How does this helper work? (agile book)
Hello,
Im trying to understand how this helper method works:
def hidden_div_if(condition, attributes = {})
if condition
attributes["style"] = "display: none"
end
attrs = tag_options(attributes.stringify_keys)
"<div #{attrs}>"
end
This is how they are calling it:
<%= hidden_div_if(@cart.items.empty?, :id => "cart") %>

InPlaceSelectEditor question
I''m attempting to use the example given in the Rails Recipes book chapter 2,
to create a select drop-down using the InPlaceEditor function (modified to
be InPlaceSelectEditor.
The example given works (a country list drop-down), but I''m attempting to
use it to display a list of items generated from an object in another table
that is linked to the table that I''m editing.

Where to place a global function
Hi all,
I have a little function called format_price(price) that simply formats the
argument as a dollar sign, dollar amount, dot and penny amount. Then, in
a .rhtml file, I could do this:
<%= format_price(item.unit_price * item.quantity) %>
But where do I put the format_price() function definition? The app couldn''t
find it in app/controllers/application.rb. Where do I put it

tag, content_tag: are nil-valued options ever useful?
In a number of places in my code I pass options whose value are '''' or
nil to one of the tag-generation helper methods. In the HTML this shows
up as, e.g.
<span class="">
Now, this can be pretty wasteful, but I don''t want to change my evil
ways. Thus I''d rather have the framework throw out these options than
do it myself. AFAICT, all tag

Best practices for conditional display in views?
Hi.
I am writing an application that has a lot of boolean conditional
display logic, like this:
<% if user.description then %>
<p class="css_class"><%= user.description %></p>
<% end %>
Often the displayed content is more complex than the above, and to clean
up my views I am trying to pull a lot of this sort of thing into
partials.
However, the problem

In_place_editor in a For loop
I''m using Ajax to create a list of items. Once these items have been
created the user can edit in place and delete them. I''ve got the ajax
working for delete and removing the element from the page, but the
in_place_editor_field doesn''t seem to like being in a for loop. I''ve
got in_place_editor working for single items, but what''s the syntax

[PATCH] helper to create fb css stylized table
I attached a rails helper implementation of the fb_table described here:
http://wiki.developers.facebook.com/index.php/Facebook_Styles
I included testing and comments. I hope you find it useful.
Curiously, it''s really a small extension of FBML.

Passing Ajax.InPlaceEditor options
I''ve followed the instructions in the Rails Recipe #1 and have the
in_place_editor_field working but now I want to tweak how it looks and

in_place_editor_field submitOnBlur & okButton=false options?
I have a few in_place_editor_fields working fine. I can access some of
the script.aculo.us options such as :cols, :save_text, :cancel_text, but
how do I access the okButton = false & submitOnBlur options? Basically,
I want no submit button, a cancel button, and the ability to submit when
I tab out of the field.
Is this doable without writing a helper? (avoiding digging that deep so

session[:return_to] for going back.
Hi,
Is session[:return_to] something Rails maintains to quickly go back to the
previous uri without having to keep track of the action name? Or, do we
have to actually set it in our actions?
Thanks.

Autocompleting InPlaceEditor
Hi,
I''ve created some extensions to script.aculo.us InPlaceEditor, allowing
the use of either server-driven, or local autocompletion. I''ve also
created new helper methods in Rails for this functionality.
My question is, is there any interest that I package this and make it
available as a plugin, or something like that?
Regards

JavaScriptGenerator Dead End
Hi All,
I posted earlier about a problem I was having with the various remote
view methods escaping all the javascript in my callbacks. I was quickly
informed that that''s just what they do, and offered some workarounds.
However, in actually working with this, I''m finding that this one little
thing is forcing me to write some REALLY ugly code. Where I thought I

Helper content_tag and Blocks
The content_tag helper allows you to do things like:
content_tag(:p, "Hello world!")
# => <p>Hello world!</p>
It can take in blocks, for functionality like this:
<% content_tag :div, :class => "strong" do -%>
Hello world!
<% end -%>
# => <div class="strong"><p>Hello world!</p></div>
Unfortunately blocks
