Render partials in folders
Right now I have partials in a view folder corresponding with my controller.
ie: controller: example, view: example/_partial.rhtml
and I call it with render :partial => ''partial''
How do I add the partial to another folder and call it?
ie: controller: example, view: example/new_folder/_partial.rhtml
render :partial => ''new_folder/partial'' # does NOT work

Iframe upload indicator
I''m using the iframe trick to upload files with form_tag and a target
pointing to the iframe. All is working, but I would like to display an
indicator of the upload. All I want to do is show a hidden animated gif via
Element.show. With form_remote_tag, i could use the :loading and :complete
callbacks to do an Element.show and Element.hide. How do I achieve a similar
effect with form_tag?

:revert => false for Droppables
Right now I am using page.remove and page.insert for some complex nested
moves in RJS. I have my draggables set to revert, but they also revert when
they hit a droppable.
Meaning, the draggable will start reverting for part of a second before the
page.remove kicks in. Is there a way to specify :revert => false for the
drop_receiving_element, or something else to that affect?

Upload to DB hang mentioned in wiki
I''m uploading files to a mysql database, using a mediumblob size.
Following the wiki here:
http://wiki.rubyonrails.org/rails/pages/HowtoUploadFiles ,
I got past the first mysql 500kb limitation with the max_allowed_packet = xM
trick, setting it to 1000M.
However, as the person at the very bottom of the wiki notes, I too cannot
upload more than around 10mb.

send_file but not send_data?
So this is the original code I used, and it worked

"sprite-not-found.png", :type => "image/png", :disposition => "inline"}
Now I switched it to this (going to be adding imageMagick)

send_file VS. send_data (performance)
Does anybody know if there is a big performance/time cost difference
between these two methods of serving a file:
------------------------------- #1
-----------------------------------------
send_file "test.png", :type => ''image/png'', :disposition => ''inline''

trouble streaming images with send_data
Hi
I''m doing some server-side graphics with Java2D and I''m trying to
stream the resulting image to the browser using send_data. When I try
to view the image that I streamed, the browser just shows the URL in
the window as a very small image (about .4 kb) when I am using jpeg
format. For png, it tells me that the image has errors and can''t load
it.

send_data => invalid byte sequence in US-ASCII
I''m trying to display a generated .png plot via send_data(), but it
results in a server error "invalid byte sequence in US-ASCII" error.
I''m pretty sure this means that I need to specify the encoding
somewhere, but I haven''t been able to figure out where or how to do so.
Some particulars:
I''m running gnuplot through a pipe to generate a plot in .png

Hi,
for those with experience of Gruff module: suppose I want to send

Can't download files with send_data or send_file
I have a form_remote_tag that calls a method to print out a csv file

Yet another send_data :image question...
Guys & gals,
I''m also learning RoR (using v2.3.4). I''ve got a basic scaffold
working for image file creation, and - to a point - image file
display.
The send_data function is working in my controller - no problem. The
model code is able to parse the uploaded file construct too.

Redirect/rendering out of xhr
Hi,
I have a link_to_remote to an action in my controller, which has an rjs file
associated with it. In the action (where @request.xhr? is true), I have
tried to redirect to another page or render to another page. When I do this,
the log says all the redirections/renders were successful, but I remain on
the same page. My rjs file at least does not execute though, which is good.
