Attributes Documentation

notes

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

software

Accessor to the related object on the forward side of a many-to-one or one-to-one (via ForwardOneToOneDescriptor subclass) relation.

In the example:

class Child(Model):
    parent = ForeignKey(Parent, related_name='children')

Child.parent is a ForwardManyToOneDescriptor instance.

software_id

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

user

Accessor to the related object on the forward side of a many-to-one or one-to-one (via ForwardOneToOneDescriptor subclass) relation.

In the example:

class Child(Model):
    parent = ForeignKey(Parent, related_name='children')

Child.parent is a ForwardManyToOneDescriptor instance.

user_id

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

work_flow_file

The descriptor for the file attribute on the model instance. Return a FieldFile when accessed so you can write code like:

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

Assign a file object on assignment so you can do:

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

work_flow_text

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

Methods Documentation

clean() → None

Enforce the integrity of the relationship to Software or User

Ensure that one and only one of Software or User is not null
