|
Allows a class to implement its adapting logic with a `js_args()` method on the class itself.
|
|
This just helps reduce the amount of code you have to write.
|
|
|
|
For example:
|
|
|
|
@adapter('wagtail.mywidget')
|
|
class MyWidget():
|
|
...
|
|
|
|
def js_args(self):
|
|
return [
|
|
self.foo,
|
|
]
|
|
|
|
Is equivalent to:
|
|
|
|
class MyWidget():
|
|
...
|
|
|
|
|
|
class MyWidgetAdapter(Adapter):
|
|
js_constructor = 'wagtail.mywidget'
|
|
|
|
def js_args(self, obj):
|
|
return [
|
|
self.foo,
|
|
]
|
|
"""
