Django+xadmin实现后台和表单上传图片

简单的演示下，Djang+xadmin上传图片的步骤

前提：请自行创建Django项目和配置xadmin

完整的代码路径：https://github.com/ylpxzx/Django_imageupload

这里我们采用StdImageField来实现图片上传

创建好Django app应用，这里我创建的是名为project的项目和名为password的应用

以下是目录结构

在project目录下创建media目录，用于存放上传的图片，再在media中创建image目录

创建好media目录结构后，在setting.py文件中配置media路径 MEDIA_URL="/media/" MEDIA_ROOT=os.path.join(BASE_DIR,"media") CKEDITOR_UPLOAD_PATH="article_images" 定义password应用的模型文件（models.py） from django.db import models from stdimage.models import StdImageField # Create your models here. class Password(models.Model): appname=models.CharField(max_length=25,verbose_name="备注") user=models.CharField(max_length=30,verbose_name="用户名") email=models.EmailField(verbose_name="Email") phone=models.CharField(max_length=12,verbose_name="手机号") password=models.CharField(max_length=50,verbose_name="密码") created_time=models.DateTimeField(auto_now_add=True,editable=False,verbose_name="创建时间") image1 = StdImageField( upload_to='image/%Y/%m', variations={'thumbnail': {'width': 100, 'height': 75}}, verbose_name=u"图片", ) class Meta: verbose_name=verbose_name_plural="密码管理" def image_img1(self): if self.image1: return str('<img src="%s" />' % self.image1.thumbnail.url) else: return '上传图片' image_img1.short_description = '图片' image_img1.allow_tags = True # 列表页显示图片

 

在setting.py文件的INSTALLED_APPS中分别添加’password‘和’stdimage‘ INSTALLED_APPS = [ 'project', 'password', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'xadmin', 'crispy_forms', 'stdimage', ] 在setting.py中配置mysql数据库（记得要提前在MySQL中创建好ibm_project1数据库） DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'ibm_project1', 'USER': 'root', 'PASSWORD': '自己数据库的密码', 'HOST': '127.0.0.1', 'PORT': '3306', 'OPTIONS': {'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", 'charset': 'utf8', }, } } 在主url.py中(和setting.py同路径)添加

url(r'media/(?P<path>.*)$', serve, {"document_root": MEDIA_ROOT}),

如下所示

from project.settings import MEDIA_ROOT import xadmin from django.conf import settings from django.views.static import serve from django.contrib import admin from django.conf.urls import url from django.urls import path from password.views import Password_list,Password_detail,Password_forms,index urlpatterns = [ url(r'^$', index, name='index'), url(r'^password/$', Password_list, name='password'), url(r'^password/(?P<password_id>\d+)/$', Password_detail, name="detail_password"), url(r'^xadmin/', xadmin.site.urls, name='xadmin'), url(r'media/(?P<path>.*)$', serve, {"document_root": MEDIA_ROOT}), url(r'^password_form/$', Password_forms, name='password_form'), ] 接下来就是配置adminx文件（配置password应用的adminx.py文件，这里的adminx.py文件是配置成功xadmin后的文件） import xadmin from .models import Password from xadmin.layout import Row,Fieldset # Register your models here. @xadmin.sites.register(Password) class PasswordAdmin(object): save_on_top = True actions_on_top = True actions_on_bottom = True form_layout=( Fieldset( '密码信息', 'appname', Row("user", "password"), Row ('email','phone'), ), ) list_display = ('appname', 'user', 'email', 'phone', 'password', 'created_time','image_img1') list_filter = ['appname', 'created_time'] def has_delete_permission(self, *args, **kwargs): return True 最后记得进行数据迁移（终端执行python manage.py makemigrations和python manage.py migrate命令）结果：

点击增加密码管理，就可以进行图片的上传了

以上的就是后台上传图片

下面我们来实现表单上传图片

在password中创建forms.py文件 from django import forms from .models import Password class PasswordForm(forms.ModelForm): def clean_phone(self): cleaned_data=self.cleaned_data['phone'] if not cleaned_data.isdigit(): raise forms.ValidationError('必须是数字!') return int(cleaned_data) class Meta: model=Password fields=( 'appname','user','email','phone','password','image1' ) 接下来就是视图（views.py）的配置 from django.shortcuts import render from django.http import HttpResponseRedirect from django.urls import reverse from .forms import PasswordForm from .models import Password from django.shortcuts import get_object_or_404 # Create your views here. def index(request): return render(request,'index.html') def Password_list(request): password=Password.objects.all() return render(request, 'password.html', context={'passwords':password}) def Password_detail(request,password_id): detail_passwords=get_object_or_404(Password,pk=password_id) return render(request,'password_detail.html',context={'detail_passwords':detail_passwords}) def Password_forms(request): password = Password.objects.all() if request.method == 'POST': form = PasswordForm(request.POST,request.FILES) if form.is_valid(): form.save() return HttpResponseRedirect('/password/') else: form = PasswordForm() context = { 'passwords': password, 'form': form, } return render(request, 'password_form.html', context=context) 配置url from project.settings import MEDIA_ROOT import xadmin from django.conf import settings from django.views.static import serve from django.conf.urls import url from password.views import Password_list,Password_detail,Password_forms,index urlpatterns = [ url(r'^$', index, name='index'), url(r'^password/$', Password_list, name='password'), url(r'^password/(?P<password_id>\d+)/$', Password_detail, name="detail_password"), url(r'^xadmin/', xadmin.site.urls, name='xadmin'), url(r'media/(?P<path>.*)$', serve, {"document_root": MEDIA_ROOT}), url(r'^password_form/$', Password_forms, name='password_form'), ] 结果：
