创建应用
django-admin startproject 项目名字
创建APP
python manage.py startapp APP名字
迁移数据库
python manage.py makemigrations
运行数据库
python manage.py migrate
收集静态文件
python manage.py collectstatic
启动项目
python manage.py runserver
创建超级用户
python manage.py createsuperuser
创建APP以后
settings中增加INSTALLED_APPS, APP内增加分url
python
# 引入path
from django.urls import path
# 正在部署的应用的名称
app_name = 'APP名称'
urlpatterns = [
# 目前还没有urls
]总url引入分url
python
from django.urls import path, include
urlpatterns = [
# 新增代码，配置app的url
path('定义url/', include('APP名称.urls', namespace='APP名称')),
]写API函数
分url
python
from django.urls import path
from APP名称 import views
app_name = 'APP名称'
urlpatterns = [
path('list/',views.hellolist),
]views
python
from rest_framework.decorators import api_view
from rest_framework.response import Response
@api_view(['GET'])
def hellolist(request):
list = [1,2,3,4,5]
return Response(list)时间查询
python
1、gt：大于某个时间
now = datetime.datetime.now()
#前一天
start = now – datetime.timedelta(hours=23, minutes=59, seconds=59)
a=yourobject.objects .filter(youdatetimcolumn__gt=start)
2、gte：大于等于某个时间：
a=yourobject.objects .filter(youdatetimcolumn__gte=start)
3、lt：小于
a=yourobject.objects .filter(youdatetimcolumn__lt=start)
4、lte：小于等于
a=yourobject.objects .filter(youdatetimcolumn__lte=start)
5、range：查询时间段
start_date = datetime.date(2005, 1, 1)
end_date = datetime.date(2005, 3, 31)
Entry.objects.filter(pub_date__range=(start_date, end_date))
6、year：查询某年
Entry.objects.filter(pub_date__year=2005)
7、month：查询某月
Entry.objects.filter(pub_date__month=12)
8、day：某天
Entry.objects.filter(pub_date__day=3)
9、week_day：星期几
Entry.objects.filter(pub_date__week_day=2)
10、获取今天的日期，日期格式为yyyy-MM-dd
from django.utils.timezone import now, timedelta
date = now().date() + timedelta(days=-1) #昨天
date = now().date() + timedelta(days=0) #今天
date = now().date() + timedelta(days=1) #明天部署以后登录后台显示403CSRF
python
# 修改settings.py文件
CSRF_TRUSTED_ORIGINS = [
'https://具体网址',
# 其他可信任的来源
]
