Pass params on index_path route

Question

I'm having a helper for displaying the tags of a post

# Show action
%p Tags #{ link_tags @post }

# Helper
def link_tags post
  raw post.tag_list.map{ |t| 
    link_to t, posts_path(tag: t.name)
  }.join(', ')
end

However I'm getting an error on screen

undefined method `name' for "ruby":String

How can I fix this? As a side note the code on my sidebar (where I list all post-tags) where I tried to copy from works fine

- tag_cloud Post.tag_counts, %w(tag) do |tag, css_class|
    = link_to tag.name, posts_path(tag: tag.name), :class => css_class

Answer 1

post.tag_list will give you an array of tags as strings.

What you are looking for is probably post.tags which should return an array of ActsAsTaggableOn objects.
