[Answer]-Custom Number Field is not executing "to_python"?


Finally got the answer 🙂

Had to understand how the SQLite database system works!

The problem here is, when the Database which we are using, let it be any in that case. Firstly we shall format the data to be stored into it. Once the types are assigned to the database table fields, (I don’t know why) still it can save data of other format (May be bug in SQLite, table had Integer field but still stored 350 characters long string, command line displayed). Problem arises when retrieval is done, Database SW will look for Integer value from the field but gets some non-supported values. (Hence error).

May be my question now shifted to the one in brackets in fore mentioned paragraph ? Is it true (because it proved like that to me) or Is there other reasons ?
