Having the problem with multiple object return

For my project i am doing a resume parser. When i upload one resume, it was able to extract those data. When i upload more resume i get this error, i understand it does matter with get() or filter().

I have tried changed my user details user_detail = UserDetails.objects.get(user=user) from get() to filter(), although it resolve the multiple object error, but it having another issue is my result extract nothing, no result show at all. It means it doesn’t extract any data from my resume although upload successful

def homepage(request):
    if request.method == 'POST':
        user = User.objects.get(id=1)
        file_form = UploadResumeModelForm(request.POST, request.FILES)
        files = request.FILES.getlist('resume')
        if file_form.is_valid():
            for file in files:
                    user = User.objects.get(id=1)

                    # saving the file
                    resume = Resume(user=user, resume=file)

                    # extracting resume entities
                    parser = resume_parser.ResumeParser(os.path.join(settings.MEDIA_ROOT, resume.resume.name))
                    data = parser.get_extracted_data()

                    # User Details
                    # resume.name          = data.get('name')
