在django中与遗留数据库集成

标签： django django-models django-admin

models.py是从旧版数据库创建的。我创建了models.py并为应用admin.py创建了interface，并在installed app创建了应用名称，我有大约76个表（76 classes in models.py）。

admin.py：

#! /usr/bin/env python  
from django.contrib import admin  
from django.db import models  
from interface.models import Students,ApplyLeaves  
site.register(ApplyLeaves)  
site.register(Students)  
for m in get_models(db):  
       site.register(m)

在上述情况下，Student和ApplyLeaves类未在管理界面中注册。

我已将admin.py放在app目录以及项目目录中，仍未将app注册为管理

如果您想将所有模型注册到django admin，您应该（尽管您不必须）创建管理的实例。

这是因为，尽管django admin可以仅基于模式公开所有模型，但是它有很多花哨和小气来使模式表示有意义的真实解决方案。

那就是说，在你的情况下，你不应该将这个admin.py保留在项目级别，而只是在应用程序级别。 Students和ApplyLeaves在同一个db数据库中是否已传递给get_models？

您将要做的优雅解决方案如下：

project-folder/bare_tables.py 

from django.db.models import get_models
from django.contrib.admin import AdminSite, ModelAdmin

class BareTables(AdminSite):
    pass

new_admin = BareTables(name='bare_tables')

for el in get_models():
    new_admin.register(el,ModelAdmin)

在urls.py

中 
 from bare_tables import new_admin

 urlpatterns = patterns('',
     (r'^bare-tables/', include(new_admin.urls)),
     (r'^admin/', include(admin.site.urls)),

这样，当/admin中显示所有表格时，您可以继续在/bare-tables中构建有意义的界面。
