How to assign initial value to a custom fields in ModelAdmin?

django, django-admin, django-forms

Solution

try this:

class ProfileAdmin(admin.ModelAdmin):
    form = ProfileForm
    # ...
    def get_form(self, request, obj=None, *args, **kwargs):
        form = super(ProfileAdmin, self).get_form(request, *args, **kwargs)
        #find the user via user profile forien key
        the_user = User.objects.filter(pk=Profile.user.pk)
        # Initial values
        form.base_fields['username '].initial = the_user.username
        return form

also try this and see the diff: (fields lives only after super call)

        form.fields['username '].initial = the_user.username

Problem

I am trying to extends django user auth through onetonefield in model. Here is the model: ``` from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) nim = models.CharField(max_length=10, blank=True) def __str__(self): return self.user.username ``` With basic admin panel i get to create user instance first and then profile. But i use custom forms on admin panel so i can create it on one form.This is the forms look: Profile add form this is forms.py ``` from django import forms from django.contrib.auth.models import User from .models import Profile class ProfileForm(forms.ModelForm): username = forms.CharField(required=False, max_length=150) password = forms.CharField(required=False, max_length=50, widget=forms.PasswordInput) class Meta: model = Profile fields = ('username', 'password', 'nim') ``` and this is admin.py ``` from django.contrib import admin from django.contrib.auth.models import User from .forms import ProfileForm from .models import Profile class ProfileAdmin(admin.ModelAdmin): form = ProfileForm def save_model(self, request, obj, form, change): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = User.objects.create_user(username=username, password=password) user.save() obj.user = user obj.save() admin.site.register(Profile, ProfileAdmin) ``` With this all i can create profile instance just fine. But when i try to change/edit profile it didn't show initial value for username and password fields, only nim field did. empty username and password field Thanks for your help
