'How allow to fit read_only field for new record in TabularInline class in Django
I want to have a field readonly when record already saved but if admin adds a new record field must to be editable.
How I can achieve it?
Solution 1:[1]
You can use ModelAdmin's get_readonly_fields method for this purpose. When the object is created, the obj is set to None. By overriding the method, you can change the read_only fields if obj is present or not.
def get_readonly_fields(self, obj):
if obj:
return ['field_1', 'field_2']
else: # When object is created
return [] # no editable field
