• How to unit test internals (organization) of a data structure?

  - by Herms

  I've started working on a little ruby project that will have sample implementations of a number of different data structures and algorithms. Right now it's just for me to refresh on stuff I haven't done for a while, but I'm hoping to have it set up kind of like Ruby Koans, with a bunch of unit tests written for the data structures but the implementations empty (with full implementations in another branch). It could then be used as a nice learning tool or code kata. However, I'm having trouble coming up with a good way to write the tests. I can't just test the public behavior as that won't necessarily tell me about the implementation, and that's kind of important here. For example, the public interfaces of a normal BST and a Red-Black tree would be the same, but the RB Tree has very specific data organization requirements. How would I test that?

• Linux standard input issue

  - by George2

  Hello everyone, I am new to Linux. And I am using Red Hat Enterprise Version 5. There is a ruby program which use standard input as its input (e.g. the Ruby program process input from standard input). I think standard input should be keyboard, correct? So, I think other kinds of input (non-standard input) should not work (i.e. the ruby program should not be able to read input from such non-standard input), but actually I have tried using pipe works, I am so confused because I think pipe should be some other kinds of input -- other than standard input, why it could work? i.e. put text "123" in abc.txt with pipe, could achieve the same result as using keyboard as input to type "123" for the ruby program. Here is the sample which works and makes me confused, cat abc.txt | ~/test/rubysrc/foo.rb thanks in advance, George

• ruby tests - error messages don't include line numbers or file name

  - by joshs

  Hi all, How do I get line numbers to be reported with my errors when testing. Here is what I get back on a typical error: josh@josh-laptop:~/d/test$ ruby unit/line_test.rb -n test_update Loaded suite unit/line_test Started E Finished in 0.066663 seconds. 1) Error: test_update(LineTest): NameError: undefined local variable or method `sdf' for #<LineTest:0xb6e61304> 1 tests, 0 assertions, 0 failures, 1 errors It is tough to debug without a line number and filename. From the code samples I've seen, people generally get back a more verbose error reports. How do I enable this? Thanks!

• ruby on rails adding new route

  - by ohana

  i have an RoR application Log, which similar to the book store app, my logs_controller has all default action: index, show, update, create, delete.. now i need to add new action :toCSV, i defined it in logs_controller, and add new route in the config/routes as: map.resources :logs, :collection = { :toCSV = :get }. from irb, i checked the routes and see the new routes added already: rs = ActionController::Routing::Routes puts rs.routes GET /logs/toCSV(.:format)? {:controller="logs", :action="toCSV"} then ran ‘rake routes’ command in shell, it returned: toCSV_logs GET /logs/toCSV(.:format) {:controller="logs", :action="toCSV"} everything seems working. finally in my views code, i added the following: link_to 'Export to CSV', toCSV_logs_path when access it in the brower 'http://localhost:3000/logs/toCSV', it complained: Couldn't find Log with ID=toCSV i checked in script/server, and saw this one: ActiveRecord::RecordNotFound (Couldn't find Log with ID=toCSV): app/controllers/logs_controller.rb:290:in `show' seems when i click that link, it direct it to the action 'show' instead of 'toCSV', thus it took 'toCSV' as an id...anyone know why would this happen? and to fix it? Thanks...

• Problem with returning values from a helper method in Rails

  - by True Soft

  I want to print some objects in a table having 2 rows per object, like this: <tr class="title"> <td>Name</td><td>Price</td> </tr> <tr class="content"> <td>Content</td><td>123</td> </tr> I wrote a helper method in products_helper.rb, based on the answer of this question. def write_products(products) products.map { |product| content_tag :tr, :class => "title" do content_tag :td do link_to h(product.name), product, :title=>product.name end content_tag :td do product.price end end content_tag :tr, :class => "content" do content_tag :td, h(product.content) content_tag :td, product.count end }.join end But this does not work as expected. It only returns the last node - the last <td>123</td> What should I do to make it work?

• Rails best practice on conditional parameters in a controller action

  - by randombits

  I have a controller create action looks for one or more parameters in the following ruleset. Let's say we have two parameters, foo and bar. The rules are the following: 1) if foo doesn't exist in the parameter list, bar must. 2) if bar doesn't exist in the parameter list, foo must. 3) they can both co-exist. they can't both be omitted (that's redundant with my rules above :) ) Can anyone show an example in Rails on how this is handled in the controller? Should I use a before_filter? Would appreciate some guidance as this isn't something that ActiveRecord validates.. so I'd need to build an error message to the user directly from controller logic, not model logic. For bonus points, I output the error in XML, so if you can show how that's done, that'd be great. Hypothetically let's call the resource "Lorem", so it is created via http://foo/lorem.xml and we have lorem_controller.rb.

• Set a script to automatically detect character encoding in a plain-text-file in Python?

