Display thumbnail image in list

[filagan]

I am trying to display a thumbnail image from a database in the
activescaffold list. Based on the documentation I have read so far I
am pretty sure I need to update the helper file but I am not sure of
the syntax for the image tag that I need to place there.

I am able to upload images and display images in a view

This is the code I placed in my helper file. This is the same code I
used to display the image in a view.

def photo_thumbnail_column (record)
img src="<%= url_for(:action => "get_thumbnail", :id => record.id)
%>"
end

Any help is much appreciated.

First, learn ruby, it will do you much goodness.

Second,

  def photo_thumbnail_column (record)
    image_tag(url_for(:action => "get_thumbnail", :id => record.id))
  end

have you tried using the file column integration?  If you declare an image with a version of "thumb", active scaffold automatically displays the thumb version.

Thanks. That did the trick.

I have not used the file column integration. I used the examples in
the Rails Cookbook to get me started.

Thanks again for your help.

selvan,

I got my examples of loading images to the database from the book
Rails Cookbook. You might be able to see excerpts of the book on the
net. The book covers everything you need including the other software
packages you need to install.

The book breaks down the process in 2 sections:
1. Loading the image from the file.
2. Displaying images from a database.

There is also a section on creating thumbnails from the uploaded
images.

done?
