How to display a boolean property in the django admin

Question

As we all know, displaying a method return value as boolean in the Django admin is easily done by setting the boolean attribute:

class MyMo         


        

Answer 1

You need to create a shadowing function to the property in the model. What I mean is that you will need to recreate a function in the ModelAdmin class with the same name as the property defined in the main Model.

Example:

# Model
class Product(models.Model):

    @property  # you can omit this decorator if you will access this property as a method of the model instance
    def in_stock(self):
        # boolean check return
        return self.quantity > 0

...

# Django-modeladmin
class ProductAdmin(admin.ModelAdmin):
    list_display = ('in_stock', ...)
    def in_stock(self, instance):
        return instance.in_stock

    in_stock.boolean = True
