Update all .py source files by $ pyupgrade --py3-only $(git ls-files | grep ".py$") to modernize the code according to Python 3 syntaxes. Also add the pyupgrade hook to pre-commit to avoid merging additional Python 2 syntaxes. Change-Id: Iad18362b251f8ca947976e6150a1ed17ee4c5327

"""A Model With Default Views of Various Types
|
|
|
|
A model with default views has several predefined views,
|
|
each associated with a given type. This is often used for
|
|
when a submodel should have an attached view, but the view
|
|
differs depending on the serialization format
|
|
|
|
Parameters are as the superclass, except for any
|
|
parameters ending in '_view': these parameters
|
|
get stored as default views.
|
|
|
|
The default 'default views' are
|
|
|
|
text
|
|
:class:`oslo_reports.views.text.generic.KeyValueView`

|
xml
|
|
