我正在构建一个项目，我需要从模板（html）将我的数据转换为pdf，我的问题是图像不是在pdf视图上。这是我的代码：
class GeneratePdf_month(TemplateView):
template_name = "polls/info_month.html"
def get(self, request, *args, **kwargs):
## do some....
data = {
'cliente': cliente,
}
pdf = render_to_pdf(self.template_name, data)
return HttpResponse(pdf, content_type='application/pdf')
## and this is my html template
<head>
{% load staticfiles %}
<title>Detail</title>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
padding: 10px;
}
</style>
</head>
<body>
<header>BlaBla<img src="{% static 'polls/images/image.png'%}"></header>
</body
有人能帮我吗？
如果你正在使用html到pdf，你还需要提供链接回调以便能够显示图像：
def link_callback(uri, rel):
"""
Convert HTML URIs to absolute system paths so xhtml2pdf can access those
resources
"""
# use short variable names
sUrl = settings.STATIC_URL # Typically /static/
#static Root
sRoot = settings.STATIC_ROOT # Typically /home/userX/project_static/
mUrl = settings.MEDIA_URL # Typically /static/media/
mRoot = settings.MEDIA_ROOT # Typically /home/userX/project_static/media/
# convert URIs to absolute system paths
if uri.startswith(mUrl):
path = os.path.join(mRoot, uri.replace(mUrl, ""))
elif uri.startswith(sUrl):
path = os.path.join(sRoot, uri.replace(sUrl, ""))
else:
return uri # handle absolute uri (ie: http://some.tld/foo.png)
# make sure that file exists
if not os.path.isfile(path):
raise Exception(
'media URI must start with %s or %s' % (sUrl, mUrl)
)
return path
并且不要忘记在render_to_pdf中添加链接回调：
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, link_callback=link_callback)
if not pdf.err:
return HttpResponse(result.getvalue(), content_type='application/pdf')
return None
您还需要在img标记内指定高度和宽度，如：
<img src="{% static 'polls/images/image.png'%}" alt="image" width="200" height="150" />
在settings.py中，不要忘记定义STATIC_URL和STATIC_ROOT，MEDIA_URL和MEDIA_ROOT
例如这样的例子：
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR,'project_name/static/')
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR,'project_name/media/')
然后别忘了在终端上运行python manage.py collectstatic
