How to add time to datetime ruby?

Question

Ruby on Rails

params[:event][:start_time] =params [:event][:start_time] + 1.day
        params[:event][:end_time] = params[:event][:start_time] + 1.day

Controller for events, where I first receive data from forms, and then I want to add 1 day to them, BUT:
the error comes out like this
no implicit conversion of Symbol into Integer
. I understand that the data in params is stored as a string, but I don’t know how to fix this code

Answer 1

1318996912 if time passes in this form, then do this
if in a different format, here is the dock by the method apidock.com/ruby/DateTime/strptime/class

Answer 2

If you want to add dates, then get the Datetime from a string.
But from the error, it seems that your params[:event] returns not a hash, but an array, or a string and ruby ​​tries to convert :start_time to an integer to get the element by index.
