Rendering Partials w/Collections - is there a way to find the position?
This seems obvious, but I wasn''t able to find info on it easily. If
you are rendering a partial from a collection:
<%= render :partial => ''message'', :collection => @messages %>
Is there a way inside the partial to tell what item in the collection
you are on? For example, if I am in the first element in the
collection, I want to do something different?

AR to_xml problem with associations, Builder::XmlMarkup#to_a
When I do a to_xml(with a block) on an association of a model I got a
Builder::XmlMarkup#to_ary should return Array
Example that does not work.
@intervenant = Intervenant.find(params[:id])
output = @intervenant.to_xml( :skip_types => false, :dasherize =>
false) do |xml|

Reported timing aren't thread-safe, are they?
I was taking a look at the implementation for reporting the time spent
on each part of an action processing.
Rails, by default will report timing for the view and db (ActiveRecord).
Both use class attributes for storing the timing (or accumulating them
in the case of AR), which are shared among all threads.
This is fine if you''re deploying using the fork approach, like done by

FerretHash
Dave, thank you so much for the 0.11 release(s). You have solved many
problems for me. As part of my appreciation for your good works, I am
offering up for public consideration a silly little class that I wrote.
(Code is below.) This class offers a simplified Hash-like interface to
(a very restricted subset of) Ferret. Hence I call it FerretHash.
FerretHash comes with its very own pet Ferret

Strange Array behaviour
I''m having a strange thing when using the Enumerable extensions for
Rails:
Have a look at the following code:
class Invoice < ActiveRecord::Base
has_many :invoice_lines
def total
invoice_lines.sum(&:total)
end
end
class InvoiceLine < ActiveRecord::Base
belongs_to :invoice
def total
amount * price
end
end
Now, when calling invoice.total, I get wrong

Suggestion for improving value_to_boolean column conversion
Hi fantastic rails core developers.
Speaking of version 2.3.5:
I find it rather error_prone that values such that "some text" is
silently converted to false when stored in a boolean DB field.
Among other things it means that assign "some text" to boolean fields
on a model will not generate any validation messages (it will silently
be converted to false).
I think it is like

Model with method_missing - rails 3, ruby 1.9.2 raises exception
Say you have two models Post and Author.
And Post has_many :authors
Finally, method_missing is overridden in Author.
Then if you do
Post.limit(1).first << Author.limit(1).first
You get an exception Author does not define :to_ary
Or has there been a change in rails 3 that I have completely
overlooked while migrating my app?

CollectionAssociation shadows Enumerable#count
Hi all,
I realize this behavior is by design, and in some respects the right thing
to do. It also pre-dates the addition of Enumerable#count. I''m wondering,
however, if it''s possible/desirable to allow the caller to access the
Enumerable versions under certain conditions. I originally wrote the up as
an issue, but was informed this would be the better venue. I''m

Fallback for partial_paths on rendering process
Hi, I have an application that uses single table inheritance.
Very simple stuff:
class Place < ActiveRecord::Base
class City < Place
lets say I have a City on the @place
whenever I try using the
render @place
I will get an error, saying the templace cities/city doesn''t exist
but I do have a places/place template.
Is the any nice way to add this fallback for the base_class

Association collections problems
Hi all!
I find association collections to be quite hard to understand and use.
I have a Leg class that has_many :choices, and a Choice class that
belongs_to :leg. In a controller I want to update both a Leg and its
Choices. If I do it like this:
@leg.choices.update params[:choice].keys, params[:choice].values
It updates the database directly (or more specifically only updates
records that

Are Ducks Hibernating ?
Dears,
Remembering last value in a select box don''t work for me as :
Controller :
@years=(1970..2005).to_a
Form:
<%= select_tag "year", options_for_select( (2001..2005).to_a,
@params[:year] ) %>
I had to write
<%= select_tag "year", options_for_select( (2001..2005).to_a,
@params[:year].to_i ) %>

Noob Understanding Collections
Okay, I''ve had some success rendering partials and felt I''d try
something more interesting with collections.
I have a query run by my model, which works. When I run it from the
console I can see all of the data I want. However, bringing that
into my view isn''t working the way I think. So obviously I''m
thinking wrong, but I can''t see where my

if I call Programmer#projects.clear, it will delete_all the joining

assignments to get destroyed instead so that their after_destroy
callbacks get called. It would be simple to

useful bit of code (hopefully)
Hi,
I often find myself using bits of code like this inside ActiveRecord,
perhaps it''s useful for others, or others can improve on it:

# santize input before actual validation is called
# this uses the little methods defined below
