Let's Simplify Magento

In magento 2, the theme folder is inside the module. We don't have to write the code in separate theme folder location outside the core module files folder.

In magento 2, events have been changed from events tag in config.xml to events.xml file in etc folder or etc/adminhtml/ folder or etc/frontend/ folder. You can find the sample code in the git repo .

In magento 1, we had sql directory for adding or updating the tables in database. In magento 2, it is changed to Setup folder. The folder contains all the sql changes that need to be pushed to database on the module install. You can find the sample code in the git repo .

In magento 2, the creation of module has changed completely. We will go through how to create a module. Like earlier magento, we do not need to put our module files in different folders for code, theme, skin, etc. All, the codes related to the module should be inside one main folder. You can find the sample code in the git repo .

In default magento, on click of "Apply rules" in catalog price rules (Promotions > Catalog Price Rules), it get the products for all the active rules and add the data in a separate table. If there are more than five active rules, then lots of data have to be created and the process takes a lot of time. If we have to create a new rule, the save and apply will re-calculate for all the active rules.

If you have the attribute code and the option value id for the data, then we can get the text value for the option by the below code. The below code is for product, you can use the same logic to get the data for other eav resource models like customer, category, etc.

We always require the attribute data via attribute code. Below is the code to get the product attribute data from the attribute code. It can used to get the attribute data from the code, without always trying to load the attribute model. public function getAttribute($code) { $this->getAttributes(); if (isset($this->_attributes[$code])) { return $this->_attributes[$code]; } return null; } public function getAttributes() { if (is_null($this->_attributes)) { $this->_attributes = Mage::getResourceSingleton("catalog/product") ->loadAllAttributes() ->getAttributesByCode(); } return $this->_attributes; }
