Laravel Quiz Storing The correct answers - php

Question

I am very new to the Laravel, so I have a project for making a quiz. Currently I achieved to store my questions with radio-answers in the database, but I do not know how to:
1) Display all the questions with answers on web page.
2) Store the points for the user on each correct answer.
UPDATE: Thanks to ettdro I have solved my 1st problem. Only my 2nd left.
I would appreciate any help.
My Answer.php Model is empty for now. My Question.php Model:
class Question extends Model
{
// connect the models by adding a relationship to the Question model
public function answers()
{
return $this->hasMany(Answer::class);
}
}
My up function in Migration for Questions is:
public function up()
{
Schema::create('questions', function (Blueprint $table) {
$table->id();
$table->string('text');
$table->integer('points')->unsigned();
$table->timestamps();
});
}
My up function in Migration for Answers is:
public function up()
{
Schema::create('answers', function (Blueprint $table) {
$table->id();
// since answer is connected to the question
$table->integer('question_id');
$table->string('text');
$table->boolean('correct_one');
$table->timestamps();
});
}
My QuestionAnswerSeeder.php is:
// for filling the tables
class QuestionAnswerSeeder extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
// truncating the tables and then store each question and its answers.
public function run()
{
Question::truncate();
Answer::truncate();
$questionAndAnswers = $this->getData();
$questionAndAnswers->each(function ($question) {
$createdQuestion = Question::create([
'text' => $question['question'],
'points' => $question['points'],
]);
collect($question['answers'])->each(function ($answer) use ($createdQuestion) {
Answer::create([
'question_id' => $createdQuestion->id,
'text' => $answer['text'],
'correct_one' => $answer['correct_one'],
]);
});
});
}
// for the actual data, I use a separate getData method to keep it cleaner
// in this method, I return a big collection with all the questions and answers
private function getData()
{
return collect([
[
'question' => 'When did the World War 2 end?',
'points' => '1',
'answers' => [
['text' => '1939', 'correct_one' => false],
['text' => '1941', 'correct_one' => false],
['text' => '1945', 'correct_one' => true],
],
],
[
'question' => 'Who discovered America?',
'points' => '1',
'answers' => [
['text' => 'Adolf Hitler', 'correct_one' => false],
['text' => 'Napoleon Bonaparte', 'correct_one' => false],
['text' => 'Christopher Columbus', 'correct_one' => true],
],
],
]);
}
}

You should have a QuestionController.php that has this content:
/**
* In this function, you need to get all the data you want to pass to your view
* and send it to the compact function in the return statement.
*/
public function index() {
// This will return a collection of questions including their answers.
$questionsCollection = Question::all();
return view('myquestionsview', compact('questionsCollection'));
}
Next, because you returned myquestionsview in the index function, you will need a file named: myquestionsview.blade.php in the views folder.
To display the informations of your questions, in your myquestionsview.blade.php you should have something like
#foreach ($questions as $question)
{{ $question->text }}
// Now, we want to display each answers of the question.
#foreach ($question->answers as $answer)
{{ $answer->text }}
#endforeach
#endforeach
This is basically what you want to do for your first question.
