Создание модуля для Magento – часть 1
Популярность Magento постоянно растет. Появляется множество новых интеренет-магазинов, написанных на этом замечательном движке.
К сожалению, информации для разработчиков маловато, поэтому, будем исправлять ситуацию 🙂
В мои планы входит написание нескольких статей о том, как создать модуль для Magento, на примере модуля блога.
Изначально ограничимся минимальным функционалом: напишем административную часть модуля, при помощи которой можно будет управлять статьями блога в админке.
Модуль создается в отдельном namespace. Обычно, namespace – это название компании разработчика модуля.
В данной статье я буду создавать модуль блога для Magento в своем неймспейсе Snowcore.
Название модуля не должно содержать символов подчеркивания. Все custom модули создаются в директории /app/code/local
Мой модуль будет называться Snowcore_Blog
Перейдем непосредственно к делу. Что же нужно для написания модуля для Magento?
Отключение кеша Magento
Первым делом отключаем cache в Magento, иначе не сможем увидеть своих изменений 🙂 Отключить кеширование можно в админке: System – Cache Management – в первой вкладке Cache Control изменяем параметр All Cache на Disable, жмем Save cache settings
Создание структуры директорий
В папке модуля создаем следующую структуру:
/app/code/local/Snowcore/Blog/
Block
controllers
etc
Helper
Model
sql
Добавляем директорию для шаблонов:
/app/design/frontend/default/default/template/blog
(здесь первый default – это интерфейс, второй default – тема)
Подключение модуля
Для подключения модуля нужно создать XML файл конфигурации:
/app/etc/modules/Snowcore_Blog.xml

На данном этапе Magento уже знает о нашем модуле. Включить или выключить его можно при помощи изменения параметра
Управлять модулем также можно через админку: System -> Configuration -> Advanced.
Значение local для узла
Создание XML конфигурации для модуля
Создаем новый xml файл: /app/code/local/Snowcore/Blog/etc/config.xml

Этот хелпер нужен для того, чтобы работала система переводов.
На данном этапе у нас должен появиться новый пункт в главном меню админки:
Сразу создадим хелпер для статей:

Создание моделей
Magento использует “тонкие” модели. Есть два типа моделей:
- Обычная модель: отвечает за бизнес-логику
- Ресурс-модель, которая работает с базой
Для начала нам понадобятся модели для статей.
Создаем обычную модель:

Второй параметр метода _init это первичный ключ таблицы articles.
Создаем коллекцию для статей:
/app/code/local/Snowcore/Blog/Model/Mysql4/Article/Collection.php
С коллекциями работает grid, который показывает список сущностей (статей).

SQL установщик для модуля
Установка модуля (создание таблиц в базе) происходит автоматически.
Здесь главное правильно указать версию для модуля, она должна совпадать с версией, которая назначена в XML конфигурации.

Установка модуля (создание необходимых таблиц) происходит автоматически – при обращении к любой странице. Если возникают проблемы с установкой модуля (таблицы не создались) – посмотрите в базе таблицу core_resource, там должна быть запись со значением code = blog_setup. Удалите запись, модуль переустановится.
Создание Layout модуля
Создаем новый XML:
/app/design/adminhtml/default/default/layout/blog.xml

Создание блоков
Блоки отвечают за отображение модуля. В рамках первой статьи создаем блоки для админки.
Изначально нам понадобится блок для отображения списка существующих записей – grid.
Создаем контейнер для grid:
/app/code/local/Snowcore/Blog/Block/Adminhtml/Article.php

Кратко о гриде:
- В конструкторе мы задаем параметры сортировки
- В методе _prepareCollection указывается, с какой коллекцией будет работать grid
- Метод _prepareColumns позволяет определить, какие колонки будут отображаться в таблице сущностей
- Метод getRowUrl определяет формат ссылки для перехода на форму редактирования (при клике на определенную строку)
Cоздание контроллера
В рамках этой статьи у контроллера будет только index action (отображение таблицы со статьями)

Наш контроллер пока содержит index действие, в котором происходит инициализация layout и breadcrumbs. На данном этапе на странице Manage Articles отображается содержимое таблицы статей. Таблица пока пустая, но для проверки работоспособности грида, можете добавить вручную пару записей в базу.
Mage_Adminhtml_Block_Widget_Grid предоставляет возможность использования фильтра и сортировки списка по заданным полям.
В итоге мы получили рабочую таблицу с возможностью фильтрации и сортировки данных. В следующей статье мы сделаем возможность управления записями таблицы.
See you soon 😉
