文集
- 判断用户是否登录了
- 查询当前用户的所有文集
- 如果用户没有文集，那么给用户添加两个默认文件，随笔和日记本
- 用户新建文集
- 查询文集中的所有文章
- 当前默认显示的文章的标题和内容
客户端: settings.js 定义公共方法获取token值
check_user_login(vm){
// 判断用户是否已经登陆
let token = localStorage.user_token || sessionStorage.user_token;
if(!token){
// 跳转到登陆页面
this.jump_page(vm, "尊敬的游客, 您尚未登陆!请登陆后再进行操作!", "警告","去登陆", "/user/login");
}
return token;

定时发布[扩展知识点]
原理：使用celery完成定时任务！
步骤：
1. 当用户点选了定时发布, 页面中弹出一个选择时间的窗口。
2. 当用户设置完成发布时间以后，点击“确认”以后,把这个时间和文章id发送到服务端。
3. 服务端中文章模型的pub_date记录这个定时发布时间。
4. 在celery中创建一个定时任务，在每个固定时间段，检查文章表中，对应时间段的pub_date把对应的文章进行发布。
1.前端增加一个选择时间的弹窗，

}).then((res)=>{
this.$message.success('定时发布成功')
this.dialogVisible = false
}).catch((error)=>{
this.$message.error('文章定时发布失败！')
})
},
}
}
</script>
2.服务端提供修改pub_date发布时间的api接口
路由article/urls.py：
from django.urls import path,re_path
from . import views
urlpatterns = [
re_path('time_public/(?P<pk>d+)/', views.TimeArticlePublicView.as_view()), # 定时发布
]
视图代码article/views.py：
# 文章定时发布
class TimeArticlePublicView(APIView):
permission_classes = [IsAuthenticated, ]
# 发布文章
def put(self,request,pk):
pub_date = request.data.get('pub_date')
# 将字符串转换成时间戳,发布时间戳
pub_date_timestamp = datetime.timestamp(datetime.strptime(pub_date,'%Y-%m-%d %H:%M'))
# 当前时间戳
now_timestamp = datetime.now().timestamp()
if pub_date_timestamp < now_timestamp:
return Response({'error':'发布时间不能小于当前时间'},status=400)
# 推送feed,给粉丝推送文章
# 获取当前作者的粉丝
ts = TableStore()
# 获取粉丝类表
fans_list = ts.get_author_fans(request.user.id)
if len(fans_list)>0:
# 给每一个粉丝推送feed
ts.push_feed(request.user.id,pk, fans_list)
try:
Article.objects.filter(pk=pk).update(
pub_date=pub_date
)
return Response({'msg':'ok'})
except:
logger.error(f'id为{pk}的文章，发布失败！')
return Response({'msg':'not ok'},status=507)
3.使用celery的定时任务
每分钟执行一次定时发布操作，让pub_date时间到了，则更新对应文章的发布状态。
在mycelery中创建time_article任务目录，在目录下创建任务文件tasks.py，编写异步任务：
from mycelery.main import app
from article.models import Article
from datetime import datetime
@app.task(name='time_public')
def time_public():
# 查询pub_date不为空的，发布时间小于周期任务执行时间的文章
article_list = Article.objects.filter(pub_date__lte=datetime.now()).exclude(pub_date=None)
print(article_list)
for article in article_list:
article.is_public = True
article.save()
注册异步任务到myselery/main.py中。使用celery的定时任务调度器，让celery定时执行异步任务，代码：
from celery import Celery
import os
import django
from django.conf import settings
# 把celery和django进行组合，识别和加载django的配置文件
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'renranapi.settings.dev')
# 对django框架执行初始化
django.setup()
# 实例化对象
app = Celery('renran')
# 加载配置
app.config_from_object('mycelery.config')
# 自动搜索并加载任务
app.autodiscover_tasks(['mycelery.mytasks','mycelery.time_article'])
# 定时任务调度器
app.conf.beat_schedule={
'every_10_seconds':{
'task':'time_public',
# 'schedule': crontab(), # 时间间隔
'schedule':10,
# 'args':(16,16) # 参数
},
}
# 修改时区，和django框架同步时区
app.conf.timezone = settings.TIME_ZONE
Celery官方文档中关于定时任务使用的说明：http://docs.celeryproject.org/en/latest/userguide/periodic-tasks.html
接下来，我们就可以重启Celery并启用Celery的定时任务调度器
先在终端下，运行celery的定时任务程序，以下命令：
celery -A mycelery.main beat # mycelery.main 是celery的主应用文件
然后再新建一个终端，运行以下命令，上面的命令必须先指定：
celery -A mycelery.main worker --loglevel=info
注意，使用的时候，如果有时区必须先配置好系统时区。
文章内容保存
前端ajax节流
现在用户每一次粒度很小的操纵都会导致前端发送一次ajax请求，所以我们可以通过定时器setTimeout来让ajax延时发送请求，例如，当用户进行修改操作时，我们可以调用setTimeout来让ajax2秒发送请求，如果2秒内，用户有继续操作了文章，则重新计算2秒。 这种解决问题的思路，在前端里面叫函数节流/ajax节流。
客户端，代码：writer.vue

服务端提供修改文章内容和标题的api接口。
模型新增一个保存文章内容显示效果的字段render。
class Article(BaseModel):
"""文章模型"""
content = models.TextField(null=True, blank=True, verbose_name="文章内容")
render = models.TextField(null=True, blank=True, verbose_name="文章内容[解析后]")
user = models.ForeignKey(User, on_delete=models.DO_NOTHING, verbose_name="作者")
collection = models.ForeignKey(ArticleCollection, on_delete=models.CASCADE, verbose_name="文集")
pub_date = models.DateTimeField(null=True, default=None, verbose_name="发布时间")
access_pwd = models.CharField(max_length=15, null=True, blank=True, verbose_name="访问密码")
read_count = models.IntegerField(default=0, null=True, blank=True, verbose_name="阅读量")
like_count = models.IntegerField(default=0, null=True, blank=True, verbose_name="点赞量")
collect_count = models.IntegerField(default=0, null=True, blank=True, verbose_name="收藏量")
comment_count = models.IntegerField(default=0, null=True, blank=True, verbose_name="评论量")
reward_count = models.IntegerField(default=0, null=True, blank=True, verbose_name="赞赏量")
is_public = models.BooleanField(default=False, verbose_name="是否发布")
class Meta:
db_table = "rr_article"
verbose_name = "文章"
verbose_name_plural = verbose_name
