After quickstarting a project the json.py module contains some useful
default jsonifyers, for instance for User, Permission, etc. I often
find myself returning tg_errors in json for which a jsonifyer is
needed. This is what I currently use:
from formencode.api import Invalid
from turbojson.jsonify import jsonify
@jsonify.when( 'isinstance( obj, Invalid )' )
def jsonify_tg_errors( obj ):
result = { }
result['msg'] = obj.msg
result['value'] = obj.value
result['error_list'] = getattr( obj, 'error_list', None )
result['error_dict'] = getattr( obj, 'error_dict', None )
return result
It would be handy maybe for others too if this jsonifyer would be in
json.py just like User, Permission, etc by default.
Cheers,
Daniel
