Ruby delete method does not work

For my blog, the delete method doesn't work (edit, update, create... are fine).

I already tried different ways of defining the link, but it all didn't help yet. Now at the moment, my html.erb code looks like the following:

<div class="btn">
<%= link_to "Delete", post_path(@post), :confirm => "Are you sure?", :method => :delete %>
</div>

And the controller like this:

def destroy
    @post.destroy
    redirect_to post_path
end

Rake routes:

                    posts GET    /posts(.:format)                    posts#index
                          POST   /posts(.:format)                    posts#create
                 new_post GET    /posts/new(.:format)                posts#new
                edit_post GET    /posts/:id/edit(.:format)           posts#edit
                     post GET    /posts/:id(.:format)                posts#show
                          PATCH  /posts/:id(.:format)                posts#update
                          PUT    /posts/:id(.:format)                posts#update
                          DELETE /posts/:id(.:format)                posts#destroy

Please try adding a mechanism to find the @post since http is stateless @post needs to be assigned. @post = Post.find(params[:id]) part has been added for you to try. Thank you.

def destroy
  @post = Post.find(params[:id])
  @post.destroy
  redirect_to posts_path
end

If the routes are resourceful and the delete is happening in the DB, the problem is probably that the redirect_to route is not plural.

see: http://guides.rubyonrails.org/routing.html#path-and-url-helpers

Corrected:

def destroy
  @post.destroy
  redirect_to posts_path
end

try this query for the link:

<div class="btn">
<%= link_to "Delete", @post, :confirm => "Are you sure?", :method => :delete %>
</div>

I think the problem just lies on the post_path(@post). Hope that this works.
