I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

This might be a problem with postgresql, but I''m not sure. In a migration I have renamed a table so I wanted to rename a sequencer as well. It looks like: execute "ALTER TABLE global_vacations_id_seq RENAME TO vacations_id_seq;" execute "ALTER TABLE vacations ALTER COLUMN id SET DEFAULT nextval(''vacations_id_seq''::regclass);" But the process of

I have strange error that happens after couple of hours. Some instances start to respond on any request with status code 500. Log file unicorn.stderr.log gets populated with this error: app error: undefined method `each'' for nil:NilClass (NoMethodError) /usr/local/lib/ruby/gems/1.9.1/gems/rack-1.1.2/lib/rack/utils.rb:267:in `initialize''

Given a field in database defined as "discount_rate numeric(3,1)" I found it not very usable for presenting it directly. For example, if there''s a value 5.00 it will render in <%= text_field ''model'', ''discount_rate %> as "0.5E1" which is not very friendly to user.

As soon as I use Model.find(:all, :include => [...], :limit => 3) I loose associations and can''t do :conditions on joined tables. I''m not able to do pagination in such association. Only solution I came up with is this beast: # I set up a paginator: @reos_pages = Paginator.new self, Reo.count(conds.join('' AND ''),

I want to use ActiveRecord outside of Rails to do processing on large tables. I want to be able to process the rows as they are retrieved rather than having to store the results in an intermediate array. Any suggestions? Looks like I could hack the adapter to provide an accessor to the underlying DBI handle. Anything cleaner than that?

Hi, I noticed a problem when switched from SCGI to Mongrel. At very first moment my application goes to url /start/dashboard/overview which in Mongrel gives me 404 Not Found error. As soon as I changed it to /appstart/dashboard/overview it fixed the problem. -- Kamil

Having a dumb model object like def MyModel attr_accessor :property def initialize @property = Array.new end end when it is used for for interaction by "@object = MyModel.new" and then used in view as <%= text_field ''object'', ''property'' %> shoudn''t it be rendered as?: <input type="text"

After searching arround I found a quite smart solution to me for binding form fields to model in an active way. I use aggregations with single value objects such as class Percentage attr_accessor :value def initialize(value) @value = (value.is_a? String) ? value.tr('' %'', '''').to_f : value end def to_s return unless value

Hi, I was having problem with disappearing sessions when storing them in memcache and when runnning as mongrel cluster in production environment. I''ve created a patch and it seems it''s now okay.
