当Django在处理文件上传的时候，文件数据被保存在request.FILES
FILES中的每个键为<input type="file" name="" />中的name
注意：FILES只有在请求的方法为POST 且提交的<form>带有enctype="multipart/form-data" 的情况下才会包含数据。否则，FILES 将为一个空的类似于字典的对象
使用模型处理上传文件：将属性定义成models.ImageField类型
pic=models.ImageField(upload_to=‘cars/‘)
pip install Pillow==3.4.1
图片存储路径
MEDIA_ROOT=os.path.join(BASE_DIR,"static/media")
前端代码
<html> <head> <title>文件上传</title> </head> <body> <form method="post" action="upload/" enctype="multipart/form-data"> <input type="text" name="title"><br> <input type="file" name="pic"/><br> <input type="submit" value="上传"> </form> </body> </html>
视图处理逻辑
from django.conf import settings def upload(request): if request.method == "POST": f1 = request.FILES[‘pic‘] fname = ‘%s/cars/%s‘ % (settings.MEDIA_ROOT,f1.name) with open(fname, ‘w‘) as pic: for c in f1.chunks(): pic.write(c) return HttpResponse("ok") else: return HttpResponse("error")
通过使用startproject创建的项目模版中，默认Admin被启用
python manage.py createsuperuser
然后按提示填写用户名、邮箱、密码
from django.contrib import admin from models import * admin.site.register(HeroInfo)
class HeroAdmin(admin.ModelAdmin): ...
admin.site.register(HeroInfo,HeroAdmin)
@admin.register(HeroInfo) class HeroAdmin(admin.ModelAdmin):
class HeroAdmin(admin.ModelAdmin): actions_on_top = True actions_on_bottom = True
在models.py文件中 from django.db import models from tinymce.models import HTMLField from django.utils.html import format_html class HeroInfo(models.Model): hname = models.CharField(max_length=10) hcontent = HTMLField() isDelete = models.BooleanField() def hContent(self): return format_html(self.hcontent) 在admin.py文件中 class HeroAdmin(admin.ModelAdmin): list_display = [‘hname‘, ‘hContent‘]
在models.py中HeroInfo类的代码改为如下： def hContent(self): return format_html(self.hcontent) hContent.admin_order_field = ‘hname‘
在models.py中为HeroInfo类增加方法hName： def hName(self): return self.hname hName.short_description = ‘姓名‘ hContent.short_description = ‘内容‘ 在admin.py页中注册 class HeroAdmin(admin.ModelAdmin): list_display = [‘hName‘, ‘hContent‘]
class HeroAdmin(admin.ModelAdmin): ... list_filter = [‘hname‘, ‘hcontent‘]
class HeroAdmin(admin.ModelAdmin): ... list_per_page = 10
class HeroAdmin(admin.ModelAdmin): ... search_fields = [‘hname‘]
方法
创建视图pagTest：
from django.core.paginator import Paginator def pagTest(request, pIndex): list1 = AreaInfo.objects.filter(aParent__isnull=True) p = Paginator(list1, 10) if pIndex == ‘‘: pIndex = ‘1‘ pIndex = int(pIndex) list2 = p.page(pIndex) plist = p.page_range return render(request, ‘booktest/pagTest.html‘, {‘list‘: list2, ‘plist‘: plist, ‘pIndex‘: pIndex})
配置url：
url(r‘^pag(?P<pIndex>[0-9]*)/$‘, views.pagTest, name=‘pagTest‘),
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<ul>
{%for area in list%}
<li>{{area.id}}--{{area.atitle}}</li>
{%endfor%}
</ul>
{%for pindex in plist%}
{%if pIndex == pindex%}
{{pindex}}
{%else%}
<a href="/pag{{pindex}}/">{{pindex}}</a>
{%endif%}
{%endfor%}
</body>
</html>
