Re: Suddenly I keep getting this error: invalid literal for int() with base 10: ''

Finally - FIXED!

After a some experimenting with the command line I found out that I can not access the foreign key field if there is no actual record.

So this throws the error as well:

>>> doc = main_documents.objects.create(doc_name="test", doc_description="description")
>>> doc.created_by

But after assigning a value, created_by is available:

>>> from accounts.models import UserAccount
>>> user = UserAccount.objects.get(pk=1)
>>> doc.created_by = user
>>> doc.created_by
<UserAccount: myemail@invalid.com>


So finally I changed my code to this:

(maybe there is some more elegant way, but currently the main thing is that it works now :-)

def doc_details(request, doc_id=None):

    isNewRecord = False

    if doc_id is not None:
        document = main_documents.objects.get(pk = doc_id)
    else:
        document = None
        isNewRecord = True

    if request.method == 'POST': # If the form has been submitted...
        form = DocumentForm(request.POST, instance=document) # A form bound to the POST data
        if form.is_valid():  # All validation rules pass
            document = form.save(commit=False)
            if isNewRecord or document.created_by is None:
                document.created_by = request.user
            document.save()
