I kept getting “undefined method ’+’” when trying to add tags to the photos. for some reason it doesn’t like the line:
@photo.tag_list += ’,’ + params:tag
however @photo.tag_list.add(params:tag) will work in place of this.

Just looking at this – it looks like the tagging library has gone through some updates… I’ll add a page describing what I’ve found, but in the meantime, your fix works, as does
@photo.tag_list.names << params[:tag][:name]

I saw the note:

I had to use ’@photo.tag_list.names << params:tag’ because when I just used :tag, I was getting a comment added to the tag along the lines of Map!WashHandsWithIndifference or something like that…
Now to trouble shoot the delete function. It is deleting the tag—however it doesn’t update the page.

grr…
a feature of this forum editor is that it is hiding the ‘colon’ ‘name’ that I was placing after ‘colon’ ‘tag’

Try putting your code inside <code></code> tags.

Even after downloading the latest version (dated November 23, 2007) of the source code from Google Code [ http://code.google.com/p/railscoders-net/downloads/list ] the ‘add a tag’ code still wasn’t working.
I eventually managed to get it to work by changing the file ‘app/controllers/user_photos_controller.rb’ as follows:
def add_tag @photo = @logged_in_user.photos.find(params[:id]) # changed to reflect latest version of acts_as_taggable_on_steroids @photo.tag_list.add(params[:tag][:name]) if @photo.save @new_tag = @photo.reload.tags.find_by_name params[:tag][:name] else render :nothing => true end end
In particular, changing the following line:
@photo.tag_list.add(params[:tag][:name])
Hope this helps someone out there.
Kind Regards
Walter

I went with this add_tag code (hoping pre tags
preserve newlines, I don’t know this textilize
stuff):

      do_update = false
      if (tag_name = params[:tag][:name].strip).blank?
        # Ignore empty tags
      elsif @photo.tag_list.index(tag_name)
        # It's already there
      else
        @photo.tag_list << tag_name
        if @photo.save
          @new_tag = @photo.reload.tags.find_by_name(tag_name)
          do_update = true
        end
      end
      if !do_update
        render :nothing => true
      end
