Articles appear too many times - ruby-on-rails-3

Question

I started using Ruby on Rails a few days ago, and I have a problem with the each do loops.
Here's my AccueilController's code :
def index
#postsTest = Post.last(1)
#articles = Article.last(1)
#articlesList = Article.last(2)
respond_to do |format|
format.html # index.html.erb
format.json { render json: #users }
end
Here's my application.html.erb code :
<div id="container">
<div id="col1">
<%= render :partial => 'shared/listArticles', :collection => #articlesList %>
<div class="clear"></div>
</div>
<div id="col2">
<%= yield %>
</div>
</div>
</div>
And now my shared/listArticles's code :
<% #articlesList.each do |article| %>
<div id="blocArticle">
<div id="pic">
<%= image_tag (article.photo.url(:thumb)) %>
</div>
<div id="contentArticle">
<div id="titleArticle">
<%= link_to article.title, article %>
<div class="clear"></div>
</div>
<div id="contentArticleDesc">
<%= link_to article.desc, article %>
<div class="clear"></div>
</div>
<div class="clear"></div>
</div>
<div class="clear"></div>
</div>
<% end %>
And my problem is that if I write #articlesList = Article.last(2) then the last two articles will appear two times; if I write #articlesList = Article.last(3) then the last three articles will appear three times etc...
Of course, I would like that each of them appear just one time.
Does someone have any ideas about the source of the problem ?

Answer 1

You're rendering a partial with a collection, therefore Rails calls the partial for each item in the collection. Remove your loop from the partial view or remove the collection param, don't do both!
