前言

django开发页面上的文件上传功能

模型

models.py 设计数据模型，upload_to参数是指定文件上传的路径

class Upfile(models.Model):
    """上传文件"""
    file = models.FileField(upload_to="upload")
    title = models.CharField(max_length=30)
    timestamp = models.DateTimeField(auto_now_add=True)

在setting中添加2个参数,文件上传到项目的media目录

MEDIA_URL = '/media/'

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

视图功能

post提交数据的时候，通过request.FILES 获取文件参数

from .models import Upfile
from django.views import View
from django import forms

class UpFileModelForm(forms.ModelForm):
    """上传文件"""
    class Meta:
        model = Upfile
        fields = ["file", "title"]

class UpFileModelView(View):

    def get(self, request):
        form_obj = UpFileModelForm()
        return render(request, "upfile.html", locals())

    def post(self, request):
        form_obj = UpFileModelForm(request.POST, request.FILES)
        if form_obj.is_valid():
            f = form_obj.save()
            msg = "保存成功"
            return JsonResponse({"code": 0, "msg": "success", "data": "/media/"+str(f.file)})

        else:
            msg = "参数不合法"

        return render(request, "upfile.html", locals())

模板

form表单需设置enctype="multipart/form-data"属性

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<body>
<form action="" method="POST" id="detail-form" enctype="multipart/form-data">
    {% csrf_token %}
    {% for field in form_obj %}
        <p>
            {{ field.label_tag }}
            {{ field }}
            {{ field.errors }}
        </p>

    {% endfor %}
    <p>
        {% if msg %}
            {{ msg }}

        {% endif %}

    </p>
    <p>
        <input type="submit" value="提交" >
    </p>
</form>
</body>
</body>
</html>

urls.py设置访问地址

from django.conf.urls import url
from django.views.static import serve
from . import settings

urlpatterns = [

    url('^upimage$', views.UpFileModelView.as_view()),
    url(r'^media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}),
]
