介紹： django項目開發必須懂的知識點，下面使用的數據庫是mysql ,html

models.py 數據庫表結構，python

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models

# Create your models here.

class Test(models.Model):

    name = models.CharField(max_length=20)

一、GET 請求：mysql

urls.pysql

"""pythondjango URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url
from django.contrib import admin
from BlogDjango import views
from polls import views as pollsviews, search, search2

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello/+\d', views.hello),
    url(r'^base/', views.base),
    url(r'^testdb$', pollsviews.testdb),
    url(r'^querydb$', pollsviews.selectDB),
    url(r'^updateDB$', pollsviews.updateDB),
    url(r'^deleteDB$', pollsviews.deleteDB),
    url(r'^search-form$', search.search_form),
    url(r'^search$', search.search),
    url(r'^search-post$', search2.search_post),
]


新建一個search.py

# -*- coding: utf-8 -*-

from django.http import HttpResponse
from django.shortcuts import render_to_response


# 表單
def search_form(request):
    return render_to_response('search_form.html')


# 接收請求數據
def search(request):
    request.encoding = 'utf-8'
    print request.GET
    if 'q' in request.GET:
        message = '你搜索的內容爲: ' + request.GET['q']
    else:
        message = '你提交了空表單'
    return HttpResponse(message)


建立一個頁面

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>菜鳥教程(runoob.com)</title>
</head>
<body>
    <form action="/search" method="get">
        <input type="text" name="q">
        <input type="submit" value="搜索">
    </form>
</body>
</html>

結果：
一、

二、數據庫

二、POST請求（重要）django

注意：請求以後，通過咱們本身的邏輯處理後，如何返回到頁面而且解析：

新建一個search2.py

# -*- coding: utf-8 -*-

from django.shortcuts import render
from django.views.decorators import csrf


# 接收POST請求數據
def search_post(request):
    ctx = {'rlt': 10000}
    print request.POST
    if request.POST:
        ctx['rlt'] = request.POST['q']
    return render(request, "post.html", ctx)
