how to filter foreign key in django form without passing foreign key value?

I have created two models in my django project AddStudent and Fee Entry as shown below.

models.py

class AddStudent(models.Model):      enrollment_no = models.BigIntegerField(primary_key=True)      student_name = models.CharField(max_length=500,null=True)      gender = models.CharField(max_length=1,choices=GENDER_CHOICES)      course = models.ForeignKey(CourseMaster, on_delete=models.DO_NOTHING, null=True)      category= models.ForeignKey(CatMaster, on_delete=models.DO_NOTHING, null=True)      admission_year = models.IntegerField(('year'), choices=YEAR_CHOICES, default=datetime.datetime.now().year)      college = models.ForeignKey(CollegeMaster, on_delete=models.DO_NOTHING, null=True)      branch = models.ForeignKey(BranchMaster,on_delete=models.DO_NOTHING, null=True)      current_semester = models.IntegerField(null=True)      address = models.CharField(max_length=1000,null=True)      city = models.CharField(max_length=100,null=True)      district = models.CharField(max_length=100,null=True)      state = models.CharField(max_length=100,null=True)      student_contact = models.BigIntegerField()      parent_contact = models.BigIntegerField()        def get_absolute_url(self):          return reverse('add_student:index')        def __str__(self):          return str(self.enrollment_no) + ' - ' + self.student_name    class FeeEntry(models.Model):        student = models.ForeignKey(AddStudent,on_delete=models.DO_NOTHING)      fee_detail = models.ForeignKey(FeeMaster,on_delete=models.DO_NOTHING)      fee_sem = models.IntegerField(null=True)      payment_date = models.DateField(("Date"), default=datetime.date.today)      pay_method = models.BooleanField(choices=BOOL_CHOICES)      cheque_no = models.CharField(max_length = 100, null=True, blank=True)      bank_name = models.CharField(max_length = 200, null=True, blank=True)        def __str__(self):          return str(self.id) + ' - ' + str(self.student) + ' - ' + self.student.student_name

Now when user search particular student for example student id = 1 than student profile page will open and there is another button addfee. My problem is when user click on add fee all 500 student list is appear in dropdown list. i want to create fee for searched student only.

forms.py

from django import forms  from .models import FeeEntry, AddStudent  from bootstrap_modal_forms.mixins import PopRequestMixin, CreateUpdateAjaxMixin    class FeeForm(PopRequestMixin, CreateUpdateAjaxMixin, forms.ModelForm):      class Meta:          model = FeeEntry          fields = ['student', 'fee_detail', 'fee_sem', 'payment_date', 'pay_method','cheque_no','bank_name']

above is my forms.py file where field 'student' will generate all 500 student list. I want only selected student for example enrollment_no=1 when user is on enrollment_no 1's page.

views.py

class FeeCreateView(PassRequestMixin, SuccessMessageMixin,                           generic.CreateView):      template_name = 'add_student/create_fee.html'      form_class = FeeForm      success_message = 'Success: Book was created.'      success_url = reverse_lazy('add_student:detail')  

urls.py

path('create/<int:pk>', views.FeeCreateView.as_view(), name='create_fee'),  

Can anyone tell me what changes are required in this code? or can you share link of similar example like this?
