Hi, I have a model with an integer field storing a duration in hours, while I want to present that to users in a form in days. (The choice of these different units is imposed by other factors not under my control.)
So, when saving a form, I need to convert a value in days to hours by multiplying by 24. I've done that with a clean_<fieldname>() method on the form, as described at https://docs.djangoproject.com/en/2.2/ref/forms/validation/. That works fine for when saving a new model. When editing an existing model however, I need to take the value from the model stored in hours, and convert that to days for display in the edit form. I've considered various places where I could do that conversion, for instance in the edit view, or the form __init__() method, or the model field's value_from_object() method, but none of those choices seem like the obvious choice, and I can't find a recommendation for how to do this either. What would you suggest? And is the recommended approach actually documented somewhere that I've missed?
