/ admin / ...中的UnicodeEncodeError - Django admin

时间：2016-07-24 21:19:04

标签： python django encoding django-admin

我在Django-admin面临编码问题。我有一个模型，它代表一个语言测验，包括内联到Quiz模型的问题和答案（都是模型）。

我创建了一个简单的csv导入。在Quiz模型中，有一个文件字段。当管理员创建新的Quiz时，他们会上传一个csv文件，该文件调用解析csv的信号并为此测验创建问题和答案。

英语没有问题，但是我试图导入法语测验，这会引起错误。

Exception Value:    
'ascii' codec can't encode character u'\ufeff' in position 0: ordinal not in range(128)

导入信号非常简单：

def parse_csv(csv):
    questions = []

for line in csv:

    line = line.strip('\r\n').strip('\n')
    d = {}
    items = line.split(';;')
    def parse_csv(csv):
        questions = []
        i=0
        for line in csv:
            i+=1
            print i
            line = line.strip('\r\n').strip('\n')
            d = {}
            items = line.split(';;')
            question = items[0]
            d['question'] = question
            for item in (x.strip() for x in items[1:]):
                if '|' in item:
                    d['answer'] = item
                else:
                    if 'choices' in d.keys():
                        d['choices'].append(item)
                    else:
                        d['choices'] = [item]
            if 'answer' not in d.keys():
                continue
            questions.append(d)

        return questions


    @receiver(post_save,sender=LanguageQuiz)
    def quiz_import_csv(sender,instance,created,**kwargs):
        if created:
            if instance.import_csv:

                questions =  parse_csv(instance.import_csv.readlines())

                for q in questions:
                    question = Question(text=q['question'])
                    question.save()
                    for ch in q['choices']:
                        choice = Choice(text=ch,correct=False)
                        choice.save()
                        question.choices.add(choice)
                    answer = Choice(text=q['answer'].strip('|'),correct=True)
                    answer.save()
                    question.choices.add(answer)
                    question.save()
                    instance.questions.add(question)

            instance.save()

你知道我该怎么做吗？

答案 0 :(得分：0)

好吧，我不知道你收到错误的地方。请在收到错误的地方张贴一行。

解析国际文本时，这是一个非常常见的错误。它是通过以下两种方法之一解决的：

使用UTF8进行编码

try:
    print (myThing)
except UnicodeEncodeError:
    print (myThing).encode('UTF8')

将文件作为字符串

读取

您还可以尝试以下代码courtesy of David Crook：

dataPath = "somepath.csv" # or other type of file
fil = open(dataPath)
txt = fil.readlines()
txt = ''.join(txt)
works = pd.read_csv(StringIO(txt), index_col = 0)
doesntWork = pd.read_csv(dataPath, index_col = 0)

答案 1 :(得分：0)

我也有同样的问题。 当我上传图片时，我看到了这个问题。 我意识到图像名称必须是英文，所以我将图像名称（其中一个是波斯语）更改为一些随机的英文名称。 为了解决这个问题，为图片字段创建验证器，将图片名称更改为随机英文名称或在上传前更改图片名称。

答案 2 :(得分：-3)

以下字母在法语中很常见：'é'，'è'，'ç'，'à'并且可能会破坏您的代码。

  

你知道我该怎么做吗？

为它复制问题写一个测试。一旦你编写它，你就可以更快地进行实验（使用内存文件）;在测试CSV中的所有单元格中添加有问题的字符;确保问题不再发生等等。

并修复它，可能是使用unicode(...)。例如：

text=unicode(q['question'])
