1.配置站点(admin后台配置)
暂不配置2.创建模板目录/项目模板目录
在与myAPP同级的project目录下创建templates文件夹,在templates下面创建myApp文件夹myApp文件夹里面可以写自己的html代码,如students.html,grades.html
代码如下
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>班级信息</title>
</head>
<body>
<h1>班级信息列表</h1>
<ul>
<!--p/-->
{%for grade in grades%}
<li>
<a href="{{grade.id}}">{{grade.gname}}</a>
</li>
{%endfor%}
</ul>
</body>
</html><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>学生信息</title>
</head>
<body>
<h1>学生信息列表</h1>
<ul>
{% for student in students%}
<li>
{{student.sname}}--{{student.scontend}}
</li>
{%endfor%}
</ul>
</body>
</html>3.在settings.py中创建模板路径
主要在 TEMPLATES中
主要查看刚开始的 BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR,'templates')], #后来添加的,参考刚开始的代码
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]4.创建视图文件
在和templates以及project同级别的myApp文件夹,里面的view.py文件中创建视图函数from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
#视图对web请求进行回应
#视图就是python的一个函数,在本函数中定义
def index(request):
return HttpResponse("sunck is a good man ")
def detail(request,num,num2):
return HttpResponse('detail--%s--%s'%(num,num2))
def detail2(request,num):
return HttpResponse('%s-----------'%num)
from .models import Grades
def grades(request):
#去模型理取数据
gradesList =Grades.objects.all()
#将数据传递给模板,模板渲染页面,将渲染好的页面返回给浏览器
return render(request,'myApp/grades.html',{'grades':gradesList})
from .models import Students
def students(request):
studentsList = Students.objects.all()
return render(request,'myApp/students.html',{'students':studentsList})
def gradesStudents(request,num):
grade =Grades.objects.get(pk=num)
studentslist = grade.students_set.all()
return render(request, 'myApp/students.html', {'students': studentslist})
这里的各类函数都是通过project/view.py中的
urlpatterns = [
url('admin/', admin.site.urls),
url('^',include('myApp.urls')),
# url('^(\d+)/$',include('myApp.urls'))
]
来到第一个(层)myApp中的urls.py(和project齐名的)里面的
from django.conf.urls import url
from . import views
urlpatterns = [
url('^$',views.index),# ^$表示什么也没有,空白
url('^(\d+)$',views.detail2),
url('^(\d+)/(\d+)$',views.detail),
url('^grades/$',views.grades),
url('^students/$',views.students),
url('^grades/(\d+)$',views.gradesStudents),
]
5.在project下修改urls.py
from django.contrib import admin
from django.urls import path,include
from django.conf.urls import url
urlpatterns = [
url('admin/', admin.site.urls),
url('^',include('myApp.urls')),#这是后来添加的,表示任何链接都会导入到myApp.urls中
# url('^(\d+)/$',include('myApp.urls'))
]
6.在项目目录下创建urls.py(就是第一层myAPP.py下面的ursl.py)
from django.conf.urls import url
from . import views
urlpatterns = [
url('^$',views.index),# ^$表示什么也没有,空白
url('^(\d+)$',views.detail2),
url('^(\d+)/(\d+)$',views.detail),
url('^grades/$',views.grades),
url('^students/$',views.students),
url('^grades/(\d+)$',views.gradesStudents),
]
自此,运行项目,首页出现sunck is a good man
