How to show all fields of model in admin page?

If you want to include all but the ManyToManyField field names, and have them in the same order as in the models.py file, you can use:

list_display = [field.name for field in Book._meta.fields if field.name != "id"]

As you can see, I also excluded the id.

If you find yourself doing this a lot, you could create a subclass of ModelAdmin:

class CustomModelAdmin(admin.ModelAdmin):
    
    def __init__(self, model, admin_site):
        self.list_display = [field.name for field in model._meta.fields if field.name != "id"]
        super(CustomModelAdmin, self).__init__(model, admin_site)

and then just inherit from that:

class BookAdmin(CustomModelAdmin):
    pass

or you can do it as a mixin:

class CustomModelAdminMixin(object):

    def __init__(self, model, admin_site):
        self.list_display = [field.name for field in model._meta.fields if field.name != "id"]
        super(CustomModelAdminMixin, self).__init__(model, admin_site)

class TradeAdmin(CustomModelAdminMixin, admin.ModelAdmin):
    pass

The mixin is useful if you want to inherit from something other than admin.ModelAdmin.

If you want to include all fields without typing all fieldnames, you can use

list_display = BookAdmin._meta.get_all_field_names()

The drawback is, the fields are in sorted order.

Edit:

This method has been deprecated in Django 1.10 See Migrating from old API for reference. Following should work instead for Django >= 1.9 for most cases -

list_display = [field.name for field in Book._meta.get_fields()]

By default, the admin layout only shows what is returned from the object's unicode function. To display something else you need to create a custom admin form in app_dir/admin.py.

See here: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display

You need to add an admin form, and setting the list_display field.

In your specific example (admin.py):

class BookAdmin(admin.ModelAdmin):
    list_display = ('title', 'author', 'price')
admin.site.register(Book, BookAdmin)
