比萨在Django的pdf生成CSS [英] CSS not rendered by Pisa's pdf generation in Django
本文介绍了比萨在Django的pdf生成CSS的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用比萨从HTML生成pdf文件:
def fetch_resources(uri,rel):
/ pre>
path = os.path.join(settings.MEDIA_ROOT,uri.replace(settings.MEDIA_URL,))
返回路径
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')
pdf = .pisaDocument(StringIO.StringIO(
html.encode(UTF-8)),结果,link_callback = fetch_resources)
result.close()
我的HTML具有指向外部CSS的链接,并且正确呈现,但是比萨不使用CSS(例如,字体大小,表格宽度,文本-align ...)。
<!DOCTYPE html>
< html lang =fr>
< head>
< link rel =stylesheethref =/ site_media / style / style.css/>
< / head>
< body>
....
我错过了什么?
谢谢
解决方案您可以尝试这个比萨和reportlab-pitfalls
我不得不添加这个def fetch_resources(uri,rel):
除此之外,我仍然将所有的CSS都放在模板中。还要确保您使用的是 xhtml2pdf ,而不是旧的ho.pisa。
I generate a pdf file from HTML using Pisa:
def fetch_resources(uri, rel): path = os.path.join(settings.MEDIA_ROOT, uri.replace(settings.MEDIA_URL, "")) return path 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') pdf = pisa.pisaDocument(StringIO.StringIO( html.encode("UTF-8")), result, link_callback=fetch_resources) result.close()
My HTML has a link to an external CSS and is rendered properly, but the CSS is not used by Pisa (eg. font size, table cell width, text-align...).
<!DOCTYPE html> <html lang="fr"> <head> <link rel="stylesheet" href="/site_media/style/style.css" /> </head> <body> ....
Did I miss something?
Thanks
解决方案You could try this 'Pisa-and-Reportlab-pitfalls' I had to add this
def fetch_resources(uri, rel):
On top of that I still carry all my css within the template. Also make sure you're using xhtml2pdf and not the old ho.pisa.
