Hey all, Chronic will parse a date range in console: Chronic.parse(1/1/2011 - 1/1/2012, :guess => false) => 2012-01-01 12:00:00 -0500..2012-01-01 12:00:01 -0500 However, when I use logger to check if it''s parsing in application, it is not: logger.info "The value of history date is #{history_date}" => The value of history date is 1/1/2011 - 1/1/2012

In console, I run the following and any? returns true: drivers = Driver.select("drivers.*, drivers.id").joins([:reports, :driving_habits]).where("extract(MONTH FROM reports.time) = ? AND extract(YEAR FROM reports.time) = ?", 3, 2013).uniq.order("drivers.id asc").page(2).per(1) drivers.any? => true This correctly evaluates to true because the relation contains one

"Object is the root of Ruby''s class hierarchy. Its methods are available to all classes unless explicitly overridden." Wouldn''t Class class be at the root of the class hierarchy? After all, look at this: 1.9.2p290 :006 > Object.instance_of? Class => true Object is an instance of class, after all we can use one of Class'' instance methods on Object:

I''m looking at the documentation: http://ruby-doc.org/stdlib-2.0/libdoc/net/http/rdoc/Net/HTTP.html And I notice two uses of Net::HTTP. Both are using GET requests. But what''s the difference? When to use which? Net::HTTP.start(uri.host, uri.port) do |http| request = Net::HTTP::Get.new uri response = http.request request # Net::HTTPResponse object end uri =

The % is modulus (remainder) operator and ^ is bitwise. In this context, we take a file, and go through each character and encrypt it. But why are the ^ and % operators used here: def encrypt(reader, writer) key_index = 0 while not reader.eof? clear_char = reader.getc encrypted_char = clear_char ^ @key[key_index] writer.putc(encrypted_char) key_index = (key_index +

when you add a gem to the Gemfile and then run bundle install, where does the command look for the gem? If you had "gem ''rails'', :git => ''github.com/rails/rails.git", I assume it would update your system .rvm gems directory with the latest github commits. But what is the default repository that bundler looks for gems? -- You received this message because

>> reload! Reloading... => true >> puts Class < Module true => nil >> puts Module < Class false => nil >> puts Module < Object true => nil >> puts Object < Module false => nil >> Object.parent => Object The above indicates that the Class object instance inherits from the Module object instance and the Module object instance

I''m careful to create separate gemsets for each project, so when I run bundle install, it only installs gems for that gemset. This way gems dont creep into the wrong projects. Now I just pulled a project from github. I made sure I was in the correct gemset, and then I run bundle install and it works fine. but then when I use rake to create the database "rake db:create". I get

append_features(mod) The documentation says: When this module is included in another, Ruby calls append_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to add the constants, methods, and module variables of this module to mod if this module has not already been added to mod or one of its ancestors. See also Module#include. What if this module is

Rails extends Ruby with mattr_accessor (Module accessor). As Ruby''s attr_accessor generates getter/setter methods for instances, mattr_accessor provide getter/setter methods at the module level. In below example, you see that mattr_accessor declared in the class context of LookupContext. It''s declared in class, not module. However, modules are defined in LookupContext, for

There''s a number of calls in the Rails source to convert_to_model, which takes an activerecord object instance: convert_to_model(object) Here''s the thing. All convert_to_model does is calls to_model, which returns self (the ActiveModel instance). Am I missing something here? Why call a method that returns the same thing? @user => #<User id: 3, name:

For example, you see files called rails/actionpack/lib/action_controller/base.rb which adds methods and such to the open module ActionController. What scope is ActionController in? Is it just called the global scope? Obviously, there is namespace resolution lookup. And a good example of this is in the Base class of the same file. It references one module like this: AbstractController::Layouts
