python之将应用程序切换到 Unicode

我的 model.py 看起来像:

import csv 
 
with open("organizationTest.txt","rU") as f: 
        reader = csv.reader(f) 
        for row in reader: 
            _, created = Company.objects.get_or_create( 
                Name=row[0], 
                Site=row[1], 
                ) 

“名称”和“站点”都在模型中描述!

每当我尝试运行我的服务器时，我都会得到

django.db.utils.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.

我怎样才能将我的应用程序切换到所说的 Unicode 字符串，或者是否有任何其他方法可以解决这个问题，我很想知道!

我很乐意回答任何问题!提前致谢!

编辑:这是完整的错误:

请您参考如下方法:

您似乎从不寻常的编解码器中获取字符。
csv文件的来源应该能告诉你他们用的是什么。
但是，您可以像这样从一种编解码器切换到另一种编解码器:

import csv 
 
with open("organizationTest.txt","rU") as f: 
        reader = csv.reader(f) 
        for row in reader: 
            _, created = Company.objects.get_or_create( 
                Name=row[0].decode('latin-1').encode('utf8'), 
                Site=row[1].decode('latin-1').encode('utf8'), 
                ) 

我建议您尝试一下。如果它仍然不起作用，请联系 csv 文件的创建者。
