How to save a multiple django forms into a database in a good way? Enhance Performance - mysql

Question

I want to save multiple django forms into a database in a good way, because it takes very long time to save these forms on a server.
the forms is related to each other, so I am using a serial saving technique "one form by one".
How can I maintain my forms to save quickly to database.
Forms Code:
employee_main=EmployeesForm(request.POST)
employee_administrative=EmployeesAdminstrativeForm(request.POST)
employee_stay=EmployeesStayForm(request.POST,request.FILES)
employee_dependents=EmployeesDependentsForm(request.POST,request.FILES,prefix="u")
employee_insurance=EmployeesInssuranceForm(request.POST,request.FILES)
employee_security=EmployeesSecurityForm(request.POST,request.FILES)
if employee_main.is_valid() and employee_administrative.is_valid() and employee_stay.is_valid() and employee_dependents.is_valid() and employee_insurance.is_valid() and employee_security.is_valid():
emp=employee_main.save(commit=False)
emp.save()
emp_ad=employee_administrative.save(commit=False)
emp_ad.employee_id=emp.id
emp_ad.save()
jobtitle_code=JobTitle.objects.get(id=emp_ad.jobtitle_id).Code
Employees.objects.filter(id=emp.id).update(Code=jobtitle_code +"-"+ str(emp_ad.employee_id+25))
Employees.objects.filter(id=emp_ad.moder_id).update(ismodeer=True)
emp_s=employee_stay.save(commit=False)
emp_s.employee_id=emp.id
emp_s.save()
emp_dd=employee_dependents.save(commit=False)
emp_dd.employee_id=emp.id
emp_dd.save()
emp_ss=employee_insurance.save(commit=False)
emp_ss.employee_id=emp.id
emp_ss.save()
from authentication.models import users
user=users(employee_id=emp.id,UserName=request.POST["UserName"],Password=request.POST["Password"],isadmin=0)
user.save()
return HttpResponseRedirect("/employees/all_employees/")

Answer 1

Put all the above code in a transaction.
Make Employee inherit User. Read more about model inheritance in Django.
You create the Employee object, then you update it using Employees.objects.filter(id=emp.id).update(Code=...). Just modify the code before the first save
django-modelcluster may help you. It's worth a try.
