Question

My django project file structure

  myProject
       |--newsletter
           |--__init__.py
           |--admin.py
           |--forms.py
           |--models.py
           |--tests.py
           |--urls.py
           |--views.py
       |--myproject
           |--settings.py
           |--urls.py
           |--wsgi.py

       |--db.sqlite3
       |--manage.py

code in models.py

from django.db import models
class SignUp(models.Model):

    email = models.EmailField()
    first_name = models.CharField(max_length=120)
    last_name = models.CharField(max_length=120, blank=True)
    subscribtion_type_choices = (
        ('W', 'Weekly'),
        ('M', 'Monthly'),
        ('Y', 'Yearly')
    )
    subscribtion_type = models.CharField(max_length=1, choices=subscribtion_type_choices)

    def __str__(self):
        return self.first_name

code in admin.py

from django.contrib import admin
from newsletter.forms import SignUpForm
from newsletter.models import SignUp

class SignUpAdmin(admin.ModelAdmin):
    # list_display = ('first_name', 'last_name', 'email', 'subscribtion_type')
    form_signup = SignUpForm

admin.site.register(SignUp, SignUpAdmin)

code in forms.py

from django import forms
from newsletter.models import SignUp

class SignUpForm(forms.ModelForm):

    class Meta:
        model = SignUp
        fields = ['first_name', 'last_name', 'email', 'subscribtion_type', ]

Answer 1

Just guess. Try add . before newsletter imports in admin.py and forms.py , eg

from .newsletter.forms import SignUpForm

Answer 2

You have to add __init__.py file inside myproject folder. Also try import like this

from .models import SignUp
