The ordering of your patterns matters, so that is done at config time. However it's very common to want to have unrelated code executed depending on the type of request to a URL. Pyramid will do this lookup for you, rather than polluting a gigantic view function with multiple code-paths for distinct functionality.
@view_config(route_name='hello', request_method='GET')
def get_hello(request):
return Response('a GET request for %s' % request.matchdict['name'])
@view_config(route_name='hello', request_method='POST')
def post_hello(request):
return Response('stored info')
config = Configurator()
config.add_route('hello', '/hello/{name}')
config.scan()
app = config.make_wsgi_app()
- mcdonc 15y agoBottle and Flask actually allow for this too. Bottle's variant: @route('/hello/:name', method='GET') def hello_get(name): return 'Hello %s' % name @route('/hello/:name', method='POST') def hello_post(name): return 'Hello %s' % name Pyramid permits a larger variety of predicates (including custom ones), however: https://docs.pylonsproject.org/projects/pyramid/1.2/narr/viewconfig.html#predicate-arguments https://docs.pylonsproject.org/projects/pyramid/1.2/narr/vie...
- mmerickel 15y agoYes but while implicit route ordering works a lot of the time, I'll gladly keep Pyramid's concept of explicit ordering, which is the main source of verbosity in the Pyramid setup which separates routes from views.
- mcdonc 15y agoThe order the decorators are run at import time is explicit. Everybody loves module-scope programming and import-time side-effects! What's wrong with you man? ;-)
