RoR How to properly set fields_for? - ruby-on-rails

Question

I've got this whole surveys thing:
Survey.rb

belongs_to :filled_survey
belongs_to :question
belongs_to :option, class_name: 'QuestionOption', optional: true
validates :content, presence: true, length: { minimum: 1 }, on: :update
validate :content, :validate_question_rules, on: :update
end
And view:
/ Body
.w-full.flex-grow.overflow-y-auto
/ Surveys questions forms
= form_for #selected, url: update_filled_survey_path(#selected.id), html: { data: { 'participant-target' => "#{#selected.id}_form" } } do |form|
= form.hidden_field :survey_id
- #selected.questions.includes(:question_options).each do |question|
.rounded-md.bg-gray-100.opacity-75.flex.items-center.justify-between.mb-2.p-2.relative
%span.flex-grow
= render "components/inputs/#{question.question_type}", question: question, form: form
.flex.justify-center.bg-gray-100.rounded-md.cursor-pointer.my-3
%button.w-full.px-6.py-2.bg-green-200.rounded-md.cursor-pointer.hover:bg-green-300{'data-action' => 'click->participant#updateSurvey', 'data-filled' => #selected.id } #{t('views.participant_portal.surveys.complete')}
Partial(for single type question):
.input_group.flex.flex-col.justify-start
%label.text-gray-700.text-md.font-bold
= question.title
- if question.description
%label.text-gray-600.text-sm #{question.description}
.p-4
= form.fields_for question.question_options do |question_form|
= question_form.collection_select(:option_id, question.question_options, :id, :display, { selected: question.question_options.option_id, include_blank: false }, { id: question.id, name: "#{question.id}_answer", class: 'bg-transparent mx-2'})
JS controller (stimulus JS):
updateSurvey (e) {
document.getElementsByTagName('form')[0].submit()
}
Controller
before_action :set_filled, only: %i[fill_survey]
def set_filled
if current_user.profile.active_study && current_user.profile.paid?
#surveys = current_user.profile.active_study.surveys.select(&:medical).map do |survey|
FilledSurvey.includes.find_or_create_by(survey: survey, user: current_user)
end.reject(&:done?)
elsif current_user.profile.active_study && current_user.profile.approved?
#surveys = current_user.profile.active_study.surveys.select(&:medical?).map do |survey|
FilledSurvey.find_or_create_by(survey: survey, user_id: current_user.id,
created_at: FilledSurvey.this_month)
end.reject(&:done?)
elsif action_name == 'law_quiz'
#surveys = current_user.profile.active_study.surveys.select(&:law?).map do |survey|
FilledSurvey.find_or_create_by(survey: survey, user_id: current_user.id,

end.reject(&:done?)
end
end
def fill_survey
set_meta_tags(title: t('page_title.participant_portal.fill_survey'))
aasm_state = current_user.profile.aasm_state
redirect_to authenticated_root_path unless %w[paid approved].include?(aasm_state) &&
!#surveys.empty?
#active_study = current_user.profile.active_study
#selected = params[:id] ? FilledSurvey.find(params[:id]) : #surveys.first
# #answers = #selected.survey.questions.map do |question|
# Answer.find_or_create_by(question_id: question.id, filled_survey_id: #selected.id)
# end
# #answers.sort_by { |answer| answer.question.order }
end
What I wanted to do:
Submit all forms with one button
Get ID of QuestionOption that I select for each question
Create Answer for each Question based on QuestionOption
What I get:
"undefined method `option_id' for #<ActiveRecord::Associations::CollectionProxy [#<QuestionOption id: 328, name:(...)"
Can someone explain how to make it works? I want to understand what's wrong with this code, so I can implement this right way
