errors_for
Been playing with merb.
One of the helpers I liked in rails was on form validations. Found
this was real easy to port over, so I thought I''d share.
It doesn''t highlight the field with the error, but it gives that same
nice little div on top.
Say I had an articles controller
def create
@article = Article.new(params[:article])
@article.save!

Questions on writing plugin for merb
Hey all,
I am looking to write a plugin for merb and have a few queries about

plugin will require soap4r) as per any usual gem spec?
- If I want my plugin to add some new generate functionality? Is this
possible? If so, are there

Newbie - populating select list from db
Can''t seem to find an example of this anywhere - how do I populate a
select list in a form from a database?
I have a form to create a new task. The task is for a client, so there
should be a select list populated from my clients table. I thought this
would work:
<%= select ''task'', ''client_id'', Client.find_all, "id", "name"

kldload: Unsupported file type
Since updating to 6.3-RELEASE on two machines I see this message a lot.
It is printed whenever a kernel module is loaded.
The modules load OK. Nothing special or different about them.
It seems to be harmless, but any idea why it's started happening since
the release?

How to create a custom time select form element?
Hello,
I would like to turn a regular 24 hour time select input into a 12 hour time select with an additional AM/PM select input. For example:
Before:
[00..23] : [00..59]
After:
[1..12] : [00..59] [AM,PM]
I''m really surprised that this sort of thing doesn''t come standard in Rails. Has this been
done before? Is there a plugin or gem that I can install? If not,

Added associations but don't see generated methods
Hi,
I''ve got a Rails app working that includes two two classes, etc.:
Expense & Vendor. I eventually learned that the mental concept I had
of their relationship should be express in Rails as:
class Expense < ActiveRecord::Base; belongs_to :vendor; end
class Vendor < ActiveRecord::Base; has_many :expenses; end

Helpers in 0.9
I would like to start moving the helpers over into 0.9, I figure that
is something even I can do. But before I start I wanted to ask around
and see if these will be staying in merb-core, or if they should be
moved off to -more.
I want to start with the url helper and then get the js and css
helpers. I think these should stay in core personally. After that I
will probably try and get merb_helpers
