New submission from Dann Ke:
I'm using the json library to serialize objects out for web use.
Whenever I serialize a datetime or other included python library object (uuid
as another example), it fails with
TypeError: datetime.datetime(2014, 5, 20, 9, 37, 56, 133627) is not JSON
serializable
While this behaviour is well and good, what I am suggesting is that I would
like a way for this library to attempt to serialize an object when it
encounters an exception.
For instance, if it attempts to serialize a datetime and fails, I would like
the option of submitting a method as a parameter to the json.dumps() method
that the object is put into in an attempt to serialize it.
As a code example:
import datetime, json
json.dumps(dict(mydate=datetime.datetime.now()),
serialize=str)
That way, when it encounters a TypeError, it will set mydate to a string and
will be serialized out.
Right now, I have to use str() on a few different fields because they are not
standard types (str, int, bool, float, None, etc)
This isn't a priority and I'm open to criticisms. Would you accept a patch for
this if you are too busy to work on this feature?
Thank you for your time.
Dann
