Hi, Is there any performance difference between rendering partials vs. calling a helper? When we initally started coding we built a bunch of small partials and if there is a significant performance overhead with them, we''ll probably try to switch them over to helpers. They seem like they would be quite similar but I don''t know the full details of how partials are handled.

Hi, I am trying to do fragment caching using :mem_cache_store. However, when I compare it to fragment caching using :file_store, it seems to be a lot slower. Here are the results: uncache Completed in 2.20246 (0 reqs/sec) | Rendering: 2.19891 (99%) | DB: 0.00017(0%) | 200 OK [ http://127.0.0.1/] using file_store Completed in 0.00952 (105 reqs/sec) | Rendering: 0.00702 (73%) | DB: 0.00000(0%)

I dont'' understand why it''s not possible to have a conditional redirection in rendering respond_to do |format| format.js { render :update do |page| page.redirect_to posts_url if @located page.replace_html ''error_message'', "Error..." page << "$(''popup_error'').popup.show();"

I''m running on a brand new MacBook Pro with a relatively clean working set. using Mongrel in production mode on port 3000. The home page does not hit the database and I''m getting: Processing HomeController#index (for 127.0.0.1 at 2006-06-29 14:59:02) [GET] Session ID: e11f7df52bffff304ca7c88e672ef71a Parameters: {"action"=>"index",

My code is something like this. class FirstController < ApplicationController def foo #some processing render (:controller => ''second'', :action => ''index'') end end I tried using both render and redirect but it seems it''s not possible to send the control from within a controller to some other controller. Am I missing something

I just spent a few hours tracking down a bug in Rails 1.1, so I thought I''d post the issue and a workaround just in case anyone else hits it. I designed a security enhancement so that controller methods can be protected by preceding them with a role. The standard Ruby method_added() callback is used to detect when controller methods are added, and then I manipulate the

Hi all, Starting out with load testing for one of my rails apps and am pretty confused about what the ''best'' way to do this is. I read the tuning article at http://mongrel.rubyforge.org/docs/how_many_mongrels.html but am getting some weird numbers from the tests recommended at the bottom: httperf --server www.theserver.com --port 80 --uri /tested --num-conns <10 second

Filter chaining appears to behave in differently than Rails 1.2.x. It seems that I''m getting a lot of errors along the lines of: ActionController::ActionControllerError: filter #<ActionController::Filters::ClassMethods::BeforeFilterProxy:0x322f468 @filter=#<ActionController::Filters::ClassMethods::SymbolFilter: 0x322f4b8 @filter=:login_required>> was in the wrong place!

The view file (eg. apps/views/items/list.rhrml) is still displayed even when the action is hidden (hide_action :list). How can I hide view file form being automatically displayed in this circumstance? thanks, jigar -- Posted via http://www.ruby-forum.com/.

I have a common failure page that I may need to render to upon failing some test that occurs in an after_filter method. I''d like to use the after_filter to take over the control of the rendering, like so: def test_for_validity some_boolean = my_test return render(:action => ''disqualified'') unless some_boolean @success_controller ||= controller_name

Hi, I''m trying to serve the iPhone a video file from my controller using send_file. However, it appears as thought the iPhone requires byte- range request support and rails doesn''t seem to support this. If I give the iPhone a url that points to an actual file (i.e. it''s served by my webserver nginx, instead of rails) it downloads and plays it fine. Here is the proof

This week we have started one new project with Ruby on Rails as primary framework. My first task was to prepare runtime environment for it on one of our development servers. When I have tried to research how people doing it, I noted that there is no information about how to deploy rails application with nginx as frontend and what is performance of such solution. Before blindly make any

Hi All, I can''t seem to render a template outside of a controller in my Rails 3 application. The googling I''ve done has been helpful, and I eventually found some useful info at http://www.swombat.com/rails-rendering-templates-outside-of-a-contro. However, this seems to be broken in Rails 3. Does anyone have any ideas how I can fix this method or perhaps know of a better

I am having trouble rendering a partial called ''names'' through a submit tag located within that partial. The form data is saving with my current code. However, the existing data is not loading into the form and the partial is not being re-rendered upon submission to reveal the changes to this data.What might I do to fix this? show.rhtml <%= javascript_include_tag :defaults

Hey guys, I am developing an application for my university and I''m having problems with the way it''s getting rendered. I configured the main controller to use a layout called "unet-main" and when it displays on my local machine it works great, but when I upload it to my dedicated server and try to view it the layout repeat itself three times downwards. My dedicated

Hello, I have a number of legacy 3D and 2D rendering applications (essentially batch applications) written in C++ that I now want to expose as services on the Web. For example as a Facebook photo hacking widget. Can someone please suggest a pattern I should follow as the Rails wrapper around my code. One of the issue is not having the app. block on long running pixel crunching. Cheers, Doug

Hey all Im working on improving the speed of my application. Ive taken on board everything that has been said on this forum so far, im using httperf to benchmark and try to improve performance. However, I have some question marks over how best to go about improving performance in certain areas.... With no caching or such like deployed the application runs at an rather slow 35 - 38 req/s. A

I found through the log file that the render of the rhtml template would take too much time if there exists ruby code in the rhtml files.In many cases,these ruby code are tied with these rhtml files closely and can not be decoupled from that,therefore,i have a question that,is there exist some way to improve the rendering speed of rhtml when some ruby codes are included? -- Posted via

Hey all, I am writing a plugin in which I want to stop the rendering of an action with an unauthorized response if the user is not authorized to view the resource. I am using a before filter to achieve this and inside that before filter I do it like so: render :text => "Unauthorized!", :status => :unauthorized, :layout => false The status is properly set since I see the

We are running Apache and Mongrel on RHEL4 and have been experiencing some interesting behaivor. Sometimes when someone logs into our application (it uses the acts_as_authencticaed and acl_system2) the following happens. Instead of the browser rendering the html and displaying all the form elements corretly as you would expect, it simple spews back the output without attempting to render. So
