Dynamic subdomain

Dynamic subdomain

Hi,

Is there a way to implement dynamic subdomain with Flask ? I'd like to
do something like that:

python.example.com
apple.example.com
-> get the subdomain name and do something with that

instead of
example.com/apple

Hi,

Extra parameters you pass to @app.route() and friends are passed 
directly to Werkzeug’s Rule class:
http://werkzeug.pocoo.org/docs/routing/#werkzeug.routing.Rule

You can restrict a rule to a given subdomain pattern, and this pattern 
can contain variable parts the same way that URL patterns do:

@app.route('/foo', subdomain='<bar>')
def foo(bar):
# ...

Hi,

Thank you for your answers. The Site object is pretty interesting.

About passing the subdomain to the route, this is what I expected. But
I tried to implement it in a simple app without success :

http://paste.pocoo.org/show/342835/

This example don't work either on

fr.localhost:5000
en.localhost:5000
or
localhost:5000

Am I missing something ?

N.

Your example works fine if you add fr.localhost and en.localhost to your 
/etc/hosts file.

Gosh ! I forgot to make the changes. I think it's coffee time :)

Thank you for your helpful answers.

Create a context processor that injects 'request.host' into your
templates and branch accordingly.

For more control, you could create a Site object, instantiated from
the current request, and add properties to that, for example:

class Site(object):
  def __init__(self, request):
    self.host = request.host

  @cached_property
  def google_analytics_id(self, default=''):
    if self.host == 'python.example.com':
      return <something>
    elif self.host == 'apple.example.com':
      return <something else>
    return default

Then use site = Site(request) in your context processor and refer to
site.<attribute> in your templates. Candidates for other properties
might be HTML meta description and keywords, the site's title etc.
This kind of branching is only possible from parts of the application
that have access to the request object, of course.
