forms.py:

from django import forms

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=50)
    message = forms.CharField(widget=forms.Textarea)
    sender = forms.EmailField()
    cc_myself = forms.BooleanField(required=False)

views.py:

...
from .forms import ContactForm
from .models import Article
...

I'm getting a strange error:

Traceback (most recent call last):
  File "/home/danya/PycharmProjects/blog/article/views.py", line 8, in <module>
    from .forms import ContactForm
SystemError: Parent module '' not loaded, cannot perform relative import

What can be wrong?

Answer 1

try removing the dot
from forms import ContactForm
