similar to: Page Caching... extending it???

Is it possible to take advantage of http caching/proxy caching with dynamic pages? i.e. pages with section/part that can change over time but certain part of the page remain the same. I would rather not keep re-rendering the static part but insure the dynamic part are rendered with fresh data. I am using memcached mostly as an object store that I can minimize db hits but I still am rendering a

Hi, I''m working on a website that has a very slow loading frontpage. I wanted to start by caching certain elements that have high load. For example, it loads the last 50 comments, along with the corresponding usernames, avatars and more. So I cached that fragment and created a sweeper that observes Comment and expires after every create or destroy action. However, I have two problems:

Hey guys, As most of you know, Rails 3.1 introduces query caching for ActiveRecord. Great change all-in-all, but for those of us with IT department mandates for using MySQL (yeah, yeah, I know...), it''s kind of a mixed bag. I need to disable query caching in a project I''m building based on 3.1. I''ve tried a couple different approaches, both without any success. I

What is the best way to set up caching when GET parameters are involved? For example I don''t want both /index and /index? tags=example to be cached as index.html. Does that make sense?

Hi, I am not sure how to extend Rails. I want to write a class where I can Access my Models, like "User.all".

I am using memcache for caching in my rails app and currently I have a dev and a production environment. I would like to run the dev environment without caching so that I can debug more easily but I wanna enable the caching in production obviously. I am using github and capistrano for deployment. Without doing a check at every statement where I can potentially dig into the cache, is there any

Hi all, I would like to use page caching on my homepage, but also want to enable people to sign in via a modal dialog sign in form. I could have a setup in which when a user lands on the cached homepage, an Ajax GET request pulls in the whole login form so that there is a fresh authenticity token. That said, besides the additional hit to the server, the CSRF token in the head area of the page

What''s the best way to handle views that show the top 10/most popular/ Recently updated/most commented type listing? Should I have a separate model that is populated with records from other models by a background job or should I need to use some sort of caching? Perhaps both?

Hello. I''ve read about examples on inheritance with rails. Here is an example: http://juixe.com/techknow/index.php/2006/06/03/rails-single-table-inheritance/ The way is to add a type field in the table. So if I have an Animal class with an attribute name, I can inherit from this class like: Dog < Animal, Cat < Animal, and so on. With the type field in the table I can do Dog.all,

My understanding is that: 1. rails is single threaded and serves one request at a time 2. mongrel is single threaded and can process one rails request at a time 3. mongrel_cluster starts a few mongrel servers on the same machine Based on this, the single most important factor becomes the time it takes to load a single page (to avoid blocking). If this is all true, what''s considered a

Hi I''m trying to create a web application with a UI that is fundamentally similar to Google Reader, in Rails 3 and probably with some Javascript toolkit (jQuery?). I''m new to web development (my background is in desktop application development), however, and after some experimentation with CSS layout I''m frankly unsure of how to achieve the desired layout. Therefore

Hey folks, I like what I''m reading about improved performance via Service Oriented Architecture for my Rails app. Stepping in that direction will require some code reorganization, though. Has anyone regretted the time invested in Rails SOA or suffered any other drawbacks that might -- from a business perspective -- have disinclined them from going SOA? Lille -- You received this
