New Field In Django-admin Add User

I'm using Django 1.7.1 and here I encountered issue that shouldn`t really took place. Background: I'm working on customized user model based on AbstractUser. For now - I've got the

Solution 1:

I'm not sure if the problem was with specific lines order in NewUserAdmin class or something else - haven`t tested it yet, but I'm pretty sure I was close to this solution much earlier. However this is the exact thing I was talking about (it is working the way I wanted it to :) ). I can now easy add any field to user model and it is still connected to all framework functions like sessions management, and so on. What is more - I don't use AbstractBaseUser nor OneToOne field, which caused a lot of problems. Anyway - thanks for any way of help. I wouldn't resolve it without you... ...this week :D

PS I skipped all imports. IDE will tell you, what is needed.

models.py

classNewUserManager(UserManager):
defcreate_user(self, username, email=None, password=None, **extra_fields):
    return UserManager.create_user(self, username, email=email, password=password, **extra_fields)

defcreate_superuser(self, username, email, password, **extra_fields):
    return UserManager.create_superuser(self, username, email, password, **extra_fields)

classNewUser(AbstractUser):
    newField = models.CharField()       # for example CharField
    newField = models.CharField(max_length = 12) # important thing - properties should be in the second line
    objects = NewUserManager()

    classMeta(AbstractUser.Meta):
        swappable = 'your_app_name.NewUser'#db_table = 'auth_user'    

forms.py

classNewUserCreationForm(forms.ModelForm):
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

    classMeta:
        model = NewUser
        fields = ('username', 'email', 'first_name', 'last_name', 'newField')       # few example fields and new one: newFielddefclean_password2(self):
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords don't match")
        return password2

    defsave(self, commit=True):
        user = super(NewUserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user

classNewUserChangeForm(UserChangeForm):
    classMeta(UserChangeForm.Meta):
        model = NewUser
        fields = ('username', 'email', 'first_name', 'last_name', 'newField', 'last_login', 'is_staff')     # few example fields and new one: newField    

admin.py

classNewUserAdmin(UserAdmin):
    form = NewUserChangeForm
    add_form = NewUserCreationForm

    list_display = ('username', 'newField', 'first_name', 'last_name', 'last_login',)       # few example fields and new one: newField
    fieldsets = (
        (None, {'fields': ('username', 'email', 'first_name', 'last_name', 'newField', 'last_login', 'is_staff')}), # few example fields and new one: newField

    add_fieldsets = (
        (None, {
        'classes': ('wide',),
        'fields': ('username', 'newField', 'password1', 'password2')}   # here are fields you want to have in django-admin AddUser view
    ),           # one of the most important place above
)

admin.site.register(NewUser, NewUserAdmin)
