django上传文件

2018-08-04

1.model类#

1
2
3

class uploadfile(models.Model):
    title = models.CharField(max_length=50)
    files = models.FileField(upload_to='upload/%Y/%m/%d/',max_length=100)

2.form类#

继承ModelForm类,校验form表单提交的数据,通过form自动保存数据到数据库

class UploadFileForm(forms.ModelForm):
    class Meta:
        model = uploadfile
        fields = "__all__"

3.view 视图#

def login(request):
    files = uploadfile.objects.all()
    return  render(request,"demo.html",{"files":files}) 

def filesimple(request):
    if request.method == 'POST':
        froms = UploadFileForm(request.POST,request.FILES)
        if froms.is_valid():
            froms.save()#自动上传到数据（upload_to 指定的目录）
            handle_upload_file(request.FILES['fileworld'])
            return HttpResponse("上传成功!")
    return  HttpResponse("上传失败!")


还可以通过方式2写入到指定文件
def handle_upload_file(file):
    with open('upload/','wb+') as des:
        for ch in file.chunks(): #chunk方式数据量大
            des.write(ch)

4 路由URL#

1 2	path('login/', views.login,name="login"), path('filesimple/', views.demo,name="demo"),

5 前端HTML#

 <body>
    <div>
        <form method="post" action="/filesimple/" enctype="multipart/form-data" >
        {% csrf_token %}
        <label>标题:</label><input type="text" name="title" /><br />
        <input type="file"   name="files" /><br />
        <input type="submit" value="提交" />
    </form>
    <label>文件列表</label><br />
    <ol>
        {% for file in files %}
            <li>{{ file.files }}</li>
        {% endfor %}
    </ol>
    </div>

</body>
