NoReverseMatch：对于'author_update'与参数'（）'和关键字arguments'{ 'pk'：39，'user_id'：< SimpleLazyObject：< User：fdf>>}未找到。尝试了1个模式：['author /（？P< user_id> \\d +）/（？P< pk> \\d +）$']
解决方案
尝试更改此行 return reverse（'author_update'，kwargs = pk'：self.pk，'user_id'：self.created_by}） to：
return reverse（'author_update'，args =（self.pk，self.created_by.pk））
或
return reverse（'author_update'，
kwargs = {'pk'：self.pk，'user_id' self.created_by.pk}）
I get this error

解决方案
Try to change this line return reverse('author_update', kwargs={'pk': self.pk, 'user_id': self.created_by}) to:
return reverse('author_update', args=(self.pk, self.created_by.pk))
or
return reverse('author_update',
kwargs={'pk': self.pk, 'user_id': self.created_by.pk})
