How to Get Current DateTime of Store

The current date and time according to the timezone of store can be found using below code snippet.

In your class file inject instance of 'Timezone' as below.

protected $_timezone;

public function __construct(

....

\Magento\Framework\Stdlib\DateTime\TimezoneInterface $timezone,

....

) {

....

$this->_timezone = $timezone;

....

}

Now, in your method, you can find the current date and time of store using below statement.

$this->_timezone->date()->format('Y-m-d H:i:s');

Incorrect dependency in class already exists in context object

Magento 2 classes have dependency injection in constructor method. One special object which is there is context.

The context object further provides many other objects. Apparently, if you have injected context object in your module's class which may further inheriting some Magento 2 class, you may not need to inject some objects which are already being provided by context object. This mechanism makes sure, your system does not end up with many duplicate objects occupying memory and leads to poor performance.

When your Magento 2 shop runs with developer mode, the system does not report any issue. But when you switch the mode to production, it reports the error.
Also, when you run php bin/magento setup:di:compile command, the system reports the error.

Now, to the point, how to solve the error which looks like something below, the class name may be different.
Errors during compilation:
Helper\Data
Incorrect dependency in class Helper\Data in vendor/xxx/Helper/Data.php
\Magento\Framework\SOME\CLASS already exists in context object

Total Errors Count: x.

As we have learned above, the object is already being provided by the context object. So, it does not need to be injected, instead retrieved from context object.
Step 1: Remove the object from your constructor which was reported as already exists.
Step 2: Assign your class property by retrieving the object from context object.
For example, if your constructor method looks like below and reported error for class ScopeConfigInterface.

public function __construct(
\Magento\Framework\App\Helper\Context $context,
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
) {
$this->_scopeConfig = $scopeConfig;

parent::__construct($context);

}

The rectification will look like below.

   public function __construct(
\Magento\Framework\App\Helper\Context $context
) {
$this->_scopeConfig = $context->getScopeConfig();

parent::__construct($context);

}

Hope, this will help you to rectify the error appeared while running php bin/magento setup:di:compile command.

Errors during compilation:
Incorrect dependency in class x.php
some class already exists in context object
Total Errors Count: x

Why Magento 2 extensions are priced too high

Magento 2 is a new technology stack which can withstand to the new technology trends in web development. The use of cutting edge stack enables the Magento 2 software even more flexible, adaptable and scalable.

Magento 2 was announced to be “stable” during late 2015. However, it was full of bugs and incurred development cost. Then, Magento 2 has started releasing in two channels – 2.0.x and 2.1.x and there are very less chances of a module which was developed for 2.0.x work in 2.1.x. So, the development companies had to put extra efforts in development and testing for each channel and since Magento introduces many changes from version to version the extensions need to be maintained at high cost.

The development companies constantly tries to improve their product. But they have to pass through a long process of approval if they are selling it on marketplace of Magento. If in between some customer purchases the extension, the possibility of support will be there if any needed corrections are identified after getting the extension live.

Putting all the above together, the development companies are spending a lot of efforts in developing and maintaining the extensions and as a consequence the cost of the extensions rise.

You may find Magento 2 extensions at cheap rates.

Unable to load theme magento2

If you are one of those who are facing issue "Unable to load theme" while registering a new Magento theme.

You might be experiencing below errors even after creating a new Magento2 theme and properly placing all the necessary files registration.php and theme.xml.

'theme' table in database does not show your theme entry.
Content > Design > Theme in admin panel does not show your newly created theme entry.
setup:static-content:deploy command stuck while processing your theme.

Login as Magento file system owner.
Navigate to Magento2 installation location.
Run below commands.
chown -R :nginx .
(replace 'nginx' by your web server user group name)

find . -type d -exec chmod 770 {} \; && find . -type f -exec chmod 660 {} \; && chmod u+x bin/magento

The theme registration issue should be resolved when you access your Magento2 store and run static-content:deploy command. "Unable to load theme" should be gone from console now.

Magento 2: grunt refresh, grunt documentation commands are not working

jit-grunt: Plugin for the "xxxx" task not found.
If you have installed the plugin already, please setting the static mapping.
See https://github.com/shootaroo/jit-grunt#static-mappings

After installing Magento 2 and the node modules including grunt if you are facing error like above while executing the refresh and documentation tasks you may need to update your Gruntfile.js. (Below is the working solution in Magento 2 beta at the time of writing Oct 16, 2015)

For static mapping below code should be entered just below 'use strict'; statement. So, the top of your Gruntfile.js should look like.

..........

module.exports = function (grunt) {
    'use strict';

    require('jit-grunt')(grunt, {
        refresh: 'refresh',
        usebanner: 'grunt-banner'
    });

    var _ = require('underscore'),
        path = require('path'),
        configDir = './dev/tools/grunt/configs',
        taskDir = './dev/tools/grunt/tasks';
..........

It should resolve the issue in your Magento 2 beta version installation ..
jit-grunt: Plugin for the "xxxx" task not found.
If you have installed the plugin already, please setting the static mapping.

Magento 2: How to do Index Management

In Magento 2 there is no reindex button or separate reindex link to index the indices as of writing this article.
So, how can we reindex the data in Magento 2?

Well, Magento 2 comes with great CLI applications that helps us to run many tasks quickly via command line.

To reindex the indexes in Magento 2,
In command prompt navigate to the Magento 2 installation directory and then run below command.
php bin/magento indexer:reindex

If php CLI is not in your system path, one of below commands may invoke PHP CLI for you.
/usr/bin/php
/bin/php
/usr/sbin/php
/sbin/php
/usr/local/bin/php

Windows users can run
PATH_TO_php.exe bin\magento indexer:reindex in command prompt.

Magento 2: No CSS displayed after installation

After installing Magento 2.0 framework many of us face the issue of no formatting on frontend or admin panel.
After installation there is possibility of the less files are not yet compiled and the Workflow type is server side i.e the less files should be compiled on server and your mode of project is 'developer'.
The setting is available in admin panel at Stores > Configuration > Advanced > Developer > Frontend development workflow > Workflow type.

There are two solutions.

> Set the Workflow type to "Client Side Less Compilation" but this will slow down your frontend as the less files will be compiled in browser's Javascript engine.

> The other way is to compile the files manually using the "grunt" (http://gruntjs.com/) tasks available in Magento 2. Below are the steps to follow.

1) Assuming that you have already installed nodejs (https://nodejs.org/) on the machine where the web server and your Magento 2 installation is located.
2) In the node command prompt, navigate to Magento 2 root directory and run following command to install the grunt plugin.
npm install grunt
3) The above will install the grunt npm package and you'd be now able to run grunt tasks in Magento 2 installation path.
4) Once the grunt plugin installed, run following command. You'd need your PHP process running as less compilation is executed by PHP.
grunt refresh
The above command will compile less files in all of the themes available in current installation.
It will take around 3 - 4 minutes depending on the complexity of theme. You can optionally run the following command to compile particular theme only.
grunt exec:<YOUR THEME NAME>

When the process completes successfully, you'll be able to review the frontend and admin panel with CSS formatting working.
