Algolia 1.6.1 or higher automatically update the product index

Algolia 1.6.1 or higher comes with a new feature that automatically updates your product index, every time you save a category. The disadvantage is that it will also update the product index, even if you just change an attribute which has nothing to do with URL rewrites or something else that can break search results. This can increase your indexing operations rapidly, therefore your monthly bills from Algolia as well.

To prevent unnecessary indexing, you should disable the new feature in System > Configuration > Algolia Search 1.x > Advanced > Update product on category products update and manage indexing manually with System > Index Management or simply with cron jobs.

Nginx Docker Container and getpwnam(“www-data”) problem

I am using nginx:1.10.1-alpine to run Nginx as a docker container. Today I have replaced the Nginx container and always got the status Restarting (1) Less than a second ago after starting the container.

CONTAINER ID        IMAGE                          COMMAND                  CREATED             STATUS                                  PORTS                         NAMES

With the command docker logs nginx I got the following error logs.

nginx: [emerg] getpwnam("www-data") failed in /etc/nginx/nginx.conf:1

The error message basically means that the user www-data which I have defined in /etc/nginx/nginx.conf doesn’t exists in /etc/passwd. That makes sense, because nginx:1.10.1-alpine comes with a minimal setup. I my case I need the user www-data for other linked php-fpm containers. To fix the problem I just added the missing user during the container build.

FROM nginx:1.10.1-alpine
RUN addgroup -g 1000 -S www-data \
 && adduser -u 1000 -D -S -G www-data www-data

FROM nginx:1.10.1-alpine

RUN addgroup -g 1000 -S www-data \

&& adduser -u 1000 -D -S -G www-data www-data

Voilà.

Programmatically Create a Gift Card for Magestore Gift Card Module

This is a quick example of how you can programmatically create a code for Magestore’s Gift Card module.

1. Create the Gift Card

$data = array(
    // Valid price format without currency code
    'balance' => $input['giftcard_balance'],

    // The currency code such as $ or €
    'currency' => Mage::app()->getStore()->getCurrentCurrencyCode(),

    // Please find all available statuses in the Magestore > Gift Card module
    'status' => 2,

    // Remove the line to set no expire date
    'expired_at' => strtotime('+1 month'),

    'customer_id' => $customer->getId(),
    'customer_name' => $customer->getFirstname(),
    'customer_email' => $customer->getEmail(),
    'recipient_name' => 'Recipient Name',
    'recipient_email' => 'recipient@email.tld',

    'extra_content' => $this->__('Created by module X')
);

$giftvoucher = Mage::getModel('giftvoucher/giftvoucher')
->setData($data)
->setIncludeHistory(true)
->save();

$data = array(

// Valid price format without currency code

'balance' => $input['giftcard_balance'],

// The currency code such as $ or €

'currency' => Mage::app()->getStore()->getCurrentCurrencyCode(),

// Please find all available statuses in the Magestore > Gift Card module

'status' => 2,

// Remove the line to set no expire date

'expired_at' => strtotime('+1 month'),

'customer_id' => $customer->getId(),

'customer_name' => $customer->getFirstname(),

'customer_email' => $customer->getEmail(),

'recipient_name' => 'Recipient Name',

'recipient_email' => 'recipient@email.tld',

'extra_content' => $this->__('Created by module X')

);

$giftvoucher = Mage::getModel('giftvoucher/giftvoucher')

->setData($data)

->setIncludeHistory(true)

->save();

2. Link the Gift Card to a Customer

In order to be able to see the Gift Card in My Account > Gift Card you need to create a reference between Gift Card and a customer id. This is something you can do right after the Gift Voucher was successfully created.

$customervoucher = Mage::getModel('giftvoucher/customervoucher')
->setCustomerId($customer->getId())
->setVoucherId($giftvoucher->getId())
->setAddedDate(now())
->save();

$customervoucher = Mage::getModel('giftvoucher/customervoucher')

->setCustomerId($customer->getId())

->setVoucherId($giftvoucher->getId())

->setAddedDate(now())

->save();
