Как переопределить форму чтоб пост стал под пользователем?

Question

[Alex_zver]

Нужно в

class PostCreateView(LoginRequiredMixin, CreateView):

добавить

def add_post(request):
    print (PostCreateForm)
    form = PostCreateForm(request.POST or None)
    # print (form)
    context = {'form': form}
    if request.method == 'POST' and form.is_valid():
        post = form.save(commit=False)
        formset = FileFormset(request.POST, files=request.FILES, instance=post)  # 今回はファイルなのでrequest.FILESが必要
        if formset.is_valid():
            post.save()
            formset.save()
            return redirect('app:index')

        # エラーメッセージつきのformsetをテンプレートへ渡すため、contextに格納
        else:
            context['formset'] = formset

    # GETのとき
    else:
        # 空のformsetをテンプレートへ渡す
        context['formset'] = FileFormset()

    return render(request, 'app/post_form.html', context)

Ума не приложу как сделать
forms.py

from django import forms
from .models import Post, File


class PostCreateForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        for field in self.fields.values():
            field.widget.attrs['class'] = 'form-control'

    class Meta:
        model = Post
        fields = '__all__'


FileFormset = forms.inlineformset_factory(
    Post, File, fields='__all__',
    extra=5, max_num=5, can_delete=False
)
