Add validation to prevent out of range for ActiveRecord::Type::Integer with limit 4

Question

I am running into out of range for ActiveRecord::Type::Integer with limit 4 error when typing a number over 10 digits. I want to add a validation to prevent this error from popping up.

this is my model thus far

 def self.find_archived(tenant, time_range, filters={}, options={})
    archived_recording_table = Arel::Table.new(ArchivedRecording.table_name)

    # create duration clauses
    duration_clauses = filters.try(:[],:duration).try(:[],:durations).to_a.each_index.collect{|index|
      duration = filters[:duration][:durations][index]
      case filters[:duration][:operators][index].to_sym
      when :lt
        archived_recording_table[:duration].lt(duration)
      when :gt
        archived_recording_table[:duration].gt(duration)
      end
end

this is my controller

def index

      unless params[:searched] 
        @filters[:duration] ||= Hash.new
        @filters[:duration][:durations] = ['1']
        @filters[:duration][:operators] = [:gt]
      end

      if @filters.try(:[],:duration).try(:[],:durations)
        @filters[:duration][:durations].map!(&:to_i)
      end

      @recording_metadata = RecordingMetadata.find(@tenant, request.session_options[:id], (start_time..end_time), @filters, additional_options)
    end
  end

What i tried soo far to get validation to work in the model

  validates :duration, numericality: { only_integer: true, greater_than: 0, less_than_or_equal_to: 9999999999 }

But I am still getting the same error. I read that changing the column to limit 8 would solve this but is there a workaround where I do not need to change the DB

Answer 1

The max value of a 4-bytes integer column in a database is 2**31 - 1 == 2147483647.

Fo ensure that you cannot write values bigger than that to the database just change your validation to:

validates :duration, numericality: { only_integer: true, 
                                     greater_than: 0, 
                                     less_than:    2**31 }

But looking at your stack trace it feels like the issue is not that you are trying to store a value into the database but instead, you build a query that includes a value that is over that limit and therefore your database complains about an invalid filter.

A workaround might be to limit the maximum duration in the filter by changing this line

duration = filters[:duration][:durations][index]

to

duration = [filters[:duration][:durations][index], (2**31 - 1)].min

Answer 2

The max value for an integer with limit 4 is 2147483647. You will have to increase the limit of the column if you want to allow values greater than 2147483647 but less than or equal to 9999999999
