokuDB, MongoDB and the NoSQL thing
Thanks for the link Darren. I will read and ponder. Also of interest, I seen that Search::GIN has had a new release. The post also mentions some docs explaining queries, but I have not found them yet. Active Search::GIN development would encourage KiokuDB usage I would think. Thanks for the posts regarding this topic. S.

I also learned something, such that what CouchDB and MongoDB specifically represent data with is JSON documents. So basically, what you pick out of today's choices depends on your priorities. ___ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
[Catalyst] KiokuDB, MongoDB and the NoSQL thing
I have a couple of production Catalyst/DBIx::Class sites on Debian stable, and then on my personal hobby site I use local::lib to try out new things. Recently I split out my users for this site into a separate model and I thought it a good exercise to learn and use KiokuDB. It was just a couple of simple objects, users roles, but I believe I have a better understanding of how a schema-less data model would work. All I do are lookups based on ID or indexed object values, but doing any type of ordering by dates or titles is a mystery. It seems that the Search::GIN is to provide this sort of functionality, but it is under-documented and has not had an update for awhile. I do not see many posts regarding uses of KiokuDB within Catalyst so I was curious about the opinion of the community in regards to its usage. Is it still to early within development? Also, I have been reading more about the increase in the NoSQL interest, with a particular interest in the MongoDB database (it seems to be similar in some respects to KiokuDB), but I do not find Perl people in the discussion as much as others (Ruby, PHP). Are there developers in the Catalyst community who lean toward NoSQL concepts over traditional RDMS's, or is best to view as a tool to use at times? How about MongoDB? Am I being suckered by another bandwagon?

[Catalyst] jQuery gotcha
Found a change in the latest jQuery (1.4.1) from the previous release I used
(1.3.2) that affected a Catalyst app of mine. Regarding form field
submissions, jQuery now submits multiple checkbox (or select) values with the
variable name followed by the array [] brackets (probably to appease PHP). I
had a problem with a previous working app and used firebug to look at my JSON
post and found the brackets.
What used to be:
tags 25
tags 18
tags 10
is now:
tags[] 25
tags[] 18
tags[] 10
Changing:
my $tags = $c-request-params-{tags};
to:
my $tags = $c-request-params-{'tags[]'};
corrected it (the quotes are needed). Hope this is helpful.
This was my first post, been reading forums for awhile and want to thank all of
you for the skill and knowledge you offer. I thank you for the forum posts,
blogs, calendars and books. I am not a trained programmer, but with your help
I have been able to build a few production Catalyst apps.
Thanks,
Scott K.
