Currently, I have 3 columns : booking_date, booking_time_from, booking_time_to.
Problem is how can i get all data have booking time 2 hours ago using Active Support ?
Booking.where([booking_time], 2.hours.ago.to_datetime)
I'm not sure about what's the difference between booking_time_from and booking_time_to, and which column that the booking time you're referring here. Let's assume it's booking_time_to, you can
Booking.where("booking_time_to < ?", 2.hours.ago)

I have saved data to fields in CloudKit and I have queried for the posts by date in decending order and by getting the one at index(0) I have the last post. My question is how do I separate out the various fields and use them to populate the text in various labels in my view. Here is what I have for the latest post query.
<CKRecord: 0x104e5b600; recordID=157F08E2-FF00-42DD-8B89-7CB10FAC81B6:(_defaultZone:__defaultOwner__), recordChangeTag=kk6d3s69, values={ temperature=54, trip=50, level=53, battery=64, date=1-20-2021 20:57:09 }, recordType=MyPoolInfo>
If someone could help me out I would appreciate it. Thanks
I figured this out. This is a dictionary. So I just called the following:
NSLog(#"temperature:%#",[dictionary objectForKey:#"temperature"]) ;
NSLog(#"date:%#",[dictionary objectForKey:#"date"]) ;
NSLog(#"trip:%#",[dictionary objectForKey:#"trip"]) ;
NSLog(#"battery:%#",[dictionary objectForKey:#"battery"]) ;
NSLog(#"level:%#",[dictionary objectForKey:#"level"]) ;
I could then fill in the label.text like this:
self.DateLabel.text =[dictionary objectForKey:#"date"];
in case anyone needs to know.

I want to calculate the number of months between two dates. I want the result in decimal point. For example, if my date range is "2017-02-01" to "2017-03-1", then I am expecting the number of months to be something like 1.033 in decimal.
Please help.
You should be able to do something like this
#Mondel.time_diff_in_months("2017-03-01", "2017-02-01")
def time_diff_in_months(grater_date, lesser_date)
Time.at(grater_date.to_time - lesser_date.to_time).month # 1
end
I hope that this helps

I'm trying to run a for loop and every time a loop runs through a UIButton is allocated and initialized. The issue is that all of these buttons need different names. Is there a way to name the button based on the value of the integer in the for loop?
Is sounds like you want to put the buttons in an NSArray. Items in the array can be referenced by an index into the array.

I am trying to populate column_name with items from #enc. Problem is #update_all updates all fields with last item in array?
Last item is "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n".
I am trying to populate with all items from array not just last.
I hope question is clear?
I tried #update_attributes, but no success?

Thanks

PaymentMethod.all.each_with_index do |payment, n = 0|
