akvo.rsr.models.result.indicator_period_label module

class akvo.rsr.models.result.indicator_period_label.IndicatorPeriodLabel(*args, **kwargs)[source]

Bases: Model

Model for adding a label on an indicator period.

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

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

periods

Accessor to the related objects manager on the reverse side of a many-to-one relation.

In the example:

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

Parent.children is a ReverseManyToOneDescriptor instance.

Most of the implementation is delegated to a dynamically defined manager class built by create_forward_many_to_many_manager() defined below.

project

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.
