I'm new to ruby and I'm trying to re-structure my script which adds some servers to zabbix monitor etc.The issue that I'm facing is below:
zbx = ZabbixApi.connect(
:url => 'http://zabbixserver.net/zabbix/api_jsonrpc.php',
:user => 'admin',
:password => 'admin'
)
def createtemplate
zbx.templates.create(
:host => "RealDoc MS Template",
:groups => [:groupid => zbx.hostgroups.get_id(:name => "RealDoc")]
) ..../will create Items, graphs etc...
end
if templateid.empty?
createtemplate
else
puts "Template Exists"
end
When is accessing the createtemplate method it's throwing the following error: undefined local variable or method `zbx' for main:Object (NameError)
well zbx isn't in scope, as it isn't a global. you have a couple options.
either pass it into the method
def createtemplate(zbx)
zbx.templates.create(
:host => "RealDoc MS Template",
:groups => [:groupid => zbx.hostgroups.get_id(:name => "RealDoc")]
) ..../will create Items, graphs etc...
end
if templateid.empty?
createtemplate zbx
else
puts "Template Exists"
en
or you can make it global with a $.
$zbx = ZabbixApi.connect(
:url => 'http://zabbixserver.net/zabbix/api_jsonrpc.php',
:user => 'admin',
:password => 'admin'
)
def createtemplate
$zbx.templates.create(
:host => "RealDoc MS Template",
:groups => [:groupid => zbx.hostgroups.get_id(:name => "RealDoc")]
) ..../will create Items, graphs etc...
end
if templateid.empty?
createtemplate
else
puts "Template Exists"
end
I would do the first option, as global variables should be used sparingly, but in such a short script it probably doesn't matter that much..
It's working with adding the variable to our method def createtemplate(zbx)
, and the same thing when you are calling the methood , you will call it with zbx variable.

