arya 项目01 （主要学习reverse方法，逆向解析url）
一、项目结构(只列出使用的文件)- learnmodelform    项目目录- app01    第一个appmodel.py    数据库文件arya.py    引用插件- arya    第二个appapps.py    加载自动搜索模块，django启动时自动搜索该我文件配置的模块- service    arya逻辑文件目录v1.py    逻辑代码文件，主要用来配置url，table表单展示数据，数据库操作等- learnmodelform settings.py  配置文件urls.py    路由文件- templates    模板文件model.py代码:from django.db import models# Create your models here.class Role(models.Model):caption = models.CharField(max_length=32)def __str__(self):return self.captionclass UserType(models.Model):title = models.CharField(max_length=32)def __str__(self):return self.titleclass UserInfo(models.Model):name = models.CharField(max_length=32)pwd = models.CharField(max_length=32)email = models.CharField(max_length=32)ut = models.ForeignKey(to="UserType", blank=True,null=True)roles = models.ManyToManyField(to="Role",blank=True)def __str__(self):return self.namearya.py代码:from arya.service import v1from . import models"""{models.UserInfo: AryaConfig(models.UserInfo,site),models.UserType: AryaConfig(models.UserType,site),}"""class UserInfoConfig(v1.AryaConfig):list_display = ['name', 'pwd', 'id', 'email']v1.site.register(models.UserInfo,UserInfoConfig)class UserTypeConfig(v1.AryaConfig):list_display = ['id', 'title']v1.site.register(models.UserType, UserTypeConfig)class RoleConfig(v1.AryaConfig):list_display = ['id', 'caption']v1.site.register(models.Role,RoleConfig)  apps.py代码(在arya应用中)from django.apps import AppConfigclass AryaConfig(AppConfig):name = 'arya'def ready(self):from django.utils.module_loading import autodiscover_modulesautodiscover_modules('arya')v1.py代码:from django.shortcuts import HttpResponse,render,redirectfrom django.utils.safestring import mark_safefrom django.urls import reverseclass AryaConfig(object):list_display = []def get_list_display(self):result = []result.extend(self.list_display)# 如果有编辑权限   #reslut=['name', 'pwd', 'id', 'email']result.append(AryaConfig.row_edit)# 如果有删除权限result.append(AryaConfig.row_del)result.insert(0, AryaConfig.row_checkbox)return resultdef row_del(self,row):# return row.name + row.email+str(row.id)# 生成删除URL# app01_userinfo_deleteapp = self.model_class._meta.app_label  #app名md = self.model_class._meta.model_namename = "arya:%s_%s_delete" %(app,md,)  #

views.py代码:
from django.shortcuts import render,redirect# Create your views here.
from django.forms import ModelForm
from . import modelsclass TestModelForm(ModelForm):class Meta:# model = models.UserInfomodel = models.UserTypefields = "__all__"def test(request):if request.method == "GET":obj = TestModelForm()return render(request,'test.html', {'obj':obj})else:obj = TestModelForm(data=request.POST)if obj.is_valid():obj.save()return redirect('/arya/app01/usertype/')return render(request,'test.html', {'obj':obj})def edit(request,nid):# user_obj = models.UserInfo.objects.filter(id=nid).first()user_obj = models.UserType.objects.filter(id=nid).first()if request.method == 'GET':obj = TestModelForm(instance=user_obj)return render(request,'edit.html',{'obj':obj})else:obj = TestModelForm(instance=user_obj,data=request.POST)if obj.is_valid():obj.save()return redirect('/arya/app01/usertype/')return render(request, 'edit.html', {'obj':obj})urls.pyfrom django.conf.urls import url,include
