has_and_belongs_to_many не регистрируется через collection_check_boxes в Rails 5.2

Question

Я пытаюсь создать в своем приложении функцию, которая позволит вам создать occasion (то есть Рождество 2018 года), а затем выбрать из множества people, какие из них вам понадобятся, чтобы купить подарки для этого occasion.

Прямо сейчас у меня есть has_and_belongs_to_many вот так:

  create_table "occasions", force: :cascade do |t|
    t.integer "person_id"
    t.integer "user_id"
    t.string "name"
    t.date "date"
    t.text "notes"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["person_id"], name: "index_occasions_on_person_id"
    t.index ["user_id"], name: "index_occasions_on_user_id"
  end

  create_table "occasions_people", id: false, force: :cascade do |t|
    t.integer "occasion_id", null: false
    t.integer "person_id", null: false
  end

  create_table "people", force: :cascade do |t|
    t.string "relationship"
    t.string "first_name"
    t.string "middle_name"
    t.string "last_name"
    t.date "birthday"
    t.date "anniversary"
    t.date "other"
    t.string "other_date_name"
    t.text "notes"
    t.integer "user_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "group"
    t.integer "occasions_id"
    t.index ["occasions_id"], name: "index_people_on_occasions_id"
    t.index ["user_id"], name: "index_people_on_user_id"
  end

Мои отношения заложены как в моей person.rb модели:

class Person < ApplicationRecord
  belongs_to :user
  has_and_belongs_to_many :occasions

  def full_name
    "#{last_name}, #{first_name}"
  end
end

, так и в моей occasion.rbмодель:

class Occasion < ApplicationRecord
  has_and_belongs_to_many :people
  belongs_to :user
end

У меня есть правильные (я думаю) параметры в моих people_controller:

def person_params
  params.require(:person).permit(:relationship, :first_name, :middle_name, :last_name, :birthday, :anniversary, :other, :other_date_name, :notes, :group, :user_id, :occasion_id)
end

И в моих occasions_controller:

def occasion_params
  params.require(:occasion).permit(:person_id, :user_id, :name, :date, :notes)
end

В моей форме есть следующее, чтобы создать новый occasion как компромисс между этой документацией и этим SO исправлением:

<%= simple_form_for(@occasion) do |f| %>
  <%= f.error_notification %>
  <%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>

  <div class="form-inputs">
    <div class="row">
      <div class="form-group col-sm-6 ">
        <%= f.input :name, required: true %>
      </div> <!-- col -->
      <div class="form-group col-sm-6">
        <%= f.label :date %>
        <input type="text" class="form-control datepicker" data-datepicker-holder="#dateHolder"/>
        <%= f.hidden_field :date, id: "dateHolder", class: "hiddenDateField" %>
      </div> <!-- col -->
    </div> <!-- row -->
    <div class="form-group">
      <%= f.label :notes %>
      <%= f.text_area :notes, class: "form-control" %>
    </div> <!-- col -->
    <div class="form-group collection-checkboxes">
      <%= f.label "Who do you need to shop for?" %><br />
      <%= f.collection_check_boxes(:people, Person.where(user_id: current_user.id).order("last_name ASC"), :id, :full_name) %>
    </div> <!-- col -->
  </div>

  <div class="form-actions text-center">
    <%= f.button :submit, class: "btn btn-outline-primary", style: "margin-bottom: 10px" %>
  </div>
<% end %>

Когда я пытаюсьсоздайте новый occasion, флажки отображаются так, как должны, но независимо от того, что отмечено, никакая ассоциация не зарегистрирована, и я получаю unpermitted parameter для :people:

Может кто-нибудь увидеть, чтоНужно изменить здесь, чтобы заставить его работать как задумано?Я новичок в ассоциациях HABTM.

Недопустимый параметр:: люди

Вам необходимо изменить

<%= f.collection_check_boxes(:people, Person.where(user_id: current_user.id).order("last_name ASC"), :id, :full_name) %>

на

<%= f.collection_check_boxes(:person_ids, Person.where(user_id: current_user.id).order("last_name ASC"), :id, :full_name) %>

И белый список person_ids вoccassion_params

def occasion_params
  params.require(:occasion).permit(:user_id, :name, :date, :notes, person_ids: [])
end

Для получения дополнительной информации см. collection_check_boxes

Обновление:

В habtm ассоциация, объединенная таблица хранит записи для f_keys.Тем не менее, вы должны удалить person_id из occasions и occasions_id из people таблиц.
