I am trying to change my label in Forms. But despite trying, I can't get a label change for consumer field. I also don't see a typo made by me.
models.py
class Offer(models.Model):
owner = models.ForeignKey(CustomUser, on_delete=models.CASCADE)

I use my form as method {{ form.as_p }}. I guess I might be making some stupid mistakes. But I don't see the wrong setting and my label is still costumer instead of klient. How to change costumer label to klient.

I am creating a student attendance form where need to get details of student name, student class and Id from student model based on teacher selecting student class in one form. I have tried using initial by using for loop on query data to prefill the form in formset, however it populates data for one record only. Below is the code for forms.py, models and views.py. Can someone help on this
forms.py
class student(models.Model):
studentid = models.AutoField(primary_key=True)
Gender = models.CharField(max_length=6, choices=gender, null=True)
Name = models.CharField(max_length=100, null=True)

AttendanceFormSet = formset_factory(std_attendance, extra=(len(formset_data))-1)
for element in formset_data:
formset = AttendanceFormSet(initial=[
{'Student_ID': element.studentid, 'Student_Name':element.Name, 'Student_class':element.Current_class, 'Attendance_status':"Present"}
])
param = {'formset':formset}
return render(request, 'home/student_attendance.html', param)
return render(request, 'home/student_attendance.html')
form.py:
class student_register(ModelForm):

model = student
fields = '__all__'
class std_attendance(ModelForm):
class Meta:

Each iteration in your loop you override the formset, that is why only a single form is filled, you need to fill the param with all the forms inside the loop this way:
initial = []
for element in formset_data:
initial.append({'Student_ID': element.studentid, 'Student_Name':element.Name, 'Student_class':element.Current_class, 'Attendance_status':"Present"}
formset = AttendanceFormSet(initial=initial)
I have followed this tutorial to implement inlneformset.

I am using a form that saves to one model to update the most current mileage which is stored in another model. I want to make sure the mileage entered is > or = the current mileage. I havent been able to figure out the right validation or where to write the validation.
I have tried an if statement in the form_valid() of the CreateView and a save() method in the model.
