Re: TypeError Exception Value: coercing to Unicode: need string or buffer, dict found

2012-05-23 Thread Waleria 
It shows this line:

File "C:\simuladores\..\simuladores\detector\views.py" in pdf
  259. canvas.print_pdf(response, facecolor='w', edgecolor='w')
File "C:\Python26\Lib\site-packages\matplotlib\backend_bases.py" in
print_pdf
  1334. return pdf.print_pdf(*args, **kwargs)

In my code this line is: dir(canvas.print_pdf)
canvas.print_pdf(response, facecolor='w', edgecolor='w')

but I do not know about solving.

parameters directly in the function

2010-06-10 Thread Waleria 
Hello!!!

I'm Walériai have a question about a functionsi have a
function bellow:

y.append(pow(form.cleaned_data['Pinc'],2)/(2*(pow(2*pi*v,
2)))*((pow(2,2)*pow(form.cleaned_data['Qe'],2)))/
(pow(form.cleaned_data['fp'],2))*(pow(form.cleaned_data['df'],2)))

I need to pass this parameter (2 * pi * x) directly on the function
but displays an error: unsupported operand type(s) for /: 'Decimal'
and 'float'

As i do?
