Replacing a parameter in the current route

[scottkf]

Is there an easy way to accomplish this without reusing the code in the prototype.run function? It doesn't seem like it, but I could be blind! I'm trying to programmatically redirect something, but change a parameter.

A request has a redirect method already see the docs.

I'm not entirely sure what you mean by "programmatically redirect something, but change a parameter", do you want to re-run the same route but add a parameter if it is missing? This could be achieved with some route middleware, e.g.

var paramChanger = function (req, next) {
  req.params.foo += 1
  next(req)
}

this.get('/somepath', paramChanger, function (req) {
  // do whatever with req.params.foo now
})

More on this in the docs. This wouldn't re-run the route but do the massaging of the params before your route is run…
