Hi group, I have encountered a problem when I try to call a controller
which should return a JSON array of values from database. However in abou 1
of 5 cases this call stucks in "loading" phase (chrome animation in tab)
and no response is received. Data is in database, every other controller is
working fine, cpu utilization is pretty low so is the memory and there are
only about 10000 rows in DB. Could you please give me some hints?
Thanks, Jan
PS. The controller looks like this:
def dberrorsselect():
"""Performs sql query to get the errors in the form of list of dicts
such as {field_name:value}. This is then transformed to json dict for
transfer."""
if session.tb_id:
max_id=tb(tb.errors.test_id==session.tb_id).select(tb.errors.id.max()).first()[tb.errors.id.max()]
if max_id != None:
selector_id=int(max_id)-5
else:
selector_id=0
rows=tb((tb.errors.test_id==session.tb_id)&(tb.errors.id >
selector_id)).select(tb.errors.ts, tb.errors.msg_short, tb.errors.msg_long)
output=rows
else:
output=[]
return dict(output=output)
