Django how to iterate a form and save multiple objects? - django

Question

I have a modelform (model: Student) with a TextField where the user enters several names at once. My intention is for my view to parse this text input (getting a first name, last name, and then coming up with a nickname) and loop through the lines, saving a new student each time through the loop. However, only the last time through the loop is a student saved.
In the past I have solved this problem by using a custom save method in my model but I wanted to try doing it all in the view. I saw some posts in stackoverflow such as this one where it seemed that others were able to iterate through a loop and save objects.
models.py
class Student(models.Model):
classroom = models.ForeignKey(Classroom, on_delete=models.CASCADE)
student_first = models.CharField(default='John', max_length=30)
student_last = models.CharField(default='Smith', max_length=30)
nickname = models.CharField(default='JohnS', max_length=31)
attend = models.BooleanField(default=True)
do_not_pick = models.BooleanField(default=False)
multistudentinput = models.TextField(blank=True, default='')
def __str__(self):
return self.nickname
forms.py
class MultiStudentForm(ModelForm):
class Meta:
model = Student
fields = ('multistudentinput',)
views.py
def addmultistudent(request, classroom_id):
classblock = Classroom.objects.get(id=classroom_id)
if request.method == 'POST':
form = MultiStudentForm(request.POST)
if form.is_valid():
student = form.save(commit=False)
# save the classroom that the student belongs to
student.classroom = classblock
student_list = []
student_list = student.multistudentinput.split('\n')
for line in student_list:
line = line.strip('\r')
all_names = line.split()
num_names = len(all_names)
if num_names == 2:
last = all_names[1]
student.student_last = last
else:
last = ' '
student.student_last = ''
student.nickname = all_names[0] + last[:1]
student.student_first = all_names[0]
print(student)
student.save()
form = MultiStudentForm(None)
context = {'form': form}
return render(request, "gradebook/addmultistudent.html", context)
else:
context = {'form': form}
return render(request, "gradebook/addmultistudent.html", context)
else:
form = MultiStudentForm(None)
context = {'form': form}
return render(request, "gradebook/addmultistudent.html", context)
