Nodecomment module up for grabs
by Jerad Bitner 28 Jan '09

28 Jan '09

Nodecomment module does just what it says, provides comments as nodes. I originally took over the project just to port it to D6 for my company at the time, but now I really have no use for it. I'm actually surprised people still find use for it in D6 because all of my reasons for using it have disappeared with Views2 and the comment support that other modules have upheld. There's still quite a few people using it but I have no time to dedicate to it (haven't for a while and I appologise for letting the issue queue get a bit out of hand). If anyone is interested in taking it up, please let me know off-list. Otherwise it'll find itself unmaintained again. Thanks, ~Jerad

how to display an extremely large document
by David Cohen 26 Jan '09

26 Jan '09

I'm building a site to support a very large outline of legal cases. There are thousands of nodes in the outline, each with a very small amount of text. The outline is about 5 or 6 levels deep. I've written some code to import the outline into the book module. So the book hierarchy reflects the outline and the node bodies contain these small chunks of text. I'd like to display the entire outline in a single page. This is not practical because of the overall size. Still I'd like the user to feel as if they are scrolling through the entire thing, not visiting thousands of different pages. My idea is to use AJAX to accomplish this. Imagine how google maps works (start somewhere but scroll to anywhere, use ajax to refresh the view after the scroll). I'd like the same thing for arbitrary HTML. In other words the browser starts with mostly placeholder divs and a small amount of content. As the user scrolls around, the placeholders get replaced with real content. And the real content which scrolls out of view gets cleaned up so the browser does not run out of memory. Has anyone encountered such a thing? Or would be interested in collaborating on it? Any reason why it would not work? Thanks, -Dave

taxonomy defaults based on URL arguments
by Ashraf Amayreh 25 Jan '09

25 Jan '09

Hello All, I was just thinking of creating a module that assigns default taxonomies inside a node add form based on arguments in the URL, for example: ?q=node/add/page/5/6/7/8 Where 5 and 7 would be vocabularies and 6 and 8 would be the respective desired values to be chosen in the vocab drop downs. The reason for this is that sometimes I want different taxonomies to be chosen by default depending on where I reach the node add form from. I searched for similar modules but they didn't quite implement this functionality as far as I could tell. This should be an extremely simple module to implement, I've done it so many times I felt it just warrants a simple module. So, are there any similar modules available? -- Ashraf Amayreh http://aamayreh.org

Field API! Review it, or forever hold your peace.
by Barry Jaspan 25 Jan '09

25 Jan '09

After a year of thought and (intermittent) work, the Drupal 7 Field API is very nearly a reality. The recent Fields in Core code sprint at Acquia was a great success and got us "over the hump" on the this project. Since then, the team has been working on finishing up the loose ends standing between us and the initial commit. The Field API is going to *replace* CCK's database functionality in D7 and beyond. If you think this might affect your Drupal-ish future, now would be a good time to review it and chime in with your opinion. If you choose not to, don't come complaining to me later. :-) You will probably find the Fields in Core Code Sprint Final Report a useful introduction: http://drupal.org/node/361042. I've set up a handy-dandy page describing the best way(s) to help: http://drupal.org/node/361849. To start you off in the right direction, though, here's a tip: the best two ways to help out RIGHT NOW are to review the Field API documentation (http://drupal.org/node/362764) and the current proposed Field API patch (http://drupal.org/node/361683) Note that the patch Field API patch is not in a ready-to-commit state yet but it is close and the key elements are all in place. You can also try out the CCK UI, but you'll have to get it directly from CVS contrib. Yes, this means that CCK will probably be ready on the day D7 is released. Yay for that. Thanks, Barry

libxml2 2.7.1 Breaks BlogAPI
by Jamie Holly 24 Jan '09

24 Jan '09

This is more of a heads up. I have had a couple of people contact me that they can't use blogapi on their sites. They are hosted with different companies. Then I had someone using Wordpress tell me the same thing. It turns out there is a bug in libxml2 2.7.1 that is stripping out the opening <. More info can be found on this Wordpress ticket: http://trac.wordpress.org/ticket/7771 And it appears that the CVS of libxml 2has been fixed: http://bugs.php.net/bug.php?id=45996 It appears that as hosting companies are updating then they are breaking xmlrpc (and any other module that might rely on libxml2). I figured I would throw out a warning in case we see an increase in support or tickets on this. -- Jamie Holly

Want drupal.org to show dev shapshot but not "released" for D7 version of module
by Syscrusher 23 Jan '09

