Amazon S3 with Django can't load all the stati

I'm using Amazon S3 to be my static and media files storage. My Django project is running in Digital ocean ubuntu 16.04.

After running python manage.py collectstatic I found the CSS and js did not work in my website. And then I found that the CSS and js hadn't been upload in the S3. I think this is the reason why the cs and js did not work because they are not in there.

there is only 'static' folder in S3.

in this static folder there are not my project static files but the admin xadmin and another plug's static files

Above is the folder under static in S3.

When I check the url of the js it looks like this:

<link rel="stylesheet" href="https://myproject.s3.amazonaws.com/css/main.css?Signature=imJphDmnb4U%2BWOWHjE0Iagk2tow%3D&amp;AWSAccessKeyId=AKIAI4LFEI2ASSMOYRTQ&amp;Expires=1537337559">


<link rel="icon" href="https://myproject.s3.amazonaws.com/images/logo-blue.png?Signature=ACidpeC946mBazTtHx0McVIk6rM%3D&amp;AWSAccessKeyId=AKIAI4LFEI2ASSMOYRTQ&amp;Expires=1537337559">

But in my project the main.css is under static folder, the images are under media folder. This is so weird for me.

This is my project folder looks like:

And I found that, after running python manage.py collectstatic the system didn't copy the static and media at all

Here is the main part of my settings.py:

import os
import sys
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))
sys.path.insert(0, os.path.join(BASE_DIR, 'extra_apps'))


ROOT_URLCONF = 'myproject.urls'


STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static/')

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

AWS_ACCESS_KEY_ID = 'myproject'
AWS_SECRET_ACCESS_KEY = 'myproject'
AWS_STORAGE_BUCKET_NAME = 'myproject'
AWS_S3_FILE_OVERWRITE = False
AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME
# the sub-directories of media and static files
STATICFILES_LOCATION = 'static'
MEDIAFILES_LOCATION = 'media'
# a custom storage file, so we can easily put static and media in one bucket
STATICFILES_STORAGE = 'myproject.custom_storages.StaticStorage'
DEFAULT_FILE_STORAGE = 'myproject.custom_storages.MediaStorage'

# the regular Django file settings but with the custom S3 URLs
STATIC_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, STATICFILES_LOCATION)
MEDIA_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, MEDIAFILES_LOCATION)

I also created a file named custom_storages.py:

from django.conf import settings
from storages.backends.s3boto3 import S3Boto3Storage

class StaticStorage(S3Boto3Storage):
    location = settings.STATICFILES_LOCATION

class MediaStorage(S3Boto3Storage):
    location = settings.MEDIAFILES_LOCATION

This issue is really very complicated to me. Any friend can help? This issue spends me 2 days to solve it.
