skip created_at field from to rspec response - ruby-on-rails

Could you please help me,
When i run rspec, i got this response.body
"{:id=>1, :email=>\"email1#example.com\", :live=>true, :is_confirmed=>false, :is_pro=>false, :user_profile=>nil, :user_settings=>nil, :subscription_end_at=>nil, :is_trialing=>nil, :created_at=>Mon, 19 Mar 2018 16:45:25 UTC +00:00, :updated_at=>Mon, 19 Mar 2018 16:45:25 UTC +00:00}"
But I want this
"{:id=>1, :email=>\"email1#example.com\", :live=>true, :is_confirmed=>false, :is_pro=>false, :user_profile=>nil, :user_settings=>nil, :subscription_end_at=>nil, :is_trialing=>nil, :created_at=>"Mon, 19 Mar 2018 16:45:25 UTC +00:00", :updated_at=>"Mon, 19 Mar 2018 16:45:25 UTC +00:00"}"
I just want to removed created_at and updated_at attribute from the response because it's give the datetime object instead of string

How to build a monthly range that takes in account the number of days of each month?

I have a range with a start_date, end_date and I want to get the same day of each month for the whole range, so here starting on the 30th of January I should get the 30th of each month:
start_date = Date.new(2019, 1, 30)
end_date = Date.new(2019, 12, 30)
range = (start_date...end_date)
dates = range.step(30).map(&:to_date)
dates
#=> [Wed, 30 Jan 2019,
# Fri, 01 Mar 2019,
# Sun, 31 Mar 2019,
# Tue, 30 Apr 2019,
# Thu, 30 May 2019,
# Sat, 29 Jun 2019,
# Mon, 29 Jul 2019,
# Wed, 28 Aug 2019,

# Sun, 27 Oct 2019,

I was using something like this for weeks but with months when you get to February for example it of course fails, so I would have to adjust to 28th.
I know I could loop and look at the month and do adjustments based on the start_date but it feels like a bad idea.
I think you can use either active support:
require 'active_support/time'
start_date = Date.parse('2019-10-31')
12.times.map { |i| start_date + i.month }
=> [

or adjust: #next_month:
require 'date'
Date.parse('2019-10-31').next_month # => Sat, 30 Nov 2019

Rails - Change TimeWithZone Timezone

I've been banging my head against this for a while and I can't seem to understand how rails timezones and in_time_zone works.
Here is some rails c output that I'd like to understand:
[26] VMM(bby - main - dev)> Time.zone.now
=> Wed, 14 Mar 2018 09:13:17 CDT -05:00
[27] VMM(bby - main - dev)> MyModel.first.started_at
=> Fri, 09 Mar 2018 09:17:00 CST -06:00
[28] VMM(bby - main - dev)> MyModel.first.started_at.in_time_zone(Time.zone)
=> Fri, 09 Mar 2018 09:17:00 CST -06:00
So:
From the first line, the Time.zone seems to be CDT -5.
From the second line, the started_at attribute seem to be CST -6
On the third line, my intention is to change that atribute to use CDT -5, so I'd expect an output of Fri, 09 Mar 2018 10:17:00 CDT -05:00
Why does this behave as it does instead of how I expect it to?
Thanks in advance!

Generate random datetimes in rails with the minutes belongs to range(00, 30)

