Methods

IN

View source

Comparison operator for the IN comparison operator.

The Python IN operator cannot be overloaded in the way we want to, so we define a method. For example:

Employee.query(Employee.rank.IN([4, 5, 6]))

Note that the method is called ._IN() but may normally be invoked as .IN(); ._IN() is provided for the case you have a StructuredProperty with a model that has a Property named IN.

__eq__

View source

Return a FilterNode instance representing the = comparison.

__ge__

View source

Return a FilterNode instance representing the >= comparison.

__gt__

View source

Return a FilterNode instance representing the > comparison.

__le__

View source

Return a FilterNode instance representing the <= comparison.

__lt__

View source

Return a FilterNode instance representing the < comparison.

__ne__

View source

Return a FilterNode instance representing the != comparison.

__neg__

View source

Return a descending sort order on this Property.

For example:

Employee.query().order(-Employee.rank)

__pos__

View source

Returns an ascending sort order on this property.

Note that this is redundant but provided for consistency with __neg__. For example, the following two are equivalent:

Employee.query().order(+Employee.rank)
Employee.query().order(Employee.rank)
