1.管理数据表

（1)修改admin.py文件

1 from .models import Grades,Students
2 #注册
3 admin.site.register(Grades)
4 admin.site.register(Students)

(2)自定义管理页面

 1 from django.contrib import admin
 2 
 3 # Register your models here.在这里注册你的模型
 4 from .models import Grades,Students
 5 #注册
 6 class GradesAdmin(admin.ModelAdmin):
 7     #列表页的属性
 8     list_display = ['pk','gname','gdate','ggirlnum','gboynum','isDelete']#显示字段
 9     list_filter = ['gname']#过滤字段
10     search_fields = ['gname']#搜索字段
11     list_per_page = 5#分页
12     #添加页、修改页属性
13     #fields = ['ggirlnum','gboynum','gname','gdate','isDelete']#规定属性的先后顺序
14     fieldsets = [
15         ("num",{"fields":['ggirlnum','gboynum']}),
16         ("base", {"fields": ['gname','gdate','isDelete']}),
17     ]#给属性分组
18    #fields和fieldsets两个属性不可以同时使用
19 admin.site.register(Grades,GradesAdmin)
20 admin.site.register(Students)

 关联对象要求：在创建一个班级的时候可以直接添加几个学生

 1 from .models import Grades,Students
 2 #注册
 3 #添加关联对象
 4 class StudentsInfo(admin.TabularInline):     #StackedInline可以替换TabularInline区别是添加页面排版不同
5 model = Students#添加学生个人信息 6 extra = 2#添加两个  7 class GradesAdmin(admin.ModelAdmin):  8 inlines = [StudentsInfo]#与学生关联  9 #列表页的属性 10 list_display = ['pk','gname','gdate','ggirlnum','gboynum','isDelete']#显示字段 11 list_filter = ['gname']#过滤字段 12 search_fields = ['gname']#搜索字段

运行如图所示：

 布尔值显示问题

1 class StudentsAdim(admin.ModelAdmin):
2     def gender(self):#把布尔值显示为文字
3         if self.sgender:
4             return "男"
5         else:
6             return "女"
7     #设置页面列的名称
8     gender.short_description = "性别"
      list_display = ['pk','sname','sage',gender,'scontend','sgrade','isDelete']
 

执行动作位置问题

 1 class StudentsAdim(admin.ModelAdmin):
 2     def gender(self):#把布尔值显示为文字
 3         if self.sgender:
 4             return "男"
 5         else:
 6             return "女"
 7     #设置页面列的名称
 8     gender.short_description = "性别"
 9 
10     list_display = ['pk','sname','sage',gender,'scontend','sgrade','isDelete']
11     list_per_page = 10
12     #执行动作的位置
13     actions_on_top = False
14     actions_on_bottom = True
15 admin.site.register(Students,StudentsAdim)

补充此时admin.py中的完整代码为

 1 from django.contrib import admin
 2 
 3 # Register your models here.在这里注册你的模型
 4 from .models import Grades,Students
 5 #注册
 6 #添加关联对象
 7 class StudentsInfo(admin.TabularInline):
 8     model = Students#添加学生个人信息
 9     extra = 2#添加两个
10 class GradesAdmin(admin.ModelAdmin):
11     inlines = [StudentsInfo]#与学生关联
12     #列表页的属性
13     list_display = ['pk','gname','gdate','ggirlnum','gboynum','isDelete']#显示字段
14     list_filter = ['gname']#过滤字段
15     search_fields = ['gname']#搜索字段
16     list_per_page = 5#分页
17     #添加页、修改页属性
18     #fields = ['ggirlnum','gboynum','gname','gdate','isDelete']#规定属性的先后顺序
19     fieldsets = [
20         ("num",{"fields":['ggirlnum','gboynum']}),
21         ("base", {"fields": ['gname','gdate','isDelete']}),
22     ]#给属性分组
23    #fields和fieldsets两个属性不可以同时使用
24 admin.site.register(Grades,GradesAdmin)
25 
26 class StudentsAdim(admin.ModelAdmin):
27     def gender(self):#把布尔值显示为文字
28         if self.sgender:
29             return "男"
30         else:
31             return "女"
32     #设置页面列的名称
33     gender.short_description = "性别"
34 
35     list_display = ['pk','sname','sage',gender,'scontend','sgrade','isDelete']
36     list_per_page = 10
37     #执行动作的位置
38     actions_on_top = False
39     actions_on_bottom = True
40 admin.site.register(Students,StudentsAdim)

使用装饰器完成注册

 1 @admin.register(Students)
 2 class StudentsAdim(admin.ModelAdmin):
 3     def gender(self):#把布尔值显示为文字
 4         if self.sgender:
 5             return "男"
 6         else:
 7             return "女"
 8     #设置页面列的名称
 9     gender.short_description = "性别"
10 
11     list_display = ['pk','sname','sage',gender,'scontend','sgrade','isDelete']
12     list_per_page = 10
13     #执行动作的位置
14     actions_on_top = False
15     actions_on_bottom = True
16 #admin.site.register(Students,StudentsAdim)

2.视图的基本使用

定义视图在view.py中写

1 from django.http import HttpResponse
2 def index(request):
3     return HttpResponse("sunck si a good man")

配置url

修改project目录下的url.py文件

1 from django.contrib import admin
2 from django.urls import path,include
3 
4 urlpatterns = [
5     path('admin/', admin.site.urls),
6     path(r'',include('myApp.urls')),
7 
8 ]

 

在myApp应用目录下创建一个url.py文件

1 from django.conf.urls import url
2 from . import views
3 urlpatterns = [
4     url(r'^$',views.index)
5 ]

view.py

1 from django.http import HttpResponse
2 def index(request):
3     return HttpResponse("sunck si a good man")
4 def detail(request,num,num2):
5     return  HttpResponse("detail-%s-%s"%(num,num2))

url.py

1 from django.conf.urls import url
2 from . import views
3 urlpatterns = [
4     url(r'^$',views.index),#可以匹配http://127.0.0.1:8000/
5     url(r'^(\d+)/(\d+)/$',views.detail)#可以匹配http://127.0.0.1:8000/数字/数字/
6 ]

 

3.模板的使用

模板是HTML页面，可以根据视图中传递过来的数据进行填充

创建模板

        创建templates目录，在目录下创建对应项目的模板目录（project/templates/myApp）

配置模板路径

修改settings.py文件

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR,'templates')],
        'APP_DIRS': True,
       'OPTIONS': {

在templates/myApp下创建两个html模板即grades.html和students.html

 模板语法：

            {{输出值，可以是变量，也可以是对象，属性}}

            {%执行代码段%}

用 http://127.0.0.1:8000/grades打开写模板文件

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <title>班级信息</title>
 6 </head>
 7 <body>
 8    <h1>班级信息列表</h1>
 9    <u1>
10        <!--[python04,python05,python06]-->
11        {%for grade in grades%}
12        <li>
13               <a href="="#>{{grade.gname}}</a>
14        </li>
15        {%endfor%}
16    </u1>
17 </body>
18 </html>
