问题 I have spent hours upon days trying to resolve this. Rake is throwing the following error: dcarpenter$ rake rake aborted! uninitialized constant ActionView::Helpers::JavaScriptProxy I can't seem to find anyone who has had this issue on Google, this site or elsewhere. What steps should I take to resolve this and what do I need to know? rake --trace yields: /Users/dcarpenter/Dropbox/workspace/gems/rake-0.9.2/lib/rake/ext/module.rb:36:in `const_missing' /Users/dcarpenter/Dropbox/workspace/gems

问题 I have the following code in my controller def create @severity = Severity.new(params[:severity]) if @severity.save flash[:notice] = "Successfully created severity" render 'save' end end I am trying to get the method to render another view file other than create.js.erb however the controller always renders the default rather than the save.js.erb.

问题 I'm currently trying to write an add friends step to our registration system, and I've been asked to implement something similar to the way foursquare works. It pulls down your friends from Facebook, checks to see if any of them are already on the foursquare site, and then asks if you want to connect with them. What is the best way to go about implementing this kind of functionality? I have seen examples with the FB JS SDK, however I would prefer a more integrated approach. Thanks Adam 回答1:

问题 I am using Ruby on Rails 3 and I would like to send 'email' and 'password' values (I know, I should not, but I need that) over the HTTP protocol. I need to send user credentials from a my client application to a my service application*. I can use a public a private RSA key to accomplish that but, if so, I must don't send the public key to the recipient over HTTP, otherwise an hacker can steal the key and decrypt contents.

问题 I have been trying to get my dev environment setup on OS X for a couple of days now, and I have had a lot of trouble with mysql. I have installed mysql via the dmg file available from the mysql website. This fixed most of the trouble I was having. My current problem is that, when I run "rake db:migrate" I get the following error: rake aborted! undefined method `init' for Mysql:Class I read somewhere that using gem 'mysql2' in the Gemfile and mysql2 as the database adapter might fix the

Ideally, when the form is submitted, a rating will either be created or updated. Elsewhere, I have that an article has_many ratings.
