I am working on a very simple Laravel application that basically presents a graph based on an id. I believe I have set up the correct route using:
app\Http\routes.php
<?php
/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/
Route::get('/', function () {
return view('welcome');
});
Route::get('getProcessorData', array('uses' => 'HonoursController@getProcessorData'));
#Route::get('getProcessorData/{id}', 'HonoursController@getProcessorData');
Route::get('getBandwidthData', array('uses' => 'HonoursController@getBandwidthData'));
Route::get('getMemoryData', array('uses' => 'HonoursController@getMemoryData'));
Route::resource('honours','HonoursController');
From there I went on to set up the correct function in the controller:
app\Http\Controllers\HonoursController.php
...
public function getProcessorData()
{
$id = Input::get('host_id');
return Response::json(HostProcessor::get_processor_formatted($id));
}
...
Since this called a function from the HostProcessor model, I created this function below:
app\HostProcessor.php
...
public static function get_processor_formatted($id)
{
$processor = self::findorfail($id);
$json = array();
$json['cols'] = array(
array('label' => 'Time', 'type' => 'string'),
array('label' => 'Kernel Space Usage', 'type' => 'number'),
array('label' => 'User Space Usage', 'type' => 'number'),
array('label' => 'IO Space Usage', 'type' => 'number')
);
foreach($processor as $p){
$json['rows'][] = array('c' => array(
array('v' => date("M-j H:i",strtotime($p->system_time))),
array('v' => $p->kernel_space_time),
array('v' => $p->user_space_time),
array('v' => $p->io_space_time)
));
}
return $json;
}
...
Finally I set up my AJAX function such as below:
resources/views/honours/partials/master.blade.php
...
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.charts.load('current', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var processor_usage = $.ajax({
url:'getProcessorData',
dataType:'json',
async: false
}).responseText;
var p_options = {
title: 'Processor Usage',
width: 800,
height: 400,
hAxis: {
title: 'Time',
gridlines: {
count: 5
}
}
};
...
Now the issue I am having here is when I try and pass a value to the HostProcessor function it fails. I have tried passing an id value using the data attribute of AJAX. By doing this I had to update my route to Route::get('getProcessorData?{id}', array('uses' => 'HonoursController@getProcessorData'));
but this still failed with a 404 error. I also tried just getting the value of host_id value using $id = Input::get('host_id');
and passing those to the HostProcessor function but that still failed with a 404 error. Any ideas why?
