Hi all, I've followed your list for sometime now and found always it
to be a great resource. I ask your help on this one after searching
for a solution all around to no avail.
I have an application where I used anaf in a model with children;
however as the number of children grew I noticed it was slowing up
quite a bit. After some analysis I found that when updating values for
one child anaf was doing validations on ALL chldren, which by then was
numbering in the thousands.
To illustrate my point I created this example:
class Language < ActiveRecord::Base
has_many :phrases
accepts_nested_attributes_for :phrases
end
class Phrase < ActiveRecord::Base
validates_presence_of :value
belongs_to :language
def before_validation
print "\nValidating: #{self.value}\n"
end
end
$ script/console
Loading development environment (Rails 2.3.5)
>> lang = Language.first
=> #<Language id: 1, name: "Italiano">
>> lang.phrases
=> [#<Phrase id: 7, value: "Buona notte", language_id: 1>,
#<Phrase id: 10, value: "Ciao", language_id: 1>,
#<Phrase id: 11, value: "Prego", language_id: 1>]
>> lang.phrases_attributes = [{:id => "7", :value => "Buon giorno"}]
=> [{:value=>"Buon giorno", :id=>"7"}]
>> lang.save
Validating: Buon giorno
Validating: Ciao
Validating: Prego
=> true
I expected in this example to see validation only on only one phrase
{id=>7}, but you can see it did it for all three.
I don't think this is expected behavior, right?
if so, can you help me find what I I'm missing?
After looking up at the code for anaf I suspect the issue may be in
autosave, but after a week trying to solve this I'm stumped.
can you help me?
Thanks in advance, Jose
