django dumpdata空数组

本文介绍了django dumpdata空数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我对django并不陌生，我正在用它来建立一个在线游戏网站。游戏已经拥有自己的身份验证内容，因此我将其用作django的自定义身份验证模型。

I am fairly new to django and I am using it to make a website for an online game. The game already has it's own auth stuff so I am using that as a custom auth model for django.

我创建了一个名为帐户的新应用，将其放入其中并添加了模型。我添加了路由器并在设置中启用了它，一切正常，我可以从管理站点登录并进行操作。

I created a new app called 'account' to put this stuff in and added the models. I added the router and enabled it in the settings and everything works good, I can log in from the admin site and do stuff.

现在我也在尝试学习TDD，所以我需要将auth数据库转储到Fixture。 当我运行 ./ manage.py dumpdata帐户时，我得到了一个空数组。迄今为止没有任何错误或任何追溯，只是一个空数组。我尽了最大的努力来弄弄它，但似乎找不到问题所在。

Now I am also trying to learn TDD, so I need to dump the auth database to a fixture. When I run ./manage.py dumpdata account i get an empty array back. There aren't any errors or any trace back what so ever, just an empty array. I've fiddled with it the best I can but I can't seem to find what the issue is.

以下是一些相关设置。

DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'censored', 'USER': 'censored', 'PASSWORD': 'censored', 'HOST': 'localhost', 'PORT': '', }, 'auth_db': { 'ENGINE': 'mysql_pymysql', 'NAME': 'censored', 'USER': 'censored', 'PASSWORD': 'censored', 'HOST': '127.0.0.1', 'PORT': '3306' } }

路由器

class AccountRouter(object): """ A router to control all database operations on models in the account application. """ def db_for_read(self, model, **hints): """ Attempts to read account models go to auth_db. """ if model._meta.app_label == 'account': return 'auth_db' return None def db_for_write(self, model, **hints): """ Attempts to write account models go to auth_db. """ if model._meta.app_label == 'account': return 'auth_db' return None def allow_relation(self, obj1, obj2, **hints): """ Allow relations if a model in the account app is involved. """ if obj1._meta.app_label == 'account' or \ obj2._meta.app_label == 'account': return True return None def allow_syncdb(self, db, model): """ Make sure the account app only appears in the 'auth_db' database. """ if model._meta.app_label == 'account': return False return None

Django设置

DATABASE_ROUTERS = ['account.router.AccountRouter']

对于尝试什么我真的很茫然，感谢任何帮助或想法。

I am really at a loss for what to try, any help or ideas are appreciated.

推荐答案

我也有同样的问题，您需要指定正确的数据库。例如，给定您的代码：

I also had the same issue, you need to specify the correct database. For example, given your code:

$ ./manage.py dumpdata --database=auth_db account
