Django 基本设置

建立django目录，为了独立区分app和主站的关系，需要把app完全和主站分离

app/views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect,HttpResponse
import os
from app.forms import MomentForm
from django.core.urlresolvers import reverse
from django.shortcuts import render

# Create your views here.
def moments_input(request):
    if request.method =='POST':
        form = MomentForm(request.POST)
        if form.is_valid():
            moment = form.save()
            moment.save()
            return HttpResponseRedirect(reverse('welcome'))#reverse连接urls内的name值，来进行反向查找网址
    else:
        form = MomentForm()
    PROJECT_ROOT = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    return render(request,os.path.join(PROJECT_ROOT,'app/templates','moments_input.html'),{'form':form}) #连接到模版文件路径

def welcome(request):

    return HttpResponse('HELLO')

app/urls.py管理app中的url映射

#！/usr/bin/env python
# -*- coding:utf-8 -*-
from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'moments_input',views.moments_input),
    url(r'wc',views.welcome,name='welcome'),# 添加name值，以便于reverse查找
]

django/urls.py

from django.conf.urls import url
from django.contrib import admin
from django.conf.urls import include
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^app/', include('app.urls')), # 建立与app/urls的路由建立连接关系
]

app.models.py 建立模型

# _*_ coding: utf-8 _*_
from django.db import models

# Create your models here.

KIND_CHOICES = (
    ('python技术','python技术'),
    ('数据库技术','数据库技术'),
    ('经济学','经济学'),
    ('文体资讯','文体资讯'),
    ('个人心情','个人心情'),
    ('其他','其他'),
)

class Moment(models.Model):
    content = models.CharField(max_length=200)
    user_name = models.CharField(max_length=20,default='匿名')
    kind = models.CharField(max_length=20,choices=KIND_CHOICES,default=KIND_CHOICES[0])

定义表单类app/form.py

#！/usr/bin/env python
# -*- coding:utf-8 -*-
from django.forms import ModelForm
from app.models import Moment

class MomentForm(ModelForm):
    class Meta:
        model = Moment  # 连接数据库与表单的关系
        fields = '__all__' # 导入所有字段

创建模版文件app/templates/moments_input.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>消息输入页面</title>
</head>
<body>
<form action="?" method="post">
    <fieldset>
        <legend>请输入并提交</legend>
        {{ form.as_p }}
        <input type="submit" value="submit"/>
    </fieldset>
</form>
</body>
</html>

使用自带管理界面app/admin.py

from django.contrib import admin

# Register your models here.
from .models import Moment

admin.site.register(Moment)
