You want to do this in a modelform, and then specify that model form
in your admin.py. Put the checks in the overall form clean method (as
it refers to more than one field). In your model allow blank/null.

This is from the top of my head, but you probably want to say
null=True (i am guessing you'll leave this field empty in some cases)
and blank=True on certain model field, then override models save()
method to check for some conditions under which you want or do not
want to allow the field to be empty.

I am not sure how you would rise validation error from save() though.

Model field validation for admin

[pixelcowboy]

Hello, I want to make a field optional (blank=True), only if another
text field's options match a certain value in the admin. Is there any
way to do this? Thanks!
