django学习之传列表到前端html页面显示

views.py

def main_page(request):
   data = [1,2,3,4,5,6,7]
   return render(request, 'index1.html',  {'data':data}) #这里传的是字典，字典的键一定要和html页面中的一致

index1.html

    
    


{% for item in data %}
{{ item }}
{% endfor %}

settings.py
在INSTALLED_APPS 的列表加入在apps.py中的类名路径
比如说
apps.py

from django.apps import AppConfig


class Test3AConfig(AppConfig):
    name = 'test3a'

那么得在settings.py加上

'test3a.apps.Test3AConfig',

test3a/apps.py

from django.conf.urls import url, include
from . import views 
urlpatterns = [
   url(r'^$', views.main_page),
#  url(r'^topics/$', views.topics, name='topics'),
]

test.py

"""test3 URL Configuration
