I thing you can also get the paginate parameters from the original
http request stored by cherrypy.
I thing this is called
cherrypy.request.params
look the cherrypy doc to be sure.
Then extract the paginate parameters and do something like
for i, entry in enumerate(entries):
idx=i-(paginate_no-1)*paginate_limit
if 0<=idx and idx<=paginate_limit:
entry.viewed = 1
return dict(entries=entries)
Remi, I like your solution, but prefere to use use a callable this
way :
@expose(...)
@stats('entries', lambda x: x.viewed = 1)
@paginate('entries', ...)
with stats looking like :
def stats(var_name, callable):
def decorator(func):
def wrapper(*args, **kw):
output = func(*args, **kw)
if var_name not in output:
log.info(u"%s not in the result dict" % var_name)
else:
resultat = output[var_name]
for r in resultat:
callable(r)
return output
return wrapper
return decorator
