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?

m sure of the path dear …

On top of that, if the current working directory is the root of the
app (which is usually is) then with a normal setup a browser won’t be
able to access that file, since its not in public.
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 typos probably won’t help - you spell the directory “aritcal” in
the check, and “artical” in the image tag.
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.

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.

In fact, “File.exist?” (without the ‘s’) is preferred according to the
API.
