|Overview||Overview of Jinja2 filters, chaining filters and attributes.|
|default||If the value is undefined it will return the passed default value, otherwise the value of the variable.|
|map||Applies a filter on a sequence of objects or looks up an attribute. This is useful when dealing with lists of objects but you are really only interested in a certain value of it.
Alternatively you can let it invoke a filter by passing the name of the filter and the arguments afterwards.
|selectattr||Filters a sequence of objects by applying a test to the specified attribute of each object, and only selecting the objects with the test succeeding.
If no test is specified, the attribute’s value will be evaluated as a boolean.
