Hi Massimo
I have a problem here. One of my functions work perfectly in Version
1.47 (2008-10-27 12:36:17) but failed in Version 1.56.2 (2009-02-08
21:49:34) with 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

if comments.accepts(request.vars,session):
File "D:\web2py\gluon\sqlhtml.py", line 422, in accepts
raise SyntaxError, 'user is tampering with form'
SyntaxError: user is tampering with form
A snipplet of the model is this:
cynotedb.define_table('entry',
SQLField('title'),
SQLField('file','upload'),
SQLField('filename'),
SQLField('keywords',length=256),
SQLField('notebook',cynotedb.notebook),
SQLField('datetime','datetime',default=now),
SQLField('description','text'))
#the comment table
#entry_id link to entry table
cynotedb.define_table('comment',
SQLField('author'),
SQLField('file','upload'),
SQLField('filename'),
SQLField('body', 'text'),
SQLField('datetime','datetime',default=now),
SQLField('entry_id',cynotedb.entry))
The code in question is this:
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
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','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)
The error seems to lie at
if comments.accepts(request.vars,session):
response.flash = "comment posted"
When I comment out these Version 1.56.2 (2009-02-08 21:49:34), the
function works but I am not able to add new comments into
cynotedb.comment table.
I think this error seems to be induced by a new version of web2py.
My reasons being:
1. When I run a older developmental version of my application (cynote)
in Version 1.47, it works nicely - Not in Version 1.56.2
2. When I copy and pasted the older version into my application in
web2py Version 1.56.2 (trying to rule out indentation and invisible
characters error), it failed.
3. When I copied the entire application directory into web2py Version
1.47, it works fine.
Hence, the only reason that I cannot rule out is the difference in
web2py versions.
Please advice.
Thanks
Maurice Ling
