Using non-standard primary key with Eloquent relations (Laravel 5)

In my experience of using PHP web frameworks, Laravel is one of my favorites. Laravel helps faster development as well as much more simple to work with and feel very familiar if you are coming from frameworks such as Symfony.

The Eloquent ORM is one of the many things, that makes Laravel smarter. It makes simple for many developers to play with database. All these ease come with the standard pattern which recommended. If for some reason, you need a customized database design, it comes with a small cost, where you need to setup few things (Yet, it is far simple than many other frameworks do).

On one of my past works, I was having some difficulties in working with relations in Eloquent. It was because, I was using a non-standard primary key and column type.

Below is the model of my tables.

profiles-device-models
The table, ‘device_models‘ is using a primary key that is type of ‘varchar’. In standard Eloquent way of relation, it is expecting to be an ‘increment’ column type which will end up in ‘unsigned int’ in MySQL. To make this primary key compatible with Eloquent relation, you need to set additional three fields in class definitions.

  1. protected $primaryKey = ‘device_model’;
  2. public $incrementing = false;
  3. public $keyType = ‘string’;

These additional fields tell Eloquent that, the standard way of implementation is changed a bit, and please use these values instead. In addition to these properties, you need to pass the primary key field name in the function which creates the actual relation. Or else Eloquent will automatically adds _id

The complete migration and Eloquent model are presented below.

Resolve Google play service issue in Samsung Galaxy Note 3

Resolve ‘Your device is not compatible with this version’ issue of Samsung Galaxy Note 3 while installing Google play service on Lollypop update

Google-Play-Services-Guide

It looks all the forums are flooded with this question. It usually happens after factory reset of a Samsung Galaxy Note 3 after Lollipop update. Same like to many other, it happned to me as well. It might be a Samsung bug as it seems to be reported only from Galaxy Note 3. I am sorry for blamming Google at the begining. 😀

The simplest solution is to download the Google play service APK from and external source and install it manually. To install it ..

  1. Download the Latest APK v9.2.56 from an external link.
  2. Enable “Unknown sources” from ( Setting -> Security -> Unknown sources ) your Note 3
  3. Copy the downloaded APK to your mobile storage.
  4. Open and Install.

Done !.

Using PDO::fetchAll – Examples with codes and output results

PHP Data Objects (PDO) as an abstraction layer used for accessing databases. It makes life easier while working with databases oriented applications.
There are several fetch modes available with the library which help us through the development and it would reduce a lot of custom coding if we know exactly how to use them.

We will discuss some of them.

  • PDO::FETCH_COLUMN
  • PDO::FETCH_ASSOC
  • PDO::FETCH_BOTH
  • PDO::FETCH_KEY_PAIR
  • PDO::FETCH_GROUP
  • PDO::FETCH_CLASS
(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)

PDOStatement::fetchAll — Returns an array containing all of the result set rows

 

 

PDO::FETCH_COLUMN

Returns the indicated 0-indexed column.

Example result:

Sample code:

 

PDO::FETCH_ASSOC

returns an array indexed by column name as returned in your result set

Example result:

Sample code:

 

PDO::FETCH_BOTH

Specifies that the fetch method shall return each row as an array indexed by both column name and number as returned in the corresponding result set, starting at column 0.

Example result:

Sample code:

 

PDO::FETCH_KEY_PAIR

Fetch a two-column result into an array where the first column is a key and the second column is the value

Example result:

Sample code:

 

PDO::FETCH_GROUP

Groups the result by the first column.

Example result:

Sample code:

 

PDO::FETCH_CLASS

Specifies that the fetch method shall return a new instance of the requested class, mapping the columns to named properties in the class.

Sample code:

Example result:

Installing Kubuntu Desktop (KDE) on Ubuntu 14.04LTS

KDE is probably the best looking environment around, and it has a very cool widget-based desktop built in to the environment. Its menus are set up very much like Windows, with one main menu located in the bottom left corner of the taskbar from which you launch apps and view settings.

Installing KDE

The following lines explain how to install KDE desktop on Ubuntu Linux 14.04 LTS.

Creating a VLAN with Oracle virtual box

Same like many other Vms, Oracle virtual box also supports creating a VLAN. To do this first we need to understand the different types of networ types in Virtual Box.

  • Not Attached
  • Network Address Translation (NAT)
  • NAT Network
  • Bridge Network
  • Internal Network
  • Host Only Network
  • Generic Network

I do not want to repeat the details of all about network types. If  you are concern about it, please refer to this link ==>> (6.2. Introduction to networking modes)

Each different types os networking methods can be used to achieve different kinds of tasks. In our case, we would use “Internal Network”. This will help us create VLANs by names.

 

Steps :

  1. Go to settings, Click on “network” tab
  2. Click on “Enable Network Adapter” in one of the adapter tab.
  3. In “Attached to” select box, choose “Internal Network”
  4. For the name input box, provide a VLAN name if you do not have already one. It is your choice.

 

The below screenshot will describe you more.
