题
我的计划是让用户在上载Excel文件后,一旦上传,我将显示包含上传excel内容的可编辑表单,一旦用户确认输入正确,他/她命中了保存按钮,并保存这些项目。在某些型号。
为此,我写了此观点并形式:
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
看法:
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()
我需要从内存中阅读,但是 open_workbook
从文件中读取,而无需将此输入保存到某个地方,我该如何阅读?
解决方案
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})
什么时候 file_contents
提供可选的关键字, filename
关键字将不会使用。
愉快的编码。
