rails3 before_filter cause Filter chain halted as :authenticate rendered or redirected error

Question

In my index.html, i use <%= render 'rates/rate_form'%> to render the rate form, and the form is ajax.The content of _rate_form is:

   `<%= form_for [@image, Rate.new], :remote=>true do |f| %>  
<input type="hidden" name="image_id" value="<%= @image.id%>"/>
<button type="submit"> Rate</button>
<% end %>`

In my Rates controller, i defined one before_filter, only signed in use can create rate. class RatesController < ApplicationController before_filter :authenticate, :only=> :create

def create
@rate=Rate.new(:rate=>1)

respond_to do |format|
  if @rate.save
    format.html { redirect_to(@rate) }
    format.js 
  end
end
end

in my sesson_helper file:

 def authenticate
   redirect_to signin_url unless signed_in? 
 end

The log is:

Redirected to http://localhost:3000/signin

When i click the Rate button, there is error in console: Filter chain halted as :deny_access rendered or redirected Do you have any idea how to solve it? Thanks a lot!

Answer 1

So you have a filter that runs before every execution of the create action. What it does is that it redirects unconditionally. This effectively means that nobody will ever be able to call the create action. I suppose there should be some check within deny_access that verifies a logged in session, or so.

The Message you see in the logs just informs you that the filter did redirect.
