Re: copying sqlite database file between projects
That solved the syncdb error, but I'm still getting the same error inside the shell when I am trying get to the data. Progress! Thanks again!

Re: copying sqlite database file between projects
Yup. That did it. The errors were a result of setttings.py pointing to the wrong database. Too much mucking about with too many things at the same time...

Re: cleaned_data not behaving how I expect it to. (newbie confusion)
Thanks for the "heads up". I actually was aware of this. When I'm trying to figure this kind of thing out, I start with the simplest problem and then add complications once I understand the fundamentals -- even if that means doing it the wrong way initially. Perhaps not the best approach... Thanks again! On 08/02/11 09:21, Tom Evans wrote: On Mon, Feb 7, 2011 at 11:54 PM, Ben Dembroski wrote: My apologies to the list.

Hi Tom,
Thanks for your reply. (You're right, my example was lousy).
I did in fact try what you suggested earlier on, and got the the
following error:
AttributeError at /people/add/
'ValidationError' object has no attribute 'message_dict'
I have this in the code:
from django.core.exceptions import ValidationError, NON_FIELD_ERRORS
and the code is currently so:
except ValidationError, e:
errormsg = e.message_dict[NON_FIELD_ERRORS]
form = EditPerson()
return render_to_response('personentry.html', { 'form' : form,
'errormsg': errormsg },context_instance=RequestContext(request))
Why are you trying to catch the ValidationError? The whole point is
that this is caught by the form's `clean()` method and then the
message appears in the error dictionary.

I knew someone was going to ask that :)
Mostly, it's a 'hacky' reason. In this occasion, the form is collecting
the date date in 'sections', Year, Month, Day. Only the Year is
required. The month and the day are optional. If the user leaves the
month and / or day fields blank, the view is inserting dummy values
into the database. (Don't ask me why, please).
At the moment, all the form is doing is checking to make sure each field
is an integer, and has the appropriate number of digits in each field.
However, it's still possible for a user to enter an invalid date -- Like
1956 - 02 - 31. The form is valid, but the date is not. Handling the
exception being raised by the model validation just seemed easier for
some reason.

Hmm, I think the docs are, if not wrong, misleading. From looking at
the code (1.2/trunk), ValidationError only has an attribute
message_dict if it is constructed with a dictionary (I let out an
audible 'ewww' as I read the code).
If it is constructed with a string or a list of strings, then it
should have an attribute messages, which is a simple list of strings.
There is also a method update_error_dict(). I think using this, you
can write some code which works in all cases:
from django.core.exceptions import ValidationError, NON_FIELD_ERRORS
try:
...
except ValidationError, e:
message_dict = e.update_error_dict({})
print message_dict[NON_FIELD_ERRORS]
Just while I'm on this class, the update_error_dict() method will
happily take None as an argument if it is constructed with a
dictionary (by design, it checks for it), but blows up if it is
constructed with a list or a string:
e=ValidationError({'foo': 'bar'})
e.update_error_dict(None)
{'foo': 'bar'}
e=ValidationError('foo bar')
e.update_error_dict(None)
Traceback (most recent call last):
File "", line 1, in
File "django/core/exceptions.py", line 85, in update_error_dict
error_dict[NON_FIELD_ERRORS] = self.messages
TypeError: 'NoneType' object does not support item assignment
This class is horrendous - however it is constructed, it should
present a consistent interface. It can't even present a consistent
method.
Dirty, Bad and Wrong.
Cheers
Tom
Thanks Tom.
Did the trick!
