How do I attach image files in Django-summernote? - django

Question

So I have this Django application with django-summernote, and I'm having trouble uploading image files via the editor. When I click the upload button and choose an image from my computer, I get an error saying "Failed to save attachment". And in the console, I see this error: "POST /summernote/upload_attachment/ 500". Let me show you my code. settings.py
INSTALLED_APPS = [
...
'django_summernote',
...
]
...
DEBUG = True
...
SUMMERNOTE_CONFIG = {
'iframe': True,
'lang' : 'ko-KR',
'summernote': {
'width': '100%',
'height': '450px',
'placeholder':'First sentence',
'toolbar': [
['style', ['style',]],
['font', ['fontsize', 'bold', 'italic', 'strikethrough']],
['color', ['forecolor', ]],
['para', ['ul', 'ol', 'height']],
['insert', ['link']],
['misc', ['picture', 'fullscreen', 'print', 'help', ]],
],
},
'js': (
'static/summernote-ext-print.js',
),
'js_for_inplace': (
'/static/summernote-ext-print.js',
),
'css': (
'//cdnjs.cloudflare.com/ajax/libs/codemirror/5.40.0/theme/base16-dark.min.css',
'/mvp/static/summernote.css',
),
'css_for_inplace': (
'//cdnjs.cloudflare.com/ajax/libs/codemirror/5.40.0/theme/base16-dark.min.css',
'/summernote.css',
),
'codemirror': {
'theme': 'base16-dark',
'mode': 'htmlmixed',
'lineNumbers': 'true',
},
'lazy': False,
}
SUMMERNOTE_THEME = 'bs4'
X_FRAME_OPTIONS = 'SAMEORIGIN'
...
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
urls.py
urlpatterns = [
path('summernote/', include('django_summernote.urls')),
]
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
I don't see what I've done wrong. Everything else except uploading image works fine. BTW, I'm using Django 3.x and Bootstrap 4.x.
+++ If it gives you any further info: I also keep getting these errors in the console as well. Might be related?
Refused to apply style from '<myURL>/summernote.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

This has been making me so frustrated for days. I'd very much appreciate your help. :)