Event model which has start and end datetime attributes in the database. I want to seed some random events but the event time should be proper.
For example:
6.times { date_range << DateTime.now + (rand * 21) }
generates
[Thu, 03 Aug 2017 21:22:48 +0530,
Tue, 08 Aug 2017 17:36:29 +0530,
Sat, 29 Jul 2017 06:19:51 +0530,
Sat, 29 Jul 2017 13:36:21 +0530,
Thu, 27 Jul 2017 15:08:55 +0530,
Fri, 04 Aug 2017 13:53:03 +0530]
which is the correct behaviour.
But how to generate random datetime like this:
[Thu, 03 Aug 2017 21:00:00 +0530,
Tue, 08 Aug 2017 17:30:00 +0530,
Sat, 29 Jul 2017 06:00:00 +0530,
Sat, 29 Jul 2017 13:00:00 +0530,
Thu, 27 Jul 2017 15:30:00 +0530,
Fri, 04 Aug 2017 13:00:00 +0530]
So in order to display these events properly on a calendar.
Could try separating out each segment and adding them onto the date individually
date_range = 6.times.collect do
DateTime.now.beginning_of_day + # starting from today
rand(21).days + # pick a random day, no further than 3 weeks out
rand(24).hours + # move forward to a random hour on that day
(rand(2) * 30).minutes # and then decide whether to add 30 minutes
end
or, could combine the hours + minutes
date_range = 6.times.collect do
DateTime.now.beginning_of_day + # starting from today
rand(21).days + # pick a random day, no further than 3 weeks out
(rand(48) * 30).minutes # pick a random interval of 30 minutes to add in
end
Found the working solution but not complete:
6.times { date_range << DateTime.parse((DateTime.now + (rand * 21)).beginning_of_hour.to_s) }
[Mon, 31 Jul 2017 06:00:00 +0530,
Thu, 03 Aug 2017 15:00:00 +0530,

Wed, 09 Aug 2017 16:00:00 +0530,
Sat, 12 Aug 2017 13:00:00 +0530]
This can work for now but need some datetime with 30 minutes as well.

Ruby how to get a date to the default format as it's stored in the db

My db is by default storing times as such:
Object.last.created_at
# => Fri, 03 Jul 2015 23:27:50 UTC +00:00
I looked at the strftime docs and I can build that myself, but it seems there must be an easy way to get a regular Date object to that format? Just wondering if there is...
to_datetime gets really close, but not exactly all the way there.
Date.today.to_datetime
# => Sat, 04 Jul 2015 00:00:00 +0000
Any other ideas?
Try this
Time.zone.now
#=> Sat, 04 Jul 2015 20:32:44 UTC +00:00
UPDATE
DateTime.now.in_time_zone
#=> Sat, 04 Jul 2015 20:43:57 UTC +00:00
Oh silly me... it's just
Date.today.in_time_zone
# => Mon, 06 Jul 2015 00:00:00 UTC +00:00

ActiveRecord does not respect daylight saving time (DST)?

We're in the timezone Bern, which is +0100. But since we're now in summertime (we have daylight saving time), the current offset is +0200. In my rails app, I set the timezone using a wrapper in the application controller since I need to have user-based timezones:
around_filter :user_timezone
def user_timezone(&block)
Time.use_zone(current_timezone, &block)
end
Now the strange part:
Time.zone.now # 2013-04-10 10:32:56 +0200
# (correct offset)
SomeArModel.first.created_at # 2013-03-28 17:49:59 +0100
# (incorrect offset, no DST)
Is there any explanation for this?
Thats normal behavior, the DST change happened on Sun Mar 31 01:00:00 UTC 2013.
t = Time.mktime(2013, 03, 31, 1, 15, 0)
6.times do
t += 900
u = Time.at(t.to_i).utc
puts t.to_s + " " + u.to_s
end
output:
Sun Mar 31 01:30:00 +0100 2013 Sun Mar 31 00:30:00 UTC 2013
Sun Mar 31 01:45:00 +0100 2013 Sun Mar 31 00:45:00 UTC 2013
Sun Mar 31 03:00:00 +0200 2013 Sun Mar 31 01:00:00 UTC 2013
Sun Mar 31 03:15:00 +0200 2013 Sun Mar 31 01:15:00 UTC 2013
Sun Mar 31 03:30:00 +0200 2013 Sun Mar 31 01:30:00 UTC 2013
Sun Mar 31 03:45:00 +0200 2013 Sun Mar 31 01:45:00 UTC 2013
