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 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});

How do you use :message with validation?

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,

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,

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:

RJS problem
I have an odd problem while trying to use a simple rjs.
_test.rjs : page.alert "test"
test.rhtml: <script><%=render_partial(''test'')%></script>
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:
<%= form_remote_tag :url => { :action => "send_url" } %>
<%= link_to_remote "My Profile URL", :url => { :action =>
"send_profile_url", :id => @user.id } %>

To Do list project?
I''m looking for a good web-based to do list app. Essentially, I''d like

since I can''t install Basecamp on a server I own. The information
being tracked in the list cannot be sent out of my intranet.
I would imagine that there are a couple of open source rails apps that

FK constraints overrated?
Hello folks,
I use to think that a relational databases without foreign keys
constraints enforced strictly by the RDBMS were no good, piece of crap,
data junk.
However, I''ve also learned the hard way that FKs constraints imposes
serious difficulties when moving data around, specially between
different DBs, or for loading test data or for upgrading DBs schemas, or
for porting DBs

TextMate and Tabs
Hello Everyone ~
Recently I have been moving Rails files between Mac, Linux, and Windows. As
many know the Windows Ruby version 1.8.4 doesn''t like tab characters. I
know in TextMate on the mac you can replace your tabs with spaces from the
Text > Convert menu, but is there a way to set it to do tabs with spaces
instead as you work? The preferences do not seem to have such a

It outlined adding the necessary database tables with a schema

Queries with has_and_belongs_to_many relationship
I was able to create a has_and_belongs_to_many relationship for my app,
but now I''m not too sure how to write queries for it.
Basically, I have a table ''courses'' that has_and_belongs_to_many

So I''m trying to figure out how I would find only the courses that
belong to a category that I specify.
