day18 stark组件开发之动态生成url
思路：
项目目录
在两个app中创建表结构
app01/models.py
from django.db import models
# Create your models here.
class Depart(models.Model):
"""
部门表
"""
title = models.CharField(verbose_name='部门名称', max_length=32)
class UserInfo(models.Model):
"""
用户表
"""
name = models.CharField(verbose_name='姓名', max_length=32)
age = models.CharField(verbose_name='年龄', max_length=32)
email = models.CharField(verbose_name='邮箱', max_length=32)
depart = models.ForeignKey(verbose_name='部门', to='Depart',on_delete=models.CASCADE)
app02/models.py
from django.db import models
# Create your models here.
class Host(models.Model):
"""
主机表
"""
host = models.CharField(verbose_name='主机名', max_length=32)
ip = models.GenericIPAddressField(verbose_name='IP')
class Role(models.Model):
"""
角色
"""
title = models.CharField(verbose_name='角色名称', max_length=32)
设置路由
from django.contrib import admin
from django.urls import path, include
from django.conf.urls import url
from stark.service.v1 import site
urlpatterns = [
path('admin/', admin.site.urls),
url(r'^stark/', site.urls),
]
stark组件编写动态生成url代码

self._registry.append({'model_class': model_class, 'handler': handler_class(model_class)})
def get_urls(self):
patterns = []
for item in self._registry:
model_class = item['model_class']
handler = item['handler']
app_label, model_name = model_class._meta.app_label, model_class._meta.model_name
patterns.append(url(r'%s/%s/list/$' % (app_label, model_name,), handler.changelist_view))
patterns.append(url(r'%s/%s/add/$' % (app_label, model_name,), handler.add_view))
patterns.append(url(r'%s/%s/change/(\d+)/$' % (app_label, model_name,), handler.change_view))
patterns.append(url(r'%s/%s/del/(\d+)/$' % (app_label, model_name,), handler.change_view))
return patterns
@property
def urls(self):
return self.get_urls(), self.app_name, self.namespace
site = StarkSite()
在stark项目的apps.py文件加上下面的代码，ready函数的作用是让Django在启动时自动扫描每一个app下面的stark.py文件
from django.apps import AppConfig
from django.utils.module_loading import autodiscover_modules
class StarkConfig(AppConfig):
default_auto_field = 'django.db.models.BigAutoField'
name = 'stark'
def ready(self):
autodiscover_modules('stark')
不同的app编写调用自动生成url模块
