我正在尝试遵循文档:https://docs.djangoproject.com/en/1.6/howto/legacy-databases/
首先,我将数据库添加到 settings.py,然后输入
python manage.py inspectdb
这是输出。很抱歉这么长;希望您只需要看大局。
我的问题是
1) 不知道怎么往数据库里放东西(用文本编辑器打开数据库时就是随机字符)
2) 如果我运行 python manage.py sqlcustom [app name] 没有任何输出
3) 很可能由于上述两个原因,导入的数据库在 Django 中显示为空。当我在 shell 中键入 Bonds.objects.all() 时,它返回一个空列表,而实际上应该有很多(我已经确认)。
# This is an auto-generated Django model module.
# You'll have to do the following manually to clean this up:
# * Rearrange models' order
# * Make sure each model has one field with primary_key=True
# * Remove `managed = False` lines if you wish to allow Django to create and delete the table
# Feel free to rename the models, but don't rename db_table values or field names.
#
# Also note: You'll have to insert the output of 'django-admin.py sqlcustom [appname]'
# into your database.

最佳答案
您是否遵循了其余的指示?您需要将 inspectdb
的输出添加到您的某个应用程序中的 models.py
文件,然后将该应用程序添加到您的 INSTALLED_APPS
。
尝试以下操作:
1) 创建应用
如果您没有要将 inspectdb
的输出放入其中的应用程序,只需运行 python manage.py startapp legacy
。这将创建一个名为 legacy
的应用程序,您可以通过它同步现有的数据库。
2) 将 inspectdb 输出添加到您应用的模型文件
在您选择的应用程序的 models.py
文件中,粘贴 inspectdb
命令的输出。最简单的方法可能是运行 python manage.py inspectdb > models.py
。这将在包含 manage.py
和您的应用程序目录的同一目录中创建一个名为 models.py
的文件。将该文件的输出复制到您应用的 models.py
文件中,即 legacy/models.py
。
3) 将您的应用添加到 INSTALLED_APPS
在您的 settings.py
中,将您的应用添加到 INSTALLED_APPS
。在此示例中,您希望将 'legacy',
添加到 INSTALLED_APPS
。
4) 运行syncdb
运行 python manage.py syncdb
以确保包含所有必需的表。看起来您已经有了基于上面粘贴的输出的那些,但再次运行它不会有什么坏处。
