搭建自己的博客（十三）：为博客后台添加ckeditor富文本编辑器

使用django默认的编辑器感觉功能太少了，所以集成一下富文本编辑器。

1、安装和使用

（1）、安装

pip install django-ckeditor

（2）、注册应用

在django的settings中添加‘ckeditor’的app

（3）、配置models

将需要用到富文本编辑器的字段改成RichTextField

上面三步配置过后是不能上传图片的，下面配置上传图片的功能。

（4）、安装pillow库

pip install pillow

（5）、注册应用

添加'ckeditor_uploader'这个app

（6）、在settings指定图片上传的目录

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

# 配置ckeditor
CKEDITOR_UPLOAD_PATH='upload/'

（7）、在urls中指定要上传的网址

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
from . import views

urlpatterns = [
    path('', views.home, name='home'),  # 主页路径
    path('admin/', admin.site.urls),
    path('ckeditor', include('ckeditor_uploader.urls')),  # 配置上传url
    path('blog/', include('blog.urls')),  # 博客app路径
]

# 设置ckeditor的上传
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

（8）、配置model

把字段改成RichTextUploadingField字段类型

（9）、官方文档

上面这几步差不多就行了，还需要扩展功能，前往-》官方文档

2、变化的部分：

3、上代码
