You can modify the fields in __init__ in the form. This is DRY since the label, queryset and everything else will be used from the model. This can also be useful for overriding other things (e.g. limiting querysets/choices, adding a help text, changing a label, …).

class ProfileEditPersonalForm(forms.ModelForm):    
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['country'].required = True

    class Meta:
        model = Profile
        fields = (...)

Here is a blog post that describes the same "technique": http://collingrady.wordpress.com/2008/07/24/useful-form-tricks-in-django/

In Django 3.0 if you for example want to make email required in user registration form, you can set required=True:

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm


class MyForm(UserCreationForm):
    email = forms.EmailField(required=True) # <- set here

    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']
