I am trying to make an app for vacation requests but i am facing a problem.I have e model called VacationRequest and a view of VacationRequest where the result will be shown.
VacationRequest.rb model
def skip_holidays
count1 = 0
special_days = Date.parse("2017-05-09", "2017-05-12")
special_days.each do |sd|
if ((start_data..end_data) === sd)
numero = (end_data - start_data).to_i
numro1 = numero - sd
else
numero = (end_data - start_data).to_i
end
end
end
VacationRequest show.htm.erb
here i called the method from model
#vacation_request.skip_holidays
this is showing errors and is not working. Please help me with that!
My approach to this would be the following:
def skip_holidays
special_days = ["2017-05-09", "2017-05-12"].map(&:to_date)
accepted_days = []
refused_days = []
(start_data..end_data).each do |requested_date|
accepted_days << requested_date unless special_days.include?(requested_date)
refused_days << requested_date if special_days.include?(requested_date)
end
accepted_day_count = accepted_days.count
refused_days_count = refused_days.count
end
This way you iterated over all requested dates (the range), checked if the date is a special day - If so, refuse it, otherwise accept it.
In the end you can display statistics about accepted and refused dates.
You cannot create a date range by passing multiple argument to the constructor. Instead call the constructor twice to create a range:
special_days = Date.parse("2017-05-09") .. Date.parse("2017-05-12")
Or if instead you want only the two dates, do:
special_days = ["2017-05-09", "2017-05-12"].map &:to_date
This Date.parse("2017-05-09", "2017-05-12") don`t create a range, only return the first params parsed:
#irb
Date.parse("2017-05-09", "2017-05-12")
=> Tue, 09 May 2017
You can do it this way:
initial = Date.parse("2017-05-09")
final = Date.parse("2017-05-12")
((initial)..final).each do |date|
#rules here.

Basically i am having very simple test where i check if account_id from Grant (so id of his parent) is equal to account_id of Role model.
Test seems ok, but i need to refactor it to use subject/let and to use FactoryGirl and i can't do that even with all the info on this subject i found.
So, test is fine i just need help with refactoring.
It's first time for me working with rails and writing test on it, so i am forced to ask this type of question here.
describe "validations" do
it "should have equal account_id" do
first_acc, second_acc = Account.new, Account.new
first_acc.id, second_acc.id = 10, 11
vlada_role, vlada_grant = Role.new, Grant.new
vlada_role1, vlada_grant1 = Role.new, Grant.new
vlada_role.account_id = first_acc.id
vlada_grant.account_id = second_acc.id
vlada_role.id, vlada_grant.id = 8000, 255
rg = RoleGrant.new
rg1 = RoleGrant.new
rg.role, rg1.role = vlada_role, vlada_role1
rg.grant, rg1.grant = vlada_grant, vlada_grant1
expect(rg.role.account_id).not_to eql(rg.grant.account_id)
expect(rg1.role.account_id).to eql(rg1.grant.account_id)
end
end

First of all, you are sending the spider more time on the same site, though with different form parameters. You have therefore to use dont_filter=True in the request, otherwise Scrapy blocks duplicate calls.
Then it seems to me that the site you are scraping don't allow you to make more than one request during the same session. Try for example to go to http://fcainfoweb.nic.in/PMSver2/Reports/Report_Menu_web.aspx with your browser, compile the form, get the data and than to go back to the initial page: It's impossible. So you have to modify your spider. Here's a very rough code just to give an idea. It works for me, but please don't use it in production!

