The name of the class is ActiveSupport::Inflector now, you’ll have to change the reference on the plugin. - Maurício Linhares [http://codeshooter.wordpress.com/](http://codeshooter.wordpress.com/) | [http://twitter.com/mauriciojr](http://twitter.com/mauriciojr) On Fri, Jul 3, 2009 at 9:45 AM, Rafael ---

Get inside the plugin code, look for where Inflector is being used and change it to ActiveSupport::Inflector. - Maurício Linhares [http://codeshooter.wordpress.com/](http://codeshooter.wordpress.com/) | [http://twitter.com/mauriciojr](http://twitter.com/mauriciojr) On Fri, Jul 3, 2009 at 9:54 AM, Rafael ---

Browsing through the acts\_as\_versioned.rb file I found the following: self.versioned\_table\_name = options[:table\_name] || “#{table\_name\_prefix}#{Inflector.underscore(Inflector.demodulize(class\_name\_of\_active\_record\_descendant(self)))}\_versions#{table\_name\_suffix}” Is it what I must change? ---

First check that the plugin doesn’t have a more recent version. I’m using it in a Rails 2.3.2 project fine (but I can’t remember if I patched it myself or not) Andrew T.

That same line in my version is: self.versioned\_table\_name = options[:table\_name] || “#{table\_name\_prefix}#{base\_class.name.demodulize.underscore}\_versions#{table\_name\_suffix}” I think you are using an old version and should upgrade > **[GitHub - technoweenie/acts\_as\_versioned: ActiveRecord plugin for versioning...](https://github.com/technoweenie/acts_as_versioned)** > > ActiveRecord plugin for versioning your models.
