Monkey Patching a Plugin

rubyonrails-talk
1

I am using a plugin that adds a method to ActiveRecord::Base. The added method is called self.create_or_update. I need to monkey patch this method. I tried in lib/ config/initializers and in environment.rb, but the one in the plugin is always the one that is run.

Where do I put my version of the method so that it overrides that of the plugin? I only use this method when running a rake task, so that may have a bearing on the issue?

Thanks, Ahmed

Showing us what you've tried would be a useful starting point.

The plugin is db-populate

in vendor/plugins/db-populate/lib/create_or_update.rb: class ActiveRecord::Base   # given a hash of attributes including the ID, look up the record by ID.   # If it does not exist, it is created with the rest of the options.   # If it exists, it is updated with the given options.

Edit the plugin. It's your source.

Submit what you did to its maintainer...

I agree with this. Submit the patch. If he says no, fork the plugin yourself on github and maintain it. :slight_smile:
