Laravel 4 and database seeding

I’ve been playing around with Laravel 4 for a few days now and have been very impressed. Once I figured outhow to install it, so far the learning curve from Codeigniter seems to be small. Right now I’m taking an existing project written with Codeigniter and creating a Laravel version for it. I got the configurations set up, now to move on to the database. The migration feature is great. I’ve been able to create my database and rollback with ease. The next step is to take data from an existing database and import it over. I could dump it into an SQL file and be done with it. But the source project is live and data changes. I’d like to use migration to get the latest data off the source.

The solution is to use Laravel’s seeding. Migration and seeding work with each other. Unfortunately, the sample code and demo I’ve seen so far uses arrays to populate (seed) the database. It’s a good sign though because all I have to do is query the existing database and populate an array with the resultset. The problem is how and what the syntax is. After a few hours of researching online and testing, I’ve got the solution.

Let’s say your source database is MySQL and you have a client table with client_id and client_name columns. On your Laravel project you have a clients table with id, client_name, created_at, and updated_at columns. Add a new connection to your /app/config/database.php. If you have multiple MySQL databases, it’s okay, just append 2… so you have a mysql and mysql2 connection. So your mysql array connection holds your Laravel database and mysql2 holds your database connection information where you’ll be getting data from.

Next edit the /app/database/seeds/DatabaseSeeder.php file. Here’s what I have.

class DatabaseSeeder extends Seeder {

	 * Run the database seeds.
	 * @return void
	public function run()



class ClientTableSeeder extends Seeder

	public function run()
                // truncate the table before inserting imported data

                // use mysql2 connection then query the database, then put resultset in array
		$clients = DB::connection('mysql2')->select('SELECT `client_id`, `client_name` FROM `client`');
		$now = date('Y-m-d H:i:s');

                // loop through the resultset and insert into laravel database
		foreach ($clients as $client)
				'id'			=> $client->client_id,
				'client_name' 	=> $client->client_name,
			    'created_at' 	=> $now,
			    'updated_at' 	=> $now

Installing Phalcon in Ubuntu

Phalcon is a PHP Framework I wanted to play with. I have recently switched one of my PC from Windows 8.1 to a Linux distro – for development and everyday use. Slowly but surely I’m finding alternative software and loving it. I’m only going to use Windows for gaming. For now, I will be using Ubuntu 14.04 LTS. The version of Phalcon for this post is 1.3.1.

There is a little guide that can be found on their website that helps install Phalcon, but just like Laravel’s instructions, it’s somewhat incomplete. Which is why, for Laravel, I had to post an add-on guide to their guide. If you follow that guide, you will first run into problems in the compilation section where they want you to run the install command. It will complain about pcre. You can read more about the error at The solution is also there.

Once you install libpcre3-dev, you can continue with the install. The next trouble you may run into is trying to load the phalcon extension. Again, the guide is a little vague with its instructions. The solution to this is found at

	Create phalcon.ini file in /etc/php5/apache2/conf.d/phalcon.ini add : in this file.

Hope this helps you. I get lost easily when I play with new things. If loaded correctly, you should see this section in your php.ini.


Creating a CakePHP environment using MAMP and OS X

This will show you how to create a CakePHP environment in MAMP on OS X. Here list of softwares used and their version.

  • OS X Leopard or Snow Leopard
  • MAMP version 1.91 (using PHP5.2.x)
  • CakePHP 1.2.8

You shouldn’t have to use MAMP 1.9.1. I have it working on version 1.8.x. You will need to change Apache’s port from 8888 to 80. Make sure there aren’t any other web servers running on the same port. Leave MySQL running on port 8889. We will be creating a /Applications/MAMP/conf/apache/sites file that will store your virtual sites. It isn’t necessary but it’s easier to manage new sites on a separate file. You will need to edit the /Applications/MAMP/conf/apache/httpd.conf file by adding the following lines of code.

# virtual hosts file
Include /Applications/MAMP/conf/apache/sites

This will tell Apache to check the new sites file for additional configurations. So now, whenever you need to add or create a new site, you will edit the sites file and add the following code.

