Set the value of foreign key from some different object , bigInteger

[shafihuzaib]

1. My model has a field 'department_id', which is set value as per the current authenticated user's department, hence cannot be allowed to set from views. So how to do that? I mean;
   • It is not available in view (as the department is implicit in such a context)
   • But the value for the said field is set automatically.

Please let me know if I should override some methods to get this done, in case it is not available yet.

1. Furthermore, the said field is bigInteger. Please let me know how to specify that.
