Methods
IN
IN(
value
)
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__
__eq__(
value
)
Return a FilterNode instance representing the = comparison.
__ge__
__ge__(
value
)
Return a FilterNode instance representing the >= comparison.
__gt__
__gt__(
value
)
Return a FilterNode instance representing the > comparison.
__le__
__le__(
value
)
Return a FilterNode instance representing the <= comparison.
__lt__
__lt__(
value
)
Return a FilterNode instance representing the < comparison.
__ne__
__ne__(
value
)
Return a FilterNode instance representing the != comparison.
__neg__
__neg__()
Return a descending sort order on this Property.
For example:
Employee.query().order(-Employee.rank)
__pos__
__pos__()
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)
