Rails Update to 3.2.11 breaks running multiple servers

由 风流意气都作罢 提交于 2019-11-26 20:57:55
问题 Our application runs two Rails servers at different ports that talk to each other. Using Rails 3.2.8, I could open a terminal, cd to the project, run rails s -p3000 , open another terminal, run rails s -p3001 and everything worked fine. The gemfile contains thin , so thin would be launched automatically, but using the rails s would allow using the --debugger when needed. Since updating the Rails 3.2.11 this no longer works. I get an error: "A server is already running. Check /home/george

No secret option provided to Rack::Session::Cookie warning?

I am running Rails 3.2.3, Ruby 1.9 under Fedora 17. I get this warning, when I run rails s , and how do I fix? SECURITY WARNING: No secret option provided to Rack::Session::Cookie. This poses a security threat. It is strongly recommended that you provide a secret to prevent exploits that may be possible from crafted cookies. This will not be supported in future versions of Rack, and future versions will even invalidate your existing user cookies.

问题 Seems the last post for this problem was closed for one reason or another so I'll try my luck... I'm trying to run a simple "rake db:migrate" command. When I do, I get the error in the title. Yes, the solution "appears" obvious but it's not because I don't my Rakefile does not contain any references to 'rake/rdoctask'. It seems to be coming from documentation.rake but when I try to change that file as recommended by the error, I get a different error. I have found a couple of posts declaring

Rails database defaults and model validation for boolean fields

由 孤街浪徒 提交于 2019-11-26 16:59:56
问题 In a Rails model I have an attribute is_subscriber , when I constructed a db migration to add this column to the database I specified the default value to be false: t.boolean "is_subscriber", :default => false I also specified in the model that this attribute needs to be present: validates :is_subscriber, presence: true So why do I get this error when I create a model instance without specifying this attribute? 2012-05-08T21:05:54+00:00 app[web.1]: ActiveRecord::RecordInvalid (Validation

Using Rails link_to for links that post

由 纵饮孤独 提交于 2019-11-26 15:39:22
问题 I have a link that I need to submit a post request with. Normally, I'd use jQuery and prevent the link's default behavior and then submit a form to the destination. This seems like something Rails should be able to help me out with. Sure enough, the link_to method has an option for specifying a POST http method: link_to "Profile", 'http://example.com/profile', method: :post That works, but I need to add 2 parameters too. I tried: link_to "Profile", 'http://example.com/profile', method: post,

由 那年仲夏 提交于 2019-11-26 11:28:17
问题 I need some informations for the best practices in Ruby on Rails, especially with Controller who have to do a lot of things , so, a simple \"show\" action is now up to lines. I know, it\'s not really good, and I have specific code in it. Here is a sample code: def show sound = Sound.find(params[:id]) @xml_path = File.dirname(sound.file.path) s3 = AWS::S3.new( :access_key_id => \'XXX\', :secret_access_key => \'XXX\') @url = s3.buckets[\'dev\'].objects[sound.file.path[1..-1]].url_for(:read,