This question already has an answer here:
"private method 'gets' called for "parker":String
(1 answer)
Closed 6 years ago.
Getting the error
"private method `gets' called for `ot,Room 203,Healthcare Info Session,2014,6,17,14,0\n":String (NoMethodError)"
and not sure where my code is wrong.
Also the first line in appointments.txt:
ot,Room 203,Healthcare Info Session,2014,6,17,14,0
Can someone please let me know what needs to be changed in my code:
appointments = [ ]
file_object = File.open("appointments.txt", "r")
while line = file_object.gets
fields = line.gets.chomp.split(',')
appointment_type = [0]
if appointment_type == 'ot'
location = fields[1]
purpose = fields[2]
year = fields[3].to_i
month = fields[4].to_i
day = fields[5].to_i
hour = fields[6].to_i
minute = fields[7].to_i
appt1 = OneTimeAppointment.new("Dentist", "Cleaning", 4, 45, 5, 20, 2017)
appointments.push(appt1)
else
location = fields[1]
purpose = fields[2]
hour = fields[3].to_i
minute = fields[4].to_i
day = fields[5].to_i
appt2 = MonthlyAppointment.new("Doctor", "Cold", 2, 30, 15)
appointments.push(appt2)
end
end
You can't call gets on a string. You call gets on the file to retrieve the line, but then you go and call gets on that line for some reason. This is incorrect.
A fix looks like this:
File.readlines('appointments.txt') do |line|
fields = line.chomp.split(',')
# ...
end
If you're reading CSV data you may want to consider using the CSV library that comes with Ruby.
I worked up a working code to check if a credit card is valid using luhn algorithm:
class CreditCard
def initialize(num)
##num_arr = num.to_s.split("")
raise ArgumentError.new("Please enter exactly 16 digits for the credit card number.")
if ##num_arr.length != 16
#num = num
end
def check_card
final_ans = 0
i = 0
while i < ##num_arr.length
(i % 2 == 0) ? ans = (##num_arr[i].to_i * 2) : ans = ##num_arr[i].to_i
if ans > 9
tens = ans / 10
ones = ans % 10
ans = tens + ones
end
final_ans += ans
i += 1
end
final_ans % 10 == 0 ? true : false
end
end
However, when I create driver test codes to check for it, it doesn't work:
card_1 = CreditCard.new(4563960122001999)
card_2 = CreditCard.new(4563960122001991)
p card_1.check_card
p card_2.check_card
I've been playing around with the code, and I noticed that the driver code works if I do this:
card_1 = CreditCard.new(4563960122001999)
p card_1.check_card
card_2 = CreditCard.new(4563960122001991)
p card_2.check_card
I tried to research before posting on why this is happening. Logically, I don't see why the first driver codes wouldn't work. Can someone please assist me as to why this is happening?
Thanks in advance!!!
You are using a class variable that starts with ##, which is shared among all instances of CreditCard as well as the class (and other related classes). Therefore, the value will be overwritten every time you create a new instance or apply check_card to some instance. In your first example, the class variable will hold the result for the last application of the method, and hence will reflect the result for the last instance (card_2).
TL;DR: I need to get the difference between HH:MM:SS.ms and HH:MM:SS.ms as HH:MM:SS:ms
What I need:
Here's a tricky one. I'm trying to calculate the difference between two timestamps such as the following:
In: 00:00:10.520
Out: 00:00:23.720
Should deliver:
Diff: 00:00:13.200
I thought I'd parse the times into actual Time objects and use the difference there. This works great in the previous case, and returns 00:0:13.200.
What doesn't work:
However, for some, this doesn't work right, as Ruby uses usec instead of msec:
In: 00:2:22.760
Out: 00:2:31.520
Diff: 00:0:8.999760
Obviously, the difference should be 00:00:8:760 and not 00:00:8.999760. I'm really tempted to just tdiff.usec.to_s.gsub('999','') ……
My code so far:
Here's my code so far (these are parsed from the input strings like "0:00:10:520").
tin_first, tin_second = ins.split(".")
tin_hours, tin_minutes, tin_seconds = tin_first.split(":")
tin_usec = tin_second * 1000
tin = Time.gm(0, 1, 1, tin_hours, tin_minutes, tin_seconds, tin_usec)
The same happens for tout. Then:
tdiff = Time.at(tout-tin)
For the output, I use:
"00:#{tdiff.min}:#{tdiff.sec}.#{tdiff.usec}"
Is there any faster way to do this? Remember, I just want to have the difference between two times. What am I missing?
I'm using Ruby 1.9.3p6 at the moment.
Using Time:
require 'time' # Needed for Time.parse
def time_diff(time1_str, time2_str)
t = Time.at( Time.parse(time2_str) - Time.parse(time1_str) )
(t - t.gmt_offset).strftime("%H:%M:%S.%L")
end
out_time = "00:00:24.240"
in_time = "00:00:14.520"
p time_diff(in_time, out_time)
#=> "00:00:09.720"
Here's a solution that doesn't rely on Time:
def slhck_diff( t1, t2 )
ms_to_time( time_as_ms(t2) - time_as_ms(t1) )
end
# Converts "00:2:22.760" to 142760
def time_as_ms( time_str )
re = /(\d+):(\d+):(\d+)(?:\.(\d+))?/
parts = time_str.match(re).to_a.map(&:to_i)
parts[4]+(parts[3]+(parts[2]+parts[1]*60)*60)*1000
end
# Converts 142760 to "00:02:22.760"
def ms_to_time(ms)
m = ms.floor / 60000
"%02i:%02i:%06.3f" % [ m/60, m%60, ms/1000.0 % 60 ]
end
t1 = "00:00:10.520"
t2 = "01:00:23.720"
p slhck_diff(t1,t2)
#=> "01:00:13.200"
t1 = "00:2:22.760"
t2 = "00:2:31.520"
p slhck_diff(t1,t2)
#=> "00:00:08.760"
I figured the following could work:
out_time = "00:00:24.240"
in_time = "00:00:14.520"
diff = Time.parse(out_time) - Time.parse(in_time)
Time.at(diff).strftime("%H:%M:%S.%L")
# => "01:00:09.720"
It does print 01 for the hour, which I don't really understand.
In the meantime, I used:
Time.at(diff).strftime("00:%M:%S.%L")
# => "00:00:09.720"
Any answer that does this better will get an upvote or the accept, of course.
in_time = "00:02:22.760"
out_time = "00:02:31.520"
diff = (Time.parse(out_time) - Time.parse(in_time))*1000
puts diff
OUTPUT:
8760.0 millliseconds
Time.parse(out_time) - Time.parse(in_time) gives the result in seconds so multiplied by 1000 to convert into milliseconds.
