Write not fully displayed Django field

Question

I need to write a Django custom field where the stored value is not fully displayed. For example if the stored value is "079684" I need it to be displayed as "---84". Is it possible to do so ? If yes how should I implement my custom field ?

I'm not sure this is something to do at the *model* level. Typically the "presentation" of data is handled at the form, view, and/or template level. — Willem Van Onsem, Nov 01 '18 at 11:06

I have solved this by overriding from_db_value() of the custom field method.

It's an option, but I would say you should consider what can be achieved in a simple way. Using normal CharField and than slicing the value in template would be in my opinion more simple than going with custom field. – Uroš Trstenjak Nov 01 '18 at 14:31

You could store your value as a string in your model and than use slice in template to show only last two character.

{{ value|slice:"-2:" }}
