Re: Preprocess data before showing it on Admin

Thanks for your time and your tips Marc!

I had tried earlie what you suggested but it didnt solved my problem because it only assigns initial values to new records and not to existents ones.

But i finally figured out a small change on code which does it well. I just replaced "self.fields['your_field'].initial" with "self.initial['text']".

Thanks again! Regards,

sure, you can do it on form __init__ method

something like

class YourForm(ModelForm):
   def __init__(self, *args, **kwargs):
       super(YourForm, self).__init__(*args, **kwargs)
       self.fields['your_field'].initial = your_postprocess_method()

also you should override the save form method in order to "reverse"
the postprocess and save the data in raw format.
