Python uses Jdango to create a Web project complete step __web

First, we use Pycharm to create a Jdango project

The app name, called Jdango_second, creates a good format as shown in the picture:

Two, we create the project is the MTV mode

Model (corresponding database), templates (page display), view (logical processing)

models.py:

From django.db import Models

# Create your models here.
Class Stu (models. Model):
    id = models. Charfield (max_length=16,primary_key=true)
    name=models. Charfield (default= ' dqd ', max_length=16)

views.py:

From django.shortcuts import render to
jdango_second.models import Stu
# Create your views here.
def showinfo (Request):
    stu_list = Stu.objects.all ()
    content = {' list ': Stu_list} return
    render (request, ' Index.html ', content)

In admin.py, the class in models.py is registered:

From django.contrib import Admin to
jdango_second.models import Stu
# Register your models here.
Admin.site.register (STU)

In the __init__.py of the project we can do some initialization (second):

Import Pymysql
pymysql.install_as_mysqldb ()

db = Pymysql.connect ("localhost", ' root ', ', ', ' Py_second ')

cursor = Db.cursor ()

cursor.execute (' SELECT version () ')

data = Cursor.fetchone ()

print ("VERSION is%s"% Data)

Db.close ()

Also in the setting.py of the project we set up the linked database and the path to the static path and templates:

"" "Django settings for second project.

The path to the configuration browser address bar in the project's urls.py corresponds to the function name in views.py:

From django.conf.urls import URL from
django.contrib import admin from
jdango_second.views import Showinfo

Urlpatterns = [
    url (R ' ^admin/', admin.site.urls),
    url (r ' ^index/', showinfo),
]

Static paths are used to place a variety of statically files, such as:

Static

Img

1.png

Js

Css

The path to templates is:

Templates

Index.html

Index.html:

<! DOCTYPE html>
{% load staticfiles%}
