maybe this is due to your relative path. are you sure the file is
where you think it is? are you sure the current working directory is
what you think it is?
try File::exists?("#{RAILS_ROOT}/path/to/my/file")
another thing: since you obviously left out some code and replaced it
with "..." we can''t be sure your code is correct. are you?

If that''s not the case then you''re going to have to explain in what way things don''t work. Does it work if you try from a console? is @content what you think it is?

The method I''ve seen for checking files is "File.exists?..." not "File::exists?" (not sure if your way would work anyway) And as others have said, even if the file does exist, the image tag won''t see it because it''s not in the public path. But let''s come back to the problem you''re trying to solve: how are you attaching files to your content object? Maybe using a plugin like paperclip would save you a lot of the hassle. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I experienced the same problems in a Ruby and Rails project. But when I used File.exist? instead of File.exists? it did work properly. Seems there is a problem with that or it works different.
