In the web app I''m currently working on users can upload multiple images - and can also delete them later on. Is there a way to easily delete uploaded files in file-column? The deletion should affect the database and the file structure of course. I didn''t find any documentation for that... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Each image has an ID, parent_id and file_column field. Then, all you need to do is destroy any image record. I believe that takes care of the rest :) Cheers Mohit. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have the following model: class Entry < ActiveRecord::Base has_and_belongs_to_many :products file_column :image, :magick => { :versions => { "thumb" => "100x100", "medium" => "640x480" } } end So entry (which represents an image) has a file column in my understanding. My controller method to delete an entry looks like this: def delete @entry = Entry.find(params[:id]) @entry.products.clear Entry.delete(params[:id]) jump_back end This code does delete an entry and the relations to products but DOES NOT affect the files - i.e. the files (in my case several files per uploaded image) are remaining.... :-( -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

you can use AR''s before_destroy Callback to write a function that reads
the filenname/path from the column and deletes the files from the Disk
...
class Entry < ActiveRecord::Base
has_and_belongs_to_many :products
file_column :image, :magick => {
:versions => { "thumb" => "100x100",
"medium" => "640x480"
}
}
before_destroy :delete_img_file
protected
def delete_img_file
....some code to delete the image here ...
.... self.file_column should give you the filename/path (however thats
stored in there, dont know the plugin you used)....
end
end
