Here is my updated code for EmployeeModel:
Employee Model (Updated)
class Employee(models.Model):
ACTIVE = 1
INACTIVE = 2
DELETED = 3
STATUS_CHOICES = (
(ACTIVE, 'active'),
(INACTIVE, 'inactive'),
(DELETED, 'deleted'),
)
USER_TYPE = (
(1, 'user'),
(2, 'hr'),
)
employee_id = models.CharField(max_length=15, primary_key=True)
Name = models.CharField(max_length=100, null=False)
designation = models.CharField(max_length=30, null=False)
department_id = models.IntegerField(null=False)
manager_id = models.CharField(max_length=15, null=False)
date_of_joining = models.DateField(null=False)
date_of_birth = models.DateField(null=False)
location_id = models.IntegerField(null=False)
email = models.EmailField(max_length=100, unique=True,
null=False)
contact_number = models.CharField(max_length=10 , unique=True,
null=False)
password = models.CharField(max_length=100, null=False)
created_on = models.DateTimeField(auto_now_add=True)
created_by = models.CharField(max_length=100, null=False)
modified_on = models.DateTimeField(auto_now_add=True)
modified_by = models.CharField(max_length=100, null=True)
status = models.CharField(max_length=10, null=False,
choices=STATUS_CHOICES)
user_type = models.CharField(max_length=10, choices=USER_TYPE)
objects = UserManager()
USERNAME_FIELD = "email"
REQUIRED_FIELDS = ["Name"]
is_anonymous = "FALSE"
is_authenticated = "TRUE"
class Meta:
managed = True
db_table = "ht_employee"

You should update the department_id field in the employee as a foreign key in order to get the name of the department so it will be as:
class Employee(models.Model):
department = models.ForeignKey(Department)
and then to get the department name in template
{{employee.department.department_name}}
