# ✅ الصح — Template Tag في Django
{% for x in y %}
  {{ x }}
{% endfor %}

# ❌ غلط — أقواس Python عادية
(for x in y)

# ❌ غلط — صيغة PHP أو ERB
<% for x in y %>

from django.contrib import admin
from .models import Student

admin.site.register(Student)   # ← الـ Syntax الصح!

# ❌ غلط: admin.register(Student)
# ❌ غلط: site.admin.register(Student)
# ❌ غلط: models.admin.register(Student)

python manage.py createsuperuser

# الـ Terminal هيطلب منك:
# Username: admin
# Email: admin@example.com
# Password: ****

# بعدين افتح: http://127.0.0.1:8000/admin/

# ✅ الصح — من امتحان 2024
from members.models import Member

# ❌ غلط
import Member from members
import members.Member
