Getting rails tagging plugins to work makes me Hulk-angry

Answer 1

I have used mbleigh's acts-as-taggable-on, and the basic procedure goes:

1. Add config.gem "acts-as-taggable-on" to environment.rb
2. Run rake gems:install
3. Run script/generate acts_as_taggable_on_migration
   • Do any customizations on the migration you might want (you probably won't need to).
4. Run the migration, rake db:migrate
5. Add acts_as_taggable_on :your_desired_tag_names to your tagged model (pluralized).
   • I.e. Photo model has :colors tag.
   • If you are getting a NoMethodError, you may have skipped this step.
6. To set the models tags, use photo.color_list = 'abc, 123, def, 456'
7. Save the model: photo.save
8. List the tags: photo.colors
   • You might have to reload the model from the database for the photo.colors method to be available.

Check out the acts-as-taggable-on readme for more instructions/examples.

Crazy World!

I also managed to get acts_as_taggable_on_steroids working today...

The missing link was that you needed to add this to ApplicationHelper:

include TagsHelper

This was mentioned in the readme but only under the "Tag Clouds" section so it wasn't clear that you needed to add it for any of the methods to be recognized in the first place...

Kudos to this blog post's comments for helping me put the pieces together: http://www.fousa.be/blog/integrating-acts-as-taggable-on-steroids-in-your-rails-app