<VirtualHost *:80>
DocumentRoot /Users/username/Sites/projectname
ServerName projectname.local

The value of DocumentRoot can be different. I just chose to put it in that folder. Now you will need to edit your /etc/hosts file by adding the following code.          projectname.local

Restart your MAMP server. Now unzip the CakePHP files into the projectname folder. You should now be able to view your new CakePHP site by directing your browser to http://projectname.local. This page will tell you that you need to change the default Security.Salt value. All you need to do is change at least one character and you will meet the requirement. You can also use Terminal to generate your own.

echo -n 'foobar' | openssl sha1

This will give you a 40 character string. You can use a mixture of upper and lower case on the letters. Copy and paste this value from Terminal to give a new Security.Salt value.

The next warning is your database. Rename the database file and edit it. Provide your database server information. Because MySQL in MAMP is using port 8889, you will have to edit the array and add the following.

'port' => '8889'

There are notes in this file to help you further with additional array elements.

To use Terminal with the cake command, you will have to edit you ~/.bash_login file and create aliases. Here is the code to add to your .bash_login file.

# php
alias php5="/Applications/MAMP/bin/php5.2/bin/php"

# cake for this project
alias cake="php5 /Users/username/Sites/projectname/cake/console/cake.php"

To apply

. ~/.bash_login

You should be able to run

cake help

If you get a permission denied error, give it executable access with this.

chmod +x /Applications/MAMP/bin/php5.2/bin/php

That’s it. You can now start baking in a development environment. I know I have skipped a few steps but I’m assuming you know the basic commands and configurations. If not, please feel free to comment and ask questions. I’m still new with the MVC framework and CakePHP so go easy on questions regarding those. I am learning, slowly… haha!

Still looking for fast web development techniques

I’ve been developing web sites for almost 10 years now. I’m still in search of a way to develop faster. I find myself doing things over and over again.

I use PHP as the programming language to develop the web apps with MySQL database. I started to look for different frameworks – but most use MVC and I don’t have time to learn it.

Some have suggested to do validation using MySQL. This helps a bit so I don’t have to write more PHP code to validate whether or not the record exists, foreign key constraints, etc. Plus it really is good practice to have these in place in the database layer.

Next I looked in to template engines to help with the layout of the site. It does help quite a bit but I’m still left with a lot of PHP code. I use Dreamweaver to write code and I used to use its automated code writing but I found it too messy and inefficient. Now I only use it because the FTP client is built in, has a file checkout system and in CS5 it can read included files so I have easy access to them. The error check is nice too. It catches many syntax errors right away. It can read used variables and be a part of the autocomplete feature.

I tried using existing systems like CMS or blogs (Joomla and WordPress). I figured I can create add-ons on top of an existing system. Joomla uses the MVC framework. WordPress on the other hand is easier to figure out how to build on top of it. Plus their documentation is really easy to follow. One of the limitations I found is the lack of access levels. Another is the pre-existing environment may not fit with a project since it’s so customized – better to be built from the ground up.

I’ve been peeking into the .NET framework off and on. I don’t primarily use Windows at all. I’m mostly on a Mac or using some sort of Linux flavor. I do have Windows7 running virtually on my MBP and iMac so I can play with it. I have played with Visual Studio and it felt easy to use plus it seemed to make developing quick. The drawbacks I’ve found are Windows hosting is more expensive than Linux hosting, IDEs are expensive and run mostly on Windows OS, and I don’t like creating online applications that can potentially only work with Internet Explorer (does not support web standards and only available on Windows OS).

Rails looks promising with the DRY (don’t repeat yourself) approach. I’ve tried to look into it and even bought some books and watched some screencasts. It’s a great language but I can’t seem to understand how to authenticate/authorize different users. They have many different plugins that I can use but each one uses their own way of doing it.

I guess I’ll keep looking. Either I’ll find time to learn MVC framework, get better at Rails, or someone will develop a new platform to speed up web development.
