Rails - Nov 2008 - Rails 2.1.2 => 2.2.2 Attempt to call private method

Hello All,

Controller code
---------
@dates = Q.find(:all,
:select => ''year(q.approved_at) as y, month(q.approved_at) as m, day
(q.approved_at) as d, count(*) as cnt'',
other conditions

View code
---------
<% y = '''' %>
<% for d in @dates
                if y.to_s != d.y.to_s

the new rails 2.2.2 says that

"Attempt to call private method

....attribute_methods.rb:236:in `method_missing''

How I should write my code, so I can select not only the Q table
fields, but also calculated fields ?

Regards,
Pavel

4: <% y = '''' %>
5: <% for d in @dates
6:                if y.to_s != d.y.to_s

also if I rewrite line 6 in the following way it works

6:                 if y != d[''y''].to_s

but it requires to change a lot of code

Don''t call it y. There''s already a method on object called y
(seems to
do yaml dumps). You might be able to get round that with

class Q < ActiveRecord::Base
  undef_method :y
# rest of that class here
end

yes, you are right .. I have renamed "y" to "year" and it
works
