I believe I have a solution in the last commit:
44904e47f5b5eec89b06ec332bd3094ec76ec3dd
If should allow to do
db.mytable.myfield.readable = True
@action('index')
@action.uses(db)
def index():
db.mytable.myfield.readable = False
and makes db.mytable.myfield.readable thread safe while, every http
request, sees the default values defined at the top level.
I have tested the module I created to achieve this but I have not tested
its application to the Field class.
Also this is not necessarily final since it is a first version of the
threadsafevariable library.
If you can think of more ways to test it, it would be appreciated.
