使用比萨将pdf写入磁盘 [英] Using Pisa to write a pdf to disk

问题描述

我让比萨在浏览器中以django格式生成.pdfs，但是如果我想自动将文件写入磁盘该怎么办？我想要做的是能够在指定的时间点生成.pdf版本文件并将其保存在上载目录中，因此没有浏览器交互。

I have pisa producing .pdfs in django in the browser fine, but what if I want to automatically write the file to disk? What I want to do is to be able to generate a .pdf version file at specified points in time and save it in a uploads directory, so there is no browser interaction. Is this possible?

推荐答案

是可以的。例如，使用 Greg Newman 作为启动器：

Yes it is possible. for example, using code from Greg Newman as a starter:

from django.template.loader import get_template
from django.template import Context
import ho.pisa as pisa
import cStringIO as StringIO
import cgi

def write_pdf(template_src, context_dict, filename):
    template = get_template(template_src)
    context = Context(context_dict)
    html  = template.render(context)
    result = open(filename, 'wb') # Changed from file to filename
    pdf = pisa.pisaDocument(StringIO.StringIO(
        html.encode("UTF-8")), result)
    result.close()

您只需要使用模板，字典中的数据和文件名来调用write_pdf。

You just need to call write_pdf with a template, data in a dict and a file name.
