With some fanfare Google Web Apps have been launched. This is great because its using Python and Django, how much more perfect can it get. This morning I've been having a play and I'm just waiting for my account so I can upload something.
Would be nice to take my (as yet unreleased) Plone to Django conversion script, plonk the result on Google Web Apps and then link up a nice little Adobe Air app. Anyway two things that irked me (of course I'm going to complain): 1) the example Python all has two spaces as the indent and 2) it uses Django templating.
Fortunately it says:
You can bundle a framework of your choosing with your application code by copying its code into your application directory
And looking at later comments, it's not going to block a module like simpletemplates, which I use for templating in Django. So. lets alter helloworld.py a bit (original):
from simpletemplate.google import DjangoSimpleTAL
And change the MainPage class to read (only changed last two lines):
class MainPage(webapp.RequestHandler):
def get(self):
greetings = Greeting.all().order('-date')
if users.get_current_user():
url = users.create_logout_url(self.request.uri)
url_linktext = 'Logout'
else:
url = users.create_login_url(self.request.uri)
url_linktext = 'Login'
template_values = {
'greetings': greetings,
'url': url,
'url_linktext': url_linktext,
}
path = os.path.join(os.path.dirname(__file__), 'index.html')
template = DjangoSimpleTAL(path)
self.response.out.write(template.render(template_values)
And finally lets change index.html to read:
<html>
<body>
<tal:loop repeat="greeting greetings">
<tal:block condition="greeting/author|none">
<b tal:condition="python:greeting.author.nickname">Author</b> wrote:
</tal:block>
<tal:block condition="not:greeting/author|none">
An anonymous person wrote:
</tal:block>
<blockquote tal:content="greeting/content">Comment</blockquote>
</tal:loop>
<form action="/sign" method="post">
<div><textarea name="content" rows="3" cols="60"></textarea></div>
<div><input type="submit" value="Sign Guestbook"></div>
</form>
<a tal:attributes="href url" tal:content="url_linktext">Login</a>
</body>
</html>
And things seem to work just dandy. For those who do use simpletemplate, the google module isn't in SVN yet, and needs a bit of work, but just a quick refactoring of the simpletemplate code to be friendly with the new imports that the Google app server uses.
Update: by the time my blog post was done, my account was activated. Unfortunately I have to work today though.
