Can you add a failing spec?
At the moment I do not understand how it is possible that a Numeric value passes !value.respond_to?(:to_time)
pry(main)> ValidatesTimeliness::VERSION
=> "7.0.0.beta1"
pry(main)> String.method_defined?(:to_time)
=> true
pry(main)> Numeric.method_defined?(:to_time)
=> false

# String
pry(main)> "444".respond_to?(:to_time)
=> true
pry(main)> "444".respond_to?(:to_date)
=> true
# Integer
pry(main)> 444.respond_to?(:to_time)
=> true
pry(main)> 444.respond_to?(:to_date)
=> false

Which would mean this guard would still fail, because the value is actually a string.
>> "444.0".is_a?(Numeric)
false

But as @tagliala said. we'll need a failing spec for this. It is not clear how this occurs.

The only thing that I can think of is that Numeric has been enhanced with to_time by another library, but that same gem does not define to_date. However, even in this use case that would fail the next line when methods like acts_like?(:time) are invoked. This is why a reduced failing test case would help

Example:
# app/models/item.rb
validates_date :expire_date# console:
> item = Item.new(expire_date: 444)
> item.valid?
NoMethodError: undefined method `to_date' for 444:IntegerThere was a problem hiding this comment.
Hi, thanks for the clarification.
The
Numericvalues are responds to"to_time"but not"to_date".
This is the part that does not sound.
Is there any third party library defining to_time on Numeric elements? Can you check where to_time is defined?
I've setup a pretty basic application at https://github.com/diowa/ruby3-rails7-bootstrap-heroku/tree/validates-timeliness
> 444.respond_to?(:to_time)
=> false
[2] pry(main)> Item.new(expire_date: 444).valid?
=> false
However... @adzap probably there could be a better detection if the timeliness helpers are available on the given value. This can also improve third-party compatibility
Run `Item.new(expire_date: 444).valid?` in console
When the passed value is a Numeric value, then we get an exception 👇
=>
NoMethodError: undefined method "to_date" for 444:IntegerSo, this PR is to handle that case!
@adzap I hope you like this tiny PR and merge it.
Regards 🎉
