私はDjangoのアプリに取り組んでいます

取得するために defaultlist を使用しました: Key: -value -value -value Key2: -value -value value

しかし、出力に何もなく、ホームページを pdf にダウンロードしたいのですが、次のエラーが表示されます。

"/views.download_my_pdf の AttributeError 'str' オブジェクトに属性 'read' がありません"

どこで間違ったのですか？ご協力ありがとうございました

Django の views.py

from django.shortcuts import render
from django.core.files.storage import FileSystemStorage
import pandas as pd
from django.http import HttpResponse
from wsgiref.util import FileWrapper

def home(request):

    if request.method == 'POST':
        uploaded_file = request.FILES['document']
        uploaded_file2 = request.FILES['document2']

        if uploaded_file.name.endswith('.xls'):
            savefile = FileSystemStorage()
            name = savefile.save(uploaded_file.name, uploaded_file)
            name2 = savefile.save(uploaded_file2.name, uploaded_file2)

            d = os.getcwd()
            file_directory = d+'\\media\\'+name
            file_directory2 = d+'\\media\\'+name2

            results,output_df =results1(file_directory,file_directory2)
            return render(request,"results.html", {"results":results,"output_df":output_df,})

    return render(request, "index.html")

def readfile(uploaded_file):
    data = pd.read_excel(uploaded_file, index_col=None)
    return data


def results1(file1,file2):

    results_list = defaultdict(list)
    names_loc = file2
    listing_file = pd.read_excel(file1, index_col=None)

                 
                  for x in date_index:
                                          
                    if time>2h:
                        results_list["List of samples better"].append(sample_id)

                   
                    if len(u_index) > 1:

                        results_list["List of Samples "].append(sample_id)

       
                    output_df = output_df.append(row_to_add, ignore_index=True)
                else:

                    results_list["List of Samples not in the listing file"].append(sample_name[0])
            except:
                print('The template name isnt good: {}'.format(sample_id))

    return results_list, output_df.to_html()


def download_pdf(request):
    filename = 'faults.pdf'
    content = FileWrapper(filename)
    response = HttpResponse(content, content_type='application/pdf')
    response['Content-Length'] = os.path.getsize(filename)
    response['Content-Disposition'] = 'attachment; filename=%s' % 'faults.pdf'

    return response

.html

<!DOCTYPE html>
<html lang="en">
<head>

    <meta charset="UTF-8">
    <title> Dashboard Result</title>

</head>
<body style="margin-top: 30px; padding: 100px">

<a class="btn btn-primary" href="{% url 'download_pdf' %}" role="button">Download pdf</a>

{% for key, value in results1.items %}
    <tr>
        <td>{{ key }} </td>
        <td>{{ value }} </td>
    </tr>
{% endfor %}
</body>
</html>

django での私のアプリの urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home),
    path('views.download_my_pdf', views.download_pdf, name="download_pdf"),

]
