Hi Sam,
I ran into this same problem. The easy way to fix it was to use the
decorator module to preserve method signature. If you look at some of
the builtin decorators with Pylons like @jsonify and @validate, this
is how they do it - check pylons/decorators/__init__.py.
Here is jsonify with decorator applied after function definition.
from decorator import decorator
def jsonify(func, *args, **kwargs):
"""Action decorator that formats output for JSON
Given a function that will return content, this decorator will
turn the result into JSON, with a content-type of 'text/
javascript'
and output it.
"""
pylons.response.headers['Content-Type'] = 'text/javascript'
data = func(*args, **kwargs)
if isinstance(data, list):
msg = "JSON responses with Array envelopes are susceptible to
" \
"cross-site data leak attacks, see " \
"http://pylonshq.com/warnings/JSONArray";
warnings.warn(msg, Warning, 2)
log.warning(msg)
log.debug("Returning JSON wrapped action output")
return simplejson.dumps(data)
jsonify = decorator(jsonify)
