有没有办法从django模板中使用pisa生成包含非ascii符号的pdf?
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')
所有非拉丁符号均未正确显示,模板和视图使用 utf-8 编码保存。
我尝试将视图保存为 ANSI,然后保存为用户 unicode(html,"UTF-8"),但它会抛出 TypeError。
我还想也许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主体中设置字体。
那仍然没有结果。
有人知道如何解决这个问题吗?
I'm trying to generate a pdf from template using this snippet:
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.
I've tried saving view as ANSI and then to user unicode(html,"UTF-8"), but it throws 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.
That still gave no results.
Does any one have some ideas how to solve this issue?

您需要修改您的 django 模板。在样式表中添加新字体,该字体将链接到包含文档中使用的字符的字体文件。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)。例如:
然后,如果您有下一个 HTML 代码:
您可以使用以下 CSS 规则以 DejaMono 字体显示该文本:
当我生成带有西里尔字符的 PDF 文档时,这对我有用。
You need to modify your django template. Add a new font face in the stylesheet that will link to a font file with characters used in your document. And that font file must be accessible from your server (under Ubuntu you can find files with fonts in /usr/share/fonts/truetype/ directory). For example:
Then if you have next HTML code:
you can display that text in DejaMono font with this CSS rule:
This works for me when I generate PDF documents with cyrillic characters.
我在使用西里尔字母时也遇到了同样的问题。
该解决方案包含两个步骤:
1. 指出 HTML 文件中的字体文件
2. 给出“pisa”根路径(以便它通过相对路径找到字体文件)
就我而言,它是这样的,
因为字体放置在 PATH_TO_DJANGO_PROJECT/files/arial.ttf
I faced the same problem with cyrillic characters.
The solution contained two steps:
1. Point out the font file in your HTML file
2. Give "pisa" root path (so that it find font file by relative path)
in my case it was something like this
because fonts were placed at PATH_TO_DJANGO_PROJECT/files/arial.ttf
我正在使用 xhtml2pdf 版本 0.2.4
我遇到了同样的问题,我能够使用这种编码来解决:
然后在我看来,我定义如下:
我的 HTML:
I am using xhtml2pdf version 0.2.4
I faced the same issue and I was able to resolve using this encoding:
Then in my views, I have defined like:

如果您调用 createPDF 而不是 pisaDocument 方法,则可以使用
If you are calling createPDF instead of the pisaDocument method, you can use
