Django和xlrd,从内存中读取

我的计划是让用户上传excel文件,一旦上传,我将显示包含上传的excel内容的可编辑表单,一旦用户确认输入正确,他/她点击保存按钮,这些项目保存在某个模型中。

为此,我写了这个观点和形式:

形式:

IMPORT_FILE_TYPES = ['.xls', ]

class XlsInputForm(forms.Form):
    input_excel = forms.FileField(required= True, label= u"Upload the Excel file to import to the system.")

    def clean_input_excel(self):
        input_excel = self.cleaned_data['input_excel']
        extension = os.path.splitext( input_excel.name )[1]
        if not (extension in IMPORT_FILE_TYPES):
            raise forms.ValidationError( u'%s is not a valid excel file. Please make sure your input file is an excel file (Excel 2007 is NOT supported.' % extension )
        else:
            return input_excel

查看:

def import_excel_view(request):
    if request.method == 'POST':
        form = XlsInputForm(request.POST, request.FILES)
        if form.is_valid():
            input_excel = request.FILES['input_excel']
            # I need to open this input_excel with input_excel.open_workbook()
            return render_to_response('import_excel.html', {'rows': rows})
    else:
        form = XlsInputForm()

    return render_to_response('import_excel.html', {'form': form})

正如您在# I need to open this input_excel with input_excel.open_workbook()看到的那样,我需要从内存中读取,但open_workbook从文件中读取,而不将此输入保存到某处,我该如何阅读?

答案 0 :(得分:55)

if form.is_valid():
    input_excel = request.FILES['input_excel']
    book = xlrd.open_workbook(file_contents=input_excel.read())

    # your work with workbook 'book'

    return render_to_response('import_excel.html', {'rows': rows})

提供file_contents个可选关键字后,系统不会使用filename个关键字。

快乐编码。
