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:

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:

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 +

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 =

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

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

>> 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 have a Project that has_many Tasks. Tasks belongs to a Project. When I try the following: project = Project.new project.tasks.build I get: >> s = Project.new => #<Project:0x25f9e28 @attributes={"name"=>"", "end_at"=>nil, "updated_at"=>nil, "published_at"=>nil, "user_id"=>nil,

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

Hey all, I created a seed task: def books! books = Book.where(:type_id => Type.find_by_name(''Fiction'')).order(''id'') books.each do |book| @books = 4.times.map do |i| subbook! "#{book.book_num}-#{i}".to_s, :book_state => BookState[:available].id, :book => book end end puts "log it:

Hello It seems that datetime_select, is creating an instance of the Time class. Why would that be? I found this while building a site where people can create vigils (prayer vigils, peace vigils, etc). When I added a validation method that compared start_date to created_at, it generated the error: ArgumentError (comparison of Time with DateTime failed): I was able to put a breakpoint in the

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

Hello all, Can someone help me with this query ? Here is the query used in rails 2. The idea here is to obtain the top 10 widgets.
