借我杀死庸碌的情怀

初学者，一切都是个开始和摸索

To learn Django step by step.

001：Django：web框架的学习002：Django：web框架的学习(2)

核心知识：

再次强化开发步骤和知识
简易的HTML和CSS语法
数据库操作
模板的使用

1: 目标

先显示最终效果图：这是个包含背景颜色的网页，不是水印。

Wechat : 显示微信账号
Weibo：直接跳转至微博平台
Github: 直接跳转至Github平台
简书：直接跳转至简书平台
更多：跳转至抓取的豆瓣电影Top250，后页面显示的部分：

2：重申开发步骤

创建APP
编辑视图文件
配置url
编辑模型文件定义数据库
编辑模板文件

3：定义数据库文件

账号数据表：对应于：wechat, 简书，github 等

class Message(models.Model):    Id_name = models.CharField(max_length=10)    Id_user = models.CharField(max_length=10)    Id_url = models.CharField(max_length=60)    Id_des = models.TextField(max_length=60)    def __str__(self):        return self.Id_user# 包含名称，账号，链接，介绍几个字段

电影数据：这里不讲述数据如何抓取：爬虫看这里

class Film(models.Model):    Film_name = models.CharField(max_length=20)    Film_director = models.CharField(max_length=10)    Film_rate = models.FloatField(max_length=5)    Film_number = models.CharField(max_length=10)    Film_url = models.CharField(max_length=30)    Film_describe = models.TextField(max_length=60)    def __str__(self):        return self.Film_name# 定义5个字段和相应数据类型## 确保上述数据表中存在数据

4：模板文件

模板文件都是些前端知识，好吧，我不太会...

大致的内容有：

HTML的元素，属性，结构之类的
CSS层叠样式：修饰HTML文件中的内容的形式

举例：

HTML

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>谢小路</title></head><div></div><body><h1 id="Hello-world">Hello world!</h1></body></html># HTML文件长这样.

CSS

nav{  background-color: #000000;  height: 50px;}#banner{  background: #CCCCCC;  height: 600px;}# 定义了背景颜色和高度# HTML 和CSS配合使用提升开发效率...

Django中的使用新建一个文件夹专门存放模板文件，命名为templates,文件夹下可以创建文件夹以APP名称存放模板文件这里我创建了两个APP，一个名为one,一个为two其中one/film.html文件下显示的是：上文中更多显示的电影数据two/index.html文件显示的是：首页信息，即上文第一张图显示

|---templates|---templates/one/film.html|---templates/two/index.html

设置模板文件路径setting.py

TEMPLATES_DIR = (  os.path.join(BASE_DIR, 'templates/one/'),  os.path.join(BASE_DIR, 'templates/two/'),)

为了显示电影数据：修改one下的视图文件：views.py , film.html模板文件

def film(request):    film = Film.objects.order_by("id")    return render(request, 'one/film.html', {"Film": film})    pass

为了显示账户信息等数据：修改two下视图文件：views.py index.html模板文件

def des(request):    message = Message.objects.order_by("id")    return render(request, 'two/index.html' , {"Message": message})

配置url

urlpatterns = [    url(r'^admin/', admin.site.urls),    url(r'^film', film), # 这个显示电影数据    url(r'', des),  # 这个显示首页信息]

5. Django常用指令

django-admin.py startproject [filename] # 创建新项目
python manage.py runserver # 启动web服务
python manage.py startapp [APPNAME] # 创建web APP
python manage.py makemigrations
python manage.py migrate
python manage.py shell
python manage.py createsuperuser # 创建后台超级用户

6. 编程感悟

如果不是你遇到的实际问题，看任何实际的文章都存在着知识的盲区。

想要把一个东西说出来和写出来，和你感觉会，不是一码事。

这是个需要不断更新知识的时代，每天都存在着接触或者被动接触新东西，需要抓住自己的知识体系不断构建，不然易陷入贪多还不会的地步。

学会一点技术，重复是个少不了的技能。

摸索需要极大的成本，假如身边有牛人，千万别放过学习的机会...
