Why cannot I use a string variable of Django in Javascript?

Question

I'm currently learning Django/Python. I'm trying to use Django variables in html or javascript, which doesn't work as I desire. My models.py, and views.py files look like

class Student(models.Model):
    name = models.CharField(max_length=200)
    password = models.CharField(max_length=200)

Students' name is a string variable, like "Tanaka" or "Yoshida", and password is an integer variable, 1234 or something like this.

views.py

def index(request):
    all_students = Student.objects.all()
    context = {'all_students': all_students}
    template = loader.get_template('aaa/LogIn.html')
    return render(request,'aaa/LogIn.html', context)

the script code in LogIn.html file looks like

<script>
{% for student in all_students %}
        alert({{student.name}})
{% endfor %}
</script>

I want to use student.name in this code, but this doesn't work. If I change student.name to student.password, it works as expected. The question is why student.password appears in an alert message while student.name doesn't. I think the problem may be related to the variable type of name and password. How can I use Django variable in this case? Thank you, in advance.

alert("{{student.name}}") — you have to quote strings in JavaScript. — Pointy

I'd really suggest you don't store passwords in a charfield... if you're making a custom user model then you should follow the django docs.. — Sayse

This web site is not something Im creating for job or anything serious. So, passwords are not actually a password. Still, thank you for your advice. — Masa

Try:

alert("{{student.name}}");

Inject variables in string.
