Google Chrome and Iron

I'm sure most of you have heard of Google's new WebKit based browser "Chrome". Well, a German company has released a more privacy friendly version called "Iron", with the browser usage tracking removed. Their site is written in German, but here is a translation thanks to Google's Language Translation tools.

I haven't had a chance to try it out yet, but I'm glad someone is taking advantage of the open source nature of Google's offering.

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).

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...

NHibernate hbm xml template

Friday, I added an NHibernate mapping.hbm.xml template. I mainly wanted to show that the code generator can be used for other purposes than just Castle ActiveRecord, and NHibernate is an easy target. Jim R. has requested that I add HasMany (aka ManyToOne) mapping properties and attributes. I think this is going to push me to refactor the schema extraction code. Some of my future goals for the application are: 1. Full Model Generation (list of children, whether directly or indirectly through a many-to-many table) 2. User controllable plural-to-singular mapping. 3. Multi-database, using the Database Provider Factory. 4. Refactor code generation into a library (as I do with all projects) 5. Command-line code generation (supply at least a template and a list of tables) 6. Templates for other ORM tools (pure NHibernate, Rocky Lhotka's CSLA Business Objects, etc.)
