Hi, Sebastian
I downloaded FileColumn plugin and love the concept. But when I
tried the example listed on the plugin web site, I got the following
error:
NoMethodError in Entry#new
undefined method `file_column'' for Entry:Class
My environement is Red Hat linux 9.0 with mysql 4.1. I installed
file_column under vendor/plugins. If I run "ls", I get the following
directories:
file_column rails_file_column
I created a directory, " file_column" and copied files under
"trunk"
to file_column.
Please see my controller, models and new.rhtml attached.
Could anyone tell me why I got the error? It seems that rails can not
find "file_column" plugin.
Thanks in advance.

First, did you restart your webserver? Plugins are loaded once, during initialization, and not for every page load. Second, is there an init.rb file directly inside the vendor/plugins/file_column/ directory? If so, can you add some debug output such as "RAILS_DEFAULT_LOGGER.error ''inside init.rb'' " and see the output in your log files (this would confirm that init.rb is being seen by the initializer)? And you''re running Rails 1.0? Duane Johnson (canadaduane)

That''s a necessary piece of using file_column that isn''t well-documented. To clarify, for a file_column field called "image" you need 1) the plugin installed (which it looks like you''ve done, but double-check its permissions to make sure it''s readable to your webserver) 2) a varchar/string field in your table for each class attribute you want to use with file_column, in your case named "image" (which gets filled automagically with the filename) and 3) the declaration in the model (file_column :image) (which you''ve done right). -sk -- Posted via http://www.ruby-forum.com/.

Please delete both directories and make sure that everything from "trunk" lives in a "file_column" directory in "vendor/plugins", restart your web-server and try again. After deleting all old file_column directories, you should be able to install the files from "trunk" via the following command: ./script/plugin install \ http://opensvn.csie.org/rails_file_column/plugins/file_column/trunk Hope this helps Sebastian
