Question

I have a blog style site and under each article there is the usual ‘view’ ‘edit’ and ‘delete’ functions for users once they are signed in. The issue is when I click on ‘delete’ the link it sends you to the ‘view’ article page and doesn’t delete the article. Can’t figure this one out as the delete and view paths are different in my code but do the same thing…??

class ArticlesController < ApplicationController

  before_filter :authenticate_user!, :except => [:index, :show]

# GET /articles
# GET /articles.xml
# display the amount of article on the home page

def index
@articles = Article.published.page(params[:page]).per(6).ordered

respond_to do |format|
  format.html # index.html.erb
 # format.atom #index.atom.builder
  format.xml  { render :xml => @articles }
end
end


 # GET /articles/1
 # GET /articles/1.xml
def show
  @article = Article.find(params[:id])
  @comment = Comment.new(:article=>@article)

respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @article }
end
end

...

/controllers/articles_controller

# DELETE /articles/1.xml
 def destroy
@article = Article.find(params[:id])
 authorize! :destroy, @article
@article.destroy

respond_to do |format|
  format.html { redirect_to(articles_url) }
  format.xml  { head :ok }
  end
 end
end

views/articles/_article.html.erb

<div class= "art-links">
<%= link_to 'Read', article %>
  <% if can? :update, article %>
 | <%= link_to 'Edit', edit_article_path(article) %> |      
 <% end %>

 <% if can? :destroy, article %>
  <%= link_to 'Delete', article, :confirm => 'Are you sure?', :method => :delete %>
<% end %>
  </div>

This may be because you don’t have the right javascript files set up. Rails 3 uses unobtrusive javascript to create the DELETE request when you click the link. If the javascript isn’t working, it will fall back to doing a GET which will render the show action.

Make sure you have rails.js and prototype.js in your layout. If you are using a javascript framework other than Prototype, you will need to have that framework (jQuery or whatever) along with the appropriate port of rails.js.
