Prevent users from entering urls
How could I make it so that links on my page could link to a controllers
action, but if the user manually entered the url, it would redirect them
back to the main page? Is this possible?
Thank you,

How do I update a div''s content in the controller?
Without using an RJS, is there a call I can do in the controller? All I
want to do is this statement, but in the controller:
new Effect.toggle(''notifier_nav'',''appear'', {duration:12.0});
Thanks,

Using Application.rhtml as layout for all controllers
I put my nav system in application layout. that way any controller
loading will have the nav system. I have one problem though - the <%=
yield %> is in the body, so how would my controllers specify other css
files?
my application layout would look like this:
<html>
<head>
title
css include
javascript include
</head>
<body>
nav system
<%=yield%>

Navigation techniques, everyone?
I''m rewriting the code to my first app. I want to reuse a lot of it,
but tidy it up a lot. The first thing I will tackle is my nav-bar.
Throughout a user''s experience on my app, I want it to reload as little
as possible (I''ll have about 7 or 8 controllers with about 70 actions).
So, I''ve thought of a few ways of doing it, and was wondering if you

How to upload all images in a folder?
Instead of making a form to upload one picture at a time, I''d like to
have the File Column plugin accept a directory, and have each picture be
uploaded and thumbnails created (w/ RMagick).
Has anyone done this?
Anyone have a good idea where to start if I were to do it on my own?
Thanks,

Call action & display nothing?
Can you do a periodically_call_remote to an action but then not display
any new view? say the new action was called ADD. I don''t want to do an
rhtml file for add, and I don''t want to render anything in the
controller... I want to leave the page as it is. How is this done?
Thanks,

Mouse Location
Is the only way to get the mouse location by using javascript? Or does
rails do it for me?!? :)
Does anyone have a simple script that they use? I''m trying to put a div
right where the mouse is clicked on a link... so I''m looking for it to
work like this:
a hre f=. onclick=Element.setStyle(''title_login'', {left:
MOUSEX,top:

Why does no one like render_component?
Maybe I''m missing the point?
Lets take for example albums of pictures. If I have a scaffold for
each, and I''m showing an album, what if I want to list all of the
pictures that are in the album?
Surely, I''d want to call the List action in the picture controller.
render_component would do this perfectly. But we''re told not to use
render_component. So

RJS problem
I have an odd problem while trying to use a simple rjs.
_test.rjs : page.alert "test"

When I am attempting to view controller/test the page comes as if it was a
text file.
So i am actually seeing:

adding class or id tags to tags like linkto and form
I''m trying to figure out things like this by myself so I don''t bother my
developer and slow him down. How do I add class or id css attributes to
tags like this:

<%= link_to_remote "My Profile URL", :url => { :action =>
"send_profile_url", :id => @user.id } %>

How can I minimize SQL queries
I have users, who have friends that are also users in mysql database.
I have a foreign key for both users, so that I can reference their data
directly. My problem is displaying friends. My for statement would
look something like this:
for i in(0..@user.friends.length)
puts @user.friends[i].user.name
end
so @user is the user that i''m displaying friends for... .friends are the

Custom action on Active Record Validation Failure?
Instead of having it highlight the bad fields when you enter in a record
that fails validation, is there a way to make it do an action? I''m
looking for something like this:
validates_uniqueness_of :user_id,:url => {:controller => "headline",
:action => "index"}
so that on failing the uniqueness check, it would go to the headline
controller.

Ajax Tabbed Browsing
I was wondering if anyone has done this, namely make tabbed browsing
exactly like a web browser, but have it within the page.
I would like to make a search function that updates a section of the
page with the results, as well as makes a new tab that displays those
search results. Then, if a user did 5 searches, there would be 5 tabs.
Each tab would hide the other 4 results and show the

handling file uploads
hey guys,
the way i''m handling file uploads is no good, but i''m not sure what
the best way to go about it is. right now my approach is to use
FileUtils.mv to move the uploaded file to the directory i want it in.
this approach doesn''t work well because sometimes the uploaded file is
just an IO object instead of a temporary file (apparently small files
