Sometimes Chef fails on the next code (this code not in block or any resource):
tmp = title.force_encoding("ISO-8859-1").encode("UTF-8")
title = tmp.encode('ISO8859-1').force_encoding('UTF-8')
error that I get:
NoMethodError
undefined method `force_encoding' for nil:NilClass
My question is how best practice to ignore any code error and to continue to run rest recipes, thanks
You didn't show where title comes from so they best I can say is to put your code in a ruby_block resource and use the ignore_failure property. You can also use normal Ruby rescue blocks for imperative code but be aware of how that interacts (or rather, doesn't) with resources, see https://coderanger.net/two-pass/ for some details on the loading process Chef uses.

I have a Ruby cli program that can optionally load a user-specified file via require. I would like to unit test this functionality via RSpec. The obvious thing to do is to mock the require and verify that it happened. Something like this:
context 'with the --require option' do
let(:file) { "test_require.rb" }
let(:args) { ["--require", "#{file}"] }
it "loads the specified file"
expect(...something...).to receive(:require).with(file).and_return(true)
command.start(args)
end
end
(That's just typed, not copy/pasted - the actual code would obscure the question.)
No matter what I try, I can't capture the require, even though it's occurring (it raises a LoadError, so I can see that). I've tried a variety of things, including the most obvious:
expect(Kernel).to receive(:require).with(file).and_return(true)
or even:
let(:kernel_class) { class_double('Kernel') }
kernel_class.as_stubbed_const
allow(Kernel).to receive(:require).and_call_original
allow(Kernel).to receive(:require).with(file).and_return(true)
but nothing seems to hook onto the require
Suggestions?
So require is defined by Kernel but Kernel is included in Object so when you call require inside this context it is not necessarily the Kernel module that is processing the statement.
Update
I am not sure if this exactly solves your issue but it does not suffer from the strange behavior exhibited below:
file = 'non-existent-file'
allow(self).to receive(:require).with(file).and_return(true)
expect(self).to receive(:require).with(file)
expect(require file).to eq(true)
Working Example
OLD Answer:
This is incorrect and exists only for posterity due to the up-votes received. Some how works without the allow. Would love it if someone could explain why as I assumed it should raise instead. I believe the issue to be related to and_return where this is not part of the expectation. My guess is we are only testing that self received require, with_file, and that the and_return portion is just a message transmission (thus my updated answer)
You can still stub this like so:
file = 'non-existent-file.rb'
allow_any_instance_of(Kernel).to receive(:require).with(file).and_return(true)
expect(self).to receive(:require).with(file).and_return(true)
require file
Since I am unclear on your exact implementation since you have obfuscated it for the question I cannot solve your exact issue.
Testing ruby-asterisk manager interface with ruby version 1.9.3p0 and gem 1.8.11, for all command and methods its printing the the same output.
Anyone faced similar problem.
Code:
#!/usr/bin/env ruby
require 'ruby-asterisk'
#ami = RubyAsterisk::AMI.new("192.168.1.5",5038)
#ami.login("admin","passs")
puts #ami.command("sip show peers")
Output:
#<RubyAsterisk::Response:0x000000016af710>
Project URL
Problem solved. Didn’t check the readme RESPONSE OBJECT section.
It's working.
var = #ami.command(""sip show peers)
puts var.data
You are putting the Instance of the RubyAsterix. I think after haveing a brief look at the project that most/all of the instance methods returns the instance it self. The reason for doing it that way is that it makes it very easy to chain multiplie actions which makes for a nice syntax/usage.
I think you should remove the puts and allow the gem to display what it wants to display.
I have this Ruby code in a script:
$dev_input=gets.chomp.downcase!
if $dev_input.include? "/"
check_developer_commands()
else
puts ">>Invalid Command<<"
continuing_dev_mode()
end
The problem is, whenever I try and run the script containing this, I get an error spat back at me that says :
dev_continue_main.rb:3:in 'continuing_dev_mode': undefined method 'include?' for nil:NilClass (NoMethodError)
Any idea what this error might be? I'm pretty sure that this is the proper way to use the .include? method. I've done some research, looked at tutorialspoint.com and some other sites, but they agree that this is the proper way to use this method.
I checked the error message and it confirmed that the third line in this script/my example is the source of the problem, so it's not some other instance of this method throwing an error.
Any thoughts? Please Help!
The problem is that $dev_input is nil. That stems from applying downcase! in defining $dev_input. I don't know why you want to possibly assign nil to $dev_input, and at the same time claim that calling include? on it is the right way. I don't get your intention for doing that, but if you instead had $dev_input = gets.chomp.downcase, then it wouldn't cause such error.
I am running a padrino application and have started with the included mailers. I want to test that a mail is sent and had previously had no trouble accessing the Mail::TestMailer object to look at the mails delivered during the test.
That is the background about what I am doing but not precisely the question. I want to know how can a module become available to the runtime environment.
I have this test in two versions
first
def test_mailer
Mail::TestMailer.deliveries.clear
get '/owners/test'
e = Mail::TestMailer.deliveries.pop
puts e.to.to_s
end
second
def test_mailer
get '/owners/test'
Mail::TestMailer.deliveries.clear
e = Mail::TestMailer.deliveries.pop
puts e.to.to_s
end
In the second version this test fails with the error message NoMethodError: undefined method to' for nil:NilClass This makes sense to me. I clear the messages then ask for the last one which should be nil. However when I run the test on the first version the error is NameError: uninitialized constant OwnersControllerTest::Mail
So somehow the get method is causing the Mail object/module to be made available. I don't understand how it can do this. I don't know if this is a rack-test or padrino thing so am unsure what extra information to copy in here.
Add require 'mail' to your test helper.
The issue is explained here: https://github.com/padrino/padrino-framework/issues/1797
I see myself handling similar exceptions in a rather similar fashion repeatedly and would like to use aspects to keep this error handling code outside of the core business logic. A quick search online pulled up a couple of ruby gems (aquarium, aspector, etc) but I don't see a whole lot of downloads for those gems in rubygems. Given that, I want to believe there are probably other nicer ways to deal with this in Ruby.
get '/products/:id' do
begin
product = find_product params[:id]
rescue Mongoid::Errors::DocumentNotFound
status 404
end
end
get '/users/:id' do
begin
user = find_user params[:id]
rescue Mongoid::Errors::DocumentNotFound
status 404
end
end
In the above example, there are 2 Sinatra routes that look for a requested object by ID in MongoDB and throw a 404 if the object were not to be found. Clearly, the code is repetitive and I am looking to find a Ruby way to make it DRY.
You can see answer in this guide.
You code example:
error Mongoid::Errors::DocumentNotFound do
status 404
end
