问题 I am seeing a conflict between what Rails 3.1 guides suggest, and what Google PageSpeed suggest for managing of cached assets. Rails 3.1 guides for asset pipeline offer a solution Apache server configuration here The salient bit of apache config is: <LocationMatch "^/assets/.*$"> # Some browsers still send conditional-GET requests if there's a # Last-Modified header or an ETag header even if they haven't # reached the expiry date sent in the Expires header. Header unset Last-Modified Header

问题 We are going to use mysql 5.5 in our application for production. I did some online search and it seems that mysql2 0.2.6 is the one for mysql5.5. Is this gem good for windows as well? Any tips on how to install and manage for production? Thanks. 回答1: The gems (either mysql or mysql2) provides an version-independent layer to the version of MySQL you are running. However, if you're using a pre-compiled gem, it will require a version specific MySQL library be installed in your system. To avoid

问题 Because a jQuery plugin I use in my application has direct references to images, I'm trying to turn off asset fingerprinting. So I set config.assets.digest = false in my production.rb, but now none of my image references work at all. /assets/foo.png just returns a blank response. I really don't want to alter the jQuery plugin's code and add erb image helpers, but I'm not sure what else to do. And frankly, the asset fingerprinting for images seems to be much more trouble than it's worth. Does

问题 I'm building an index page where I need to display results which have a date, ordered chronologically (from the earliest date to the newest one), but I need to always show the last page by default. I can't use a DESC order for the date because it would defeat the whole purpose of what I need this for =(. TL;DR: I need to show a paginated log list, sorted by date ascending, but starting in the last page. Is this possible with will_paginate? Thanks! 回答1: You can build your query, get the total

问题 I'm trying to get a url using open-uri. my code is outrageously simple url = open("http://localhost:3000/descriptions") return render :text => url.to_json When I run this code, I get a timeout error. When I request just "http://localhost:3000", I get my home page (which is correct). So it seems this is breaking on the path somewhere. I've tried using net-http with uri (not sure if that would make a difference) and I still have the same issue. I want to get a path and a query, but I can't seem

问题 I added the this line load 'deploy/assets' to my Capfile to deploy assets with Rails 3.1. Capistrano gets to this line * executing "cd /home/deploy/armonia/stage/releases/20110928021521 && bundle exec rake RAILS_ENV=stage RAILS_GROUPS=assets assets:precompile" then fails with Could not find multi_json-1.0.3 in any of the sources which is weird because the gem is found when I run bundle show multi_json on my deployment server. What causes this? 回答1: Fixed this by updating to bundler to 1.0.18,

问题 Rails 3.1 and Devise 1.5 question. I'm using the following code to display flash messages in my layout: <% flash.each do |key, message| %> <%= content_tag(:div, message, :class => "flash #{key}") %> <% end %> I'd like to change the css class for some of my confirmation messages from notice to success, but I don't know where to override or change the key because I don't know where it's set. Can anybody point me in the right direction? Thanks! 回答1: So the way to do this is to edit the devise
