django之创建第10-1个项目-图片上传并记录上传时间

2、主要修改的配置文件有3个，forms、views和models3个文件以及html

3、forms.py文件修改

#coding:utf-8

#这里定义html页面中用到的表单，常和views和models文件配合使用

#从django导入forms类

from django import forms

class UserForm(forms.Form):

    #intime = forms.DateField()#注释掉intime变量，因为html中不需要操作该项，该项为自动输入

    username = forms.CharField()

    headImg = forms.FileField()

4、models文件

#coding:utf-8

from django.db import models

class User(models.Model):

    intime = models.DateTimeField()

    username = models.CharField(max_length = 30)

    headImg = models.FileField(upload_to = './photos/')

    #图片上传之后存放在./photos/目录下，站点根目录下的photos目录中

    #./代表站点根目录，../代表当前目录的上一级目录

    class Meta:

        db_table = 'User'

    def __unicode__(self):

        return self.username

    #username 用户存放用户名，headImg 用户存放上传文件的路径

5、views文件

# Create your views here.

#coding:utf-8

from django.http import HttpResponse

import datetime

#导入templates文件所需导入库

from django.template import loader,Context

#引入Student等模块

from blog.models import *

from blog.forms import UserForm

from django.shortcuts import render,render_to_response

def upload(request):

    if request.method == "POST":

        uf = UserForm(request.POST,request.FILES)

        if uf.is_valid():

            #获取表单信息

            username = uf.cleaned_data['username']

            headImg = uf.cleaned_data['headImg']

            #intime = uf.cleaned_data['intime'] #不从表单获取数据,所以注释掉

            #写入数据库

            user = User()

            user.username = username

            user.headImg = headImg

            #自动获取日期时间

            now=datetime.datetime.now()

            myNow=now.strftime('%Y-%m-%d %H:%M:%S')#时间，精确到秒

            #myNow = now.strftime('%Y-%m-%d')#日期，精确到天

            #将当前时间写入intime变量中

            user.intime = myNow

            user.save()

            return HttpResponse('upload ok!')

    else:

        uf = UserForm()

    return render_to_response('upload.html',{'uf':uf})

5、urls文件配置

6、配置setting文件

TEMPLATE_DIRS = (

    # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".

    # Always use forward slashes, even on Windows.

    # Don't forget to use absolute paths, not relative paths.

    '/helloworld/blog/templates'

)

#MEDIA_ROOT是用户上传的文件存储的位置，是文件系统上的路径,

#FileField, ImageField里面的upload_to的相对路径就是相对于MEDIA_ROOT的。

MEDIA_ROOT = 'C:/djangoweb/helloworld/upload'

# URL that handles the media served from MEDIA_ROOT. Make sure to use a

# trailing slash.

# Examples: "http://example.com/media/", "http://media.example.com/"

MEDIA_URL = '/upload/'

7、修改upload.HTML

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

    <title>图片上传功能</title>

</head>

<body>

<h1>图片上传功能</h1>

<form method="post" enctype="multipart/form-data" >

{{uf.as_p}}

<input type="submit" value="ok"/>

</form>

</body>

</html>
