Verifiers for [PATCH] 7308 (Add ActiveResource.update_attribute(s)) needed

Hi, I verified an old Patch by rwdaigle

The patch adds two methods to ActiveResource:

* update_attribute(attr, value)
* update_attribute(attributes_hash)

This is *very* useful on replacement of ActiveRecords with
ActiveResources, because, as you probably know, a very common
implementation of update method on restful controllers is as follow:

  def update
    @article = Article.find(params[:id])
    respond_to do |format|
      if @article.update_attributes(params[:article])
        flash[:notice] = 'Article was successfully updated.'
        format.html { redirect_to(@article) }
        format.xml { head :ok }

Please try and +1 the patch if you can
