How to restrict save function in Django admin

[Akshay Mukadam]

Hi,
I have developed application that loads CSV file, if the input received while parsing the CSV file in Django admin is wrong, it throws a stacktrace, to avoid stacktrace I have handled the exception and I am able to show the error message using the Message framework in django.
But the problem is that when I save the data it shows the error that CSV data is incorrect, but it also show save message, how could I override this.???
Thank You

Maybe you could show the code to clearly see what you are doing?

in admin.py

class MyModelAdmin(admin.ModelAdmin):

    def has_change_permission(self, request, obj=None):

        return False

Hi,

Would it work to validate the CSV in the form? Maybe start processing it, but if there's an error, raise a forms.ValidationError?
