activesupport

问题 I have a rails (v5.1) project in development, in which I recently installed Sidekiq. I now have an autoload issue, getting the subject argument error. I have done a fair bit of research which seem to boil down to this being a problem of "trying to access an automatically reloaded class (in app directory) from one that is not automatically reloaded (in lib directory)," and that when the code is reloaded, Rails throws an error since the module from which the constant search is starting shouldn

问题 Where and when does OpenSSL::OPENSSL_VERSION_NUMBER get set? And why isn't it getting set to the latest OpenSSL that I've just installed? First the error(s): $ gem install activesupport -v '3.2.13' Error while executing gem ... (RuntimeError) Unsupported digest algorithm (SHA512) If I go directly into irb, I can see that Ruby is using the "old" openssl: $ irb >> require 'openssl' => true >> OpenSSL::Digest.new('sha512') RuntimeError: Unsupported digest algorithm (sha512) >> OpenSSL::OPENSSL

问题 I have a default time zone setup for the rails application. And an instance of the Date object. How can I get make Date#beginning_of_day to return the beginning of the day in the specified time zone, but not my local timezone. Is there any other method to get beginning of the day time in the specified timezone for the given date? date = Date.new(2014,10,29) zone = ActiveSupport::TimeZone.new('CET') date.foo(zone) # should return "Wed, 29 Oct 2014 00:00:00 CET +01:00" zone = ActiveSupport:

问题 I'm trying to make all Hashes in my program be ActiveSupport::OrderedHash. I can override the Hash.new constructor by ::Hash = ActiveSupport::OrderedHash but {}.class is still hash. def {} gives me a syntax error. It was recommended that this is a duplicate of this question, but I don't think that is the case. My question isn't about subclassing Hash, it's about overwriting the default { } => Hash constructor. 回答1: Hash literal {} is hard-coded in Ruby, and you cannot change it. {} will

问题 I tried using ActiveResource to parse a web service that was more like a HTML document and I kept getting a 404 error. Do I need to use an XML parser for this task instead of ActiveResource? My guess is that ActiveResource is only useful if you are consuming data from another Rails app and the XML data is easily translatable to a Rails model. For example, if the web service is more wide-ranging XML like a HTML document or an RSS feed, you want to use a parser like hpricot or nokogiri. Is this
