I’ve updated my alias behavior to an page type extension and added tests. [http://silverinsanity.com/~benji/radiant/alias\_page-0.1.tar.gz](http://silverinsanity.com/~benji/radiant/alias_page-0.1.tar.gz) Questions, comments, and bug reports welcome. ~~ Brian ---

Hi Brian, What does the extension do exactly? Is there a bit of documentation? Regards, Erik.

Mark a page as an Alias Page, and add a source part. The source part is a path (not a URL) to another page in the system. Whenever the system asks for that page, it will return the source page. It will, however, search for it’s own children before the source’s. I plan to use this in conjunction with the virtual domain extension to have the same page under multiple domains. There is something resembling documentation in the code. ~~ Brian ---

Thanks Brian, That is unfortunate for me, I was looking for the reverse ☹ I hoped to find an extension that would re-direct to another page so I can maintain some URLs when I migrate to Radiant. Regards, Erik. ---

I’ve taken the approach of having a separate table mapping urls to page numbers and a file not found behaviour that performs redirects for old mappings (I also trawl through my server logs for 404s and correct any repeated spelling mistakes / truncations) - I’ve left it as a separate table that I maintain by hand so as not to confuse the page tree.

> That rocks. It would be great if you could make that a separate > extension with an interface to manage the redirect table. (Hint, > hint. ~\_^) Well, you’re free to take my code and clean it up (Hint, hint). The extension works great for regular pages but not so well for pages that can be referenced by multiple urls - ie, my gigs page is a single page that filters gigs based on the last part of the url - since my mapping is from url to page id and not url to url, that means I can’t redirect to those individual state filters. My comics page (AlphabetPage) is a similar beast. The reasoning behind this is that these old urls are likely to be referenced well into the future and I wanted it to be robust in the face of reparenting. I had a brief discussion a week or two ago about having a page url table that would map urls to pages for fast lookup and would also remain persistant so that if a page moves, there would still be a reference in the lookup table for that page so that it’s old url would also work. There’s a few problems with that approach, but it’s something that I’d like to try fleshing out to see if those problems are surmountable - I think that might be the way to go for providing page aliases.

Something about using IN bothers me a little, but I don’t think that feeling is justified (just a voice in the back of my mind saying “OMG!! what if you have like a bajillion different not found page types? That would suck” - I try not to listen to that voice though, he’s a bit of a doofus). Dan. ---

Might be better to have a registration method instead. class MyNotFoundPage \< Page not\_found\_class end That way the class array is assembled once, and the IN itself should be relatively quick (It’s a common DB operation). ~~ Brian ---

I know that there’s definitely a method on ActiveRecord::Base that keeps track of subclasses as their created - maybe it’s called something else - descendants maybe? - I can’t remember, but I’m pretty sure it exists.

I found the code that I remembered seeing - it was for tracking of subclasses by observers - where for some reason the list of subclasses is stored by each observer rather than by the observee.

Hello, I’m working on a Gallery extension…i created a gallery section in the admin panel (to manage files uploading / sorting etc) and a Gallery page type… when I create a gallery page i use shomething like this in the body part: \ - - ![]()" /\> if request\_uri is shomething like: /gallery\_page/ …it displays the galleries list… if it is: /gallery\_page/:id it displays the list of images/files in the selected gallery. I use this code because the body part is displayed by default… It could be better to split the code in different part…in the body part the code for the galleries and in a ‘gallery’ part the code used to display the list of files…and then render the right part if in the request\_uri there is the id or not… is it possible using some hack in my gallery model? or i can use another method? thx * * * Andrea F.

I am, great job of moving it to git. Very easy to get and install. I thought maybe there are some requirements like imagemagick and rmagick. I don’t have those gems installed so if they’re needed it makes sense, I guess. If they are needed seems like it would be a good idea to add that to the readme file. ---

Oh, mini\_magick might be better. I’m hosting on Joyent and they don’t have rmagick. They don’t have mini\_magick either but I might be able to freeze that one in. What changes do I need to make to have it work with mini\_magick? ---

Are you sure Joyent doesn’t have RMagick? I have a couple of Radiant sites there using both my own extensions and Sean’s page\_attachments with RMagick. Mini\_magick does not work there, even if you freeze the gem. I just discovered Paperclip, [http://www.thoughtbot.com/projects/paperclip](http://www.thoughtbot.com/projects/paperclip) . It resizes images without RMagick or Mini\_magick, just using the image\_magick library itself. I have a prototype extension based on it, though it is not a full fledged gallery like Andrea’s.
