以下学习朔宁夫基于pycharm的网站开发课程笔记。

富文本：

models： content = models.TextField(verbose_name="content")

或者 content = RichTestUploadingField(default="", verbose_name="content")

setting: installed_app: "ckeditor", "ckeditor_uploader", # 富文本编辑器富文本上传工具

CKEDITOR_CONFIGS = { 'default': { 'toolbar': 'full', 'height': 300, 'width': 800 } }

CKEDITOR_UPLOAD_PATH = os.path.join(BASE_DIR, 'static')

STATIC_URL = '/static/'

STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')]

图片：

models： content = models.ImageField(upload_to='b_i', verbose_name='i') # 会找media路径、创建上传的文件

setting: MEDIA_ROOT = os.path.join(BASE_DIR, 'static')

演示：

一个图文博客：

架构：

主页+详情页。模型：blog。视图类：展示目录+展示详情。

实现：

0 准备富文本工具，资源路径。

INSTALLED_APPS = [
    'ckeditor',
    'ckeditor_uploader',
]

CKEDITOR_CONFIGS = {
    'default': {
        'toolbar': 'full',
        'height': 300,
        'width': 800
    }
}

CKEDITOR_UPLOAD_PATH = os.path.join(BASE_DIR,'static')

STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
]

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

1 创建模型。admin注册。后台添加测试数据。

from django.db import models

from ckeditor_uploader.fields import RichTextUploadingField
from ckeditor.fields import RichTextField


class Blog(models.Model):
    title = models.CharField(max_length=32, unique=False, verbose_name='title')
    abstract = RichTextUploadingField(max_length=64, verbose_name='abstract')
    content = RichTextField(default='', verbose_name='content')
    img = models.ImageField(upload_to='blog_img', verbose_name='img', blank=True)

    class Meta:
        db_table = 'Blogs'
        verbose_name = 'a blog_app'
        verbose_name_plural = 'blogs'

    def __str__(self):
        return f"{self.pk}__{self.title}"

    @classmethod
    def get_one(cls, pk):
        try:
            return cls.objects.get(pk=int(pk))
        except cls.DoesNotExist:
            return None

2 视图类

from django.shortcuts import render
from django.views import View

from blog_app.models import Blog


class BlogHome(View):
    def get(self, request):
        blogs = Blog.objects.all()

        return render(self.request, 'bloghome.html', locals())


class BlogDetail(View):
    def get(self, request, blog_id):
        blog = Blog.get_one(pk=blog_id)
        return render(self.request, 'blogdetail.html', locals())
