Hi,

I’ve been trying to install the page\_attachments plugin from these  
instructions:  
[http://wiki.radiantcms.org/Installing\_Extension\_-\_Page\_Attachments](http://wiki.radiantcms.org/Installing_Extension_-_Page_Attachments)  
, but they don’t seem to work any more.

I’m using the Radiant Gem 0.6.4. The error I get is:

[shiny]:~/rails/site evansj$ rake production db:migrate  
(in /Users/evansj/rails/site)  
rake aborted!  
uninitialized constant PageAttachmentsExtension::Technoweenie

I tried ignoring the bit of the instructions that says  
“page\_attachments requires Radiant 0.6.2, so either freeze edge or use  
the 0.6.2 gem or later”, and did a rake radiant:freeze:edge anyway,  
but it still didn’t work.

I even tried creating a brand new blank radiant installation, with a  
brand new database. It still gave the same error when I tried to  
install the plugin.

So my first question is, what is the new procedure? 🙂

Secondly, would I be right in saying that most of the action is  
happening on the trunk, and I should just go for that? How stable is it?

Jon

I think what you want is:

$ rake production db:migrate:extensions

That doesn’t work either. 🙂

(See full trace by running task with --trace)

And I forgot to mention it last email, but obviously this problem  
stops the site from running as well:

You might want to look at how you installed the extension. Your  
page\_attachments directory should contain lib/technoweenie/ where the  
attachment\_fu code lives. I don’t really know the mechanism, but  
radiant/rails finds code in the lib directories automatically.

Anyway the technoweenie code is an svn:external wrt page\_attachments.  
Perhaps it’s just not installed?

I’d refer back to the wiki page for installing the extension, but I  
can’t seem to load it just now… Anyway I followed those instructions  
very recently and things worked properly.

One thing that might not be in those instructions is the need to load  
the shards extension prior to other extensions - I have a line in my  
config/environment.rb that reads:

config.extensions = [:shards, :textile\_filter, :markdown\_filter, :all]

Another difference between my setup and yours is that I am using Rev 631  
of radiant, not the 0.6.4 gem, and also not the trunk from svn. (I chose  
that rev because it contains a page caching fix I wanted.) I was worried  
about stability of the trunk, and prefer to use official releases where  
possible.

Also I’m using Rev 58 of page attachments.

Let me know if any of this helps…

Bill

OK, I think we’re getting somewhere now.

Sean?

On Feb 8th you edited the Page Attachments Installation page on the  
wiki ([http://wiki.radiantcms.org/Installing\_Extension\_-](http://wiki.radiantcms.org/Installing_Extension_-)  
\_Page\_Attachments) and changed the subversion URL to  
[http://dev.radiantcms.org/svn/radiant/trunk/extensions/page\_attachments](http://dev.radiantcms.org/svn/radiant/trunk/extensions/page_attachments)  
. But that version of page\_attachments doesn’t have the  
svn:externals property set in the lib dir so it doesn’t pull down the  
technoweenie code.

Now I’ve installed page\_attachments from the old svn url, radiant  
seems to run the migration properly.

I haven’t investigated the shards extension yet, but I’ll install it  
if it seems to need it. Same goes for using a different version of  
radiant itself.

Thanks again for your time

Jon,

Thanks. I intend to move the plugin to vendor/plugins anyway. I’ll do  
that ASAP.
