花30分钟教你用Django创建一个照片墙网站

本文只涉及搭建的教程,不涉及VPS、服务器等。转发请注明来源。

-0- 使用到的资源:

  • 前端: Blueimp Gallery
  • 后端: Django
  • 缩略图: easy_thumbnails
  • 部署: nginx + gunicorn + supervisor
  • 开发环境是Centos 7.2 + Python 2.7.5

上个图先:

-1- 创建项目

假设当前用户是ljgabc,当前目录是/home/ljgabc

virtualenv django
source django/bin/activate
pip install django pillow easy_thumbnails gunicorn
django-admin startproject websites
cd websites
python manage.py startapp gallery

-2- 修改配置

首先修改websites/settings.py中的INSTALLED_APPS,添加应用,

INSTALLED_APPS = [
    ...,
    'gallery.apps.GalleryConfig',
    'easy_thumbnails',
]

其它配置如下:

  • 图片文件上传位置: gallery/uploads
  • 图片访问地址: /uploads/xxxx.jpg
  • 缩略图大小为75x75
  • 最终静态文件存放地址为static/
    因此修改websites/settings.py,添加以下内容,
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

MEDIA_ROOT = os.path.join(BASE_DIR, 'gallery')
MEDIA_URL = '/'
IMAGE_PREFIX = 'uploads'

THUMBNAIL_ALIASES = {
  '': {
    '75x75' : {'size': (75,75), 'crop':True},
  },
}

-3- 配置URL

由于我们的网站只有一页,所以需要配置的URL只有//admin/uploads,修改websites/urls.py,配置如下:

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

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', include('gallery.urls')),
]

urlpatterns += static(settings.IMAGE_PREFIX, document_root=os.path.join(settings.MEDIA_ROOT, settings.IMAGE_PREFIX))

添加gallery/urls.py,

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.gallery, name='gallery'),
]

-4- 添加模型

编辑gallery/models.py,添加Image模型,

from django.db import models
from django.conf import settings
from django.utils.encoding import python_2_unicode_compatible

# Create your models here.

@python_2_unicode_compatible
class Image(models.Model):
    '''
    模型包含Title、文件、创建时间等
    '''
    title = models.CharField(max_length=250, blank=True)
    original = models.ImageField(upload_to=settings.IMAGE_PREFIX, default='/tmp/none.jpg')
    created = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title

-5- 添加视图

编辑gallery/views.py,配置视图,

from django.shortcuts import render
from .models import Image
# Create your views here.

def gallery(request):
    image_list = Image.objects.all()
    return render(request, 'gallery/index.html', {
        'image_list': image_list
        })

-6- 添加静态文件

从网上下载Blueimp Gallery文件,将其中的cssimgjs文件夹放入gallery/static/gallery/文件夹下。

-7- 添加首页模板

创建gallery/templates/gallery/index.html,内容如下:

{% load static %}
{% load thumbnail %}


  
    
    
    
    Photo Gallery
    
    
  
  
    
    
    
    
    
  

-8- 初始化

python manage.py makemigrations gallery
python manage.py migrate
python manage.py createsuperuser

-9- 预览

python manage.py runserver 0.0.0.0:8000

-10- 配置supervisor

yum install supervisor

创建/etc/supervisor.d/gallery.ini, 添加以下内容:

[program:gallery]
command=/home/ljgabc/django/bin/gunicorn websites.wsgi:application
directory=/home/ljgabc/websites
user=ljgabc
autostart=true
autorestart=true

启动supervisor,

systemctl start supervisor
# supervisorctl start gallery

此时访问127.0.0.1:8000应该可以看到应用已经启动。

-11- 配置nginx

首先将所有用到的静态文件收集到STATIC_ROOT目录下,

python manage.py collectstatic

创建/etc/nginx/conf.d/gallery.conf,

server {
    listen 80;
    server_name www.your-domain-name.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://127.0.0.1:8000;
    }

    location /static/ {
        root /home/ljgabc/websites;
    }
}

启动nginx

systemctl start nginx
