由 你离开我真会死。 提交于 2020-01-12 07:23:06
问题 I may be approaching this in the wrong direction, so any help would be appreciated. I have a Ruby script which, amongst other things, starts up an executable. I want to start this executable - currently being triggered using system "" - and then continue on with the script. When the script finishes, I want it to exit but leave the executable running. Originally I had the following # Do some work # Start the executable system("executable_to_run.exe") # Continue working But executable_to_run

由 一世执手 提交于 2020-01-04 14:31:25
问题 So I'm writing a Ruby client for a SOAP web service, and I've figured out how to call a simple method: # WebServiceClient.rb require 'soap/wsdlDriver' wsdl_url = 'http://urlmadness?wsdl' service = SOAP::WSDLDriverFactory.new(wsdl_url).create_rpc_driver result = service.simpleMethod(:sayHello => 'Hello') p result.return Now I need to write something that will call a web method that is expecting an attached file as a SOAP MIME Attachment (SwA). I've looked into Ruby's SOAP::Attachment class but

Ruby 1.8 and UTF-8 string case statement compare

由 こ雲淡風輕ζ 提交于 2019-12-24 11:03:43
问题 I have a Rake task (in lib/tasks directory) that I run with cron on my shared web hosting. The problem is that I want to compare a UTF-8 string using case statment but my source code is not UTF-8 encoded. If I save source code as UTF-8 there is error when I try to start it :( What I have to do? May be read this strings from external UTF-8 txt file? P.S. I'm using Ruby 1.8 P.S. I mean compare this way: result = case utf8string when 'АБВ': 1 when 'ГДИ': 2 when 'ЙКЛ': 3 when 'МНО': 4 else 5 end

Preventing timeout when connecting to a URL

由 穿精又带淫゛_ 提交于 2019-12-23 18:53:37
问题 I want to see the time taken to access a url using Benchmark in the code below. I also tried to do the same thing without benchmark.

Both methods end in the same timeout error. require 'open-uri' require 'benchmark' response = nil puts "opening website with benchmark..." puts Benchmark.measure{ response = open('http://mywebsite.com') } puts "Done !" status = response.status puts status Error: opening website

Ruby Array#puts not using overridden implementation?

由 拟墨画扇 提交于 2019-12-11 23:02:27
问题 I am using Ruby 1.8.6 for the following code: # Create an array and override the #to_s on that object thing = [1,2,3] def thing.to_s 'one' end print "Using print: " print thing puts puts "Using puts: " puts thing Output: Using print: one Using puts: 1 2 3 So thing is an Array and I have overridden thing #to_s. print seems to use my overriden implementation while puts does not. Why? I have followed the source code of Kernel#puts and Kernel#print (which are C-implementations) and see that they

由 北城以北 提交于 2019-12-11 12:19:58
问题 According to http://redmine.ruby-lang.org/issues/1183 , Ruby 1.9's {foo: 42} apparently was back-ported to Ruby 1.8.

Ruby - How to invert a Hash with an array values?

由 天大地大妈咪最大 提交于 2019-12-11 10:42:19
问题 Looking for an answer that works on Ruby 1.8.7 : For example lets say I have a hash like this: {"Book Y"=>["author B", "author C"], "Book X"=>["author A", "author B", "author C"]} and I want to get this: { "author A" => ["Book X"], "author B" => ["Book Y", "Book X"], "author C" => ["Book Y", "Book X"] } I wrote a really long method for it, but with large datasets, it is super slow. Any elegant solutions? 回答1: h = {"Book Y"=>["author B", "author C"], "Book X"=>["author A", "author B", "author

Getting error “Cannot allocate memory” for Rails

由 痴心易碎 提交于 2019-12-10 18:44:33
问题 In my project there is one script that returns the list of products which I have to display in a table. To store the input of the script I used IO.popen : @device_list = [] IO.popen("device list").each do |device| @device_list << device end device list is the command that will give me the product list. I return the @device_list array to my view for displaying by iterating it. When I run it I got an error: Errno::ENOMEM (Cannot allocate memory): for IO.popen I have on another script device

DBI Row / delegate behavior between ruby 1.8.7 and 2.1

由 ╄→гoц情女王★ 提交于 2019-12-04 14:22:47
I execute the following code in ruby 1.8.7 to read rows from my database: require 'dbi' db_conn_handle = DBI.connect("DBI:Mysql:host=localhost;database=mydb;port=3306", "root") sth = db_conn_handle.prepare("select accounts.id, accounts.name from accounts;") sth.execute info = sth.to_a puts "Info: #{info[0].class}" info.each do |x, y| puts "#{x} ... #{y}" end From the output it is clear that info[0].class is DBI::Row. This code works perfectly when executed with ruby 1.8.7 (rails 3.2.17) When I try executing it in ruby 2.1.5 / rails 3.2.17, it gives the following error: /home/rjain/.rvm/rubies
