python测试开发django-110.ModelForm模型表单上传文件
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
# 作者-上海悠悠 QQ交流群:717225969 # blog地址 https://www.cnblogs.com/yoyoketang/ 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 # 作者-上海悠悠 QQ交流群:717225969 # blog地址 https://www.cnblogs.com/yoyoketang/ 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}), ]
实现效果
访问页面

上传成功返回
复制返回的图片地址，拼接请求可以访问上传的图片http://localhost:8000/media/upload/21_fyErshM.png
