I am developing an application using ruby and qt as front end. I used qtdesigner to draw gui and converted the code using rbuic4. But i am unable get any action for buttons placed on main programm. I created main.rb and called generated code using require './muprogramm.rb'. Here is the sample code for opening file dialog for button mbusb_close (object name)
require './muprogramm.rb'
require 'Qt4'
class Form < Qt::Widget
slots 'file_dialog()'
def initialize(parent = nil)
super
#ui = Ui_Frame.new
#ui.setupUi(self)
Qt::Object.connect(#ui.mbusb_close, SIGNAL('clicked()'), self, SLOT('file_dialog()'))
end
def file_dialog
f = Qt::FileDialog
text = File.new(f.getOpenFileName).read
##ui.editor_window.setText 'WikiBooks: Ruby'
end
end
a = Qt::Application.new(ARGV)
u = Ui_Frame.new
w = Qt::Frame.new
u.setupUi(w)
w.show
a.exec
The resource available in the net is vague. Any help is appreciated
Just use the subclass that you created directly:
require './muprogramm.rb'
require 'Qt4'
class Form < Qt::Widget
slots 'file_dialog()'
def initialize(parent = nil)
super
#ui = Ui_Frame.new
#ui.setupUi(self)
Qt::Object.connect(#ui.mbusb_close, SIGNAL('clicked()'), self, SLOT('file_dialog()'))
end
def file_dialog
f = Qt::FileDialog
text = File.new(f.getOpenFileName).read
##ui.editor_window.setText 'WikiBooks: Ruby'
end
end
a = Qt::Application.new(ARGV)
w = Form.new
w.show
a.exec

I'm trying to override the after_failed_example method so I can inflict some custom file naming on our screenshots. I'm loading the module as an initializer.
So far, so good, but the Capybara.page.current_url is blank, making me think I need to require something additional?
require "capybara-screenshot/rspec"
module Capybara
module Screenshot
module RSpec
class << self
attr_accessor :use_description_as_filename
attr_accessor :save_html_file
end
self.use_description_as_filename = true
self.save_html_file = true
def self.after_failed_example(example)
if example.example_group.include?(Capybara::DSL) # Capybara DSL method has been included for a feature we can snapshot
Capybara.using_session(Capybara::Screenshot.final_session_name) do
puts ">>>> Capybara.page.current_url: " + Capybara.page.current_url.to_s
if Capybara::Screenshot.autosave_on_failure && failed?(example) && Capybara.page.current_url != ''
saver = Capybara::Screenshot.new_saver(Capybara, Capybara.page, Capybara::Screenshot.save_html_file?, set_saver_filename_prefix(example))
saver.save
example.metadata[:screenshot] = {}
example.metadata[:screenshot][:html] = saver.html_path if saver.html_saved?
example.metadata[:screenshot][:image] = saver.screenshot_path if saver.screenshot_saved?
end
end
end
private
def self.set_saver_filename_prefix(example)
return example.description.to_s.gsub(" ", "-") if Capybara::Screenshot.use_description_as_filename?
return Capybara::Screenshot.filename_prefix_for(:rspec, example)
end
end
end
end
end
This is successfully overriding the capybara-screenshot/rspec method, and any of the Capybara::Screenshot static information is accessible, but not Capybara session related information (afa I can tell).
For example, Capybara.page.current_url.to_s is null when overridden, but present when not.
I was missing a require (kind of silly mistake):
require 'capybara/rspec'
I am new to ruby and this site so please bear with me! I have googled endlessly to no fruition.
I am trying to pass in a college object to my class method scrape_college_info that I created in the previous class method scrape_illinois_index_page, so that I may scrape the next level of information for the specific college the user selects using Pry and Nokogiri. Unfortunately, I keep getting an argument error.
I know it isn't the prettiest, but this is my code right now:
class College
attr_accessor :name, :location, :size, :type, :url
BASE_PATH = "https://www.collegesimply.com/colleges/illinois/"
def self.college
self.scrape_colleges
end
def self.scrape_colleges
colleges = self.scrape_illinois_index_page
colleges
end
def self.scrape_illinois_index_page
doc = Nokogiri::HTML(open(BASE_PATH))
# binding.pry
colleges = []
doc.xpath("//tr").each do |doc|
college = self.new
if doc.css("td")[0] != nil
college.name = doc.css("td")[0].text.strip
end
if doc.css("td")[1] != nil
college.location = doc.css("td")[1].text.strip
end
if doc.css('table.table tbody tr td:nth-child(1) a')[0] != nil
college.link = doc.css('table.table tbody tr td:nth-child(1) a')[0]['href']
end
colleges << college
end
colleges
end
def self.scrape_college_info(college)
doc = Nokogiri::HTML(open(BASE_PATH + "#{college.link}"))
end
end
Try below code to get college.link.
if doc.css("td")[0] != nil
college.name = doc.css("td")[0].text.strip
college.link = doc.css("td")[0].css("a").map{|a| a['href']}[0]
end
Now you can pass college link like :
def self.scrape_college_info(college)
doc = Nokogiri::HTML(open("https://www.collegesimply.com" + "#{college.link}"))
end
Hope this will solve your problem. Please let me know, if it works for you.
