#5310 ✓invalid

problem with renderiong

Reported by setsunaruu | August 5th, 2010 @ 07:30 PM

I'm create scaffold for table people, than i remove action show like this
# POST /people # POST /people.xml def create

@person =[:person])

respond_to do |format|
    format.html { redirect_to :action => 'index' }
    format.xml  { render :xml => @person, :status => :created, :location => @person }
    format.html { render :action => "new" }
    format.xml  { render :xml => @person.errors, :status => :unprocessable_entity }


# PUT /people/1 # PUT /people/1.xml def update

@person = Person.find(params[:id])

respond_to do |format|
  if @person.datum.update_attributes(params[:datum]) && @person.update_attributes(params[:person])
    format.html { redirect_to :action => 'index' }
    format.xml  { head :ok }
    format.html { render :action => "edit" }
    format.xml  { render :xml => @person.errors, :status => :unprocessable_entity }


I create a new person on page 'new', then redirect to 'index' (on development)
When I run it into production (mongrel_rails + lighttpd) I'm going to go on blank page.

In log file this look like

    I had a similar issue where a HTTP POST (create or update action) didn't render the requested page. Within the log file I also didn't see a render request for /people (or whatever) after a create or update action. When I used Firebug I saw the HTTP POST returned a 404 response containing the message You are being <a href="http://site/people">redirected</a>. The client never asked the server to render /people because of the 404 response. Thats why the render request never showed up in the log file.

    I my case it turned out to be a proxy problem, somehow changing the 302 response into a 404. So my suggestion would be to check if there's a proxy in between which causes this error.

    Are you still experiencing this issue?

    • State changed from “new” to “invalid”
    • Importance changed from “” to “Low”

    Is the log provided above hand-written cos i can see a parameter "deatt h(2i)" which would lead me to believe that you had a failure in your application, perhaps.

    This is a very standard and tested functionality of Rails and the problem is more than likely in your local setup. I suggest you use Harm-Jan Blok's suggestion and use Firebug to detect actual return codes and debug intermediate proxies or such like.

    I would also suggest you run the same code in your development machine but with RAILS_ENV set to production to see if you get the same error. Also try to see if you get the problem with production settings with mongrel only or with webrick or thin?

    Marking the ticket invalid but if you do come across a scenario where there is indeed a Rails problem, we can re-open this ticket. Please provide a failing test and/or a patch in that case.
