#1 Created at ... [Delete] [Delete and Lock User]

value = field.default() if callable(field.default) else field.default

#2 Created at ... [Delete] [Delete and Lock User]

当成if else语句来看

#3 Created at ... [Delete] [Delete and Lock User]

就是可以理解成这样？

if callable(field.default) :
    value = field.default()
else:
    value = field.default
