You're trying to add a hash to an AR association... Rails doesn't like that :)

Take a look at the titleize() method and get rid of hashtag entirely...
http://api.rubyonrails.org/classes/ActiveSupport/Inflector.html#method-i-titleize

What is visible? If visible is related to the user's ability to see that topic
then it shouldn't be set in the topic itself.
You'll need an intermediate model (look up has many through) to handle that.
Ignoring that for now...
def create
name = params[:topic][:name].titleize
@topic = Topic.find_or_create_by_name(name)
current_user.topics << topic
redirect_to @topic, :notice => 'Topic was successfully created.'
end
