Dear Gurus on Rails! How do I change the behaviour of one method in ActiveRecord::ConnectionAdapters::SchemaStatements ? Full story: I''d like to mangle ActiveRecord::ConnectionAdapters::SchemaStatements so when it creates a new sql table, it also (optionally) creates my created_at, deleted, key_id, session_id etc columns that I use on basically all tables. It would not be DRY to repeat

Hi, We have experienced some problems with ActiveRecord::Base class of Ruby-Rails. We are building a web-application based on the Ruby-rails framework and the web-application needs to access to difference databases, so we do not pre-define our database accesses in the database.yml file. In fact, we are using the ActiveRecord::Base.establish_connection() to connect to our database, the function

Hi all, I am in the process of adding Migration support to the Ingres ActiveRecord adapter and have run in to a problem. During the call to create_table the Ingres adapter some how causes ruby to blow the stack and coredump/segv. I have tracked down the problem down to "add_column_options!" in "lib/active_record/connection_adapters/abstract/schema_statements.rb".

I still want to get this into Rails for all connection adaptors, but for now I''ve hacked my own addition on for just PostgreSQL. The following code extends every Column object returned by MyModel.columns to support a new #required? method, which indicates if the column may or may not be null. The following is a huge hack - suggestions on a cleaner way to add this functionality

I need to bootstrap my database when creating schema. My model class and migration class are the same. When I trying: ClassName.create :foo => ''bar'' in migration I got: undefined method `create'' for #<ActiveRecord::ConnectionAdapters::PostgreSQLAdapter:0xb75a357c> How to avoid this? I think the same class names causes problem, but I can''t change

Is there any way to set database columns to auto update a timestamp column on update? Can I do something like t.column "timestamp", :datetime, :default => :current_time, :null => false, :on_update => :current_timestamp or do i need to just use custom sql like sql = "ALTER TABLE `table` CHANGE `timestamp` `timestamp` TIMESTAMP ON UPDATE CURRENT_TIMESTAMP NOT NULL

Regards! During the use of areski a2billing software I'm getting same problem all the time. Actually, after 15 minutes of speaking to someone over calling card, connection brakes.

While this permits the code to function without crashing, it doesn''t actually make
