Stark组件

stark组件就是仿django admin做的一款后台管理工具

分隔为5大顺序实现

URL设计

from django.db import models

# Create your models here.

from django.db import models
class Author(models.Model):
    nid = models.AutoField(primary_key=True)
    name=models.CharField( max_length=32)
    age=models.IntegerField()

    # 与AuthorDetail建立一对一的关系
    authorDetail=models.OneToOneField(to="AuthorDetail",on_delete=models.CASCADE)

    def __str__(self):
        return self.name

class AuthorDetail(models.Model):

    nid = models.AutoField(primary_key=True)
    birthday=models.DateField()
    telephone=models.BigIntegerField()
    addr=models.CharField( max_length=64)

    def __str__(self):
        return self.addr



class Publish(models.Model):
    nid = models.AutoField(primary_key=True)
    name=models.CharField( max_length=32)
    city=models.CharField( max_length=32)
    email=models.EmailField()
    def __str__(self):
        return self.name


class Book(models.Model):

    nid = models.AutoField(primary_key=True)
    title = models.CharField( max_length=32)
    publishDate=models.DateField()
    price=models.DecimalField(max_digits=5,decimal_places=2)

    # 与Publish建立一对多的关系,外键字段建立在多的一方
    publish=models.ForeignKey(to="Publish",to_field="nid",on_delete=models.CASCADE)
    # 与Author表建立多对多的关系,ManyToManyField可以建在两个模型中的任意一个，自动创建第三张表
    authors=models.ManyToManyField(to='Author',)
    def __str__(self):
        return self.title

from django.contrib import admin

from app01.models import *
# Register your models here.

#注册表名------------------
admin.site.register(Book)
admin.site.register(Author)

from django.conf.urls import url
from django.contrib import admin
from django.shortcuts import render,HttpResponse,redirect

#匹配视图部分---------------------------------
def whq(request):
    return HttpResponse('whq')

def add(request):
    return HttpResponse('增加')

def delete(request):
    return HttpResponse('删除')

def change(request):
    return HttpResponse('修改')
def list(request):
    return HttpResponse('查看')

#url部分----------------------------------------------
def get_urls():
    temp=[]
    temp.append(url(r'add/', add),)
    temp.append(url(r'delete/', delete),)
    temp.append(url(r'change/', change),)
    temp.append(url(r'list/', list),)
    return temp

#
def get_urls2():
    '''
    model:admin.py里注册的表名
    model_config：admin.py里注册表的配置名

    :return:
    '''
    temp=[]
    for model,model_config in admin.site._registry.items():
        print(model,model_config)
        #获取APP名称-----------------------
        app_label = model._meta.app_label
        #获取表名------------------------------
        mode_name = model._meta.model_name
        # temp.append(url(r'^%s/%s'%(app_label,mode_name),(get_urls(),None,None) ))
       #添加生成rul---------------------------
        temp.append(url(r'^%s/%s' % (app_label, mode_name), (get_urls(), None, None)))
    return temp


urlpatterns = [
    url(r'^admin/', admin.site.urls),
    #输入浏览器后匹配的url--------------------
    url(r'^whq/', (get_urls2(),None,None)),
]
#     url(r'^whq/', ([
#             url(r'^test01/', test01),
#             url(r'^test02/', test02),
#             url(r'^test03/', test03),
#             url(r'^test04/', test04),
#
#                    ],None,None)),
# ]

 该功能实现了三级url基本思路 http://127.0.0.1:8092/whq/app01/book/list 查看 http://127.0.0.1:8092/whq/app01/book/add 添加 以此类推 

start注册

 settings文件：

注册app INSTALLED_APPS = [ 'whqstark.apps.WhqstarkConfig', ] 

apps.py:
from django.apps import AppConfig
from django.utils.module_loading import autodiscover_modules

class WhqstarkConfig(AppConfig):
    name = 'whqstark':app名称
    def ready(self):
        autodiscover_modules('stark')#自动扫描stark.py文件
