Foreign Key related form Saving in Django - django

Question

My Models are look like .....
Student(models.Model):
name = models.CharField(max_length = 60, blank = False)
r_no = models.CharField(max_length = 60, blank = False)
created_date = models.DateTimeField(null = False, blank = False, default = datetime.datetime.now())
StudentPotential(models.Model):
aka_name = models.CharField(max_length = 60, blank = True)
-----

StudentCorrespondence(models.Model):
student = models.ForeignKey('Student', related_name = "Student_FK")
student_p = models.ForeignKey('Student', related_name = "Student_FK")
emailed_date = models.DateTimeField(null = True, blank = True)
phoned_date = models.DateTimeField(null = True, blank = True)
My Form in form.py
class StudentPotentialForm (forms.ModelForm):
class Meta:
model = StudentPotential
class StudentCorrespondenceForm(forms.ModelForm):
class Meta:
model = StudentCorrespondence
exclude = ('student', 'student_p')
Finally My view.py
def add_student_company_potential(request, student_id):
from cdradmin.forms import StudentPotentialForm, StudentCorrespondenceForm
if request.method == 'POST':
### HOW TO SAVE THE two from for the student have its it 'student_id' ####
else:
StudentPotentialForm = StudentPotentialForm()
StudentCorrespondenceForm = StudentCorrespondenceForm()
context = {'StudentCorrespondenceForm':StudentCorrespondenceForm, "StudentPotentialForm":StudentPotentialForm}
return render_to_response('cdradmin/studentform.html', context, context_instance = RequestContext(request))
Once the data is post to the view, How can i able to save this data for the student has his/her id is 'student_id'

Answer 1

You can try this
if request.method == 'POST':
spf = StudentPotentialForm(request.POST)
if spf.is_valid():
osp = spf.save()
else :
#raise error
student = Student.objects.get(id=student_id)
scf = StudentCorrespondenceForm(request.POST)
if scf.is_valid():
osc = scf.save(commit=False)
osc.student = student
osc.student_p = osp
osc.save()
else:
# raise error.
