Hi Philip, I tried your code:
def create
name = params[:topic][:name].titleize
@topic = Topic.find_or_create_by_name(name)
current_user.topics << @topic
if @topic.save
redirect_to @topic, :notice => 'Topic was successfully created.'
else
render :action => "new"
end
end
But now I get this if a topic has already been created:
'Validation failed: User has already been taken'
> 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.
Visible will be used like a soft-delete, that only admin users will be
able to modify. By default all topics are visible, but if a topic is
against our rules :visible will be changed to false. That way it will
not show (to site visitors) and it will also catch any future violations
(as it's already been created).
> Take a look at the titleize() method and get rid of hashtag entirely...
Titleize only capitalizes the first letter of each word... I want to
remove the space too, so it because a #hastag :-)
