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?
Help.
Thanks
#enc=["hUt7ocoih//kFpgEizBowBAdxqqbGV1jkKVipVJwJnPGoPtTN16ZAJvW9tsi\n3inn\n", "wGNyaoEZ09jSg+/IclWFGAXzwz5lXLxJTUKqCFIiOy3ZXRgdwFUsNf/75R2V\nZm83\n", "MPq3KSzDzLvTeYh+h00HD+5FAgKoNksykJhzROVZWbIJ36WNoBgkSoicJ5wx\nog0g\n"]
#enc.each do |i|
PaymentMethod.update_all(enc_number: i)
end
PaymentMethod.all.each_with_index do |payment, n = 0|
payment.update_column(:enc_number, #enc[n])
n +=1
end

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.

Sorry for my English. I have a model with some field.
How to add a number to a current value in field?
I want to add the number several times
i generated scaffold.I use this to create modal. But i want to add number to a current value when i clicked submit
#foo = Foo.first
#foo.bar += 10
#which is a shorter way of saying #foo.bar = #foo.bar + 10
#foo.save
If this isn't helpful, please add some more details to your question, eg your example code you have so far.

I'm trying to do a simple login form that just compare the value that you insert into the input in HTML to the data you had in the database. How can I do it?
Setup a controller and compare the params hash.
expected_value = '...'
if params[:form_value] == expected_value
do_something()
else
do_something_else()
end
