我想覆盖管理器类，以便允许将内容数据从文本文件(此处为“/ one directory / myPrefix_ *”)加载到内容字段而不是数据库表中。
class Things(model.Models):
file = CharField(max_length = 25, primary key = True)
content = TextField()
objects = myManager("/one directory/", "myPrefix_")
如果可能的话，我将很高兴在管理站点中使用此类。
我的梦想可能吗？
我会通过将对象重命名为_objects，然后创建一个属性函数来加载数据来解决这个问题。类似下面的代码应该做你需要的......
class Things(model.Models):
file = CharField(max_length = 25, primary key = True)
content = TextField()
_objects = CharField(max_length = 50)
@property
def objects(self):
return load_content_from("/one directory/myPrefix_" + self._objects)
如果您想查看管理站点中文件的内容，那么您可能需要创建自己的字段类型(请参阅http://code.djangoproject.com/browser/django/trunk/django/db/models/领域)。
I would like to override the manager class in order to allow content data to be loaded from text files (here on of "/one directory/myPrefix_*") into content field instead of from a database table.
class Things(model.Models):
file = CharField(max_length = 25, primary key = True)
content = TextField()
objects = myManager("/one directory/", "myPrefix_")
I would appreciate to use this class in the admin site, if possible.
Is my wild dream possible?
I would solve this by renaming objects to _objects, and then creating a property function to load the data. Something like the code below should do what you need...
class Things(model.Models):
file = CharField(max_length = 25, primary key = True)
content = TextField()
_objects = CharField(max_length = 50)
@property
def objects(self):
return load_content_from("/one directory/myPrefix_" + self._objects)
If you want to see the content from the files in the admin site then you'll probably need to create your own field type (see http://code.djangoproject.com/browser/django/trunk/django/db/models/fields).
