Django博客重构教程（⼀）models模型设计这⾥主要是三张表Tag、Category、Post，关于评论，后⾯再加

from django.urls import path
from blogproject import views
身上长红痣
from rest_framework import routers
from django.views.decorators.csrf import csrf_exempt
app_name = 'blogproject'
urlpatterns = [
url(r'^post/(?P<article_id>[0-9]+)/(?P<url_slug>[-\w]+)/$', views.post_detail, name='post'), ]
模型⽣成和迁移
python3 manage.py makemigrations
python3 manage.py migrate
这⾥如果发⽣问题的话，把app下migrations⾥的initial.py和所有迁移记录的py⽂件都删掉，然后在django-migrations⾥把对应的初始化initial操作记录删掉，然后重新执⾏makemigrations和migrate
