I just upgraded to django 1.0 and started getting this error. I was
already using newforms and am quite surprised and dumbfounded by the
errror. Generally this error would be caused by a missing comma in a
tuple, but that appears to not be my case.
I added some print statements (to django/forms/fields.py) and even
over-wrote the variable in question to try and isolate the problem but
have had no success.
Below is a snip of the code in question, with my added debugging
statements. Note that even when I override "v" with a tuple containing
two string, I still get the error.
That almost makes me think something is broken with my python install,
however when I execute a similar statement from the python shell, it
works fine, and when I run the server with a different installation of
python I still get the error.
Below the code snip is the output I get in my terminal when the below
code runs. At the bottom of this post is a complete trace back of the
error.
I'm sure now that I am over looking something very obvious, and would
be very appreciate to any one who can point it out to me.
Thanks
