CKEditor富文本编辑器

富文本即具备丰富样式格式的文本。在运营后台，运营人员需要录入课程的相关描述，可以是包含了HTML语法格式的字符串。为了快速简单的让用户能够在页面中编辑带html格式的文本，我们引入富文本编辑器。

 

富文本编辑器：ueditor、ckeditor、kindeditor

1. 安装

pip install django-ckeditor

2. 添加应用

在INSTALLED_APPS中添加

INSTALLED_APPS = [
    ...
    'ckeditor',  # 富文本编辑器
    'ckeditor_uploader',  # 富文本编辑器上传图片模块
    ...
]

3. 添加CKEditor设置

在settings/dev.py中添加

# 富文本编辑器ckeditor配置
CKEDITOR_CONFIGS = {
    'default': {
        'toolbar': 'full',  # 工具条功能
        'height': 300,      # 编辑器高度
        # 'width': 300,     # 编辑器宽
    },
}
CKEDITOR_UPLOAD_PATH = ''  # 上传图片保存路径，留空则调用django的文件上传功能
View Code

4. 添加ckeditor路由

在总路由中添加

path(r'^ckeditor/', include('ckeditor_uploader.urls')),

5. 为模型类添加字段

ckeditor提供了两种类型的Django模型类字段

  • ckeditor.fields.RichTextField 不支持上传文件的富文本字段
  • ckeditor_uploader.fields.RichTextUploadingField 支持上传文件的富文本字段\

修改course/models.py里面的字段信息,记得要重新数据迁移

from ckeditor_uploader.fields import RichTextUploadingField
class Course(models.Model):
    """
    专题课程
    """
    ...
    
    brief = RichTextUploadingField(max_length=2048, verbose_name="课程概述", null=True, blank=True)

vue-video

因为接下来的组件中使用了vue-video视频播放组件，所以我们需要先预安装。

安装依赖

npm install vue-video-player --save

在main.js中注册加载组件

require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);

Detail.vue组件中内置vue-video播放器，代码：

 

分四个步骤：

  1. 通过import 导入videoPlayer组件

  2. 在vue组件中的components，注册播放器组件

  3. 在html中调用videoPlayer

  4. 在data中配置播放器的相关参数

模型中针对 难度登记返回文本内容而不是等级数值

    level_choices = (

    @property
    def level_name(self):
        '''难度等级的文本格式'''
        return self.level_choices[self.level][1]

 

 序列化器代码:

 

# 把原来的讲师序列化器增加几个字段

    class Meta:
        model = Course
        fields = ["id","name","course_img","course_video","students","lessons","pub_lessons","price","teacher","brief","level_name"]

from .serializers import CourseRetrieveModelSerializer
class CourseRetrieveAPIView(RetrieveAPIView):
    queryset = Course.objects.filter(is_delete=False, is_show=True)
    serializer_class = CourseRetrieveModelSerializer
