我一直在关注这个tutorial,它帮助我使用xhtml2pdf在Django中生成了pdf文件。现在,我想要的是将生成的文件保存到磁盘上,而不必提示用户下载文件。

下面是我用来在utils.py文件和views.py文件中生成pdf文件的代码。

#utils.py file

from io import BytesIO
from django.http import HttpResponse
from django.template.loader import get_template
from xhtml2pdf import pisa

def render_to_pdf(template_src, context_dict={}):

    template = get_template(template_src)
    html  = template.render(context_dict)
    result = BytesIO()
    pdf = pisa.pisaDocument(BytesIO(html.encode("ISO-8859-1")), result)
    if not pdf.err:
        return HttpResponse(result.getvalue(), content_type='application/pdf')
    return None 

#views.py snippet of code

html = template.render(context)
pdf = render_to_pdf('tdn.html', context)
if pdf: 
    response = HttpResponse(pdf, content_type='application/pdf')
    filename = "TDN_%s.pdf" %("12341231")
    content = "inline; filename='%s'" %(filename)
    download = request.GET.get("download")
    if download:
        content = "attachment; filename='%s'" %(filename)
        response['Content-Disposition'] = content
    TDN.objects.filter(id=tdn_no).update(printed=1)
    return response

return HttpResponse("Not found")

任何有关如何将生成的pdf写入磁盘的指针将不胜感激

答案 0 :(得分:2)

尝试过吗?

with open('mypdf.pdf', 'wb+') as output:
    pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("UTF-8")), output)

如果要将其保存到ImageField,请在Django中使用ContentFile
