simple_fields_for простой формы дублирует мою запись

Question

У меня проблема с simple_form.У меня есть модель Order, которая может иметь много texts.Модель Text может иметь текстовое содержимое ИЛИ прикрепленного документа.

Я имею в виду обновить @order и добавить столько текстов, сколько хочет пользователь.В представлении моя форма визуализируется, а затем один simple_fields_for :texts в двух разных частях:

show.slim:

.card
  = simple_nested_form_for(@order, url: steps_order_texts_url, html: { id: 'order-form' }) do |f|
    .card-body
      .row.mx-1
        .col
          = render('filedownloader', f: f)
          = render('copytext', f: f)

    .card-footer.fast-card-footer
        = button_tag(type: 'submit', class: 'btn btn-primary btn-lg fast-btn', data: { disable_with: 'Please wait...' }) do
          | Next
          =< fa_icon('far', 'angle-right')

_filedownloader.slim:

.text-upload-content-wrapper
  .filedownloader-wrapper-bottom
    - secureId = SecureRandom.hex
    .d-flex.flex-column.caption id="#{secureId}"
      .d-flex.align-items-center
        label.btn.btn-lg.btn-primary-dark.text-nowrap.filedownloader-custom-button for="text_document_#{secureId}"
          | Choose a file
        = f.simple_fields_for(:texts, @order.texts.build) do |ff|
          = ff.input(\
            :document,
            label: false,
            error: false,
            input_html: { hidden: true,
                          id: "text_document_#{secureId}",
                          direct_upload: true)

  .filedownloader-divider

  .filedownloader-wrapper-footer
    .d-inline-flex.align-items-center
      span.filedownloader-addfile
        = fa_icon('fal', 'plus-circle')
        | Add a file

_copytext.slim:

.text-copy-content-wrapper
  .filedownloader-copy-wrapper-bottom
    = hidden_field_tag(:id, @order.id)
    #recurring-texts
      = f.simple_fields_for(:texts) do |ff|
        - unless ff.object.persisted? && ff.object.content.blank?
          .order-form-text
            = ff.input( \
                :content,
                input_html: { \
                class: 'form-control order-form-text-description',
                rows: 4,},
                required: true)

            .d-flex.justify-content-end
              = ff.link_to_remove( \
              t('orders.remove_text'),
              class: 'btn btn-danger btn-sm',
              data: { confirm: "Are you sure?" })

    = f.link_to_add( \
      "#{fa_icon('far', 'plus-circle')} Add a text".html_safe,
      :texts,
      data: { target: '#recurring-texts' },
      class: 'btn btn-primary-dark btn-lg')

Проблема заключается в том, что при отправке формы мои записи дублируются.Я думал, что это потому, что есть два simple_fields_for :texts, но даже с одним, тексты дублируются.Кроме того, если я пытаюсь редактировать текст, Rails пытается создать текст с тем же идентификатором (поэтому возникает ошибка) вместо обновления записи (конечно, id разрешено в texts_attributes).

Это мои журналы, когда я создаю ОДИН текст, вы можете видеть, что ActiveRecord вставляет два текста:

Мы можем видеть это:

Там есть толькоодин текст, так что я действительно не знаю, в чем проблема ... Есть идеи?

Большое спасибо

РЕДАКТИРОВАТЬ 2: Я добавил бибаг до обновления, затем я проверил (на всякий случай) order_params:

<ActionController::Parameters {"texts_attributes"=><ActionController::Parameters {"1"=><ActionController::Parameters {"content"=>"Hello world", "_destroy"=>"false"} permitted: true>} permitted: true>} permitted: true>

Хорошо, есть только один текст.Сейчас:

order = Order.new(order_params)
order.texts.size
#=> 2
order.pluck(:content)
#=> ['Hello world', 'Hello world']

... WTF?

РЕШЕНИЕ: Хорошо, плохо.В моей модели Order у меня было reject_if на моем accepts_nested_attributes_for.В этом reject_if я строил текст с атрибутами для проверки определенных вещей ... Но после этого построенный текст не был уничтожен, поэтому он был добавлен к текстам заказа.
