Thanks for that clarification. This works but it doesn't seem to be
robust.
If I have the data, this works great:
form.vars=request.vars
form.vars.meta_description=request.vars.meta_description.file.read()
db.domain.insert(**dict (form.vars))
However, if there's nothing there (nothing supplied via curl) it fails
silently. I don't get a ticket, the program doesn't crash but the
record is not added. I've tried testing for success using if and try/
except but I can't get it to trigger anything.
form.vars=request.vars
form.vars.meta_description=request.vars.meta_description.file.read()
if db.domain.insert(**dict (form.vars)) :
response.flash="inserted"
else:
response.flash="failed"
Neither works.
If I have to test for the existence of each possible field, I can.
But that's a lot more labor-intensive and error-prone. Every time
you add or modify a field, you need to make sure it has a test. So as
long as I'm the only one using it I'll probably do things on the
sending end - make an empty file and upload @blank
Or maybe I'm missing something?
Thanks very much for the help!
