1、stark組件開發

stark組件開發，仿django自帶得admin組件。

1、django的admin配置

from django.contrib import admin

# Register your models here.
from .models import *

class UserAdmin(admin.ModelAdmin):
    list_display = ["pk",‘name‘,‘age‘]
    list_filter = [‘name‘,‘age‘]

    # 定制action具體方法
 

    def func(self,request,queryset):
        queryset.update(age=44)

    func.short_description = "批量初始化操作"
    actions = [func]

admin.site.register(UserInfo,UserAdmin)
admin.site.register(Book)

makemigrations
migrate
createsuperuser （alex 1234qwer）

2、starkadmin註冊register

1. startapp stark

stark/service/stark.py (單例)

class ModelStark(object):
    """Book,Userinfo對象"""
    def __init__(self, model, site):
        self.model = model
        self.site = site


class StarkSite(object):
    """site單例對象的創建類"""
    def __init__(self):
        self._registry 
 
= {}

    def register(self,model, stark_class=None):
        if not stark_class:
            stark_class = ModelStark

        self._registry[model] = stark_class(model,self)


site = StarkSite()

2. settings中配置

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

class App01Config(AppConfig):
    name = ‘app01‘

    # 程序啟動時，掃描app下得指定文件（starkadmin.py）並執行
    def ready(self):
        autodiscover_modules(‘starkadmin‘)

3、創建文件starkadmin：仿admin文件

app01/starkadmin.py

4、url

2、生成url

1、2層url分發初級版本

from django.conf.urls import url
from django.shortcuts import HttpResponse


class ModelStark(object):
    """Book,Userinfo對象"""
    def __init__(self, model, site):
        self.model = model
        self.site = site


class StarkSite(object):
    """site單例對象的創建類"""
    def __init__(self):
        self._registry = {}

    def register(self,model, stark_class=None):
        if not stark_class:
            stark_class = ModelStark

        self._registry[model] = stark_class(model,self)

    def list_view(self,request):
        return HttpResponse(‘list_view‘)

    def add(self,request):
        return HttpResponse(‘add‘)

    def delete(self, request, id):
        return HttpResponse(‘delete‘)

    def change(self, request, id):
        return HttpResponse(‘change‘)

    def get_urls2(self):
        """構造 add/delete/change"""
        temp = []
        temp.append(url(r‘^$‘, self.list_view))
        temp.append(url(r‘^add/‘, self.add))
        temp.append(url(r‘^(\d+)/delete/‘, self.delete))
        temp.append(url(r‘^(\d+)/change/‘, self.change))

        return temp

    @property
    def urls2(self):
        return self.get_urls2(), None, None

    def get_urls(self):
        """構造urls：app01/book"""
        temp = []

        print(self._registry)
        for model, stark_class_obj in self._registry.items():
            model_name = model._meta.model_name
            app_label = model._meta.app_label

            # 分發增刪改查
            temp.append(url(r‘^%s/%s/‘ % (app_label, model_name), self.urls2))

        return temp

    @property
    def urls(self):
        return self.get_urls(), None, None

site = StarkSite()

2、如何保證不同的Model模型表對應不同的頁面展示

3、ModelStark

ModelStark()
    self.model:用戶訪問的模型表

4、二次分發優化版本

from django.conf.urls import url
from django.shortcuts import HttpResponse


class ModelStark(object):
    """Book,Userinfo對象"""
    def __init__(self, model, site):
        self.model = model
        self.site = site

    def list_view(self, request):
        print(self.model)   # <class ‘app01.models.Book‘>  用戶訪問的模型表
        return HttpResponse(‘list_view‘)

    def add(self, request):
        return HttpResponse(‘add‘)

    def delete(self, request, id):
        return HttpResponse(‘delete‘)

    def change(self, request, id):
        return HttpResponse(‘change‘)

    def get_urls2(self):
        """構造 add/delete/change"""
        temp = []
        temp.append(url(r‘^$‘, self.list_view))
        temp.append(url(r‘^add/‘, self.add))
        temp.append(url(r‘^(\d+)/delete/‘, self.delete))
        temp.append(url(r‘^(\d+)/change/‘, self.change))

        return temp

    @property
    def urls2(self):
        return self.get_urls2(), None, None

class StarkSite(object):
    """site單例對象的創建類"""
    def __init__(self):
        self._registry = {}

    def register(self,model, stark_class=None):
        if not stark_class:
            stark_class = ModelStark

        self._registry[model] = stark_class(model,self)

    def get_urls(self):
        """構造urls：app01/book  app01/Userinfo"""
        temp = []

        print(self._registry)
        for model, stark_class_obj in self._registry.items():
            model_name = model._meta.model_name
            app_label = model._meta.app_label

            print(model,‘---->‘,stark_class_obj)
            """
            <class ‘app01.models.UserInfo‘> ----> <app01.starkadmin.UserConfig object at 0x00000072DDB65198>
            <class ‘app01.models.Book‘> ----> <stark.service.stark.ModelStark object at 0x00000072DDB65240>
            """
            # 分發增刪改查
            temp.append(url(r‘^%s/%s/‘ % (app_label, model_name), stark_class_obj.urls2))
            """
            path(‘app01/userinfo/‘,UserConfig(Userinfo,site).urls2),
            path(‘app01/book/‘,ModelStark(Book,site).urls2),
            """
        return temp

    @property
    def urls(self):
        return self.get_urls(), None, None

site = StarkSite()

7 stark配置，生成2層 url
