• Django文件上传【单个/多个图片上传】


    准备工作

    python:3.6.8
    django:2.2.1
    

    新建django项目

     确定项目名称、使用的虚拟环境【当然这个也可以后期修改】、app的名称

    创建成功,选择在新的窗口中打开

    图片上传

    修改配置文件DjangoFileUpload/settings.py

    MEDIA_URL = '/media/'
    MEDIA_ROOT = os.path.join(BASE_DIR, 'media').replace('\', '/')    #media即为图片上传的根路径

     添加表模型FileUpload/models.py

    from django.db import models
    
    class Img(models.Model):
        img_url = models.ImageField(upload_to='photos/',blank=True,null=True) #指定图片上传路径,即media/photos/

    数据迁移

     增加图片上传的路由 DjangoFileUpload/urls.py

    from django.contrib import admin
    from django.urls import path
    from fileUpload import views
    
    urlpatterns = [
        path('admin/', admin.site.urls),
        path(r'uploadImg/',views.uploadImg,name='uploadImg'),
    ]

     增加图片上传的视图 views.py

    from .models import Img
    
    #图片上传
    def uploadImg(request):
        if request.method == 'POST':
            img = Img(img_url=request.FILES.get('img'))
            img.save()
        return render(request, 'imgUpload.html')

    新增页面templates/imgUpload.html

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>图片上传</title>
    </head>
    <body>
        <form action="" method="post" enctype="multipart/form-data">
            {% csrf_token %}
            <input type="file" name="img">
            <input type="submit" value="上传">
        </form>
    </body>
    </html>

    项目启动

    ===============================分割线  多图上传===============================

    1 修改imgUpload.html 

    把<input type="file" name="img">
    改成<input type="file" name="img" multiple="">,就这一处而已,其他都不动
    

    2 views.py

    from DjangoFileUpload.settings import BASE_DIR

    def uploadImg(request): files = request.FILES.getlist('img') for f in files: destination = open(BASE_DIR + '/media/photos/' + f.name,'wb+') #上传的文件都放到/media/photos/文件夹里 for chunk in f.chunks(): destination.write(chunk) destination.close() return render(request, 'imgUpload.html')  

    OK 多图上传已经完成
