Question

I have created a model with some classes:

class Student(models.Model):
    name = models.CharField(max_length=40)
    last_name = models.CharFIeld(max_length=40)
(...)

and in the same models.py file at the bottom I’ve added a class corresponding to one of my models so i can create a form:

class StudentForm(ModelForm):
    class Meta:
        model = Student

How do I customize form fields created via ModelForm class ? I was reading django Documentation and I can’t understand overriding the default types part.
For example, in documentation they say this will work:

class ArticleForm(ModelForm):
    pub_date = DateField(label='Publication date')

    class Meta:
        model = Article

but when i type my values it’s not working. I can’t define my label:

class StudentForm(ModelForm):
    name = CharField(label='New label')

    class Meta:
        model = Student

Do i have to create a file like forms.py with identical fields as in Model class and then customize them ? Is it possible to change single field css attributes like width, height using only Model Forms ?

Field for form use a difference library to create a from. You need to import django.forms and use form.XXX for specific Field

from django import forms


class StudentForm(ModelForm):
    class Meta:
        model = Student

    subject = forms.CharField(label='New label')
