The Rails Way

There is an excellent article on recommended coding practices "The Rails Way" . The authors are espousing a commonly held coding practice - use base classes or mix-ins (Modules in Ruby) only when code would otherwise be repeated. This reinforces the DRY (Don't Repeat Yourself) philosophy that Ruby encourages and facilitates.

A helpful reader offers further explanation for those Rails programmers who have not dug deeply into Ruby yet at Artistic Coding.

Ruby is such an amazing and flexible language, but my "Day Job" is .Net, so I can not wait for Ruby.Net, Ruby CLR (or maybe here), or whatever works. Ruby.Net and Ruby 2.0 (see YARV). Microsoft is working on IQF (Integrated Query Framework), which will try to offer .Net users the same ease-of-use and elegance that ActiveRecords offers (ActiveRecords is a part of the Rails framework, but can be used separately). If Mono also implements IQF, I will be interested. We shall see.

How does Rails scaffolding select HTML input tags?

Recently, a reader saw my fix for SQL Server booleans, and asked me a followup question: why does Rails display a yes/no selection instead of a checkbox? The short answer is look in {RUBY_HOME} /lib/ruby/gems/1.8 /gems/actionpack-1.10.2 /lib/action_view/helpers, but your path may vary depending on whether you are using gem, "edge rails", etc. Anyway, look in the file "active_record_helper.rb" for a method called "all_input_tags", and notice that it calls "default_input_block" if you don't supply an input_block. Now notice that "default_input_block" creates a label and calls "input(record, column.name)" which in turn calls "InstanceTag#to_tag" which finally looks at the datatype and maps boolean to a select tag. Perhaps a wiser Rails explorer can provide us with the rationale for this, but I guess we could add a MixIn for InstanceTag that redefines the to_tag() method, or just do a dirty and unmaintainable hack l...

Destiny 2 - The Corrupted Nightfall

 == Overview == This Dreaming City Nightfall is already considered one of the most irritating strikes, in part because of bugs that sometimes prevent players from proceeding to the next encounter.  Notable bugged areas are the transition from the Elevator to the Knights Steps, and after the passage, the temple sometimes doesn't reveal a way to the shadow realm where you will take your leap. Important Note: After a "de-buff" from Particle Deconstruction, shoot the boss in the head!  It is quite effective, and can melt her with some coordination. Champions: Unstoppable and Overload Shields: Arc, Solar and Void (many shields!) Don't place your well in the open where boss can snipe the sword!  She will break your super. Pass the "Relic" (Orb) twice to maximize damage. == Loadouts == General: * Add Taken spec to every weapon Titans: * Bottom Tree Solar + Path of the Burning Steps or Phoenix Cradle * Sentinal Shield + Ursa, Aeon Gauntlets Warlocks: * Stasis + Blea...

Updated ActiveRecord Code Generator

Today, I updated the ActiveRecord Code Generator a bit. I checked in changes to use primary and foreign key details from INFORMATION_SCHEMA. The original code used naming conventions to decide what various fields were used for - ID = Primary Key, Field_ID = Foreign Key to table Fields. If you want to use naming conventions, let me know and I can add a setting in App.Config to allow this (along with any "real" key constraints).
