Dear all
I am new to rails.
In view, I place the following code, but cannot show the picture in the
webpage
<%= image_tag("green.JPG") %>
However, I can access the picture in this url
http://localhost:3000/images/green.JPG
The HTML source code generated
<img alt="Green" src="/images/green.JPG.?1228211220"
/>
I cannot identify the problem. Please help
Thank you very much
Valentino

Do you have the image in the image folder or any other folder?
Also check the extension of that image name(Whether
uppercase("green.JPG") or lowercase("green.jpg")). Give
correctly.

Next, always use lower case file extensions - jpg.

The big question is why image_tag adds that extra dot. It shouldn''t. Have you looked at the source code for image_tag? You didn''t accidentally override it or anything like that? mcv. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hello all
I think I identified the problem now
In asset_tag_help.rb, the problem might cause from *****(see below
code). I am using Rails 2.1.2, I will try the latest version to see the
problem has been fixed. Thanks all
def image_path(source)
compute_public_path(source, ''images'')
end
def compute_public_path(source, dir, ext = nil, include_host =
true)
has_request = @controller.respond_to?(:request)
cache_key if has_request
[ @controller.request.protocol,
ActionController::Base.asset_host.to_s,
@controller.request.relative_url_root,
dir, source, ext, include_host ].join
else
[ ActionController::Base.asset_host.to_s,
dir, source, ext, include_host ].join
end
ActionView::Base.computed_public_paths[cache_key] || begin
***** source += ".#{ext}" if ext &&
File.extname(source).blank? || File.exist?(File.join(ASSETS_DIR, dir,
"#{source}.#{ext}"))
if source =~ %r{^[-a-z]+://}
source
else
source = "/#{dir}/#{source}" unless source[0] == ?/
if has_request
unless source =~
%r{^#{@controller.request.relative_url_root}/}
source =
"#{@controller.request.relative_url_root}#{source}"
end
end
rewrite_asset_path(source)
end
end

In this case, I think ext is nil, so this should be causing the problem. But if something is really mysterious (and in Rails it often is), then I just add lots of debug statements and see what really happens. puts all the names of methods that are called, and all relevant variables (or just use the debugger, of course!), and see where the dot is added. You may have found a bug in Rails.> if source =~ %r{^[-a-z]+://} > source > else > source = "/#{dir}/#{source}" unless source[0] == ?/ > if has_request > unless source =~ > %r{^#{@controller.request.relative_url_root}/} > source > "#{@controller.request.relative_url_root}#{source}" > end > end > > rewrite_asset_path(source) > end > endAll this code is also capable of changing source. I''ve got no idea what it does, but if you just puts the value of source after each one, you''ll see where the dot gets added. That''s the only advice I can give you. Other than that, I''m stumped. mcv. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
