Eloquent Geonames

A collection of Eloquent models and Commands to get all the power of GeoNames in Laravel 4.

Installation

Add ipalaus/geonames as a requirement to composer.json:

{
    "require": {
        "ipalaus/geonames": "1.0.*"
    }
}

Update your packages with composer update or install with composer install.

Once you have installed the dependency, you need to register geonames in Laravel. Open your app/config/app.php and add the next provider to your providers array:

'Ipalaus\Geonames\GeonamesServiceProvider'

If you run now php artisan you should see a new namespace geonames with a few commands related to the package. In order to proceed with the install, run the next command:

$ php artisan geonames:install

This will publish the config file to app/config/packages/ipalaus/geonames/config.php and the migrations to your app/database/migrations directory. To be able to control what's going on, we recommend you to manually trigger php artisan migrate.

Artisan Commands

Import

The import command downloads the needed files (configurable in the config file) and run a seeder for each of them. A few options are provided:

--country=XX: downloads the specific country (ie. US, ES, FR...)
--development: downloads a smaller names file (~10MB) very useful for development environments.
--fetch-only: only fetch the files but won't run the seeder. If you want to download the files and then be able to regenerate the tables while offline.
--wipe-files: forces a delete of the old files.

$ php artisan geonames:import [--country="..."] [--development] [--fetch-only] [--wipe-files]

Importing a production database can take a while. Main file is ~1GB and the seeder has to insert ~6M rows while creating indexes for some fields. In development environments, I highly recommend to use the --development option and keep complete imports to production. The final table sizes can also affect your local MySQL instance.

Install

Publish the package's config and run the needed migrations. You can force the config publishing with the --force option.

$ php artisan geonames:install [-f|--force]

Seed

The is called by the geonames:import command. It extends the Laravel's db:seed but add to extra options: path and country. This is due to the size of the files to import and the queries that we have to run, geonames:import creates a new Symfony\Component\Process\Process for each seeder.

You shouldn't need to call this command directly.

Truncate

Do you want to truncate the table and start from scratch? Run:

$ php artisan geonames:truncate

Eloquent Models

Continent

Relationships:
hasMany countries

Country

Relationships:
belongsTo continent
hasMany names

Name

Relationships:
belongsTo country, eager loaded on every request

... and more to come up!

Integrating to a current Eloquent model

Integrating ipalaus/geonames with your existing Eloquent models as easy as:

<?php

class User extends Eloquent {

	public function geoname()
	{
		return $this->belongsTo('Ipalaus\Geonames\Eloquent\Name');
	}

}

Now you can a geoname_id to your User model and getting the results with a simple:

$user = User::with('geoname')->find(1);
echo $user->geoname->name;

The belongsTo country relationship in the Name model is always eager loaded. That means that you can get the country name with the same code as above. You just have to echo:

echo $user->geoname->country->name;

You can go a step further and eager loaded the geoname.country.continent relationship (or whatever existing relation in Geoname models):

$user = User::with('geoname.country.continent')->find(1);
echo $user->geoname->country->continent->name;

GeoNames

Tables reference

I think the original table names are ugly and they can conflict with other tables in a current project. I switched to a less uglier ones. You can check the migration files to see the used names for our database schema.
