Hi, I have the following in a viewer Here, @lst = Homework.find(:all) is an array of homeworks. I checked this this is correct. Based on the error below, somehow, the url_for_file_colum does not like to act on the model element. I checked the source code to url_for_file_column, and the problem is with instance_variable_get().

Hmm, I''m using file_column and going by this tutorial, the files upload ok and I can see the fields updated in the database, but I am getting this error: "Trying to access file_column, but primary key got lost." Thanks in advance -- Posted via http://www.ruby-forum.com/.

1) installation is not as smooth as some other plug-ins. If you follow the instructions on http://www.kanthak.net/opensource/file_column/ it makes a directory called trunk instead of file_column. You have to manually rename it to file_column. I guess this is a minor annoyance but it gives me the feeling that things aren''t quite like other plugins. 2) I get this error: undefined

I am using the very helpful file_column extension in my app. The uploading portion works great - no problems. Where I am having an issue is displaying the images in my view. My code looks like this: <% for @record in @main_box_releases -%> <%= image_tag(url_for_file_column("record", "record_cover")) %> <% end -% @record is an instance of a class called

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

Hi all, I''m trying to use file_column to upload a picture but I''m getting the following error: "cannot convert nil into String" caused by the last line in FileColumnHelper::url_for_file_column(object_name, method) url << object.send("#{method}_relative_path") I don''t have any images uploaded for existing entries so does this not

To make file_column work I have to copy my local variable back to an instance variables like this: <% for product in @products @product = product %> <div class="catalogentry"> <%= image_tag url_for_file_column(''product'', ''image_url'') %></p> This is needed because file_column specifically looks for the instance

Hey, I''ve gotten file_column to upload a file, drop it in the dynamic directory, but I can''t display the image, the directories repeat themselves: My model: class Person < ActiveRecord::Base file_column :image_url In my view: <%= image_tag url_for_file_column(''person'', ''image_url'') %> HTML generated is this: <img

Hi, url_for_file_column @variable, ''name'', takes an instance variable. My question is, what if I don''t want to have to retrieve the instance variable every single time but I have the image id, along with its name with me. Could I contruct that object in a view and pass it to url_for_file_column: <% @picture = Picture.new %> @picture.id = ...

I also posted this on Rails Engines forum. Sorry for the double post. I am trying to configure file_column plugin so that it stores the images in a directory completely outside of RAILS_ROOT. I have no problems in storing the files by setting :root_path option. But I can''t get to display these images using ''url_for_file_column''. What I get instead of the image is

Hi, I downloaded FileColumn plugin and love the concept.

I''m trying to use file_column as a Rails plugin. Of course I read the doc (from Sebastian, this maillist) and little bit of source (as good as I, newbie, could understand it).. But I''m not able to implement it in my app.. I''m a totally newbie with less software development experience. I get the file_column_field in my view with simply invoking the helper... (:multipart

I use file_column and it works fine. I tried to change the store_dir to a the path I want my files to be stored and not the default. I stored some images fine. But when I try to reach my images it seems like file_column uses the model_name/attribute_name on the image and not the store_dir I used. How can I change this ? Thanks in advance -- Alexander Antonakakis

Hello, I upgraded my Rails app from 1.0 to 1.1.2. Basically everything worked on my development box. When I uploaded the changes (including the frozen 1.1.2 gems) to my webhost most things worked. However I had a problem with my application_helper.rb file. It wasn''t able to find the url_for_image_column method from the file_column plugin. Here''s the relevant code in

ok, here''s the deal. I''m having an issue using the file_column plugin on dreamhost. Everything works great on my local dev machine using webrick.

I though it might be a routing issue, so I tweaked the

Hi, I have recently moved my RoR app on the Heroku platform, and almost everything works fine apart from the videos. It works fine when my app runs in local but not on heroku.
