Overview

Helper for handling API key expiration presets.

Provides a consistent set of expiration options for use in forms, and parsing logic to convert preset strings to actual dates.

Examples:

In your view (form select)

<%= form.select :expires_at_preset,
    ApiKeys::Helpers::ExpirationOptions.for_select %>

In your controller

expires_at = ApiKeys::Helpers::ExpirationOptions.parse(params[:expires_at_preset])
@api_key = current_org.create_api_key!(expires_at: expires_at, ...)

DEFAULT_PRESETS =

Default preset options with human-readable labels

[
  { label: "No Expiration", value: "no_expiration", days: nil },
  { label: "7 days", value: "7_days", days: 7 },
  { label: "30 days", value: "30_days", days: 30 },
  { label: "60 days", value: "60_days", days: 60 },
  { label: "90 days", value: "90_days", days: 90 },
  { label: "1 year", value: "365_days", days: 365 }

Custom presets

ExpirationOptions.for_select(presets: [7, 30, 365])
# => [["No Expiration", "no_expiration"], ["7 days", "7_days"], ["30 days", "30_days"], ["1 year", "365_days"]]

Without "No Expiration"

ExpirationOptions.for_select(include_no_expiration: false)
# => [["7 days", "7_days"], ["30 days", "30_days"], ...]

Parameters:

  • include_no_expiration (Boolean) (defaults to: true) —

    Whether to include "No Expiration" option (default: true)

  • presets (Array<Integer>, nil) (defaults to: nil) —

    Custom list of days to include (e.g., [7, 30, 90]) If nil, uses DEFAULT_PRESETS

Returns:

  • (Array<Array>) —

    Array of [label, value] pairs for select helper

def for_select(include_no_expiration: true, presets: nil)
  options = if presets
              build_custom_presets(presets, include_no_expiration)
            else
              filter_default_presets(include_no_expiration)
            end

  options.map { |opt| [opt[:label], opt[:value]] }
end

.parse(preset) ⇒ ActiveSupport::TimeWithZone?

Parse an expiration preset string into an actual datetime.

Examples:

ExpirationOptions.parse("30_days")  # => 30.days.from_now
ExpirationOptions.parse("no_expiration")  # => nil
ExpirationOptions.parse(nil)  # => nil
ExpirationOptions.parse("invalid")  # => nil

Parameters:

  • preset (String, nil) —

    The preset value (e.g., "30_days", "no_expiration")
