Forum: Radiant CMS Library and PaperClipped

Have been trying to get a gallery to work with Radiant.

I've tried the 'Galleries' extension - but could see no way to add
images from the asset list to the gallery.

Am also now looking at the Library extension and their fork of
Paperclipped - but after trying to run the rake development
db:migrate:extensions task - I'm now getting an error which says..

undefined method `is_taggable' for #<Class:0xb6d096f0>

..nor can I start the webserver.

Any ideas? Help?

I haven't tried, but you could run the task with "--trace"
rake db:migrate:extensions --trace

That will show you the stack trace and you can look for an error
coming from one of your extensions. It will tell you the line number
where the error occurs.

Also, you should be more specific here. You said that you are looking
at the Library extension "and their fork" of Paperclipped.
Pointing us to a specific repository would be helpful.

Are you sure you have the latest versions of these extensions? Or is
it possible that you have a version of Radiant that doesn't work with
a particular version of an extension? Often developers will tag
versions of their extensions on github.com for older versions of
Radiant.

Does the rake task work when your extensions are not in
vendor/extensions? (just move them out, try it, and move them back in)
Or is there some combination of extensions which causes the error? For
example, 1 extension might add features to another, but they are
loaded in the wrong order.
Extensions are loaded alphabetically (like plugins) but you can
specify their load order in config/environment.rb
If you have Library and Paperclipped, it's likely that Library is
loaded first and should not be.

Try setting "config.extensions = [:paperclipped, :library, :all]" and
adjust that as you need.

Ah sorry. That's my fault, I think. The library relies a variant of 
paperclip that I've been meaning for months to pull into the mainstream:

  https://github.com/spanner/paperclipped

However, in this case I think the problem is a missing 'taggable' 
extension:

  https://github.com/spanner/radiant-taggable-extension

I've updated all these extensions to take out the (deprecated) 
config.extension hooks but right now that means dependencies aren't 
properly caught and it's easy to miss something. Sorry about the hassle: 
everything will work when we standardise on gems but until then it's a 
bit in-between.

(You could try installing all this from gems, but there are 
complications there too because at the moment most of my extensions are 
waiting in beta versions for the configuration interface to make it into 
radiant. The gems currently available are the beta versions and not 
compatible with radiant 0.9.1, or indeed with radiant edge. You would 
need the 'preconfiguration' branch.)

As it happens I've just been updating an image gallery that uses exactly 
this combination:

So if there's anything I can do to help, do let me know.

best,

... or possibly just load order. Taggable and paperclipped have to load 
before the library extension does.