There are other questions pertaining to this, but they all seems to be < Rails 4, and what's more, they're not too detailed!
They all talk about creating a module to share these common validations in:
require 'active_record'
module ContactValidations
def self.included(base_class)
base_class.class_eval do
include ContactValidations::InstanceMethods
# model validations
validates_presence_of(:name, :message => 'You must provide a company name.')
validates_presence_of(:street, :message => 'You must provide a company street.')
validates_presence_of(:city, :message => 'You must provide a company city.')
validates_presence_of(:post_code, :message => 'You must provide a company post code.')
validates_numericality_of(:telephone, :on => :create, :message => 'Telephone should be a number with no spaces.', :if => :telephone_given?)
validates_numericality_of(:area_code, :on => :create, :message => 'Telephone area code should be a number with no spaces.', :if => :area_code_given?)
validates_numericality_of(:fax, :on => :create, :message => 'Fax should be a number with no spaces.', :if => :fax_given?)
validates_numericality_of(:fax_area_code, :on => :create, :message => 'Fax area code should be a number with no spaces.', :if => :fax_area_code_given?)
validates_format_of(:web, :with => /^((http)?:\/\/)?(www\.)?([a-zA-Z0-9]+)(.[a-zA-Z0-9]{2,3})(\.[a-zA-Z0-9]{2,3})$/, :on => :create, :message => 'Web address is invalid. Example: http://www.domain or http://domain.', :if => :web_given?)
validates_format_of(:email, :with => /^([a-zA-Z0-9_\-\.]+)#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/, :on => :create, :message => 'Th email address given is invalid.', :if => :email_given?)
validates_uniqueness_of(:email, :message => 'This email is already given.')
end
end
module InstanceMethods
def telephone_given?
!telephone.blank?
end
def fax_given?
!fax.blank?
end
def web_given?
!web.blank?
end
def email_given?
!email.blank?
end
def area_code_given?
!area_code.blank?
end
def fax_area_code_given?
!fax_area_code.blank?
end
end
end
But I for one have no idea where such a file should be saved. In the lib directory? All files in the lib directory are included, seems a bit wasteful for a module I only want to be included in a two or three models...
Does Rails 4 have an inbuilt way to share validations?
If not, where should I save my custom module?
And just to be super clear, how should I require this module in the models that need to include these validations?
Create the module in app/models/concerns, then include them in your classes with:
include ContactValidations
In this way Rails will automatically load the shared modules and make them available for you to include.
you should also have a look at validates_with
https://api.rubyonrails.org/v6.0.3.3/classes/ActiveModel/Validations/ClassMethods.html#method-i-validates_with
From the below sample code i am able to test the working to list all Tasks in a project.
I want to add New tasks Automatically under a User Story US1234.
I have some 50 User Story in excel to Enter with Task fields (Name ,description, estimate ,To do ,etc... ) ,I want to automate this work.
How to create a task under a user story with the Task fields using REST api in ruby.
There was not much of help with this link http://developer.rallydev.com/help/ruby-toolkit-rally-rest-api
require 'rubygems'
require 'rally_rest_api'
rally= RallyRestAPI.new(:base_url =>"https://rally1.rallydev.com/slm", :username => "harsha.gowda#xyz.com", :password => "xyz123")
projects = rally.find(:project) { equal:name, "XYZ Engineering - Scrum Team 2"}
projects.each do |project|
# puts project.name
tasks = rally.find(:task, :project => project, :fetch => true) {equal :State, "Defined"}
tasks.each do |task|
puts task.name
end
end
You should be able to find most of the answers to your questions here: http://rally-rest-api.rubyforge.org/crud.html.
Here is a basic example, which iterates through each Task on a User Story:
require 'rubygems'
require 'rally_rest_api'
rally= RallyRestAPI.new(:base_url => url, :username => user, :password => pw)
project = (rally.find(:project) { equal :name, name}).first()
rally.find(:hierarchical_requirement, :project => project) {equal :some_field, some_value}.each{ |hr|
hr.tasks.each{ |task|
task.update(:some_field1 => some_value1)
task.update(:some_field2 => some_value2)
task.update(:some_field3 => some_value3)
task.update(:some_field4 => some_value4)
}
}
I don't know how you intend on updating each individually, so you'll have to modify it with your own logic.
I am writing a small sinatra application that I am integrating with Authlogic (following https://github.com/ehsanul/Sinatra-Authlogic-Template)
Everything works except for when I try to login. I get the following error:
NameError at /login
undefined local variable or method `active' for #<User:0x000001040208f0>
I am including the authlogic gem versus including it as a vendor. So my Sinatra app is not exactly the same as the one on Github.
Any and all inquiries will be MUCH appreciated!! Thanks!
Found out my issue.
Here is the model according to the Github page:
class User < ActiveRecord::Base
acts_as_authentic do |c|
# Bcrypt is recommended
#crypto_provider = Authlogic::CryptoProviders::BCrypt
c.perishable_token_valid_for( 24*60*60 )
c.validates_length_of_password_field_options =
{:on => :update, :minimum => 6, :if => :has_no_credentials?}
c.validates_length_of_password_confirmation_field_options =
{:on => :update, :minimum => 6, :if => :has_no_credentials?}
end
def active?
active
end
def has_no_credentials?
crypted_password.blank? #&& self.openid_identifier.blank?
end
def send_activation_email
Pony.mail(
:to => self.email,
:from => "no-reply#domain.tld",
:subject => "Activate your account",
:body => "You can activate your account at this link: " +
"http://domain.tld/activate/#{self.perishable_token}"
)
end
def send_password_reset_email
Pony.mail(
:to => self.email,
:from => "no-reply#domain.tld",
:subject => "Reset your password",
:body => "We have recieved a request to reset your password. " +
"If you did not send this request, then please ignore this email.\n\n" +
"If you did send the request, you may reset your password using the following link: " +
"http://domain.tld/reset-password/#{self.perishable_token}"
)
end
end
I removed all of the mail methods but my script was failing on the active? method because it was looking for an active column in the users table. Since I am unable to append this column to the table (due to data integrity with another system) I simply told my method to return true
My User.rb
class UserSession < Authlogic::Session::Base
end
class User < ActiveRecord::Base
acts_as_authentic do |c|
end
def active?
return true
end
end
Hope this helps someone!
I have no idea what I have done here, but I have attempted to get one controller in Rails to queue a job onto Resque, which then a worker connects to and does the heavy lifting (I.E. comparisons, database entries).
However, the tasks are not even running, since there are no clear instructions for setting Resque up.
Copy and paste's below:
Also available in Gist format!
This is the exception line from Hoptoad:
NoMethodError: undefined method 'perform' for Violateq:Module
This is the contents of the "worker" file:
module Violateq
#queue = :violateq
def perform(nick, rulenumber)
# Working for the weekend!!!
puts "I got a nick of #{nick} and they broke #{rulenumber}"
#violation = Violation.new(nick, rulenumber)
puts "If you got this far, your OK"
log_in(:worker_log, {:action => "Violate d=perfom", :nick => nick, :rulenumber => rulenumber, :status => "success"})
#rescue => ex
# notify_hoptoad(ex)
# log_in(:worker_log, {:action => "Violate d=perfom", :nick => nick, :rulenumber => rulenumber, :status => "failure"})
end
end
This is the contents of the "web_controller" file:
class IncomingController < ApplicationController
require 'mail'
skip_before_filter :verify_authenticity_token
def create
message = Mail.new(params[:message])
# Push the message into the queue
Resque.enqueue(Violateq, message.from.to_s, message.subject.to_s)
log_in(:endpoint_log, {:action => "IncomingController d=create", :subject => message.subject, :message => message.body.decoded})
render :text => 'success', :status => 200 # a status of 404 would reject the mail
rescue => ex
notify_hoptoad(ex)
render :text => 'failure', :status => 500
end
end
Thank you very much for your time, and if you would like any more information, please do not hesitate to contact me,

Fixed.
Changed def perform to def self.perform
Then it worked
Thanks,

Having integrated merb_auth_password_slice as per the README, I can successfully login as redirect_after_login is being triggered, although session.authenticated? returns false.
Just trying the basic auth strategy for now (password form), can't seem to get it working, any ideas?
My init file:
require 'dm-validations'
dependencies "merb-more", "merb_helpers", "merb-slices", "merb_auth_password_slice"
Merb::BootLoader.before_app_loads do
DataMapper.setup(:default, "sqlite3://config/dev.db")
end
Merb::BootLoader.after_app_loads do
# have already done this
# raise "You must specify a valid openid in Merb.root/config/open_id to use this example app" unless File.exists?(Merb.root / "config" / "open_id")
# # DataMapper.auto_migrate!
# User.create(:login => "admin",
# :password => "password", :password_confirmation => "password",
# :email => "admin#example.com",
# :identity_url => File.read(Merb.root / "config" / "open_id"))
end
Merb::Config.use do |c|
c[:session_secret_key] = 'my key'
c[:session_store] = 'cookie'
end
Setup.rb
class Authentication
def store_user(user)
return nil unless user
user.id
end
def fetch_user(session_info)
User.get(session_info)
end
end # Authentication
# before(nil, :only => [:update, :destroy]) { session.abandon! }
This is the culprit in the slice's session controller
