如何使用 django 应用程序在 AWS S3 中上传文件？

我在上传用户个人资料图片时遇到问题。现在，当我在 Django admin 中创建一个用户并从管理仪表板上传文件时，它可以正常工作并且没有错误。它应该进入我的 AWS S3 存储桶，但这显然不可行，我一直在寻找解决方案 3 到 4 天，但没有成功或任何令人满意的结果。我显然不会向用户提供仪表板访问权限。使用的数据库是MongoDB，数据库引擎是djongo。

这是我的settings.py

INSTALLED_APPS = [
    'profileupload',
    's3direct',
    'storages',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.humanize',
]
STATIC_URL = '/static/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
AWS_SECRET_ACCESS_KEY = 'MY_SPECIAL_KEY'
AWS_ACCESS_KEY_ID = 'MY_SPECIAL_KEY_NAME'
AWS_STORAGE_BUCKET_NAME = 'S3_BUCKET'
AWS_S3_FILE_OVERWRITE = False
AWS_DEFAULT_ACL = None
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'

我的网址.py

from django.urls import path, include
from .views import signup_form
urlpatterns = [
    path('signup', signup_form, name='signup'),
]

我的模型.py

class profile(models.Model):
    profile_id = models.AutoField(primary_key=True,unique=True)
    profile_username = models.CharField(max_length=100,unique=True)
    profile_name = models.CharField(max_length=150)
    profile_email = models.EmailField(max_length=200)
    profile_create_time = models.DateField(auto_now_add=True)
    profile_dob = models.DateField()
    profile_password = models.CharField(max_length=50, null=True)
    profile_picture = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return str(self.profile_username)

我的意见.py

def signup_form(request):
    if request.method == 'POST':
        if request.POST.get('profile_username') and request.POST.get('profile_name') and request.POST.get('profile_email') and request.POST.get('profile_dob') and request.POST.get('profile_password') and request.POST.get('profile_picture'):
            pr = profile()
            pr.profile_username = request.POST.get('profile_username')
            pr.profile_name = request.POST.get('profile_name')
            pr.profile_email = request.POST.get('profile_email')
            pr.profile_password = request.POST.get('profile_password')
            pr.profile_dob = request.POST.get('profile_dob')
            pr.profile_picture = request.POST.get('profile_picture')
            try:
                pr.save()
                print('setProfile success')
                return redirect('index.html')
            except Exception as e:
                return render(request, 'signup.html')
            return render(request, 'signup.html') 
    else:
        return render(request, 'signup.html')

我的注册表单“signup.html”

{% extends 'index.html' %}
{% block content %}

<form method='POST'>
    {% csrf_token %}
    <div>
        <label>USERNAME</label>
        <input type="text" placeholder="" name="profile_username" required/>
    </div><br>
    <div>
        <label>NAME</label>
        <input type="text" placeholder="" name="profile_name" required/>
    </div><br>
    <div>
        <label>EMAIL</label>
        <input type="email" placeholder="" name="profile_email" required/>
    </div><br>
    <div>
        <label>Password</label>
        <input type="password" placeholder="" name="profile_password" required/>
    </div><br>
    <div>
        <label>DOB</label>
        <input type="date" placeholder="" name="profile_dob" required/>
    </div><br>
    <div>
        <label>Profile Picture</label>
        <input type="file" placeholder="" name="profile_picture" required/>
    </div><br>
    <button type="submit">submit</button>
</form>
<a href="/">Home</a>
{% endblock content %}

另外，我想更改上传文件的名称，Django 管理员上传的文件采用原样的文件名，但是当我将此应用程序公开时，文件名必须正确，以避免被覆盖或有多次使用同一个文件
