django 用reportlab将页面转成pdf

Question

问题遇到的现象和发生背景

django 用reportlab 把当前页面转成pdf可以下载的那种
现在网上找到的都是一个some_view()只有一个hello world。难道要一个个p.drawString()吗？教人教一半我也是服了

问题相关代码，请勿粘贴截图

import io
from app01 import models
from django import forms
from django.http import FileResponse
from django.shortcuts import redirect, render
from django.utils.safestring import mark_safe
from reportlab.pdfgen import canvas

def some_view(request):
    # Create a file-like buffer to receive PDF data.
    buffer = io.BytesIO()

    # Create the PDF object, using the buffer as its "file."
    p = canvas.Canvas(buffer)

    # Draw things on the PDF. Here's where the PDF generation happens.
    # See the ReportLab documentation for the full list of functionality.
    p.drawString(100, 100, "Hello world.")

    # Close the PDF object cleanly, and we're done.
    p.showPage()
    p.save()

    # FileResponse sets the Content-Disposition header so that browsers
    # present the option to save the file.
    buffer.seek(0)
    return FileResponse(buffer, as_attachment=True, filename="hello.pdf")


def user_list(res):
    page_str = ""
    size = 10
    d = 0
    page = int(res.GET.get("page", 1))
    if page == 1:
        start_page = 0
        end_page = size
    else:
        end_page = page * size
        start_page = end_page - size
    total_data = models.UserInfo.objects.all().count()
    data = models.UserInfo.objects.all()[start_page:end_page]
    title = [field.verbose_name for field in models.UserInfo._meta.fields]
    for i in range(1, total_data + 1, 10):
        d += 1
        if page == d:
            page_str += f"""
">page={d}">{d}
"""
        else:
            page_str += f"""
page={d}">{d}
"""
    page_str = mark_safe(page_str)
    return render(res, "user_list.html", {"data": data, "title": title, "page_str": page_str})
