admin.py:

class productadmin(admin.modeladmin):     list_display = ('name', 'creation_date', 'category', 'value', 'featured',)     read_only_fields = ('creation_date',)  admin.site.register(product, productadmin)

class productimageinline(admin.stackedinline):     model = productimage   class galleryadmin(admin.modeladmin):     inlines = [productimageinline]
