Pyramid Captcha
Project description
Pyramid Captcha
This Python package provides a captcha implementation for use with the Pyramid Web Framework. It is based on the captcha library and uses Pyramid sessions for captcha validation. Please refer to the documentation for further information.
Usage
To generate a captcha, you have to import the class Captcha
.
from pyramid_captcha import Captcha
The simplest solution is to use this class directly in your view definition.
config.add_route('captcha_generate', '/captcha')
config.add_view(
Captcha,
attr='generate',
route_name='captcha_generate',
request_method='GET'
)
In this case, the route /captcha
will return a captcha image
with the default length of 6 characters. If you want to adjust the
captcha properties, you have to wrap it into a view callable, for
example to change the number of characters.
def generate(request):
return Captcha(request, length=4).generate()
The generated captcha value is stored in the current session. It
can be checked against a submitted form value using the
validate()
method.
try:
Captcha(request).validate()
except CaptchaError as e:
raise HTTPForbidden(e)
Demo
You can check out the code and run a little demo by calling
make serve
.
