我正在测试一些选项。我使用django-storages和S3上传了一个文件,它运行正常。但是,当我尝试使用下面的代码读取文件时,我收到以下错误:
'FieldFile'对象没有属性'startswith'
为什么吗
即使default_storage.exists(self.filepath)也会出错。
csv_file = default_storage.open(self.filepath, 'r')
new_object = CSVImport(csvfile=csv_file.read(),
model=Contact,
modelspy=".",
mappings="1=first_name,2=mobile,3=email,4=last_name,5=43,6=16")
new_object.run()

I have tried:
csv_file.read() gives same error.
Full Error details:
答案 0 :(得分:1)
错误是由:
引发的csv_file = default_storage.open(self.filepath, 'r')
表示self.filepath
的类型为FieldFile
。所以鉴于它的名字,我希望该对象是一个已经打开的文件。所以你应该尝试:
new_object = CSVImport(csvfile=self.filepath.read(), ... )
但我可能错了,self.filepath
可能是一个包含您要打开的文件路径的文件...鉴于您的代码示例很难说,我只能猜测。
答案 1 :(得分:0)
您正在将FieldFile
对象传递给default_storage.open()
,但它希望文件名为字符串。为其指定用于保存文件的名称,而不是FieldFile
对象。
