Admin initial code

# PRESENTING CODE

from myapp.models import Author

admin.site.register(Author)


# USING DECORATORS

from django.contrib import admin
from .models import Author


@admin.register(Author)
class AuthorAdmin(admin.ModelAdmin):
    pass

Lets customize

# PRESENTING CODE


@admin.register(Author)
class AuthorAdmin(admin.ModelAdmin):
    list_display = ["name", "birth_date"] 
    # to show all => list_display = BookAdmin._meta.get_all_field_names()
    

### what else? ###

@admin.register(Author)
class AuthorAdmin(admin.ModelAdmin):
    list_display = ["name", "birth_date", "ratings_count"]  # ratings_count is a model function
    

    @admin.display(empty_value="N/A") 
    def ratings_count(self, obj):
        return self.google_ratings + self.kindle_ratings

But Elad, What about Item view?

# PRESENTING CODE

# MODEL

class Author(models.Model):
    name = models.CharField(max_length=100)
    title = models.CharField(max_length=3)
    birth_date = models.DateField(blank=True, null=True)
    
# ADMIN -> admin.py code


class AuthorAdmin(admin.ModelAdmin):
    fields = ["name", "title"]

## OR ##

class AuthorAdmin(admin.ModelAdmin):
    exclude = ["birth_date"]

List View
