Question

当我从Django将数据存储到MySQL时，出现错误：

Django Version: 1.7.7
Exception Type: Warning
Exception Value:    
Invalid utf8 character string: '800363'
Exception Location: /home/virtualenv/examenv/lib/python3.4/site-packages/MySQLdb/cursors.py in _warning_check, line 127
Python Executable:  /home/virtualenv/examenv/bin/python3
Python Version: 3.4.4

模型

class Test(models.Model):
    """
    The model of the test
    """

    # The name of the test
    name = models.CharField(max_length=500)
    # The description of test
    description = models.TextField(blank=True)
    # The test
    test = models.BinaryField(blank=True)
    # The author of the test
    author = models.ForeignKey(settings.AUTH_USER_MODEL)
    # The category of the test
    category = models.ForeignKey(Category)
    # date and time of create test
    date_and_time = models.DateTimeField(default=timezone.now())
    # How many users complete this test.
    rating = models.IntegerField(default=0)
    # Public or not public test
    is_public = models.BooleanField(default=True)

    def __str__(self):
        return self.name

我已经用utf-8格式创建了数据库如何解决此错误？

如果没有堆栈跟踪或产生错误的行，这是一个盲目猜测。但是，我确实在模型中看到了BinaryField。我想你正在使用Python MySql Connector。

我通过将二进制数据编码为十六进制字节串来解决了同样的错误。我实际上不希望这解决任何问题，二进制是二进制的，但这就是我使用它的方式：

import binascii
bin_data = some_function()  
repr(bin_data)
>>> b"R\x89\x9e\x86\xc6" # or something like that
test = Test()
# ...
hex_bin_data = binascii.hexlify(bin_data)
test.test = hex_bin_data
test.save()

hex_bin_data输出也是bytes。这是让我烦恼的事情。是什么让Python区分bin_data和hex_bin_data？应该有相同的字节没有？
