How to set smart url in zend framework?

How do I manipulate subdomains with Pyramid's url dispatch?

• I can not seem to find any documentation on working with subdomains with the Pyramid framework. There is one question/answer on SO regarding this (http://stackoverflow.com/questions/5274813/routing-subdomains-in-pyramid) where they say "Theoretically, this is covered by add_route() with a pregenerator argument." I have also found in the docs (http://docs.pylonsproject.org/projects/pyramid/en/latest/api/interfaces.html) where they mention subdomains under the interface IRoutePregenerator __call__(request, elements, kw):  " The pregenerator for a route is called bypyramid.request.Request.route_url() in order to adjust the set of arguments passed to it by the user for special purposes, such as Pylons ‘subdomain’ support." But these are the only places that even mention subdomains and there is nothing on how to work with them. All I am wanting is to have a wildcard DNS accept any subdomain. If subdomain is user, route to a certain controller, if the subdomain is any other word, route to a controller and provide the subdomain as a variable. This is super easy with Flask: mod = Blueprint('users', __name__, subdomain='user') @mod.route('/') code or @mod.route('/<var2>', subdomain='<var1>') How can I/is it possible to achieve this with Pyramid?

  I needed to do the same and found the solution towards the end of the route_url documentation (http://docs.pylonsproject.org/projects/pyramid/en/latest/api/request.html#pyramid.request.Request.route_url). You need to add keys for _host and _scheme within the kw object that you return from your pagegenerator callable. Mine looks like this: def subdomain_pregenerator(request, elements, kw): # pop the store name from the kw and append the _host including # the store name as the subdomain store_name = kw['traverse'][0] kw['_host'] = '{0}.{1}'.format(store_name, request.host.split(':')[0]) kw['_scheme'] = request.host_url.split(':')[0] kw['traverse'] = kw['traverse'][1:] return elements, kw for a route definition that looks like this config.add_route( 'store', '/*traverse', factory=StoreFactory, pregenerator=subdomain_pregenerator)
