I’m trying to update a set of comments in my app. I’m trying to use ajax  
to do so and I’m running into problems. I’m getting the error below

undefined method `each’ for #Ratecomment:0x267ac80  
Extracted source (around line #2):

1:

  
2: \<% @comments.each do |comment|%\>  
3:   
4: 

|   
5: 

Hope someone can help.

######### controller code

def rate\_new

```
@furni = Furni.find(params[:id])
@comments = Ratecomment.new(params[:ratecomment])
if @comments.save
  Rating.delete_all(["rateable_type = 'Furni' AND rateable_id = ?",

```

@furnii])  
@furni.add\_rating Rating.new(:rating =\>  
params[:ratecomment][“rating”])  
@comments.save!  
else  
flash[:notice] = ‘Comment field can not be empty!’  
end

end

######### view code

  
\<%= render(:partial =\> “rate”, :object =\> @comments) %\> 

######### partial code

 \<% @comments.each do |comment|%\> \<%end%\>

- Currently \<%= number\_with\_precision(comment.rating, 1) %\>/5 Stars.
