Страница загружает ненужные запросы Ruby On Rails

/ 02 ноября 2018

У меня странная проблема, каждая страница моего сайта, содержащая запросы к базе данных, загружает некоторые дополнительные элементы. У меня никогда раньше не было этой проблемы, я пытался проверить все контроллеры, но проблем не нашел Вот пример вывода при загрузке (или обновлении) home page : 

=> Booting Puma
=> Rails 5.1.6 application starting in development
=> Run `rails server -h` for more startup options
Puma starting in single mode...

* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://0.0.0.0:3000

Мой статический контроллер:

  def home
    @catalogs = Catalog.all.where(open: true).order('created_at ASC').limit(6)
    # @products = Product.all.includes(:catalog, :category).where(open: true).order('created_at DESC').take(8)
  end

  def about
    @catalogs = Catalog.all.where(open: true)
    @categories = Category.all.where(open: true)
    @products = Product.all.where(open: true)
  end

  def download_pdf
    send_file "#{Rails.root}/app/assets/docs/1_s.pdf", type: "application/pdf", x_sendfile: true
  end
end

Примечание: у меня похожие проблемы с другими контроллерами

В начале я думал, что это сумка, потому что я не добавил никакого нового кода. Пожалуйста, дайте мне знать, если вам нужно больше кода от контроллеров. Большое спасибо за ваше время и помощь.

UPDATE

У меня есть 3 модели: каталог, категория и продукты.

Каталожная модель: 

class Catalog < ApplicationRecord
    extend FriendlyId
    friendly_id :name, use: [:slugged, :history]

    mount_uploader :photo, PhotoUploader
    has_many :categories, dependent: :delete_all
    has_many :products, :through => :categories, :source => :catalog, dependent: :delete_all

    # Important fields
    validates_presence_of :name
end

Категория модели: 

class Category < ApplicationRecord
    extend FriendlyId
    friendly_id :name, use: [:slugged, :history]

    belongs_to :catalog, :foreign_key => 'catalog_id'
    has_many :products, dependent: :delete_all

    # Important fields
    validates_presence_of :name

    def self.active
      where(status: 1)
    end
end

Модель товара: 

class Product < ApplicationRecord
    extend FriendlyId
    friendly_id :name, use: [:slugged, :history]

    mount_uploader :photo, PhotoUploader
    belongs_to :catalog, :foreign_key => 'catalog_id'
    belongs_to :category, :foreign_key => 'category_id'

    # Important fields
    validates_presence_of :name
end

Ожидаемый вывод в консоли:

Домашняя страница HTML (HAML), однако следует отметить, что у меня возникает аналогичная проблема с другими страницами, к которым требуются запросы (например, страницы каталога каталога):

Хорошо, я не понял ход проблемы, но решил воссоздать базу данных:

rake db:drop db:create db:migrate

Исправлена ​​проблема ..

Целая куча вещей и трудно помочь без фактического запуска кода.

Прежде всего, ознакомьтесь с хорошей практикой в ​​отношении именования вещей. @catalogs.each do |pc| - это нет-нет, и оно должно быть @catalogs.each do |catalog|.

if !@products.empty? и @product.count, эти запускают два запроса, и я рекомендую записать счет в @products_count и заменить это пустое? с @product_count > 0

Используйте scope в модели для замены таких вещей, как .where(open: true)

В @products.includes(:catalog, :category) вы можете удалить catalog, поскольку вы уже просматриваете продукты по каталогу и можете использовать pc (или, как я рекомендовал выше: catalog) вместо product.catalog

Если catalog_category_product_url не использует ничего необычного, а только идентификаторы (например, catalog/5/category/2/product/23), тогда вы можете сделать catalog_category_product_url(product.catalog_id, product.category_id, product), чтобы предотвратить несколько дополнительных запросов (особенно если вы забыли использовать готовую загрузку или не хотите загрузить большой кусок данных из БД).
