 Is there a way to just send mail and not redirect the page?

 I'm trying to send mail using a ajax popup window, so I want to submit
 and write a message in a div, and dont want the page to reload/
 redirect.

You can write a handler that sends an email, and POSTto it the content
of your div using JavaScript.

[google-appengine] Re: how to submit form from static index.html

[Alexander Kojevnikov]

 here is how i have setup the app.yaml, email.py and form.html, let me
 know whats wrong ??, how should i setup handler for email.py in
 app.yaml ??

OK, here's how you can do it.

app.yaml:
-
handlers:
- url: /send-email
  script: email.py
- url: (.*)/
  static_files: static\1/index.html
  upload: static/index.html
- url: /
  static_dir: static
-

email.py:

from google.appengine.api import mail
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app

class SendEmail(webapp.RequestHandler):
  def post(self):
user_address = self.request.get('address')
if mail.is_email_valid(user_address):
  sender_address = 'y...@example.com'
  subject = 'test'
  body = test email
  mail.send_mail(sender_address, user_address, subject, body)

self.redirect('/form.html')

application = webapp.WSGIApplication([('/send-email', SendEmail)],
 debug=True)

def main():
  run_wsgi_app(application)

if __name__ == __main__:
  main()


form.html:
-
form action=/send-email method=post
Email: input name=address type=text/
input type=submit value=Send/
/form
-

I didn't test it, let me know if something doesn't work.

Regarding this line in your original code:

# prompt user to enter a valid address

You have quite a few options, the easiest one is probably to redirect
to a static page containing an error message and a link back to the
email form. Other options will probably involve templates or and/or
some javascript.

Also note that the sender_address must be the administrator of your
app or the currently signed in user:
http://code.google.com/appengine/docs/mail/overview.html

Hope this helps.

Python standard library has an escape() function but apparently
doesn't have unescape().

You can use this code or google for a better solution:
http://blog.modp.com/2008/10/html-unescape-in-python.html

By the way, why do you use JavaScript for this? You can try a simple
textarea instead:

form action=/send-email method=post
Email: input name=address type=text/br/
Message:br/
textarea name=data rows=10 cols=20test/textareabr/
input type=submit value=Send/
/form

This way you don't need to unescape() the message.

This is easy to do. See the mail api http://code.google.com/appengine/docs/mail/
for details.

No, but you can write your own handler. Use the code from the tutorial
as a starting point.

In your index.html change the form's action for example to /send-
email. Then in your send-email handler, override the post() method,
send an email using the appengine mail API, and finally redirect back
to the html page with:

self.redirect('/your-page.html')

Don't be afraid to throw in some Python code, it's really easy. Let us
know if you have troubles setting this up.
