Question

我有一个名为xyz.com的域名运行带有数据库的django项目。我有另一个Django项目应该指向xyz.com/pray与不同的数据库。是否可以这样做？

Answer 1

是的，我会看两件事：

适用于您的某个应用程序的数据库路由器
每个应用的urls.py文件

项目/ urls.py：

urlpatterns = patterns('',
    ...
    url(r'^pray/', include('prayapp.urls')), # all of this apps ulrs start with /pray
    url(r'^', include('otherapp.urls')), # all of these urls start at the root /
    ...
)

和https://docs.djangoproject.com/en/1.3/topics/db/multi-db/#an-example：

数据库设置：

DATABASES = {
# for the rest of your project
'default': {
    'NAME': 'app_data',
    'ENGINE': 'django.db.backends.postgresql_psycopg2',
    'USER': 'postgres_user',
    'PASSWORD': 's3krit'
},
# for your prayapp
'other': {
    'NAME': 'user_data',
    'ENGINE': 'django.db.backends.mysql',
    'USER': 'mysql_user',
    'PASSWORD': 'priv4te'
}
}

自定义路由器：

class PrayAppRouter(object):
    """A router to control all database operations on models in
    the prayapp application"""

    def db_for_read(self, model, **hints):
        "Point all operations on prayapp models to 'other'"
        if model._meta.app_label == 'prayapp':
            return 'other'
        return None

    def db_for_write(self, model, **hints):
        "Point all operations on prayapp models to 'other'"
        if model._meta.app_label == 'prayapp':
            return 'other'
        return None

    def allow_relation(self, obj1, obj2, **hints):
        "Allow any relation if a model in prayapp is involved"
        if obj1._meta.app_label == 'prayapp' or obj2._meta.app_label == 'prayapp':
            return True
        return None

    def allow_syncdb(self, db, model):
        "Make sure the prayapp app only appears on the 'other' db"
        if db == 'other':
            return model._meta.app_label == 'prayapp'
        elif model._meta.app_label == 'prayapp':
            return False
        return None

将此添加到您的settings.py

DATABASE_ROUTERS = ['path.to.PrayAppRouter',]

我可以将2个不同的Django应用指向2个不同的网址吗？
