【问题描述】：

当我尝试添加表情符号时，我得到了这个错误，即使 CharField 得到同样的错误也没有锻炼。 models.py

class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments', on_delete=models.CASCADE)
content = models.TextField(max_length=500, blank=False)
author = models.ForeignKey(User, on_delete=models.CASCADE)
date_created = models.DateTimeField(default=timezone.now)

def __str__(self):
    return self.content

def get_absolute_url(self):
    return reverse('post-detail', kwargs={'pk': self.post.pk})  # returns a string to the post detail that uses the pk of the comment instance. post. pk to link to the correct detail page ie. /post/

def save(self, *args, **kwargs):
    super(Comment, self).save(*args, **kwargs)
    n = 4
    truncatewords = Truncator(self.content).words(n)
    notify.send(self.author, recipient=self.post.author, verb='commented "' + truncatewords + '" on your post!', action_object=self.post, description='comment', target=self)

【解决方案1】：

要允许表情符号字符，您需要将列排序规则设置为 utf8mb4_unicode_ci，这将允许所有字符，并且在 MySQL 连接中，您还需要将 charset 设置为 utf8mb4。
