I've changed to
def show():
# called to show one entry and its linked comments based on
# the entry.id
# called by TOC in order to provide an entry.id
#id=request.vars.id
id = request.args[0]
## <--- changed line
entries=cynotedb(cynotedb.entry.id==id).select()
# to prevent showing a 'None' (null) entry
if not len(entries): redirect(URL(r=request,f='entries'))
# form to post new comments
comments=SQLFORM(cynotedb.comment,fields=['author','file','body'])
# give entry.id for comment output
comments.vars.entry_id = id;
# return the comment that is listed with the entry id
records=cynotedb(cynotedb.comment.entry_id==id)\
.select(orderby=cynotedb.comment.entry_id)
# show a flash when comment is posted
if comments.accepts(request.vars,session):
response.flash = "comment posted"
return dict(entry=entries[0],comments=comments,records=records)
It gives this error:
Traceback (most recent call last):
File "D:\web2py\gluon\restricted.py", line 98, in restricted
exec ccode in environment
File "D:/web2py/applications/cynote/controllers/cynote.py", line
131, in <module>
File "D:\web2py\gluon\globals.py", line 74, in <lambda>
self._caller = lambda f: f()
File "D:/web2py/applications/cynote/controllers/cynote.py", line 22,
in show
id = request.args[0]
IndexError: list index out of range
And "print request.vars.id, request.args" shows "1 []" which is why
there is an IndexError.
