ActiveRecord::Optimizations 0.0.2

July 20th, 11:27pm, Zach Dennis

This includes some of the optimizations for the ActiveRecord::Base. This release only supports the MysqlAdapter, although other adapters will be supported in upcoming releases.


Require the two files in the lib/ directory and then create records using:

Model.create array_of_hashes


class LogEntry < ActiveRecord::Base ; end
LogEntry.import [ { :log_entry_name=>"Name" }, {:log_entry_name=>"Name2"}, ... ], :optimize=>true

Using the optimized create method will return the number of inserts performed, rather then an array of LogEntry objects. This currently skips model validation.



- add some documentation to the updated methods for ActiveRecord and MysqlAdapter
- renamed the create optimizatin to import. Multi-value inserts can be obtained using ActiveRecord::Base.import


- introduced updates to ActiveRecord::Base.create to support multi-value inserts


- model validation on imports
- postgresql support for imports
- ability to use regular expressions for db searches
- ability to use db functions
- temporary table support
- memory table support
- complex update with on duplicate key update support
