# Create your models here.

    course = models.ManyToManyField(Course)

    def __unicode__(self):
        return '%s %s' % (self.isbn, self.title)

class BookAdmin(admin.ModelAdmin):
    list_display = ['isbn', 'title', 'authors', 'publisher', 'edition']

class ListingAdmin(admin.ModelAdmin):

admin.site.register(Book, BookAdmin)
