By default, Rails will add an inflections.rb to config/initializers . There you can add: ActiveSupport::Inflector.inflections do |inflect| inflect.irregular "is", "are" end You will then be able to use pluralize(@total_users, "is") to

由 社会主义新天地 提交于 2019-11-29 10:35:06
I am using RubyMine with rails 3.2.12 and I am getting following deprecated warning in my IDE. Any Idea How can I solve this deprecated warning? find(:first) and find(:all) are deprecated in favour of first and all methods. Support will be removed from rails 3.2. I changed my answer after @keithepley comment #Post.find(:all, :conditions => { :approved => true }) Post.where(:approved => true).all #Post.find(:first, :conditions => { :approved => true }) Post.where(:approved => true).first or post = Post.first or post = Post.first! or post = Post.last or post = Post.last!

Asset pipeline, compass font-face and eot?iefix call to the font

由 非 Y 不嫁゛ 提交于 2019-11-29 09:59:30
问题 I am trying to use a Compass font-face mixin, which contains the inclusion of *.eot?iefix My app/assets/fonts contains all the font types needed, including .eot. When I try to run assets:precompile the task fails saying something like: webfont.eot?iefix isn't precompiled Do you know the possible solution for this problem? It runs with no error in case I have config.assets.compile = true, but as I've understood it's better not to use it on production. 回答1: You can do it with pure Scss too:

asset_path in scss file rails

由 我的梦境 提交于 2019-11-29 09:15:25
I am having issues with asset_path in production. Rails 3.1.1 #config/environments/development.rb Scc::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable

Assets not being run though the .erb preprocessor

由 纵饮孤独 提交于 2019-11-29 08:21:54
I am having trouble trying to rake assets:precompile in my rails 3.1 app. I keep getting the following error: rake aborted! Invalid CSS after "...und-image: url(": expected ")", was "<%= asset_path(..." It seems that the erb preprocessor is not being invokeb but my file is called style.css.scss.erb . Any suggestions? Ruby documentation seems a bit unclear on a few things such as the usage of the asset_path and other such helper in stylesheets. Anyways this is what I did to get around the exact same problem: I decided to do this the SASS-way by changing my stylesheet extensions from css to scss
