How To set up a route with route variables appearing in any order in query string.

[afrotypa]

how do you set up routes to match a url structure with query strings
where the route variables can appear in any position in the query
string?

i.e. which route will match all 3 of these urls and cause the
controller/action to be called with var1=1, var2=2, var3=3?

/controller/action/?var1=1&var2=2&var3=3
/controller/action/?var2=2&var1=1&var3=3
/controller/action/?var3=3&var2=2&var1=1

Will I need some advanced routes feature such as a 'function
condition' to make this happen? Or is there some more obvious (and/or
simplified) way (i.e regular expressions?) to accomplish this, which I
should be looking at?.

You could access these parameters with default routes using request.GET.

.pk.

You mean simply use

map.connect('/{controller}/{action}')

and then call request.params in the action to extract the query
variables directly from the request?

Perhaps that will work...

There isn't a built in feature for that in Routes.

But you can use wildcard (*) and then split the wildcard using '/'.

By doing this, the "wildcard params" are stored in array, so that you can sort them however you like to fulfill your requirements.

Exactly, request.params is a multidict with all the QUERY_STRING parameters.

.pk.

Thanks!.

Routes does not look at the query string, only the URL path. There is
no way to pass query parameters as action arguments.

Well, you could theoretically set a callback function
"map.connect(..., condition={'function': MY_FUNC})", and it could
parse the query string and stuff the variables into the match dict.
But I don't know if webob is set up at that point so you'd have to do
it manually.
