Oh look, it's exactly the same error you started with. Congratulations,
you've made exactly no progress. As I asked you yesterday:
And what result does form.getvalue return?
What is its type? Is it a list, a tuple, a dict, a bytes object,
a float, a str object, something else?
Have you worked that out yet? If you can't work it out, you can guess,
and then test your guess:
page = form.getvalue('page')
if isinstance(page, list):
raise TypeError('guessed it was a list, it is a list')
If your guess is wrong, try another guess. Keep going until you work out
what type page is.
If you can't write to a data file, you can write to the error log:
page = form.getvalue('page')
raise TypeError('type of page is %r' % type(page))
Keep going until you find out what type of data the variable 'page' is
holding. Now read the error message again:
unsupported operand type(s) for %: 'bytes' and 'str'
Do you understand what that error means? Here is a hint: start a Python
interactive session, and try things for yourself:
steve@runes:~$ python3.3
Python 3.3.0rc3 (default, Sep 27 2012, 18:31:58)
[GCC 4.4.5] on linux
Type help, copyright, credits or license for more information.
py
py 'string%s' % 'string'
'stringstring'
py
py b'bytes%s' % b'bytes'
Traceback (most recent call last):
File stdin, line 1, in module
TypeError: unsupported operand type(s) for %: 'bytes' and 'bytes'
Do you see a pattern yet? What do you think will happen if you run this?
b'bytes%s' % 'string'
Try it and see for yourself.
Now look at the error message you are getting. Is it the same error
message? Do you think that perhaps it has the same cause? How do you
think you might solve this problem?
Hint: if you have a data item that is type A, and you need it to be type
B, you need to convert from A to B.

You tell us. You want to be a programmer, *you* need to do the
programming, and not just keep asking others to solve every single bug.
You have been given all the clues to solve this problem. Start by
checking what the type of 'page' is, then decide what it ought to be.
Hint: you can use
print(type(page), file=open('path/to/some/file', 'w'))
to see the type of the variable 'page' without displaying it on your
website.
all that is stores is the location of a file
path = '/home/nikos/public_html/'
page = form.getvalue('page')
And what result does form.getvalue return?
What is its type? Is it a list, a tuple, a dict, a bytes object, a float,
a str object, something else? DON'T GUESS, and don't assume, find out for
sure, by inspecting the result.
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )
So chnage it to what?
What do you think you need to change it to? Pick one:
1) bytes
2) an integer
3) a string
4) a list of floats
5) something else

Then pick a different location, one where you have permission to write

Honestly Nikos, I'm not trying to be rude, but if you cannot think of
this on your own after all this time we've been helping you, perhaps
programming is not the right vocation for you. Perhaps you need to
consider a change of career.
If you do decide to stay as a web developer, you need to start thinking:
* What is this error message telling me? (Permission denied)
* How can I fix that? (I need permission to read the file. Maybe try a
different file?)
Also many times when i try to view the error_log by
tail -F /usr/local/apache/logs/error_log
i get realtime scrolling of other joomla webistes pho errors and i have
hard time trackign my own webistes erros.
is ther a work around for that?
That's an apache logging issue, not Python, and I don't know enough about
apache to do more than guess that there probably is a solution but I have
no idea what it is.

Very nice idea, than k you steven. Less work withiut scrilling like hell liek
tail -F did.
this is what i have now:
# Exception Identification
def formatExceptionInfo(maxTBlevel=5):
cla, exc, trbk = sys.exc_info()
excName = cla.__name__
try:
excArgs = exc.__dict__[args]
except KeyError:
excArgs = no args
excTb = traceback.format_tb(trbk, maxTBlevel)
return (excName, excArgs, excTb)
try:
#find the needed counter for the page URL
if os.path.exists( path + page ) or os.path.exists( cgi_path + page ):
cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )
data = cur.fetchone() #URL is unique, so should only be one
except:
print( formatExceptionInfo() )
i see no error on what it used ot be isnteait comain at the follwing line which
is:
if not data:
#first time for page; primary key is automatic, hit is
defaulted
cur.execute('''INSERT INTO counters (url) VALUES
(%s)''', page )
cID = cur.lastrowid#get the primary key value
of the new record
else:
#found the page, save primary key and use it to issue
hit UPDATE
cID = data[0]
cur.execute('''UPDATE counters SET hits = hits + 1
WHERE ID = %s''', cID )
i jst dont follow. What ishsi proposed supposed to give us the error in the
query bit now it tells difefrent things.
shoudl i remove the function since it want any helopfull?

Use chmod and chown to change permissions and owners (i.e. groups). As a last resort (for testing purposes only!) you can set the directory world writable, but then *anyone* with access to that host can write/delete/destroy the contents of that directory. This is obviously very insecure and not a good idea. But if you are only trying to get a quick error message then it might work for you.

Let's look at the error in your log file:
[Wed Aug 28 13:08:27 2013] [error] [client 108.162.231.120] print(
repr(e) ) [Wed Aug 28 13:08:27 2013] [error] [client 108.162.231.120]
NameError: name 'e' is not defined
Did you bother to read the error before asking for help?
Variable 'e' is not defined. Perhaps you should define it?
Yes indeed , that was a a syntax error by me:
try:
#find the needed counter for the page URL
if os.path.exists( path + page ) or os.path.exists( cgi_path + page ):
cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )
data = cur.fetchone()#URL is unique, so should only be one
except Exception as e:
con.rollback()#something failed, rollback the entire transaction
print( repr(e) )
outputs:

So, in this line:

the variable 'page' needs conversion to what?
all that is stores is the location of a file
path = '/home/nikos/public_html/'
page = form.getvalue('page')
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )
So chnage it to what?

and data, therefore, comes the need to convert between them.
So, in this line:
cur.execute('''SELECT ID FROM counters WHERE url = %s''', page )
the variable 'page' needs conversion to what?
all that is stores is the location of a file
path = '/home/nikos/public_html/'
page = form.getvalue('page')
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )
So chnage it to what?

What is now proved was at first only imagined!
The error occurs in file
/usr/local/bin/python/lib/python3.3/site-packages/pymysql/cursors.py,
line 108, in execute
query = query % escaped_args
You can check the actual values and data types using:
print repr(query)
print type(query)
print repr(escaped_args)
print type(escaped_args)
Always useful is a proper exception handling using try:/except:

You tell us. You want to be a programmer, *you* need to do the
programming, and not just keep asking others to solve every single bug.
You have been given all the clues to solve this problem. Start by
checking what the type of 'page' is, then decide what it ought to be.
Hint: you can use
print(type(page), file=open('path/to/some/file', 'w'))
to see the type of the variable 'page' without displaying it on your
website.
all that is stores is the location of a file
path = '/home/nikos/public_html/'
page = form.getvalue('page')
And what result does form.getvalue return?
What is its type? Is it a list, a tuple, a dict, a bytes object, a float,
a str object, something else? DON'T GUESS, and don't assume, find out for
sure, by inspecting the result.
if not page and os.path.exists( file ):
# it is an html template
page = file.replace( path, '' )
So chnage it to what?
What do you think you need to change it to? Pick one:
1) bytes
2) an integer
3) a string
4) a list of floats
5) something else
