declaration_file¶

The descriptor for the file attribute on the model instance. Returns a FieldFile when accessed so you can do stuff like:

>>> from myapp.models import MyModel
>>> instance = MyModel.objects.get(pk=1)
>>> instance.file.size

Assigns a file object on assignment so you can do:

>>> with open('/path/to/hello.world', 'r') as f:
...     instance.file = File(f)

>>> from myapp.models import MyModel
>>> instance = MyModel.objects.get(pk=1)
>>> instance.file.size

Assigns a file object on assignment so you can do:

>>> with open('/path/to/hello.world', 'r') as f:
...     instance.file = File(f)

source_code_file¶

The descriptor for the file attribute on the model instance. Returns a FieldFile when accessed so you can do stuff like:

save(*args, **kwargs)[source]¶

Saves the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.
