How to use geofield migrate extras

Question

I can not understand how to use migrate_extras and for example how to use geofield migrate extra support.

I have create a Migration class that work. In my "source" I have 2 "fields" called latitudine and longitudine. I have follow the instruction that I have found in geofiled.inc:

$geo_arguments = array(
  'lat' => array('source_field' => 'latitudine'),
  'lon' => array('source_field' => 'longitudine'),
);
// The geometry type should be passed in as the primary value.
$this->addFieldMapping('field_coordinate', 'Point')->arguments($geo_arguments);
// Since the excerpt is mapped via an argument, add a null mapping so it's
// not flagged as unmapped.
$this->addFieldMapping(NULL, 'latitudine');
$this->addFieldMapping(NULL, 'longitudine');

But my "test node" is created (via migrate) without "geofileld" field (field_coordinate). But if I comment the lines above and insert this function:

public function prepare($node, stdClass $current_row) {
  $node->field_coordinate = array(LANGUAGE_NONE => array(0 => array(
    'geom' => 'POINT ('.$current_row->longitudine." ".$current_row->latitudine.')',
    'geo_type' => 'point',
    'lat' => $current_row->latitudine,
             'lon' => $current_row->longitudine,
             'left' => $current_row->longitudine,
             'top' => $current_row->latitudine,
             'right' =>$current_row->longitudine,
            'bottom' => $current_row->latitudine,
   )));
}

"geofield field" is "created".

Where is my error?

Answer 1

Using arguments is deprecated.

Now you can migrate geofields without migrate_extras.

$this->addFieldMapping('field_location', 'point');

And in your prepare row

public function prepareRow($row) {
 $row->point = 'POINT (' . $row->longitude . ' ' . $row->latitude. ')';
}

Answer 2

Ok, I have found the solution.

From geofield.inc: "Primary value passed to this field must be the geometry type of the geofield: Point, LineString, Polygon" But this need to be passed in a different way:

• in the "prepareRow($row)" I need to set "Point" like a current row field:

  public function prepareRow($row) {
  [...] 
     $row->geo_type = 'point';
  [...]
  }
  

• and in the __construct() function the right line is:

  $this->addFieldMapping('field_coordinate', 'geo_type')->arguments($arguments);
  

Now it works.

Use of arguments is now deprecated. You will get this error:

The field mapping arguments() method is now deprecated - please use subfield notation instead.

To migrate geofield (2.0) using migrate_extras apply the patch in https://drupal.org/node/1997316.

Code using subfield notation:

$this->addFieldMapping('field_location', 'point');
$this->addFieldMapping('field_location:input_format', 'input_format');
$this->addFieldMapping('field_location:geo_type', 'point');
$this->addFieldMapping('field_location:lat', 'latitudine')
   ->xpath('Latitude');
$this->addFieldMapping('field_location:lon', 'longitudine')
   ->xpath('Longitude');

Inside prepareRow():

public function prepareRow($row) {
  ...
  $row->geo_type = 'point';
  $row->input_format = 'lat/lon';
  ...
}

Answer 4

Got it to work without migrate_extras:

in your prepareRow() use:

 $row->point = 'POINT (' . $row->longitude . ' ' . $row->latitude. ')';

and in the construct:

$this->addFieldMapping('field_location', 'point');
$this->addFieldMapping('field_location:geom', 'point');
$this->addFieldMapping('field_location:geo_type')->defaultValue('point');