  - by Haidon

  I've set up a script that basically does a large-scale find-and-replace on a plain text document. At the moment it works fine with ASCII, UTF-8, and UTF-16 (and possibly others, but I've only tested these three) encoded documents so long as the encoding is specified inside the script (the example code below specifies UTF-16). Is there a way to make the script automatically detect which of these character encodings is being used in the input file and automatically set the character encoding of the output file the same as the encoding used on the input file? findreplace = [ ('term1', 'term2'), ] inF = open(infile,'rb') s=unicode(inF.read(),'utf-16') inF.close() for couple in findreplace: outtext=s.replace(couple[0],couple[1]) s=outtext outF = open(outFile,'wb') outF.write(outtext.encode('utf-16')) outF.close() Thanks!

• Python - converting wide-char strings from a binary file to Python unicode strings...

  - by Mikesname

  It's been a long day and I'm a bit stumped. I'm reading a binary file that contains lots of wide-char strings and I want to dump these out as Python unicode strings. (To unpack the non-string data I'm using the struct module, but I don't how to do the same with the strings.) For example, reading the word "Series": myfile = open("test.lei", "rb") myfile.seek(44) data = myfile.read(12) # data is now 'S\x00e\x00r\x00i\x00e\x00s\x00' How can I encode that raw wide-char data as a Python string? Edit: I'm using Python 2.6

• Remove unncessary error raised by paperclip - filename is not recognized by the 'identify' command.

  - by kgpdeveloper

  I've been searching on how to solve this issue but could not find any real and working solution. User model: validates_attachment_content_type :avatar, :content_type = ['image/jpeg', 'image/pjpeg', 'image/x-png', 'image/png', 'image/gif'] Unnecessary error shows up when invalid file type is uploaded: Avatar /tmp/sample,23283,0.txt is not recognized by the 'identify' command. Server details: Ubuntu and Debian which identify results to /usr/bin/identify Specifying command path does not solve the issue: Paperclip.options[:command_path] = "/usr/bin" Any ideas? I looked at geometry.rb file and there seems to be something wrong with it. def self.from_file file file = file.path if file.respond_to? "path" geometry = begin Paperclip.run("identify", %Q[-format "%wx%h" "#{file}"[0]]) rescue PaperclipCommandLineError "" end parse(geometry) || raise(NotIdentifiedByImageMagickError.new("#{file} is not recognized by the 'identify' command.")) end Let me know if anyone has solved the same issue and how. Many thanks.

• Problem w/ Paperclip, MacPorts, ImageMagick & Snow Leopard

  - by Kyle Decot

  I'm attempting to use ImageMagick along w/ Paperclip to handle the images on my rails app. The problem is whenever I try to upload an image I get the following in the terminal: [paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /var/folders/go/goZ833AaFaqyvv5RnLqQmE+++TM/-Tmp-/stream20110107-6356-1xfs9j1-0.jpg is not recognized by the 'identify' command.> I have added the following to my environments/development.rb file: Paperclip.options[:command_path] = "/usr/local/bin" If I try to interact w/ ImageMagick in the terminal by using "convert" or something similar I get: dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib Referenced from: /usr/local/bin/convert Reason: Incompatible library version: convert requires version 10.0.0 or later, but libltdl.7.dylib provides version 9.0.0 Trace/BPT trap I've already tried updating everything w/ port but the problem still persists. Does anyone have any ideas or suggestions?

• Auto update CSS from SASS/SCSS in Rails?

  - by Vulgrin

  Maybe I'm confused on how SASS/SCSS works within Rails (2.3.8.) but I was under the impression that if I included the option Sass::Plugin.options[:always_update] = true that whenever I changed my SCSS file and then hit the page (controller) again, the SCSS would recompile. I can't seem to get this to work, and can't seem to find a good tutorial / example for it. I've tried setting the above property in the Environment.rb file, but it didn't seem to do anything. I tried putting it in its own initializer with require 'sass' but that doesn't seem to work either. What am I missing? Or am i just forced to keep a terminal open with a sass --watch command running to be able to rapidly debug / change my styles? thx

• How to read a file byte by byte in Python and how to print a bytelist as a binary?

  - by zaplec

  Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks. EDIT: Also I collect those bytes in a list and I would like to print them so that they don't print out as ASCII characters, but as raw bytes i.e. when I print that bytelist it gives the result as ['10010101', '00011100', .... ]

• I want multipart/alternative; ActionMailer only sending text/html

  - by macek

  I'm following the Ruby on Rails Guide: ActionMailer Basics Section 2.7 Snippet: Action Mailer will automatically send multipart emails if you have different templates for the same action. So, for our UserMailer example, if you have welcome_email.text.plain.erb and welcome_email.text.html.erb in app/views/user_mailer, Action Mailer will automatically send a multipart email with the HTML and text versions setup as different parts. Well, I have both: app/views/user_mailer/welcome_mail.text.html.erb app/views/user_mailer/welcome_mail.text.plain.erb app/models/user_mailer.rb class UserMailer < ActionMailer::Base def welcome_mail(user) recipients user.email from "[email protected]" subject "Thanks for registering" body :user => user end end Any luck?

