RemovedInDjango18Warning: Creating a ModelForm without either the ‘fields’ attribute or the ‘exclude’ attribute is deprecated

For your form, it’s a warning, not an error, telling you that in django 1.8, you will need to change your form to

from django import forms
from models import Article

class ArticleForm(forms.ModelForm):

    class Meta:
        model = Article 
        fields="__all__" # Or a list of the fields that you want to include in your form

Or add an exclude to list fields to exclude instead

Which wasn’t required up till 1.8

https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/#selecting-the-fields-to-use

As for the error with your views, your return is inside of an if statement: if request.POST: so when it receives a get request, nothing is returned.

def create(request):
    if request.POST:
        form = ArticleForm(request.POST)
        if form.is_valid():
            form.save()

            return HttpResponseRedirect('/articles/all')

    else:
        form = ArticleForm()

    args = {}
    args.update(csrf(request))

    args['form'] = form 

    return render_to_response('create_article.html', args)

Just dedent the else block so that it’s applying to the correct if statement.
