similar to: undefined method join for STRING error

I can''t imagine what I''m trying to do is complicated at all in Rails. Yet, I am now getting this error: undefined method `state'' for :StudentFailState:Symbol. student.rb has_one :student_fail attr_accessor :student_fail_attribute #controller def student_fail @student = @student.find params[:id] def update_student_fail @student.build_student_fail

Hey all, Let''s say you are not going to use an html form. Rather the user will input data in a third-party application that will communicate with the rails controller through http requests, but serves as a replacement to the html. In other words, it''s taking the place of front end. My question is can you update the attributes of another table, let''s say studentfails

Hey all, I get an undefined method `join'' for #<String NoMethodError. student.rb has_one :student_fail attr_accessor :student_fail_attribute #controller def student_fail @student = @student.find params[:id] def update_student_fail @student.build_student_fail params[:student][:student_fail_attribute] if @student.save #view form_for @student do |f|

I''m looking at code in a project. I have no clue what is being passed into the resource parameter: def read_authorized?(resource) if resource.respond_to? :user_read_authorized? resource.user_read_authorized? current_user else true end end Is there any kind of debugging feature I can run to see what gets passed into resource in this specific

In the example below, what is the dash doing between the class attribute and array: (field_helpers - [:label, :check_box, :radio_button, :fields_for, :hidden_field, :file_field]).each do |selector| -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hey all, This example of working code: @a = @b.where(:a_group_id.ne => nil).collect { |b| b.a_group } doesn''t make too much sense to me. For one, I am not sure what that "ne" is doing there. Is this a postgresql thing? Second, it looks like we are collecting active record objects where the a_group_id is null, collecting them in an array and then invoking the a_group

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

Hey all, I am looking through this example Rails app where a user session is stored in cookie so user signs up in one rails app and navigates to another while still being signed in as unique user. I come across this line of code where I don''t understand where some of these methods are coming from: @session = Session.create!(:user => @user) cookies[:session_token] = {:value

I want to work with both Rails 2 and Rails 3 projects. I have RVM installed. When I upgraded to Rails 3, Installed RVM via terminal: bash < <( curl http://rvm.beginrescueend.com/releases/ … ll-latest) version=$(curl http://rvm.beginrescueend.com/releases/ … sion.txt); mkdir -p ~/.rvm/src/ && cd ~/.rvm/src/ && curl -O http://rvm.beginrescueend.com/releases/ … on}.tar.gz |

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 +

Hey all, I am getting this error: NoMethodError (undefined method `gsub!'' for 2012-01-22 17:00:00 -0500..2012-01-23 00:00:00 -0500:Chronic::Span): in this code: date_range = Chronic.parse(the_date, :guess => false) reports.sum_distance_by_date(date_range).each do |d| u[:m] << d end def

Hey all, I get the following error. Now I know it''s related to a curly brace, but it seems that all curly braces are properly in place. So I''m not sure why I get this error: SyntaxError in DashboardController#panels rails/app/controllers/dashboard_controller.rb:170: syntax error, unexpected ''\n'', expecting tASSOC def panels addDetailToContainer =

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

In the capistrano wiki, it contains this line: set :scm_username, “foo”. If you access your source repository with a different user name than you are logged into your local machine with, Capistrano needs to know. Actually the way I access my repository through my app is through ssh keys. The only user name I have with github is the one I use to log into github to view my repositories. So

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 =

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:

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

"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?
