Xadmin组件的url设计

 

1.注册一个新的app，创建Xadmin.py

 

  from django.conf.urls import url

from django.shortcuts import HttpResponse, render

 

 

class ModelXadmin(object):

    def __init__(self, model, site):

        self.model = model

        self.site = site

 

    def list_view(self, request):

 

        data_list = self.model.objects.all()

        return render(request, 'list_view.html', {'data_list':data_list})

    def add_view(self, request):

        return HttpResponse('add_view')

    def change_view(self, request, num):

        return HttpResponse('change_view')

    def delete_view(self, request, num):

        return HttpResponse('delete_view')

 

    def get_urls_operate(self):

        temp = []

        temp.append(url(r'^$', self.list_view))

        temp.append(url(r'^add/$', self.add_view))

        temp.append(url(r'^(d+)/delete', self.delete_view))

        temp.append(url(r'^(d+)/change', self.change_view))

        return temp

 

    @property

    def urls_operate(self):

        return self.get_urls_operate(), None, None

 

 

class XadminSite(object):

    def __init__(self):

        self._registry = {}

 

    def get_urls(self):

        temp = []

        for model, admin_class_obj in self._registry.items():

            model_name = model._meta.model_name

            app_name = model._meta.app_label

            temp.append(url(r'^{0}/{1}/'.format(app_name, model_name), admin_class_obj.urls_operate))

        return temp

 

    @property

    def urls(self):

        return self.get_urls(), None, None

 

    def register(self, model, admin_class=None, **options):

        if not admin_class:

            admin_class = ModelXadmin

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

 

site = XadminSite()

 

2.在另外的app下创建Xadmin.py

 

from Xadmin.service.Xadmin import site

 

from app02.models import *

 

site.register(demo)

site.register(demo02)

site.register(demo03)

site.register(Food)

 

print('-registry', site._registry)

print('--'*20)

 

3.url.py

 

from Xadmin.service.Xadmin import site

urlpatterns = [

    url(r'^Xadmin/', site.urls),

]
