I'd appreciate some help with the following problem, under Django 1.4
When running with the models, forms and view as described below, the data
from the form is *not* saved into the model.
However, when using the test code (shown at the end) in a shell
environment, the data *is* saved as expected.
How can I tell why the form data is not saved in the view? It appears to
"fail silently" (i.e. no errors reported) - but adding print statements
into the code reveal that the correct data is available just before the
.save() function. Is there a preferred approach for debugging this type of
situation?
Thanks
Derek
