[Catalyst] Jemplate and AJAX woes...
hi, guys, I think Ajax is cool. With Jemplate, it sounds good that Javascript templating is possible. I tried to go chapter 7 of Jon Rockway's book. Looks good. For my system, I just needed something very basic. === 1) Load up a data input form 2) user selects loan type from a select box ( bearing values: '', 'personal' , 'commercial' ,'misc') 3) using the onChange method in javascript, I would then have an AJAX call (excuse my terminology please) to load another fragment into the existing form. This is because each loan type will have different attributes which I have to have as input. This fragment will be made out of various input types. 4) User fills up the remaining attribute values (after the specific form attribute values have been loaded). Looking at chapter 7(AddressBook Codes of Jon Rockway's book) === 1) two files, root/src/person_fragment.tt2 and root/src/search/address_results.tt2 would call address_fragment.tt2 2) address_fragment.tt2 would in turn invoke edit_address.tt2 (under the root/src/jemplate directory) with view_only set to true. For what I need to do (in my own little test project), I figured I get rid of the intermediate file, address_fragment.tt2 and just refer to edit_address.tt2 directly with view_only set to true. When i tried my changes out, well, 1) view_source keeps getting set all the time 2) the javascript does work when I click on Edit in the webpage. My questions are: === 1) roughly, what's wrong with cutting off the intermediate file, address_fragment.tt2 ? 2) I have been looking (googling) for Jemplates and got no luck really. Most of the AJAX tutes do not talk about Catalyst enough (what more of Jemplates)... Any good tutorials for Jemplates especially in terms of what I want to achieve (as described above)? 3) I used firebug for debugging but kept getting an error saying Jemplate.js has to be loaded first before anything. Is that normal?? I mean, I did everything there was to do as per the sample AddressBook Codes in chapter 7 of Jon Rockway's book.

hi guys (especially Jon), What's the user id and password for the AddressBook source codes from chapter 7 of the Catalyst Book (by Jon Rockway) ? thank you K.

I'm sorry I was unable to turn it around faster, but I hope it's useful for the future. The dispatcher change is trivial; most of the size is tests. These are modelled closely on existing tests, with the thought that consistency in the test suite is better than streamlining each case. -- Regards, Charles Bailey Lists: bailey _dot_ charles _at_ gmail _dot_ com Other: bailey _at_ newman _dot_ upenn _dot_ edu Catalyst_visit.patch Description: Binary data ___ 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/
Re: [Catalyst] Catalyst::*::REST and Javascript
Ya I agree that doc is a little wacky - I tend to craft my own urls
set the HTTP method appropriately - I stick the JSON-encoded data in a
'data' request parameter have my auto sub in my Root controller peel
it off of there put it in $c-data so it all looks the same after that.
like:
if (my $data = $c-stash-{raw_params}-{data}) {
$c-req-data(decode_json($data));
}

Wikipedia demonstrates REST like:
userResource = new Resource('http://example.com/users/001')
userResource.delete()
Whereas ExtJS seems to be of form:
userResource = new Resource('http://example.com/users?id=001')
The difference being that REST-proper encapsulates the id of the user in the
URI path, where as ExtJS includes it as a query parameter.
I like the former technique because it dovetails with Catalyst's
chaining paradigm nicely.
Looks like best practice for now is to craft URIs manually and feed them
into your YUI, jQuery, or
ExtJS AJAX routine of choice.

Re: [Catalyst] Cat + DBIC + DBD-Pg + mpm_worker -- Solution

DBD-Pg had some thread-safety work done years ago, and I meant to be fine.. However I'm seeing errors like this one: Couldn't render template undef error - DBD::Pg::db STORE failed: handle 2 is owned by thread 84e5bf0 not current thread 8fe48f8 (handles can't be shared between threads and your driver may need a CLONE method added) at /usr/lib/perl5/vendor_perl/5.8.8/DBIx/Class/Storage/DBI.pm line 723. I've checked, and I am running a recent version of DBD-Pg, that does indeed have the required CLONE function. (Ver 2.8.6) Are there any known issues with Cat+DBIC+DBD-Pg here? Or maybe I just have screwed something else up.. Following up on this after some more investigation last night.. I was previously using DBIx::Class::Schema::Loader. I swapped to a static DBIx::Class::Schema setup, and the problem vanished.. I had a google around for anyone else with this issue, and found a japanese site I can't understand which looks to be mentioning it too, including a fix. http://d.hatena.ne.jp/holidays-l/20070126/p1 I haven't tried the fix myself, being happy to use a static schema defn. (I prefer those anyway).. but thought I'd pass it on in case it can be applied to the mainline version.
