[Rails] A dumb question on extracting a value from a hash
Hi,
I have the following code fragment;
@comm_type = Communication.find_by_sql(''select id from
communication_types where upper(description) = "EMAIL"'')
Which results in
>> @comm_type
=> [#<Communication:0x39a0f60
@attributes={"id"=>"4"}>]
But when I try to test an ActiveREcord against this it doesn''t work;
@recipient.communications.each do |comm|
if comm.communications_type_id == @comm_type
@email_address = comm.code
end
end
What do I need to write to get at that value in the hash. Sorry it''s
such a dumb question :~(
Cheers,
Eric.

Hi Ezra, Nope - I tried that (and a few other combinations) @comm_type.id is returning the id of the hash not the id within the hash. I''d have expected to get the attribute 4 too, but noooo Eric.
