ruby script/plugin install git://github.com/bgetting/acts_as_mailchimp.git

Examples

The following controller examples illustrate how to use acts_as_mailchimp:

To add a user to a mailing list called “weekly_newsletter”:

    @user.add_to_mailchimp("weekly_newsletter", false)

To remove a user from a mailing list called “weekly_newsletter”:

    @user.remove_from_mailchimp("weekly_newsletter")

To update information about a user Rails 2.1 or below:

    previous = params[:user][:email]
        if @user.update_attributes(params[:user])
          @user.update_mailchimp("weekly_newsletter", previous) if @user.email != previous
        end

To update information about a user Rails 2.1 or above:

        if @user.update_attributes(params[:user])
          @user.update_mailchimp("weekly_newsletter", @user.email_was) if @user.email_changed?
        end

Keep in mind that you these update examples do not make calls to the MailChimp API unless the user changes their email address. If you are integrating first_name and last_name fields as well, you will need to adjust your controller code to update MailChimp when they change either of these values as well.

There is currently no advanced documentation for this plugin.
