有没有办法用django模板中的pisa生成包含非ascii符号的pdf？
[英]Is there a way to generate pdf containing non-ascii symbols with pisa from django template?
问题描述
I'm trying to generate a pdf from template using this snippet:
我正在尝试使用以下代码段从模板生成 pdf：
def write_pdf(template_src, context_dict):
template = get_template(template_src)
context = Context(context_dict)
html = template.render(context)
result = StringIO.StringIO()
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("UTF-8")), result)
if not pdf.err:
return http.HttpResponse(result.getvalue(), mimetype='application/pdf')
except Exception('PDF error')
All non-latin symbols are not showing correctly, the template and view are saved using utf-8 encoding.所有非拉丁符号都没有正确显示，模板和视图使用 utf-8 编码保存。
I've tried saving view as ANSI and then to user unicode(html,"UTF-8"), but it throws TypeError.我试过将视图保存为 ANSI，然后保存给用户 unicode(html,"UTF-8")，但它抛出 TypeError。
Also I thought that maybe it's because the default fonts somehow do not support utf-8 so according to pisa documentation I tried to set fontface in template body in style section.我还认为可能是因为默认字体不支持 utf-8，所以根据 pisa 文档，我尝试在样式部分的模板正文中设置字体。
That still gave no results.那仍然没有结果。
Does any one have some ideas how to solve this issue?有没有人有一些想法如何解决这个问题？

Try replacing尝试更换
pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("UTF-8")), result)
with和
pdf = pisa.pisaDocument(StringIO.StringIO(html), result, encoding='UTF-8')
Or checkout this answer to html to pdf for a Django site?或者在 Django 网站上查看 html 到 pdf 的这个答案？

You need to modify your django template.您需要修改 django 模板。 Add a new font face in the stylesheet that will link to a font file with characters used in your document.在样式表中添加一个新字体，该字体将链接到包含文档中使用的字符的字体文件。 And that font file must be accessible from your server (under Ubuntu you can find files with fonts in /usr/share/fonts/truetype/ directory).并且该字体文件必须可以从您的服务器访问（在 Ubuntu 下，您可以在 /usr/share/fonts/truetype/ 目录中找到带有字体的文件）。 For example:例如：
@font-face {
font-family: DejaMono;
src: url(font/DejaVuSansMono.ttf);
}
Then if you have next HTML code:然后，如果您有下一个 HTML 代码：
<div>Some non-latin characters</div>
you can display that text in DejaMono font with this CSS rule:您可以使用以下 CSS 规则以 DejaMono 字体显示该文本：
div { font-family: DejaMono; }
This works for me when I generate PDF documents with cyrillic characters.当我生成带有西里尔字符的 PDF 文档时，这对我有用。

I faced the same problem with cyrillic characters.我在使用西里尔字符时遇到了同样的问题。
The solution contained two steps: 1. Point out the font file in your HTML file该解决方案包含两个步骤： 1. 指出 HTML 文件中的字体文件
<style type="text/css">
@font-face {
font-family: Arial; src: url("files/arial.ttf");
}
body {
font-family: Arial;
}
</style>
2. Give "pisa" root path (so that it find font file by relative path) in my case it was something like this 2.在我的例子中给出“pisa”根路径（以便它通过相对路径找到字体文件）它是这样的
pdf = pisa.pisaDocument(html, result, path=PATH_TO_DJANGO_PROJECT)
because fonts were placed at PATH_TO_DJANGO_PROJECT/files/arial.ttf因为字体被放置在 PATH_TO_DJANGO_PROJECT/files/arial.ttf

如果您正在调用 createPDF 而不是 pisaDocument 方法，您可以使用
pisa.CreatePDF(html.encode('UTF-8'), response, link_callback=fetch_resources, encoding='UTF-8')

I am using xhtml2pdf version 0.2.4 I faced the same issue and I was able to resolve using this encoding:我使用的是 xhtml2pdf 版本 0.2.4 我遇到了同样的问题，我能够使用以下编码解决：
def render_to_pdf(template_src, context_dict={}):
template = get_template(template_src)
html = template.render(context_dict)
result = BytesIO()
# PDF
pdf = pisa.pisaDocument(BytesIO(html.encode("utf-8")), result)
if not pdf.err:
return HttpResponse(result.getvalue(), content_type='application/pdf')
return None
Then in my views, I have defined like:然后在我看来，我定义如下：
def download_pdf(request, pk):
item = get_object_or_404(object, id=pk)
if item:
context ={
'item': item
}
template_name = 'template.html'
pdf = render_to_pdf(template_name, context)
return HttpResponse(pdf, content_type='application/pdf')
else:
messages.info(request, 'Item not found')
return redirect('home')
