White Screen of Death
Hello, I''ve heard these words to describe a RoR application returning an empty page. This happen from time to time even here, in the forum. That is the cause of this misbehaviour ? Is it related with something external to RoR itself ? What is the solution to avoid the WSOD ? -- Posted via http://www.ruby-forum.com/.

Every time I want to use it for debugging purpose (evaluating $ or $$ calls for example) I get a message stating that a script on the page must be stopped. If I stop that ''script'' (which script it is ?) the console is

File.open behavior for ActiveRecord, to ensure save after manipulation?
File.open in core Ruby is nifty, in that it automagically closes the file when you''re done using/manipulating it. I''m wondering whether there''s something like that for ActiveRecord? So you can do: AR.find(23).open {|ar| ar.foo = ''bar'' ... } And ar.save would be called when the block closes. -- -Alder

Generating a unique id ?
Hello, I need to generate a unique ID, so far I''ve unit tested this under 100000 iterations and it seems to work : now.to_i.to_s + ''-'' + now.usec.to_s + ''-'' + rand(1000).to_s Is there a better way ? Thanks Notes : 1) without usec, few percents of generated values are not uniques 2) the id generated is a string so the presence of

Exploring ActiveRecord::Base#serialize
Hi I was recently taught about the useful ActiveRecord::Base#serialize. It''s very useful for persisting arbitrary objects through the regular database. For example, say you want to store a Set of all the years a Convention took place. You do: class Convention < ActiveRecord::Base serialize :years, Set end This effectively creates a Convention#years attribute, which is a set: you

ActiveRecord::Base::find_for_create_modify
Hi, for some models I found that it''s easier to share the controller new and update code just to share the view code. At the front of every such action function I have to lookup if the object already exists, if so "find" it from the database and update the "attributes=". If there is no such object, "new" it with the attributes I''ve got from the

How should I select rows from a join-model based on more than one association?
A concrete example: We''re building a system to organize the information about workshops being held in various conventions. A convention has more than one workshop, and each workshop can be held in more than one convention. Also each workshop has a host, who is specific to a workshop being held in a specific convention. For example, Matz may host an "Introduction to Ruby"

create separate plots by factors
Hello, I am attempting to create several plots based on "site" (~300 total) and am having trouble with the code. I simply want to create a plot using the code, plot(year, peak), for the following dataset. I would like for each site to be plotted on a separate page and the plots saved in a directory. Would a "foreach" loop work? I tried a "by" statement, but

How to SELECT from multiple talbes with AR#find and associations?
So I want to SELECT from multiple tables, so as to be able to do "SELECT FROM foo, bar WHERE foo.id=bar.id AND bar.baz=23". How do I do it with AR#find? Also, I need this for associations. has_many et. al. have :finder_sql, which is nice, but feels like a Pyrrhic: it''s basically doing the association in pure SQL, defeating the purpose of AR. -- -Alder

How do you delete a session variable?
Hi Let''s say we set session[:foo] = ''bar''. Now we want to remove the :foo key completely. How do you do that? Appearantly, session is a CGI::Session [1] instance, so it doesn''t have #delete like Hash. I tried: session[:foo] = nil But then debug(session) shows an empty :foo key. I''d like to remove that key, as my session is already pretty crowded. Is

Running Rails tasks by schedule, instead of an HTTP request.
Hi there I''m considering Rails for a new web-application planned to be built from scratch. The application has an extensive web front, and in fact most of the application is interfaced through that front and engaged through clients'' HTTP requests (i.e. the conventional way web-applications and "dynamic web-sites" work).
