Hacking FireFox 2 Menus

Today, I was inspired to hack the context menu in Firefox 2.0, removing "Send To" and "Send Image". I googled for a solution, and found step-by-step directions for Firefox 1.0. So, I started digging, and the over-all instructions were good, but I only needed to comment out the menu options in browser.xul, and not touch the javascript in browser.js. The original instructions were a bit vague, but in the end, it worked!

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...

Features of the Code Generator

I just updated my code generator to optionally generate validation attributes. This simple change includes App.config file entries for all check boxes, and a new checkbox for "Validation" - aka validation attibute generation. While I was making this change, I realized that I really need to pass a CodeGenerationContext object to the DbTable, DbField and ModelGenerator classes. The requester can populate the context, and pass it to the code generator. Anyway, enough about the code, let's talk about the templates. I made a simple template this weekend to generate a DataGridView column array, suitable for databinding. I'm sure my new template will need some tweaks to handle Foreign Keys better (it currently just displays them as TextBox). Let's look at a template. ##FILENAME:PR_${table.GetClassName()}_Insert.sql ## ## Generate a SQL stored procedure to insert a record into the ## specified table and return the newly created primary key ## ## FUTURE: The generat...
