type 'exceptions.NameError' global name is not defined

[chienr]

Hi,

I'm new to web.py and have been struggling with this problem for the
past day. I hope someone can point me to where the problem is. I have
a for loop in a template like this:

$for line in lines:
$csv = line.rstrip().split(",")

But it's generating this error:

<type 'exceptions.NameError'> at /home
global name 'csv' is not defined

What does it mean?

Thanks,
Robert

It should be:

$for line in lines:
$ csv = line.rstrip().split(",")

(notice the space before csv.)

That worked! Thanks.

Now I have a new but similar problem.

$for line in linex:

$ csv = line.rstrip().split(",")

$ ltime = time.localtime(csv[2])

yields this error:

global name 'time' is not defined

I think you are referring to the python's built-in time module, if so you have to define the time in template globals first.

#in your code
import time

web.template.Template.globals['time'] = time

You're right, I am referring to the time module. And defining it in
globals works, thanks, but is this typical practice in web.py
applications? I saw some note about the upcoming 0.3 release moving
away from globals, so am I using templates in an unconventional way?
What's the correct way to do this?

In 0.3, the correct way to use globals is this:

globals = {'time': time}
render = web.template.render('templates', globals=globals)

See http://webpy.org/docs/0.3/templetor for more details.

You do not have variable defined within the function or at the global level.

The web.py templates are a a bit sensitive to space.

You need to add a space after the $

     $ csv = line.rstrip().split(",")
