ruby-on-rails-3.1

问题 Using Rails 3.1.3 with Ruby 1.9.3p0. I've discovered that by default, Rails does not use sentence case for form buttons. For example, instead of an "Update user" button, it generates an "Update User" button. The button names come from the ActionView locale file. Is there a way to create a default that downcases the model name? This is not covered in the Ruby on Rails Guides i18n section on Interpolation so maybe it is not possible. The following doesn't work: en: helpers: submit: update:

问题 I have a staging and a production environment on my rails 3.1rc6 app which uses subdomains. I've bought and configured different domain names for these environments, because the default something-something.herokuapp.com doesn't play nicely with subdomains. When I set session_store.rb to this for one environment, everything works fine: AppName::Application.config.session_store :cookie_store, :key => '_sample_app_session' , :domain => '.mystagingdomain.co.uk' But I can't seem to add in a

问题 I realize it's been pulled into a separate gem, but what's the reason? Is this just a matter of streamlining Rails, or is there some reason I should be weary of auto_link? (The gem says it's meant to 'bridge the gap for people migrating', which suggests to me that if I'm introducing rails_autolink into a new project, I must be doing something wrong, no?) thanks, 回答1: From the commit where auto_link was removed, Aaron Patterson (tenderlove) explains in the comments: Unfortunately this method

问题 I've just upgraded my app on Heroku from Rails 3.0 to 3.1, and I'm trying to make the assets pipeline work. The main issue is that I can read from the heroku log the following kind of lines, for every asset: 2011-09-03T16:35:28+00:00 app[web.1]: cache: [GET /assets/border-a3c571a354b9381740db48aeebfaa63a.jpg] miss If I understand the pipeline correctly, this should not be "miss" for every request I make from a browser, but it should be found in the cache. Reading the Heroku docs you can find

问题 I'm having a bit of trouble getting my asset pipeline setup working with Heroku/Cedar using Rails 3.1.1 I've pushed my application and it launches successfully but there was no message that said "Preparing asset pipeline" and no static assets are being served up. No JS, CSS, or images are able to be found as there is no slug compilation time or runtime asset compilation being done. Any help would be greatly appreciated. They describe what should happen during deployment at this link which I

问题 I have a plugin-based system that I use for application development in Rails. Each plugin implements an engine with MVC components, etc. The main application is simply an empty harness that delegates all the work to the plugins that are installed. I'm currently upgrading to Rails 3.1 from Rails 2.3.5, and am trying to get the asset pipeline working with my framework. The problem I'm having is trying to programmatically require my plugin's assets into, for example, the application.js manifest.

问题 I'm working on an existing Rails app and am using a localization file, en.yml , to hold most of the app's text. At the moment, we aren't localizing into any other languages, so there's just the one file, but the fact that we're putting translate('some.key') into our views means that adding another language will be as simple as adding another file - say, sp.yml The problem is, en.yml has grown to the point that I doubt all the keys are being used. Apart from git grepping for translate calls

问题 Is there some way to add the defer attribute easily using the javascript_include_tag helper in Rails? I.e., is there some easy way to turn <%= javascript_include_tag "blah.js" %> into <script defer src="blah.js"></script> 回答1: <%= javascript_include_tag "blah.js", :defer => "defer" %> This will get you (in development): <script defer="defer" src="/assets/blah.js" type="text/javascript"></script> 回答2: You can also do <%= javascript_include_tag "blah.js", defer: true %> which is more consistent

问题 I've been trying to use Rails and when I use rake, I get this error. Any suggestions on which run time should I use? ngzhongqin@ngzhongqin-linux:~/RailsProjects/webuiltit$ rake db:create:all --trace rake aborted! Could not find a JavaScript runtime.
