Create your first application (app)
1. Create an application named under the myproject project
Format : python manage.py startapp app-name
Here, the application (app) is created directly in pycharm, which is the same as the command in cmd. The example of
python manage.py startapp myapp
is as follows :
The contents of the application (app) include the following:
a init .py : initialization
b admin.py : management of the background registration model
c apps.py : needed when registering an app in the settings environment. But it is not recommended to use
d models.py here: the place to write the model
e tests.py:
f urls.py
g views.py: the place to write the business logic
Emphasis : the most used here are d, f and g
Defining methods in views in myapp application
When using HttpResponse here, you need to import the following modules
from django.http import HttpResponse
Define a method for hello_girl
def hello_girl(request):
# 返回一个Hello, beautiful girl的页面对象
return HttpResponse('Hello, beautiful girl')
Configuration of urls under myproject project
1. Configure urlpatterns
from django.conf.urls import url, include
from django.contrib import admin
from myapp import views under the urls file in myproject project
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^myapp/', include(myapp.urls)),
# Here hello_girl is the path, through which you can access the hello_girl method In the Hello, beautiful girl object, pay attention to the / behind hello/, which represents the matching
url of the path (r'^hello_girl/', views.hello_girl),
Configuration of urls under myapp project
2. Create a new urls folder under the myapp project, and configure the urls in
this directory just to match the urls path under the myproject project
from django.conf.urls import url
from myapp import views
urlpatterns = [
url(r'^hello_girl/', views.hello_girl),
]
Visit the page address as follows:
127.0.0.1:8000/myapp/hello_girl/
and it will display: Hello, beautiful girl
