|
|
|
Usage:
|
|
|
|
- Use the view from a page to generate an image tag and/or an audio
|
|
URL. Use the 'image_tag' and 'audio_url' methods for these.
|
|
|
|
- Place the image tag and/or audio url in the page
|
|
|
|
- The image tag will load the captcha for the user, or the user will
|
|
use the audio url to listen to the aural captcha.
|
|
|
|
- The user will identify the word, and tell the server through a form
|
|
submission.
|
|
|
|
- Use the user input to verify.
|
|
|
|
The view will ensure that captcha state is preserved until verification
|
|
has taken place. The image tag and audio url for a given instance of the
|
|
captcha view will give the same word.
