Question

我正在尝试使用django-import-export实现一个简单的xls文件导入并保存到模型中。不幸的是，文档仅涵盖了管理集成。我被困在我的示例代码中：

class UploadFileForm(forms.Form):
    file = forms.FileField()


class ExportSpec(resources.ModelResource):
    class Meta:
        model = Specialty

view:
def ca_import(request):
    if request.method == 'POST' and 'import_test' in request.POST:
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            filehandle = request.FILES['file']
            dataset = ???
            result = ExportSpec().import_data(dataset, dry_run=False,
                                          raise_errors=True,
                                          user=request.user)

了解此模块的人是否可以帮助我完成此通用示例的代码？

或者是否有一个通用的例子在网上某个地方被剪断了，我没有用google找到它？

根据Alex的回答，我找到了一个可行的解决方案：

def ca_import(request):
    if request.method == 'POST' and 'import_test' in request.POST:
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            file = form.cleaned_data['file']
            data = bytes()
            for chunk in file.chunks():
                data += chunk
            dataset = XLS().create_dataset(data)
            result = ExportSpec().import_data(dataset, dry_run=False, raise_errors=True, user=request.user)

您应该使用Format.create_dataset()方法：

from import_export.formats.base_formats import XLS

def your_view():
    filehandle = form.cleaned_data['file']
    data = bytes()
        for chunk in import_file.chunks():
            data += chunk
    dataset = XLS().create_dataset(data)
    result = ExportSpec().import_data(...)
