I have installed the Gallery Extension, but am not sure how to get started. I’ve read the README in rdoc, and have search through this lists’ archives, but have not found a simple example that shows how to create a new gallery so I can upload images. Will someone please help? Thanks, Phillip ---

If i remember correctly when you do rake radiant:extensions:gallery:install you should have two new default pages with a sample gallery. If you don’t you can create a new page and check the available tags. To upload files you should use the new tabs available in the admin console. 2007/10/30, Phillip K.

Giovanni / Andrea Thanks for the help. I had overlooked the Gallery tab in the admin interface. That was the part that befuddled me: how to create a new gallery and upload images. Got it now. Another question: As I’m working with galleries adding images and such, is there some easy way to get back to the Radiant admin home panel? Is Back all there is? Potential problem(s): I’m getting some Javascript errors when I go into Galleries off the Radiant admin panel. With one gallery defined, I get these two errors (reported in Firebug): - gallery\_tree has no properties gallery\_tree.createItem(1, null); gallery (line 46) - GalleryTree is not defined var gallery\_tree = new GalleryTree ({ gallery (line 3) When clicking on the one gallery to view it, I get this error: - GallerySortableList is not defined GallerySortableList.create(‘list’, … 1 (line 51) Clicking on the edit link of the one image in my gallery produces no result and this error: - GalleryItemPopup is not defined 1 (line 1) And finally, clicking on the “Switch to url mode” link produces this error - Gallery is not defined 1 (line 1) I’m using: Firefox 2.0.0.8 on Mac OS X 10.4 Radiant 0.6.2 (gem) Gallery 0.6.3 on Dreamhost (if it matters) Also, the /admin/gallery page is without style. Is that how it’s supposed to be? Using Firebug, I was looking for CSS that might be loading, and it does not appear to be loading any. Since this is a page off of the admin panel, I’m not sure if there’s anything that I need to do to make it work correctly. Peace, Phillip ---

After I sent the message before, I thought, “Oh, I should have included the Prototype version.” Heh heh. 1.5.0\_rc2. I suppose that is the version that is provided by Dreamhost’s rails install. Hmm… not sure where the rc\_2 came from. I just created a new rails app to check the default prototype, and it’s 1.5.0, which is coming from rails 1.2.3. Which version of Prototype do you suggest I use? Thanks, Phillip ---

I’ve just installed radiant from gem 0.6.3, and the gallery extension 0.6.3 (the same version 😛 ) and all work fine…can you try with these versions? ---

Thanks for testing, Andrea. Unfortunately, I’ve not been able to upgrade to Radiant 0.6.3 on DreamHost. I’ve been trying off and on all day and the process gets killed every time. Might you have some other suggestion that I can try? I did give Prototype 1.5.1.1 a shot, but that resulted in 14000+ Javascript errors (which I believe is due to a mismatch between Prototype and Scriptaculous…I’ve encountered that before). Peace, Phillip ---

Yo Philip, I have an instance of radiant 0.6.2 here: [http://gor.bigchieflabs.com/demo](http://gor.bigchieflabs.com/demo) with prototype 1.5.0\_rc2…and all works…it’s very strange…I’ll try again tomorrow 🙂 ---

Is your site online right now? maybe the problem is related to the way paths are mapped… are you using radiant in a subdirectory? ---

Thanks Andrea. I’d like to say again something I said earlier, but using different words 🙂 When I enter the Radiant admin panel and click on the Galleries tab, the resulting page (which I think is your list.rhtml) is not rendering in Radiant’s application.rhtml layout. No stylesheets or javascripts are being loaded. I have sort of managed to get Radiant 0.6.3 installed. It’s updated anyway, but now my Radiant project isn’t working and the upgrade instructions don’t work for me. Thanks for all your help. Phillip ---

I am working on an image extension, which stores the images in the database, then resizes them on retrieval. To make this at all usable, I of course need to be able to cache the images. I had hoped to use the Radiant system to do this, but so far have been unable to make this work. I am basing the controller on the Radiant site\_controller and have been able to write the image to the cache folder without problem. The problems start when retrieving the image: first it does not recognize that an image has been cached and when I force it, then retrieving the image results in a blank page. Two questions: should I even bother with the Radiant system? Does it bring me an advantage or should I just use the standard rails caching. Second Question: what am I doing wrong? Can this system even cache images? Here is the image\_controller, anything totally stupid and obvious? [http://pastie.caboo.se/113246](http://pastie.caboo.se/113246) Thanks for any help. Keith B. ---

No, radiant is not in a subdir. It’s a gem. Can you elaborate a little about your mapping thought? I’ve been working with rails for only about 6 months, and I have not yet ventured into anything other than the most basic route mapping. Thanks, Phillip ---

You’re doing nothing wrong, in fact, you’re reproducing my shards\_attachment extension (which you shouldn’t use because I find parts of it distasteful and plan on rewriting it with unit tests and a decent interface for transformation… eventually) [http://soxbox.no-ip.org/radiant/svn/extensions/shard\_attachments/](http://soxbox.no-ip.org/radiant/svn/extensions/shard_attachments/) and probably more specifically: [http://soxbox.no-ip.org/radiant/svn/extensions/shard\_attachments/lib/part\_attachments/site\_controller\_extension.rb](http://soxbox.no-ip.org/radiant/svn/extensions/shard_attachments/lib/part_attachments/site_controller_extension.rb) There’s nothing that jumps out at me from your code as being wrong, but I’ve been using the same technique that you’re attempting for well over a year now, and it works a treat for me.

Dan, thanks for the example, I got it working. The url I was checking was incorrect, now that the cache method checks the correct url, it works just fine. Keith ---