23 Jan '09

Good evening! I've looked at the online docs but am still a little ambiguous. I have a module that I've ported to the latest snapshot of Drupal 7; my module's most recent previous version is for D6. It's "working" but not "finished" yet in the D7 version. I'd like to CVS tag it in such a way that drupal.org will show the D7 version as a nightly development snapshot, as I progress toward an official release. It looks to me as if what I want is "cvs tag -b DRUPAL-7--1" for the development branch, then make a drupal.org release for that tag. If I recall, that sticky-tag release node on d.o will track daily changes. But since we're talking about a sticky tag, I want to be sure. I know how to do the official releases for beta and production with non-sticky tags, but it's been a while since I did one of these. Thanks for any reminders someone might care to post.

High level request for hints...
by Steve 23 Jan '09

23 Jan '09

I've decided that I need to create a niche portal for a topic I've recently discovered I find interesting. My ideas are kind-of grand, but - potentially - flexible, too. The topic for my site is expected to be controversial, sometimes subjective - and usually complex... and the grand aim of the site is to establish a collaborative system in which a vast number of external sources can be referenced, summarised, peer reviewed and, in light of constructive criticism, improved. While I expect and accept that opinions will be posted, it is my aim to structure the site such that material backed by supporting evidence (such as a link to a corroborating document elsewhere on the web) 'floats' to be most prominent. I intend the material to my site to be more structured than that contributed to a Wiki... but to be organised more like a Wiki than a forum or a Slashdot clone. As I see it, the primary challenges I'm faced with are: * I need a bespoke ranking system for contributions - each of which needs an attribution, annotations of sources (maybe referencing one or more earlier contributions), peer-reviewed accuracy and relevance scores... where contributors accrue some sort of score relative to the credibility - which determines their influence on rankings. * I need a bespoke strategy to collate contributions so as to create as coherent a collection of data as possible... including both sides of a debate - if one arose. * While I've a few ideas about the broad structure of contributions now, I expect this to evolve during the lifetime of the site. It is essential that the implementation of the site remains flexible. * Each contribution, I think, can be captured on a "form" - including free-text, labels, dates, numbers - etc. - but contributions are likely to have associations... and I need to be able to display these. * I expect topical conversations - and I'd like keywords to link back to the emerging 'consensus' data - and for discussions to prompt enthusiasm and material to expand the more structured data. * Initially, I expect a very small volume of traffic and data - but I need to be able to cope if this were to grow exponentially... I can't justify building a site for 10,000 concurrent users at the outset (when 10 would probably be a coup) but I don't want to paint myself into a technical corner making it difficult to grow the site in future. In essence, I guess, I'm trying to build a self-organising expert-system based upon the contributions from site visitors - guiding and collating the material that emerges. I've fiddled with out-the-box Drupal 6, and I'm very impressed. I suspect that I may need to develop custom modules in order to achieve what I want - but, for obvious reasons, I hope to make maximum use of modules that already exist - where that reduces the burden of development. My main uncertainties at the moment include: * I'm unsure if I should pursue using the CCK - It seems to target something like what I'm trying to achieve using forms - but I'm uncertain if the DBMS schema that emerges will pose later problems... For example, it seems undesirable to have a 'node' for each of my CCK forms... and I'm concerned about scalability with the definition of views. Is it worth my while to persevere with the CCK, or am I best trying to use a custom module and define my own DBMS schema that way? * Should I start from scratch with my ambtious ideas about ranking contributors and their contributions, or is it a better idea to try to extend an existing modules (Karma, for example)? * Is it likely that I can integrate an emerging 'knowledge base' into a pre-existing forum module, or will I need to embrace/extend - or write my own? I'd be very interested to receive comments from those better versed in Drupal than I am... of all the frameworks I've researched - it shows the most hope... yet quite a lot of hurdles remain. I'd love to know if Drupal is already deployed to run a site with a structure similar to that I've described. I'd also appreciate hints as to suitable books... I've got "Pro Drupal Development" - the Apress one - but that seems to assume I know when I need to write a module, and how it fits into the wider scheme of existing modules. I'm wondering if there is something that covers topics such as making most effective use of the CCK and views... online tutorials seem somewhat ad-hock... if I'm going to use CCK then, I suspect, I'll need to think carefully about the DBMS schema to support later collation. Any pointers and/or hints gratefully received... Steve

Where do I get the form name? Thanks. - Sheryl
