I have a complex graph of ActiveRecord entities that I want to load with one big honkin'' join query to avoid ripple loading. It''s for a report. However :include doesn''t get me all the way there because I want to load parents of parents (or children of children). I don''t mind doing the SQL by hand but I''m not quite sure what to do to get the result

What''s the best way to handle a requirement that shows up as a sub-requirement requirement in other features? For example let''s say users can enter dates in various forms throughout my application. There is one set of global rules specifying the formats in which dates may be entered, and how they are interpreted. I put that in one feature. In various other features, like

Anybody use Resin''s (http://www.caucho.com) FastCGI support with Rails? I''m seeing performance very close (almost the same) to what I''m seeing with Lighttpd. Nothing scientific but just a quick test using Apache''s wb and JMeter. (Might be interesting to other Java/Rails folk or Java/PHP/Rails folk. I have no connection to Caucho and the tests were done with

...low as a context diff. With this minor diff applied, the heading proper is included in a minipage environment of appropriate size, which results in line breaks introduced in the heading instead of bumping into the surrounding keywords for somewhat longer headings...

I've been using R for the last few weeks, but not with much success. If I try sourcing test.R from the 'class' package, I get this error: Error in .C("VR_knn1", as.integer(ntr), as.integer(nte), as.integer(p), : C/Fortran function not in load table I checked the class.so file, and sure enough VR_knn1 is there. Why can't R find it? By the way, I'm running RedHat Linux,

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

Dear developers, I wonder would you consider making a save to a graphics file format (as opposed to ps)? What prompts this is that we have just finished my wife's thesis using R heavily for stats and graphs. The combination of latex, bibtex and R generated .eps worked a treat and we were very pleased with both the final outcome and the efficiency of gernerating it, especially when all the

I''m having the following problem: With the format as html, the output of cucumber stops coloring successful steps green after step #100. This last line in the HTML is: <script type="text/javascript">stepPassed(100)</script> Steps 101 -n are colored grey. The <body> tag is not closed but all steps are displayed. When running with ''format

Hi, Not sure where to address this question ... but I guess this is a good start. I am a freelance Rails developer - and have been developing Rails apps professionally for about a year now. I just want to get an idea of what you other freelancers charge yourselves out at. I have been charging the equivalent of about $28/hour, but get a sense that I could/should charge a whole lot more. I am

I''m having a problem with Rcov 0.40 and Rails 1.1.2. When I run all my tests (unit, functional and integration) with rcov weird things happen with some but not all of my functional tests. The tests will blow up with an ''ActionController::UnknownAction - no action responsed to my_action'' error. After investigating and adding some print statements, it turns out
