Generating pdf with wkhtmltopdf Django

I'm trying to create a pdf with this library implementing the most simple example of de docs

using the url and render directly from the template like this

url(r'^pdf/$', PDFTemplateView.as_view(template_name='my_template.html',
                                       filename='my_pdf.pdf'), name='pdf'),

this is the html of the template file

<!DOCTYPE html>
<html>
 <head>
    <title>Hello Wold</title>
 </head>
    <body>
       <p>My First Pdf</p>
     </body>
</html>

but when i try the url the error is this

AttributeError at /pdf/ 'NoneType' object has no attribute 'endswith'

how can i fix it

this is the Traceback

Traceback: File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response 139. response = response.render() File "/usr/local/lib/python2.7/dist-packages/django/template/response.py" in render 105. self.content = self.rendered_content File "/usr/local/lib/python2.7/dist-packages/wkhtmltopdf/views.py" in rendered_content 123. delete=(not debug) File "/usr/local/lib/python2.7/dist-packages/wkhtmltopdf/views.py" in render_to_temporary_file 78. content = make_absolute_paths(content) File "/usr/local/lib/python2.7/dist-packages/wkhtmltopdf/utils.py" in make_absolute_paths 151. if not x['root'].endswith('/'):

Solution

Looks like you have a problem with your root path. Try settings STATIC_URL in Django setting file (settings.py)
