Implementing GeocodableBehavior in Symfony 1.4 (using Propel)

Question

I'm trying to implement the GeocodableBehavior on a Symfony 1.4 (with Propel 1.6) project i'm working on, but until now it's a complete failure. I've tried to search if other people but I didn't found anything, like if I was the only one having troubles with this.

So, maybe I'm missing something very very easy, but following the instructions given on the GeocodableBehavior leads to nothing but errors, and I can't figure out where's the problem.

I followed instructions for the GeocodableBehavior (here -> http://www.propelorm.org/cookbook/geocodable-behavior.html)

This seems to work as i'm getting the latitude/longitude columns created on my model. Until then, it works fine.

Where things get a little more complicated is when trying to save an object with the GeocodableBehavior, there's problems with the Geocoder class.

(Documentation here -> https://github.com/willdurand/Geocoder)

My class is Point, referring to a geolocated point, an address. When creating a Point using sf admin generator, the behavior which is supposed to use some fields (street, postal_code, country, etc) to query the GoogleMaps api, just fails to use the Geocoder class.

Fatal error: Class 'Geocoder\Geocoder' not found in /var/www/vhosts/www._________.local/lib/model/om/BasePoint.php on line 3717

I put the Geocoder class in a lib/vendor/geocoder folder, I tried to use the autoload.yml file to load it, but nothing changes...

autoload:
  geocoder:
    name:       geocoder
    path:       %SF_LIB_DIR%/vendor/geocoder
    recursive:  on

There's something i'm missing in how to load those classes in my sf project, and i can't find what. Geocoder package has an autoload.php file but i didn't manage to "load" it successfully...

Thanks in advance.

I know it's kinda giving up on the autoloader, but you could establish a register function in /config/ProjectConfiguration.class.php. The only downside is that you will need to add a call to the function before any block that uses Geocoder.

class ProjectConfiguration extends sfProjectConfiguration
{
    static protected $geocoderLoaded = false;

    static public function registerGeocoder()
    {
        if (self::$geocoderLoaded) {
            return;
        }

        require_once sfConfig::get('sf_lib_dir') . '/vendor/geocoder/autoload.php';

        self::$geocoderLoaded = true;
    }
    ...
}

Then just execute ProjectConfiguration::registerGeocoder(); anywhere you'd need the class. It's more annoying than getting the autoloader to work, but it's at least dependable.

Did you check your autoload cache to see it there is something related to Geocoder?

• /cache/[apps_name]/dev/config/config_autoload.yml.php
• /cache/project_autoload.cache

Maybe, manually add the autoload in the /config/ProjectConfiguration.class.php:

class ProjectConfiguration extends sfProjectConfiguration
{
  public function setup()
  {
    require_once sfConfig::get('sf_lib_dir').'/vendor/geocoder/src/autoload.php';

Using the built-in autoloader should be a working option, but you can also combine symfony's autoloader with a "PSR-0 enabled" one. Basically, this boils down to the following implementation:

public function setup()
{
  // plugin stuff here

  // register the new autoloader
  spl_autoload_register(array($this, 'autoloadNamespace'));
}

public function autoloadNamespace($className)
{
  $className = ltrim($className, '\\');
  $fileName = ''; 
  $namespace = ''; 
  if ($lastNsPos = strripos($className, '\\'))
  {   
    $namespace = substr($className, 0, $lastNsPos);
    $className = substr($className, $lastNsPos + 1); 
    $fileName = str_replace('\\', DIRECTORY_SEPARATOR, $namespace) . DIRECTORY_SEPARATOR;
  }   

  // make sure that the path to Geocoder is correct
  foreach(array(
    sfConfig::get('sf_lib_dir').'/vendor/Geocoder/src' . DIRECTORY_SEPARATOR . $fileName . $className . '.php', 
    ) as $fileName)
  {   
    if (file_exists($fileName))
    {   
      require $fileName;
      return true;
    }   
  }   
  return false;
}

With this additional autoloader, your application should be able to use Geocoder.
