Association Extensions

Rails
1

Hi,
I’m using an assocation extension as follows:

module RequestFinder
def open
find(:all, :conditions => “buyer_requests.closing_date >
‘#{Date.today}’”)
end

def closed
find(:all, :conditions => “buyer_requests.closing_date <=
‘#{Date.today}’”)
end
end

with the following ActiveRecord

class User < ActiveRecord::Base
has_many :my_requests, :class_name => “BuyerRequest”, :extend =>
RequestFinder
end

In my tests I have a test to check the number of requests.

def test_number_of _open_requests
john = users(:john)
openrequests = john.my_requests.open
assert openrequests.count == 1
end
Although this returns an array with the correct values my problem is
that the count method is undefined. Does anyone know if thats expected
behaviour, according the Rails recipes books each of the assocation
proxy methods should be available on the returned object i.e. find,
create, count etc…

Thanks in advance,

John

john.my_requests is an association proxy (with the proxy methods
defined on it, including those in your extension).
john.my_requests.open is just a call to a normal find method, so
returns a bog standard array.

Tom,
With your clarification I’ve reread the rails recipes statement.
“These association proxies have access to all the same methods that
would
normally be defined on the associations, such as find( ), count( ), and
create( ).”

john.my_requests has these methods so this is correct.

Thanks,
John
