We found the solution and it's completely unrelated to SWIG.
Problem emanated from the ODBC driver for the Vertica DB we were using which behaved unpredictably when using a long variable to bind the SQL result to.
Tomer and Inbal | 1 | 0 | 0 | I have code in python that integrates c++ code using swig.
The c++ class has a field with the long value 1393685280 which is converted to python.
The problem is that when calling the getter of this field from python I get the int value -2901282016 instead.
How can I fix it?

Since you say you're using a form, you shouldn't be accessing data via request.POST, but by form.cleaned_data, which will do the work to translate that into the actual object. | 1 | 0 | 0 | One of my form fields is a Foreign Key drop down.

However, instead of getting (using request.POST.get('value', False)) the value I am getting a number (which seems to be arbitrary).
How can I get the selected value?
