Calculate percentage in Symfony2 - php

Question

I have two entities, Projects and Tasks with their respective repositories.
I am trying to create a function that will calculate the totalNumberOfTasks() , totalNumberOfCompletedTasks() and getPercentComplete().
totalNumberOfTasks() basically will fetch all the data related with a specific project_id from the tasks table.
totalNumberOfCompletedTasks() will query all the data relevant with specific project_id but only those marked as COMPLETED from the tasks table.
getPercentComplete() will calculate the percent based on the totalNumberOfTasks() and totalNumberOfCompletedTasks() functions and print in the view file.
I have tried doing {{ project.tasks|length }} % in Twig file which fetched only the total number of tasks relating to that specific id. How do I get total number of tasks and completed tasks, find the percentage then show it in the view file where every projects are shown?
Sorry for my english. I am just not being able to make the question more understandable.

return $this->render('TestBundle:Default:index.html.twig', 'projects' => $entities]);
}
}

Answer 1

you can archive this problem using the Doctrine Criteria instead of make a custom Repository method. As Example you can add the following method to your Projects Entity class:
use Doctrine\Common\Collections\Criteria; // IMPORT THIS!
use Doctrine\ORM\Mapping as ORM;
/**
* Projects
* #ORM\Table()
* #ORM\Entity(repositoryClass="TaskManagerBundle\Entity\Repository\ProjectsRepository")
* #ORM\HasLifecycleCallbacks()
*/
class Projects
{
...
public function getCompleteTasks()
{
$expr = Criteria::expr();
$criteria = Criteria::create();
$criteria->where($expr->eq('completed', true));
return $this->getTasks()->matching($criteria);
}
public function getNumberOfTasks()
{
return $this->getTasks()->count();
}
public function getPercentComplete()
{
$percentage = 0;
$totalSize = $this->getNumberOfTasks();
if ($totalSize>0)
{
$completedSize = $this->getCompleteTasks()->count();
$percentage = $completedSize / $totalSize * 100;
}
return $percentage;
}
...
}
Then you can use in your Twig template as follow:
{{ project.percentComplete|number_format(2, '.', ',') }}
Hope this help.
