HI Steve,

I read the documentation and at one point it says to "require
[rails_file_column.rb] file from your 'config/environment.rb' (after
rails has been loaded) to integrate the file_column extension into

Did you put the plugin under /vendor/plugins/? Then you needn't any
requirements of this Plugin in your environment.

Im my view, I have something like

<%= image_tag url_for_file_column("product", "image"), {:class =>
"produktbild" } %>


i had the same problem when i first tried file_column. i figured it
out by reading through 'file_column_helper.rb' that is installed with
the plugin in the lib directory. here's what i found:

     object = instance_variable_get("@#{object.to_s}")

basically it gets a reference to the _INSTANCE_ variable that is being
referred to by the first string you pass to url_for_file_column.

this means that in your case you need a variable named "@product" that
holds a reference to the product you're trying to display the image
of. For instance, just try adding this to the top of your template and
see what happens.

    <% @product = product %>

a cleaner solution would probably be to set this instance variable
somewhere inside the controller that renders your template code.

hope that helps,

I encounter the same problem. What I did is change
     <%= image_tag url_for_file_column("product", "image_url") %>
     <%= image_tag url_for_file_column(product, "image_url") %>

and it works.

This is inspired by Jason S.'s post above, in 'file_column_helper.rb',
it will check if
the first parameter is a string or symbol, and tries to get the object
from it.

Since in your case, product is already an obj, you can just pass it in
