Rails Error Message - Incorrect Number of Arguments 2 to 1

I clicked the comment link (to post, not read, comment) in the Gem Enki jewels and he gave me this error message

ArgumentError in Posts#show wrong number of arguments (2 for 1) Extracted source (around line #27):

But I can not understand what are the two arguments that it sends. Please note that I already created one post without comment.

This is a controller action show

  def show @post = Post.find_by_permalink(*([:year, :month, :day, :slug].collect {|x| params[x] } << {:include => [:approved_comments, :tags]})) @comment = Comment.new end

this is the link I click in views / posts / index.html.erb to make a comment

 <li class="comments"><%= link_to(pluralize(post.approved_comments.size, "comment"), post_path(post, :anchor => 'comments')) %></li>

This is an error message on the screen. Any suggestions how can I try to figure out what is going on?

Rspec tests (Note, I did not create comments, so I don’t know why this was expected)

As Asolo noted, Enki defines his own helper post_comments_path . The problem is that Enki does not use parameter options, such as Rails helpers. Thus, form_for finishes passing the option :format => nil , waiting for the Rails style helper.

You can fix this by adding options = {} to the end of Enki post_comments_path or by specifying form_for an explicit URL:

 form_for(@comment, :url => post_comments_path(@post), :method => :post)

So, I was looking for your error, and this error appeared in me.

 app/helpers/url_helper.rb:9:in `post_comments_path'

I thought you might have declared this helper, but actually this is actually declared in Enki to check:

 def post_comments_path(post) post_path(post) + "/comments" end

So why you get the error of this argument. I don’t know why they would overestimate this, but they did.
Here is the source on github
