Here is my models.py

Answer 1

from django.db import models

class Course(models.Model):
    name=models.CharField(max_length=10)
    courseid=models.CharField(max_length=30,primary_key=True)
class Enrollment(models.Model):
    course=models.ForeignKey(Course,on_delete=models.CASCADE)
    enrollid=models.CharField(max_length=20)

#Queryset:
k=Enrollment.objects.filter(course__courseid=1).values('id','course__courseid','course__name','enrollid')

print(k.query)
SELECT "app1_enrollment"."id", "app1_enrollment"."course_id", "app1_course"."name", "app1_enrollment"."enrollid" FROM "app1_enrollment" INNER JOIN "app1_course" ON ("app1_enrollment"."course_id" = "app1_course"."courseid") WHERE "app1_enrollment"."course_id" = 1
