這篇文章主要介紹了Django實現(xiàn)后臺上傳并顯示圖片功能,文中通過示例代碼介紹的非常詳細，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值,需要的朋友可以參考下

1.安裝pillow

pip install Pillow

2.創(chuàng)建app

python manage.py startapp upload

3. project設(shè)定

settings.py

INSTALLED_APPS = [
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'upload.apps.MyuploadConfig', #add this
]

TEMPLATES = [
 {
  'BACKEND': 'django.template.backends.django.DjangoTemplates',
  'DIRS': [os.path.join(BASE_DIR,'templates')],
  'APP_DIRS': True,
  'OPTIONS': {
   'context_processors': [
    'django.template.context_processors.debug',
    'django.template.context_processors.request',
    'django.contrib.auth.context_processors.auth',
    'django.contrib.messages.context_processors.messages',
    'django.template.context_processors.media' #add this
   ],
  },
 },
]

#picture path setting
MEDIA_ROOT = os.path.join(BASE_DIR, 'media').replace("\\", "/")
MEDIA_URL = '/media/'

urls.py

from django.contrib import admin
from django.urls import path,include
from django.conf.urls.static import static
from django.conf import settings


urlpatterns = [
 path('admin/', admin.site.urls),
 path('', views.index),
 path('upload/', include(('myupload.urls', 'myupload'), namespace='myupload')), # add uppoad urls
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)      #add image path

4. app 設(shè)定

models.py

from django.db import models

class User(models.Model):
 name = models.CharField(verbose_name='姓名', max_length=10)
 avator = models.ImageField(verbose_name='頭像', upload_to='upload/%Y/%m/%d')

admin.py

from django.contrib import admin
from .models import *

# Register your models here.
admin.site.register(User)

urls.py

from django.contrib import admin
from django.urls import path, register_converter, re_path
from . import views

urlpatterns = [
 path('', views.index, name='index'), # 上傳首頁
]

views.py

from django.shortcuts import render
from .models import User
from django.http import HttpResponse

# Create your views here.
def index(request):
 users = User.objects.all()return render(request, 'upload/index.html', locals())

5 . 前臺設(shè)定

project 目錄下 templates/upload/index.html

----------------------------------------------------------------------------------------

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Title</title>
</head>
<body>
<ul>
 {% for user in users%}
  <li>{{ user.name }}</li>
  <li><img src="{{ MEDIA_URL }}{{ user.avator }}" alt=""></li>
 {% endfor %}
</ul>
</body>
</html>
