Simple_form: Using `b.use` in the initializer does not enable a particular extension

[franks921]

Hi

I'm experiencing a problem with the optional extensions. I want to enable the :min_max extension in the initializer and it does not seem to add the attributes unless I use min_max: true on the input directly. I'm trying to see if I've missed anything and from the documentation and Google searches, it does not appear that I have.

Environment

• Ruby 2.6.5
• Rails 5.2.0
• Simple Form 5.0.1

Current behavior

I completely reset config/initializers/simple_form.rb and I'm still not getting the desired behavior.

Wrapper

config.wrappers :default, class: :input,
  hint_class: :field_with_hint, error_class: :field_with_errors, valid_class: :field_without_errors do |b|
  b.use :html5
  b.use :placeholder
  b.optional :maxlength
  b.optional :minlength
  b.optional :pattern
  b.use :min_max
  b.optional :readonly
  b.use :label_input
  b.use :hint,  wrap_with: { tag: :span, class: :hint }
  b.use :error, wrap_with: { tag: :span, class: :error }
end

Model:

class VitalityHealthCheck::Adult

  include ActiveModel::Model
  include ActiveModel::Validations

  attr_accessor :vitality_check_medical_systolic

  validates :vitality_check_medical_systolic,
    presence:     true,
    numericality: { greater_than_or_equal_to: 70, less_than_or_equal_to: 240 }

end

View example (slim):

= simple_form_for @note.vhc,
  as:     :vitality_health_check_report,
  method: :patch,
  remote: true,
  url:    consultation_note_vitality_health_check_path(@note.consultation, @note.note) do |f|

  = f.input :vitality_check_medical_systolic

Generated HTML:

<input class="string required" type="text" name="vitality_health_check_report[vitality_check_medical_systolic]" id="vitality_health_check_report_vitality_check_medical_systolic">

Expected behavior

I expect the following HTML to be rendered:

<input class="string required" min="70" max="240" type="text" name="vitality_health_check_report[vitality_check_medical_systolic]" id="vitality_health_check_report_vitality_check_medical_systolic">

Could you please provide us a sample application that reproduces the issue in isolation?

That would help us find the issue.

Thank you for the response @feliperenan, I will get right on that

Here you go @feliperenan. I've added all the information in the README

Hi @franks921

After some investigation I figured out that it only works with numeric inputs which makes sense for me. So in your case, all you need to do is providing as: :integer option to your input to get it working from the wrapper.

We could improve the documentation being more clear about it somewhere. Feel free to open a pull-request for that :wink:. For now, I'm going to close this one since it seems working as expected.

Thanks for the issue and reproduced app, it helped a lot to understand what's going on :muscle:
