get results from one to one relationship - laravel-5

Question

I make one to one relationship between two table. One for employees and other for their timesheet.
When I want to see the employee hours is not working ! So far I just enter hours through phpmyadmin.
public function up()
{
Schema::create('timesheets', function (Blueprint $table) {
$table->increments('id');
$table->integer('starz_id');
//starz = employee. I just name it starz
for($i=1;$i<=31;$i++){
$table->integer('Jan'.$i)->nullable();
}
$table->timestamps();
});
}
<table class="table table-bordered table-hover">
<tr>
<td>Name</td>
#for($i=1;$i<=14;$i++)
<td>Jan{{$i}}</td>
#endfor
<td>Total</td>
</tr>
<tr>
#foreach($timesheet as $one)
<td>
{{$one->starz->name}}
</td>
#for($i=1;$i<=14;$i++)
<td>
{{ $one->Jan.$i }}
</td>
#endfor
</tr>
#endforeach
</table>
The resutl
Name Jan1 Jan2 Jan3 Jan4 Jan5 Jan6 Jan7 Jan8 Jan9 Jan10 Jan11 Jan12 Jan13 Jan14 Total
ali 1 2 3 4 5 6 7 8 9 10 11 12 13 14
Also I need to know please what is the right way to calculate the actual time. For ex: I want latter make function that caculate the actual hours working hours spent from start time (9am) and end time(6.30pm). How can I do this by laravel ?

Answer 1

i think what you want to achieve could have been done in other terms and it was gonna be easier for u. Allow me to write something for you
Employee.php
public class Employee{
public timesheets(){
return $this->hasMany(TimeSheet::class, 'starz_id');
}
}
TimeSheet.php
public class TimeSheet{
public employee(){
return $this->belongsTo(TimeSheet::class, 'starz_id');
}
}
timesheet migration
Schema::create('timesheets', function (Blueprint $table) {
$table->increments('id');
$table->integer('starz_id');
//now from your form i will encourage you log in an employee using their entry and exit time
$table->string('date')->nullable();
$table->string('entry_time')->nullable();
$table->string('exit_time')->nullable;
$table->timestamps();
});
with this you can use PHP to calculate the time worked maybe using Carbon library.
on rendering the employee time sheet you can improvise using some other logic. Looks like looping is you favorite
Your logic above will work but its not every month that has 31 days