• Partial form with nested routes

  - by jerhinesmith

  I have two models -- User and Entry -- that are related through a has_many relationship (a User has many Entries). I'm using RESTful routing, and have the following in my routes.rb file: map.resource :user, :controller => "users" do |user| user.resources :entries end This seems to work, but in my partial _form file, when I do this: form_for [@current_user, @entry] do |f| # Form stuff end It generates a URL like this: /user/entries.%23%3Cuser:0xb6a6aea8%3E instead of /user/entries Am I missing something? I should note that the correct classes are applied to the form when doing creation vs. editing, so it does seem to be correctly interpreting what I'm trying to do -- it's just that I can't submit the form to an invalid url.

• Devise email confirmation from localhost

• Rails Model multiple column uniqueness

  - by Jty.tan

  I am making a Viewer model with belongs_to :users belongs_to :orders that joins the models Users and Orders with a :has_many :through => :viewers. And the Viewer model has the attributes of user_id and order_id. How would I set it up so that new viewers are only accepted if both user_id and order_id are unique in the same row? I remember in MySQL being able to do so with a flag (although I can't for the life of me remember what it was), but I'm not sure how to do it with Rails. Can I do something like (for Viewer.rb) validates_uniqueness_of :user_id, :scope => :order_id?

• Manipulating binary data in Python

  - by Dominic Bou-Samra

  I am opening up a binary file like so: file = open("test/test.x", 'rb') and reading in lines to a list. Each line looks a little like: '\xbe\x00\xc8d\xf8d\x08\xe4.\x07~\x03\x9e\x07\xbe\x03\xde\x07\xfe\n' I am having a hard time manipulating this data. If I try and print each line, python freezes, and emits beeping noises (I think there's a binary beep code in there somewhere). How do I go about using this data safely? How can I convert each hex number to decimal?

• Capistrano 3, Rails 4, database configuration does not specify adapter

  - by Kazmin

  When I start cap production deploy it fails like this: DEBUG [4ee8fa7a] Command: cd /home/deploy/myapp/releases/releases/20131025212110 && (RVM_BIN_PATH=~/.rvm/bin RAILS_ENV= ~/.rvm/bin/myapp_rake assets:precompile ) DEBUG [4ee8fa7a] rake aborted! DEBUG [4ee8fa7a] database configuration does not specify adapter You can see that "RAILS_ENV=" is actually empty and I'm wondering why that might be happening? I assume that this is the reason for the latter error that I don't have a database configuration. The deploy.rb file is below: set :application, 'myapp' set :repo_url, '[email protected]:developer/myapp.git' set :branch, :master set :deploy_to, '/home/deploy/myapp/releases' set :scm, :git set :devpath, "/home/deploy/myapp_development" set :user, "deploy" set :use_sudo, false set :default_env, { rvm_bin_path: '~/.rvm/bin' } set :keep_releases, 5 namespace :deploy do desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do # Your restart mechanism here, for example: within release_path do execute " bundle exec thin restart -O -C config/thin/production.yml" end end end after :restart, :clear_cache do on roles(:web), in: :groups, limit: 3, wait: 10 do within release_path do end end end after :finishing, 'deploy:cleanup' end?

• Active record taking Date.today as yesterday

  - by Mongus Pong

  I have a strange one.. I am doing something like : tip = find (:first, :conditions => ["last_shown = ? or last_shown is null", Date.today]) And then a little later on I do : tip.last_shown = Date.today tip.save When I look at output of these queries, ActiveRecord is doing the first query with todays date as I would expect. However, the send query, ActiveRecord is setting the last_shown date to be yesterdays date. Why on earth would it do this? I have config.time_zone = 'UTC' in my environment.rb. I can use Time.now.utc.to_date instead of Date.today but it makes no difference.

• [Python] How do I read binary pickle data first, then unpickle it?

  - by conradlee

  I'm unpickling a NetworkX object that's about 1GB in size on disk. Although I saved it in the binary format (using protocol 2), it is taking a very long time to unpickle this file---at least half an hour. The system I'm running on has plenty of system memory (128 GB), so that's not the bottleneck. I've read here that pickling can be sped up by first reading the entire file into memory, and then unpickling it (that particular thread refers to python 3.0, which I'm not using, but the point should still be true in python 2.6). How do I first read the binary file, and then unpickle it? I have tried: import cPickle as pickle f = open("big_networkx_graph.pickle","rb") bin_data = f.read() graph_data = pickle.load(bin_data) But this returns: TypeError: argument must have 'read' and 'readline' attributes Any ideas?

When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?
