I'm having trouble outputting a list of key value pairs in Laravel blade.
My show.blade.php template is:
@extends('layouts.app')
@section('content')
<ul>
@foreach ($datapoint as $key => $value)
<li>{{ $key, $value }}</li>
@endforeach
</ul>
{{ $datapoint }}
@endsection
And my controller which displays this template is:
<?php
namespace App\Http\Controllers;
use App\Hyfes;
use Illuminate\Http\Request;
class CaptainController extends Controller
{
public function getLiveData ()
{
$datapoint = Hyfes::find(1);
return view('captain.show')->with('datapoint', $datapoint);
}
}
The data output to the view in the browser is this:
timestamps
{"date":"08/07/2017","time":"12:02:25","boat_name":"cyclone","current_location":"North Greenwich Pier","status":"docked","embarked":26,"disembarked":2,"people_on_board":24,"current_speed":0,"hotel_power":231,"battery_power_demand":342,"battery_output_power":23,"engine_output_power":12,"battery_power_stored":100,"battery_depth_of_discharge":323,"fuel_consumption_rate":7,"nox":432,"co2":213,"battery_state_of_charge":100,"id":1}
Ideally, I would like to see a list of bullet points showing e.g.:
The function Hyfes::find(1) will return an object of the type App\Hyfes and not an array. By looping over the key value pairs you are getting all properties. Laravel adds a lot of extra properties for keeping track of the object.
A better way to do this is using the Laravel getAttributes function. This will only get the attributes loaded from the database. Like so:
@foreach ($datapoint->getAttributes() as $key => $value)
<li>{{ $key }}: {{ $value }}</li>
@endforeach
You are trying to iterate over a non array variable in your template. You have to be explicit about the values of the objects you would like to see in your template.
@extends('layouts.app')
@section('content')
<ul>
<li>date: {{ $datapoint->date }}</li>
<li>time: {{ $datapoint->time }}</li>
<!-- and so on -->
</ul>
@endsection
