Why cannot I use allow_blank together with_options?

Hi there,

I was using it on 4.1.7, but when I upgrade to 4.2.5 it does not work
more

with_options allow_blank: true do |v|

…

end

allow_blank doesn’t included
here:

github.com

rails/rails/blob/main/activemodel/lib/active_model/validations.rb#L90


      
          #     attr_accessor :first_name, :last_name
          #
          #     validates_each :first_name, :last_name, allow_blank: true do |record, attr, value|
          #       record.errors.add attr, "starts with z." if value.start_with?("z")
          #     end
          #   end
          #
          # Options:
          # * <tt>:on</tt> - Specifies the contexts where this validation is active.
          #   Runs in all validation contexts by default +nil+. You can pass a symbol
          #   or an array of symbols. (e.g. <tt>on: :create</tt> or
          #   <tt>on: :custom_validation_context</tt> or
          #   <tt>on: [:create, :custom_validation_context]</tt>)
          # * <tt>:allow_nil</tt> - Skip validation if attribute is +nil+.
          # * <tt>:allow_blank</tt> - Skip validation if attribute is blank.
          # * <tt>:if</tt> - Specifies a method, proc, or string to call to determine
          #   if the validation should occur (e.g. <tt>if: :allow_validation</tt>,
          #   or <tt>if: Proc.new { |user| user.signup_step > 2 }</tt>). The method,
          #   proc or string should return or evaluate to a +true+ or +false+ value.
          # * <tt>:unless</tt> - Specifies a method, proc, or string to call to
          #   determine if the validation should not occur (e.g. <tt>unless: :skip_validation</tt>,

Is there a reason?

Thanks

That is not what with_options is for, it is for grouping conditional
validations. Show us the rest of the validation so we can see what
you are trying to do.