Try using URI.join:
new_url = URI.join(BASE_PATH, college.link).to_s
I have some experience of Selenium in Python and Cucumber/Watir/RSpec in Ruby, and can write scripts that execute successfully, but they aren't using classes, so I am trying to learn more about classes and splitting the scripts up in to pageobejcts.
I found this example to learn from: http://watir.com/guides/page-objects/ so copied the script and made some minor edits as you'll see below.
I'm using SublimeText 3.x with Ruby 2.4.x on Win10, so you know what tools I'm using.
I put the whole script in to a single .rb file (the only differences are that I replaced the URL and the elements to enter the username and password) and tried to execute it and get the following error:
C:/selenium/ruby/lotw/lotwlogin.rb:3:in `<main>': uninitialized constant Site (NameError).
I added the top line (required 'watir') line and it made no difference to the error encountered.
So I have in lotwlogin.rb essentilly the structure and syntax of the original script with custom elements. However, the core structure is reporting an error and I don't know what to do about it.
Here is my script:
require 'watir'
site = Site.new(Watir::Browser.new :chrome) # was :firefox but that no longer works since FF63
login_page = site.login_page.open
user_page = login_page.login_as "testuser", "testpassword" # dummy user and password for now
user_page.should be_logged_in
class BrowserContainer
def initialize(browser)
#browser = browser
end
end
class Site < BrowserContainer
def login_page
#login_page = LoginPage.new(#browser)
end
def user_page
#user_page = UserPage.new(#browser)
end
def close
#browser.close
end
end
class LoginPage < BrowserContainer
URL = "https://lotw.arrl.org/lotw/login"
def open
#browser.goto URL
##browser.window.maximize
self # no idea what this is for
end
def login_as(user, pass)
user_field.set user
password_field.set pass
login_button.click
next_page = UserPage.new(#browser)
Watir::Wait.until { next_page.loaded? }
next_page
end
private
def user_field
#browser.text_field(:name => "login")
end
def password_field
#browser.text_field(:name => "password")
end
def login_button
#browser.button(:value => "Log On")
end
end # LoginPage
class UserPage < BrowserContainer
def logged_in?
logged_in_element.exists?
end
def loaded?
#browser.h3 == "Welcome to Your Logbook of the World User Account Home Page"
end
private
def logged_in_element
#browser.div(:text => "Log off")
end
end # UserPage
Any assistance how to not get the Site error would be appreciated.
Thanks
Mike
You define class Site only a few lines below. But at that point, it's not yet known.
Move this logic to after all class definitions:
site = Site.new(Watir::Browser.new :chrome) # was :firefox but that no longer works since FF63
login_page = site.login_page.open
user_page = login_page.login_as "testuser", "testpassword" # dummy user and password for now
user_page.should be_logged_in
I am still quite fresh to Ruby, and especially testing in Ruby. Hopefully the code is not a trainwreck :) I am having issues using any_instance with the Twitter gem, while it works fine on my own classes.
This is (what I believe) the relevant code
require 'twitter'
require 'minitest/unit'
require 'mocha/mini_test'
omitting for brevity....
args = { id: 573536452149182464, id_str: 73536452149182464, text: 'This is an initial tweet from the user'}
initial_tweet = ::Twitter::Tweet.new(args)
::Twitter::REST::Timelines.any_instance.stubs(:user_timeline).returns(initial_tweet)
The code produces the following error:
Minitest::UnexpectedError: NoMethodError: undefined method `any_instance|' for Twitter::REST::Timelines:Module
Are principles to stubbing gems different, am I approaching it wrong?
EDIT: I have added the entire code for the two classes below.

So I've been trying to make ruby read my Qt4 design and it's not working, at all.
I've created a design in Qt4 Designer and saved it as a .ui file. Then I used rbuic4 to convert it to a design_ui.rb and Qt4. My current ruby main file looks like this:
require 'gui/design_ui.rb'
require 'Qt4'
class AppMain < Ui_MainWindow
def initialize(app)
#app = app
end
end
# create and show dialog
if $0 == __FILE__
app = Qt::Application.new(ARGV)
dialog = AppMain.new(app)
dialog.show
app.exec
end
I Seriously can't find a decent guide to properly using ruby and Qt4 Designer. They all do different stuff and none of them works. Please help a newbie out here?
Something like this:
class AppMain < Qt::MainWindow
def initialize(parent = nil)
super
#ui = Ui_Main_window.new
#ui.setupUi self
end
end
Then
application = Qt::Application.new(ARGV)
main_window = AppMain.new
main_window.show
application.exec
