Django error. Unable to assign must be an instance

Question

I get the following error when I try to start pasting into one of my tables.

Cannot assign "1": "Team.department_id" must be an instance of "Department"

In truth, I'm not sure if I am using the foreign key concept correctly. The insert I am trying to run and the snippet from my .py models are given below.

What I'm trying to do is that when someone wants to create a new team. They must attach it to the department. Therefore, the department identifier must be in both sets of tables.

new_team = Team(
    nickname = team_name,
    employee_id = employee_id,
    department_id = int(Department.objects.get(password = password, department_name = department_name).department_id)
)

models.py

class Department(models.Model):  
    department_id = models.AutoField(auto_created=True, primary_key=True, default=1)  
    department_name = models.CharField(max_length=60)
    head_id = models.CharField(max_length=30)
    password = models.CharField(max_length=128)


class Team(models.Model):  
    team_id = models.AutoField(primary_key=True)
    department_id = models.ForeignKey('Department', related_name = 'Department_id')
    employee_id = models.CharField(max_length=30)
    nickname = models.CharField(max_length=60)
    team_image = models.ImageField(upload_to=get_image_path, blank=True, null=True)
