Display Extra Field

• See django admin - add custom form fields that are not part of the model

  class MyModelAdmin(models.ModelAdmin):
        list_display = ('field1', 'field2', 'combined_fields')
        readonly_fields = ('combined_fields', )
  
        def combined_fields(self, obj):
                return '{} {}'.format(obj.field1, obj.field2)
  

  • combined_fields is a extra field and can use as defined field
