Fresh blank version of web2py, in default controller:
def report():
import os
response.title = "web2py sample report"
# include a chart from google chart
url = "
http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=500x200&ch1=Hello|World&.png
"
chart = IMG(_src=url, _width="250", _height="100")
# create a small table with some data:
rows = [THEAD(TR(TH("Key", _width="70%"),
TH("Value", _width="30%"))),
TBODY(TR(TD("Hello"), TD("60")),
TR(TD("World"), TD("40")))]
table = TABLE(*rows, _border="0", _align="center", _width="50%")
if request.extension == "pdf":
from gluon.contrib.pyfpdf import FPDF, HTMLMixin
# create a custom class with the required functionalities
class MyFPDF(FPDF, HTMLMixin):
def header(self):
"hook to draw custom page header (logo and title)"
# remember to copy logo_pb.png to static/images (and remove
alpha channel)
#logo = os.path.join(request.folder, "static", "images",
"logo_pb.png")
#self.image(logo, 10, 8, 33)
self.set_font("Arial", "B", 15)
self.cell(65) # padding
self.cell(60, 10, response.title, 1, 0, 'C')
self.ln(20)
def footer(self):
"hook to draw custom page footer (printing page numbers)"
self.set_y(-15)
self.set_font('Arial', 'I', 8)
txt = 'Page %s of %s' % (self.page_no(),
self.alias_nb_pages())
self.cell(0, 10, txt, 0, 0, 'C')
pdf = MyFPDF()
# create a page and serialize/render HTML objects
pdf.add_page()
pdf.write_html(table.xml())
#pdf.write_html(CENTER(chart).xml())
# prepare PDF to download:
response.headers['Content-Type'] = 'application/pdf'
return pdf.output(dest='S')
# else normal html view
return dict(chart=chart, table=table)
I thought it was the logo so I commented it out, but still the exact same
error.
Looks like it is failing here:
def _parsepng(self, name):
#Extract info from a PNG file
if name.startswith("http://";) or name.startswith("https://";):
import urllib
f = urllib.urlopen(name)
Which I am not sure why considering there is no PNG in my code so I guess
it is doing something behind the scene. I even commented out the chart line
so there should be no image issues.
