将 AWS S3 存储桶与 Django 一起使用时出现 TypeError

Question

I'm brand new to Django and AWS S3 and seem to have hit a wall. This is all on localhost at the moment. I'm trying to add a new product through my own admin app for a Art Gallery website i'm working on, all worked fine originally when adding a product, but since using AWS S3 i receive the following TypeError:

The error states that it's expecting "...a string or bytes-like object." and refers to the following lines of code in both my mixins.py and my staff views.py

mixins.py:

from django.shortcuts import redirect


class StaffUserMixin(object):
    def dispatch(self, request, *args, **kwargs):
        if not request.user.is_staff:
            return redirect("home")
        return super(StaffUserMixin, self).dispatch(request, *args, **kwargs)

views.py:

class ProductCreateView(LoginRequiredMixin, StaffUserMixin, generic.CreateView):
    template_name = 'staff/product_create.html'
    form_class = ProductForm

    def get_success_url(self):
        return reverse("staff:product-list")

    def form_valid(self, form):
        form.save()
        return super(ProductCreateView, self).form_valid(form)

As I stated at the start i'm very new to both Django and AWS S3, so if this is just a schoolboy error, please forgive me but any help would be fantastic. And if any additional info is needed i'll be happy to provide. Thanks!

You need to write some lines in your settings.py file in order to get django-storages to work.

Those lines are:

AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID')
AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY')
AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME')

and you need to identify those variables in your .bash_profile file (if you are on mac) so that they are not committed to your version control system for security reasons.

You need to follow this syntax:

export AWS_ACCESS_KEY_ID="YOUR_ID" **(NO SPACES)**
export AWS_SECRET_ACCESS_KEY="YOUR_SECRET_KEY"
export AWS_STORAGE_BUCKET_NAME="YOUR_BUCKET_NAME"

and then you need to provide Heroku (on which I encountered this error) with this data by using configVars .

In your Terminal/CommandLine:

heroku config:set AWS_ACCESS_KEY_ID="YOUR_ID"
heroku config:set AWS_SECRET_ACCESS_KEY="YOUR_SECRET_KEY"
heroku config:set AWS_STORAGE_BUCKET_NAME="YOUR_BUCKET_NAME"

Make sure to use double-quotes!
