Cakephp : ShellのCron実行

パラメタを自動取得するため、Shellを作成しCronで実行しました。

１．Shellの作成
app]$ vi Console/Command/MapShell.php

	<?php
	class MapShell extends Shell {
	function main () {
	App::import('Model','Firedistrict');
	$this->Firedistrict = new Firedistrict;
	$fires = $this->Firedistrict->find('all',
	array(
	'conditions' => array('distance' => null),
	'limit' => 3,
	)
	);
	foreach($fires as $fire){
	$distance = $this->getDirection($fire['Firedistrict']['firelatitude'],$fire['Firedistrict']['firelongitude'],$fire['Firedistrict']['distlatitude'],$fire['Firedistrict']['distlongitude']);
	$data = array(
	'id' => $fire['Firedistrict']['id'],
	'distance' => $distance[0],
	'duration' => $distance[1]
	);
	$this->Firedistrict->save($data);
	}
	}
	public function getDirection($orglat, $orglon, $dstlat, $dstlon){
	$datas = file_get_contents("http://maps.googleapis.com/maps/api/directions/json?origin=$orglat,$orglon&destination=$dstlat,$dstlon&sensor=false");
	$directions = json_decode($datas);
	//print_r ($directions);
	$direction = $directions->routes[0]->legs[0];
	$distance = $direction->distance->value;
	$duration = $direction->duration->value;
	$result = array($distance, $duration);
	return $result;
	}
	}
	?>

２．スクリプトファイルの作成
app]$ vi Vendor/CakeShell.sh

	#!/bin/bash
	cd ~
	cd www/app
	Console/cake map

実行権限を与えます。
app]$ chmod +x Vendor/CakeShell.sh

３．cron設定
$ crontab -e
*/2 * * * * /home/mznqueue/www/app/Vendor/CakeShell.sh
２分に１回実行

凸集合の描画

いくつか点があるときに凸集合を作成して描画をしました。

１．ライブラリの用意
今回は下記のライブラリを使いました。
https://github.com/benpoulson/PHP-ConvexHull/blob/master/convexHull.php
関数になっていたのでAppController.phpに追加しておきました。

２．コントローラでの呼び出し
コントローラから下記のように呼び出します。

	public function convex() {
	$this->Tsp->recursive = 0;
	$this->paginate = array(
	'limit'=>10000,
	'maxLimit' => 30000,
	);
	$this->set('tsps', $this->Paginator->paginate());
	$tsps = $this->Paginator->paginate();
	$input = array(array());
	for($i = 0; $i < count($tsps); $i++){
	$input[$i][0] = $tsps[$i]['Tsp']['latitude'];
	$input[$i][1] = $tsps[$i]['Tsp']['longitude'];
	}
	$output = $this->convexHull($input);
	$this->set('output', $output);
	}

３．ビューでの描画
ビューで描画します。

	<script type="text/javascript" src="http://maps.google.com/maps/api/js?key=MyKey&sensor=false"></script>
	<div class="tsps index">
	<h2><?php echo __('Tsps'); ?></h2>
	<?php
	$map_options = array(
	'id' => 'map1',
	'width' => '1200px',
	'height' => '800px',
	'zoom' => 13,
	'type' => 'ROAD',
	//'custom' => null,
	'localize' => false,
	'latitude' => $tsps[0]['Tsp']['latitude'],
	'longitude' => $tsps[0]['Tsp']['longitude'],
	'marker' => true,
	'markerIcon' => 'https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png',
	'markerShadow' => 'http://google-maps-icons.googlecode.com/files/shadow.png',
	'infoWindow' => true,
	'windowText' => "自分で指定"
	);
	?>
	<div id="map">
	<?php echo $this->GoogleMap->map($map_options); ?>
	</div>
	<?php $marker_index =1; ?>
	<?php foreach ($tsps as $tsp): ?>
	<?php
	$marker_options = array(
	'showWindow' => true,
	'windowText' =>$tsp['Tsp']['id'].":".$tsp['Tsp']['name'],
	'markerTitle' => 'Title',
	'markerIcon' => 'http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld='.$tsp['Tsp']['id'].'|ff7e73|000000',
	'markerShadow' => 'http://labs.google.com/ridefinder/images/mm_20_purpleshadow.png'
	);
	echo $this->GoogleMap->addMarker('map1', $marker_index, array('latitude' => $tsp['Tsp']['latitude'], 'longitude' =>$tsp['Tsp']['longitude'] ),$marker_options);
	$marker_index ++;
	?>
	<?php endforeach; ?>
	<?php for($i = 0; $i < count($output); $i++){ ?>
	<?php
	if($i == count($output)-1){
	echo $this->GoogleMap->addPolyline("map1", "polyline", array(
	"start" => array("latitude" => $output[$i][0] ,"longitude"=> $output[$i][1]),
	"end" => array("latitude" => $output[0][0] ,"longitude"=> $output[0][1])
	));
	}
	else{
	echo $this->GoogleMap->addPolyline("map1", "polyline", array(
	"start" => array("latitude" => $output[$i][0] ,"longitude"=> $output[$i][1]),
	"end" => array("latitude" => $output[$i+1][0] ,"longitude"=> $output[$i+1][1])
	));
	}
	?>
	<?php } ?>
